[Q] Unstable Internet / Network - Touch Pro2, Tilt 2 Android Development

My phone sometimes loses signal completely... other times it has a signal but I cannot connect to the net. The 3G Symbol at the top only shows that it is uploading and not downloading. any Ideas on how i can fix this?

The radio is very flaky, I believe even more so for CDMA devices. What type of phone do you have?

I get the same thing here. Almost 1 out of every 3 times coming out of sleep it is ok. Otherwise I have to go and rebuild the APN settings back to default.
Typically it has something listed but once in a while it lists nothing until I rebuild them.
These times seems like it is like the towers have stopped talking or refuse connection to my phone. Thus the reason why it uploads but not downloading any data.
2.1 had random data issues but 2.2 has some major kink either with the radio version or overall CDMA.
I have Verizon (RHOD500).

I believe it's the (Touch pro2) Rhodium 100. but not really sure how to check. But if you mean GSM or CDMA.. Its GSM

you can try re-flashing the radio, which will help if anything has been corrupted

I would try that if my WinMo has an issue. So far just android dropping data on my RHOD500.
I think it is trying to rebuild or at least re-register on the network too much causing issues with towers or internally at least.

I dnt have a problem in WM. Only within Android.

Yea... the radio drivers probably aren't perfect. Far from it, from the sound of things... I've definitely had issues with it as well. I just try to avoid making calls in Android, and receiving them always makes me leery. I've had a few important calls drop because Android decided to reboot itself...

Ahh yeah I've seen the same problems on my RHOD500...usually I know when facebook gets a refresh API error since its set to sync every hour so I just pop on/off airplane mode for a minute and I get data back.
Other then that radio seems pretty decent...I make and receive calls all day with no issues.

Phantom 3G connection?

I'm using Schaps 4.30 on my tytn and I've noticed that my 3G connection is connecting automatically at random times, especially through the night, and as far as I can tell no programs are open that would use data. The only thing open is activesync. Then I check my bill to find out that it is in fact sending 1k-300k amounts of data. Since I don't have but a 1meg data plan this is pissing me off.
Any help would be greatly appreciated. Thanks.

Well, if you turn off your 3G connection capabilities via the comm manager, it will not only save u battery but none of those random connections will happen either. If u need it on u can easily turn it back on.

Well, sure, I could turn it off at night, I could turn off the whole phone as well. But I'd like to be able to receive my text and multimedia messages.
*edit* The 3G connection itself is not specific to the problem, I just meant a general connection.
Maybe today plugins, like weather, want to update their data? Disable all today plugins and see.

Well SMS and MMS messages can still come thru on Edge...3G is just faster.
You might try this. Got it from here.

Lol, I know messages still come in through Edge, I wasn't meaning to be specific to the 3G connection, just that it's connecting in general.
It did it again last night. I'm going to flash to Schaps 4.31 and see if that helps.
Thanks for the advice guys.

Same Problem
I've got the same problem. I'm using the default HTC WWE ROM. At random times, sometimes twice a day, my "Rogers Internet" data connection (GPRS, EDGE or 3G) connects automatically and doesn't disconnect. If I catch it happening and click cancel, it tries again. It will not give up until the connection has been established for at least 10 seconds.
I've gone through every program I have, checking to make sure the auto update option is disabled (if there is an auto update). I do not use the direct push and therefore, activesync schedule is greyed out.
Any ideas?

AT&T decided that it was my phone and replaced it, sure enough that did the trick. I wouldn't imagine that it's always a hardware issue though, since many people seem to have had this same problem. Simple things like today plugins or maybe just hitting the "X" while signed into MSN Messