I'm still new to smartphones/Androids...
After experimenting with the lastest update, it appears to me that turning on the hotspot option automatically turns off WiFi reception, and vice versa. If I'm wrong about that, please let me know.
Otherwise, I was a surprised and a little disappointed at that, since I can think of several instances in which it would be very useful to establish a wireless connection to the G2, and then re-serve that out as a hotspot.
I'm wondering if it's a hardware, legal, software, or simple greed reason that prevented TMO from making that option available?
Yes the hotspot feature doesnt serve as a repeater of sorts for wifi, it simply turns your 3G 4G signal to wifi. Imagine if you could do that though. You could share your wifi to yourself and somebody on another device could make a wifi call through your wifi, being repeated through your router. Clearly this would cause a glitch in the time/space continuum.

Are you for real? To create the hotspot you're using your wireless card, the same one you'd normally be using to connect to wifi. Greed has little to do with this short of the phone only having a single wireless card. But no worries, laptops can't do this, either, unless they have a second wireless card.
It's a hardware limitation. The wifi chip can only do one thing at a time: either connect to an existing wireless network as a client, or serve it's own internet. Not both.
Got it. Thank you!
first id like to say lol to the time space joke
next... why on earth would u even want to get a wifi signal from ur g2... and then broadcast the signal you get from the wifi? why not just connect whatever your gonna connect to the g2 straight to the source..?
If you are on an airplane using Wifi (which is paid, and usually cheaper from a phone than from a laptop), and someone you want to broadcast that Wifi signal to your laptop and a partner's laptop --- thus not paying twice. It could be useful then.
You can do one laptop with wired tether, but not two or more.

Well, I know now that re-serving/repeating a wifi signal is a physical impossibility with the G2; however, to answer your question, there are several instances where such a capability would be useful:
1. Our company's wireless network is pretty secure. We do also have a server for guest access but the password changes daily. So, if a vendor or other person drops by and wants to show me a demo or catalog that's on-line, I have to hunt down a tech guy who knows today's password. That's been a bit of a time-waste to me in the past.
2. I'm on the road with a few colleagues. I get my hotel room's wireless access set up but I sometimes have to fiddle with my other various wireless devices to get them to work and a colleague might bring a laptop over to my room if we want to work on something. It's not unusual these days for road warriors to take a wireless router with them just for these circumstances.
3. I'm at the airport with a couple colleagues and we're all working. If we all need to get on-line, we each have to buy an hour's access (which never, ever gets fully used) at $10 a pop.
4. I'm at some research facility or client's and I manage to get the wireless key for their network. But, while I'm there, other colleagues drift in and out and it's always another mad dash for them to find the sacred piece of paper with the key.
Now, there are various ways to solve all of the above (and all of them are real-world experiences), but by in each case the easiest and most economical would be for me to re-serve a wireless signal and give my key to my vendors/associates, if the G2 actually had that capability. I know it doesn't and can't now.
Still love it, though.
There's nothing wrong that mobile hotspot and wifi can't co-exist (one is server and another is client).
Same thing happens on my nexus one.
dude seriously

Dude seriously... its called an ad-hoc network... you tether your phone to your computer and then broadcast an ad-hoc network from your computer and there you go... I've used this for counter-strike lan games with 8 players before on the g1 and the moto cliq and my g2... goggle how to set up ad-hoc
hi, i just want to know if is there any solution to use Tethering (on Froyo) like a wifi repeater? can i do it? thanks
SOrry for bad english
Just in case anybody cares.. thought I'd throw in my 2 cents after having it for a couple hours.
My last phone was the Tmobile galaxyS 4g . First as far as size.. normally I may have an issue with it but being so thin and light and the beauty of the screen makes up for the footprint. Biggest improvement for me would be internet cruising.. screen size/font size and general slick and quickness makes it a huge benefit over older phones for browsing. I typically use my tablet for light couch browsing.. but this phone may possibly change that. Flash video loading .. for example justin tv or twitch tv is insanely fast close to desktop speeds. Netflix works like a champ as well. Everything at this point has been pretty much instant.. this phone is bloody fast especially for being right out of the box.. will be cool to see how custom roms and kernels will do with it. Oh yeah and the gps is super quick to lock on.. 10 seconds or so versus an inconsistent 1 to 2 minutes with the original galaxy.
I would have to say the only downside of this for me is the network speeds.. 3g speed test in my area show if I'm lucky 1mb at best.. and 3-4mbps with 4g. My tmobile was a solid 5+mbps at the very least.. I traded tmobile's faster yet limited network for Sprint's slower yet steadier and consistent wider spread network.
Thanks for your initial impressions. I'm also making the switch from T-Mobile to Sprint and knew I'd have to compromise with network speed. T-Mobile's HSPA+ is pretty damn fast and Sprint has paused their WiMax rollout. I had an Evo before returning it and noticed that WiMax was tough to get indoors. I'm hoping Sprint will be making a major infrastructure transition over to LTE (it's in the plans) and by switching now I'll grandfather into a nice unlimited plan.
25% off monthly, unlimited data, nights @ 7pm, unlimited mobile to any mobile, google voice integration made the switch pretty easy for me.. but I don't expect data speeds to be that impressive
25 percent off? that'd be great.. how? Sprint guy told me to join a local credit union and I'd receive 10 percent off.. I thought that was great.
Also yeah it kinda sucks about Wimax.. are they going to transition completely away from it?
I think data speeds have been getting worse for Sprint as Boost and Virgin mobile get more popular .. that's alot of data usage
I don't understand why wifi calling is so important to people. Especially if it means you can have multi window without it. Anyways doesn't everyone have unlimited minutes these days?

For me its the fact that reception is horrible in my apartment, if you go outside its fine. I dont like going outside just to make a call every time so the wifi calling gives me reception inside.
Reception is the issue

I live out in the boonies absolutely no signal within a few miles from the house. Wish I didn't have to have it esp since I love that All Star so much.

I live in a townhouse within viewing distance from a cell tower and yet in my house I can get maybe 1 signal at one of the house (sometimes none at all). If I wanted to make a call I had to go to the garage. So wifi calling is important to me.
I'd be willing to sacrifice wifi calling for a multi-window rom if (and only if) I found a reliable option for wifi calling that's free, because t-mobile's wifi calling works very well for me.
It ABSOLUTELY is reception for many people. T-Mobile's fantastic when you get a good signal, but step inside any building made of concrete, or a brick house, or a house with other signal attenuating characteristics and you're screwed, dead zone. It's why I dumped TMo a couple of years ago, though I came back to try their Note II and newer HSPA+42 data service.
My office building is still a data dead zone, but voice calls come in if I'm near a window. My house, though, TMo's gone from a dead zone two years ago to a full-bars signal.
I went to south dakota a few weeks ago to visit my brother and his family.. t mobile, Verizon, Sprint and att reception there is abysmal.. if it wasn't for Wi-Fi calling i would've been screwed.. it's so bad there i asked my brother, "how do u deal with this reception?" Seriously i had zero bars from Irene sd to sioux falls sd if it wasn't for Wi-Fi i wasn't gonna be talking to anyone...

minutes aren't free. still eats into your monthly rate plan for minutes, but providers better reception. my house has horrible to no signal so I use wi-fi calling not necessarily so people can call me, but so my phone doesn't eat up battery looking for network all the time.

If you are on an eligible plan you can add the free wifi calling as a additional service. My grandfathered preferred plan won't allow the free wifi calling service... It deducts minutes from my allotment. There are parts on my house that get poor reception so I use it for that purpose.

You can add the feature but it will use your minutes. Prepaids "do not" qualify for this plan. The only benefit for prepay to activate this feature is if you have poor reception this will allow you to still make a phone call.
As others have said, it is free and won't use up your allotted minutes only if you are on a qualifying plan.

I will give you a more detailed run down.
Actually under a corp plan all wifi calls are free if you add it to that account. Also it doesnt always take mins away. Its more like 70 no 30 yes. From my testing over the last two years.
I work in network security which means I'm in a lot of "heavy secure "wink wink" data centers etc that have zero cell signal for a reason. They use to even bar camera phones. These days they just put a really thin tape over your cameras front & back. So if you even tried removing partly before seeing the "SO" at the exit it will tear and then you got big issues. That being said voip coms are allowed as long as their tied to your imei number like T's.
So wifi calling is needed when I and my guys are at those locations. Other uses as many have said is reception from a poor signal. Tmobile has a great network in the city, its when u get out in the boonies where there's nothing alot of the time. Those times I just click on my VZW MiFi and make call that way or pull over at a McDonalds. Kinda of a end around but being with T allows us alot of flexibility where the other carriers relies on there massively fake reception maps.
Tmobile is great in that it also allows me personally to swap phones easy.
There kinda like a rich man's garage with a dozen super cars, I wake up and pick at will what phone to fly with that day. Doing that on VZW is a pain. Plus the cost for corp plans with Tmobile is about one third of that of VZW or the Death-Star. The only option the other providers have is a wifi extender which requires and hard line and a GPS signal. Try getting that through x amount or so feet of concrete.
As a side note with reception where in the middle of nowhere Ky the only cell and data service was Tmobile.
Typically for me what phone I use depends on what Rom its on. I love cm9/10 but as everyone knows it doesnt support T's wifi calling features. So if im going to be in a secure environment I will have to grab one thats on a samsung kernel with wifi calling. Sometimes I can get away with wifi/google voice or my corp voip pbx but nothing compares to T's 93kb voice codec period.
We never get the excuse that "I couldn't call in cause there wasn't signal" from my guys. So productive has gone up a fare amount due to this tech it also allows better live tracking cause T's employee finder works over any data connection even when outside gps isnt available. So there's more security that my guys feel as we always know where they are if something like a "misunderstanding" comes up.
Does that help? Lol.

Lol ya that explains it a lil. I live in Las Vegas and I never lose signal anywhere. I guess that why I never understood. But when people are saying no reception is that mean no data either? Cause even if you have no reception but have data. Can't you use a 3rd party app that makes calls over data (not wifi)
Cell and data are basically the same as voice runs over the data lines pulled to the towers. It will be even more so as carriers upgrade to LTE-rev14 I think which is from my understanding is pure carrier level voice IP network vs switched network now.
Basically now voice is segmented out to a Nortel, Lucent, Alcatel gear to handle the phone side and then data is routed to their respective network gear. In a pure IP network both voice and data are run data only. Voice will be filtered out with QoS rules with along with virtual pbx box vs the circuit switched like we have now. The advantages of going pure IP are
1) Carriers are no longer tied to large circuit switched gear that runs into the millions and is proprietary to each manufacturer's specs. So the carriers try to buy just one type of pbx so not to run into compatibility issues. Just replacing a line card which typically hosts 129 lines at the "CO" known as central office is always same day aired if they don't have a replacement handy and those cards run 5 or so grand a piece. So downtime is a problem and cost vs ROI is as well.
2) In a pure voice IP setup the carriers can run a virtual PBX that is software bound vs hardware that the call is then routed via data to CO or datacenter to the last leg to terminate the call with say level 3 being your terminating host that then routes the call from there. If that call is cell phone to cell phone then it can stay data the entire way. This cost the carriers fare less as the hardware is agnostics, think vmware etc. Also audio codec on the BOX and towers can be adjusted in learning mode and then into dynamic mode as to give the callers the best overall call experience and if the tower gets loaded down with calls that gear can downgrade to a lower codec to handle more call volume. Think rush hour traffic where your stuck and everyone is on their cell. I could go into more details but you would fail asleep but this killer feature alone.
Bottom line is this cost the carriers far less, the audio codec used has much better call quality and can be setup to be dynamic to the load of individual towers vs switched which is hard coded. Downtime is dramatically reduced as there's no actual phone/linecards to go bad.
Many T-Mobile users "use" the Wi-Fi calling feature because it just sounds better. The reason that is because the audio codec "your call" runs around 96kbs. With voice over LTE "depending on tower config and load" can provide the same call quality. For example vzw cell call is 4.7kbs "data" which means that call is heavily compressed. You can tell if you listen, the bass and highs are gone. It's like talking to someone that speaks monotone. The reverse, GSM to GSM call uses a audio codec in the 14.8kbs range and sounds awesome. Even better is two T-Mobile callers using Wi-Fi calling. The problem the carriers have is CDMA to GSM or the other way around, all those calls sound like crap cause the voice gear has to downgrade or upscale to meet the setting of caller and vzw doesn't scale higher than 9.2kbs so the convo sounds mutilated with call echo, drop data packets which sounds like garbage like distorted audio. Think Sat radio when you go under a long bridge. Voice over LTE "voice over data" will allow all carriers gear to talk correctly and adjust audio codecs correctly on the fly giving the callers the best call possible.
I know I went WAY beyond and in depth but I love this stuff and its fun to share it with others.

Reception is one thing, but there is another reason..
For people that travel frequently outside the Tmobile coverage area (ie: International).. Wi-Fi calling is important and critical.. Even with a Corp plan, international minutes when you need to call back to the US is expensive and without having to deal with call forwarding, or grabbing a local SIM.. (though I usually get one for data)
Since I'm pretty sure others here have used their ZLs for tethering via portable hotspot (I hope), has anyone had Internet speed issues when using the phone as a portable hotspot (from the perspective of the tethered device)?
Here's the whole story -- both myself and my husband have the ZL (6506). He has a tethering-permitted data plan with AT&T, and he uses the portable hotspot feature to tether to his Galaxy Note 10.1 tablet. He previously used the same functionality on the Galaxy S3 without issue, however since switching to the ZL, he's had serious lag in the Internet connectivity on the tablet. It seems to be a function of power saving features, because when the phone is plugged in and charging, the speeds are decent, but when the phone isn't plugged in, they begin to degrade. They get worse when the screen shuts off, too. We've checked everything related to sleep settings, Wi-Fi, etc -- everything to keep it all "awake" while using the hotspot to no avail. The data speeds become worse than dial-up and connectivity is very choppy. Stamina mode is disabled, as is low battery mode.
So, I'd like to know if anyone else has seen this on the ZL? I'd test it on my own phone, but I am not on a data plan that allows tethering.
I'm asking because we also suspect that this phone may have some bad hardware or a firmware issue (related to 2 now-dead microSD cards within the span of 1 week, but that's another story) -- if he is alone in this problem, then perhaps it's just a bad unit overall & it should be replaced or repaired. He's going to try repairing the firmware via PC Companion later today.
Thanks in advance!

I haven't tested this for you but as far as I know, your factory unlocked phone can use this function without any tethering data plan because your phone is not restricted from tethering comparing to locked phones.
So the fastest way is to test it yourself.

True, sort of. As I understand it, AT&T is still capable of blocking tethering with unlocked phones -- not on the phone itself via a tethering manager, as they do on AT&T locked phones, but certainly the network traffic, if it isn't masked, can be blocked. I suppose I could try FoxFi to mask the traffic, but that's a whole lot of hassle and risk (I'd rather not have my contract canceled, thanks) for very little reward.
I'm mostly wondering if anyone else has noticed an internet speed issue when using the portable hotspot on the ZL (even on any of the other models, not necessarily the 6506), especially when the phone goes to sleep. If you don't have a ZL in your hands yet, then you can't really help me .
I used stock tethering apps on unlocked and att phones. I have the unlimited 30 dollar plan that does not allow tethering

Did either of you notice anything with upload speeds (especially if you run speedtest)? What we're seeing seems to be intermittently poor or nonexistent upload speeds when tethering a tablet to the ZL via Wi-Fi portable hotspot.
Bluetooth / WiFi Tether
Interesting post...
I usually tether over bluetooth, and while I'm pretty new to this device I know that I have had trouble trying to tether with various devices over AT&T before. I have a grandfathered unlimited data plan, and rarely tether, but once (~ a year ago) I received messages stating that if I attempt to tether again than my data plan would be changed to a tethering plan (limited data & much more expensive).
On my previous phone (HTC One X+, stolen) - i had to change a line in the telephony.db from 'broadband' to 'pta' in order to avoid this. ( I think the argument was that 'broadband' notified AT&T that the device was being used as a hotspot and 'pta' acted like it was a cell phone accessing the data..
I am currently using the PAC (Paranoid/AKOP/CyanogenMod rom) at the moment, and it will allow me to tether, but is there something I can change so that AT&T won't be (so readily) alerted about it?
I've used pixel phones for the past 4 years and both my Pixel 1XL and 3XL both do not kick over to Wifi calling until the signal was horrid (-120db +) on standby. I frequent lots of areas where the signal is sub par, but usable (-110 to -120db). The major issue with this logic is that you start a call on the network (in my case VZW) and shortly after the call connects to the person on the other end it kicks onto Wifi Calling. This is NOT a smooth transition. There is a 1-2 second 'blip' that causes the audio to cut out and I have to repeat myself... which is incredibility frustrating. I could turn off wifi calling, but then go into places like a basement and loose the call every time. The iPhone on the other hand if it has 1-3 bars and good wifi it switches to wifi and stays parked on wifi until you leave the wifi coverage area or the wireless coverage improves. What determines the signal level that the phones switch to wifi calling? Is it Android or the carrier? Does this differ my phone manufacturer? I'm looking to switch from Verizon to ATT, and ATT doesn't offer an updated LTE Microcell which means I would rely on wifi calling in my basement. I don't want to have the same wifi calling experience I have seen on VZW with a Pixel. Does Oneplus, LG, or Samsung do this better? Is there a root hack I could use to fix the problem?
I've only used it a couple of times as T-Mo isn't good where I'm at. I mean exactly where I'm at. I'm like in a dead zone in my apartment/complex. I get 1-2 bars max, but I can go about 20 yards, and get full bars. Wi-Fi was hit and miss as much as a bad cell signal for me. I tried to use it as "always on", but it didn't matter. I gave up, and ended up getting one of T-Mo's personal CellSpots, so now I get full bars in my place, and never have to use Wi-Fi calling. But to answer your question for me, yes, it sucks to use Wi-Fi calling.
WiFi calling is highly sensitive to your internet connection quality and jitter and also your router. I have had multiple configurations since WiFi calling has come into play. Your wireless router plays the biggest part from what I've noticed and their is so many different ones out there now. Best thing to do first is if you have a computer with a lan cable. Plug it directly into your modem and do a jitter test like this one https://www.fusionconnect.com/speed-test-plus/
Then make a note of what your results are. Now plug everything else back and set it up like your normally would have it and then do the same test over wireless through your router and compare the results to the first test. If they are quite a bit worst than the first results then your router is screwing it up. Most likely it's a premium feature (gimmick) that the router has that is screwing up stuff. I've only had TMobile with WiFi calling but my brother was on Verizon WiFi calling for a bit before switching over to TMobile and once I had a good configuration dialed in with a good internet connection and a good router set up he had no problems except for if he walked out of WiFi range sometimes. We don't have the best LTE signal at the house so the switchover wouldn't always be the smoothest.
Best combo I've tried so far is an Ubiquiti Edgerouter X and then using an Ubiquiti Unifi WiFi access point to give out WiFi. The Edgerouter X has a better type of QoS than most home routers nowadays and it can help WiFi calling issues a lot.
Now I have never experienced this issue you describe with it cutting out upon connection but it does sound like a typical switchover issue where it is switching from wifi calling to LTE or vice versa. Unfortunately that depends on the carrier and how they implement it on their network but I would definitely advise experimenting with your home internet set up if you ever have enough time as that could definitely be a factor as well
I have yet to see WI-FI calling work reliably - ( Engineer w/ 20+ yrs) Another technology pushed to production way too early.
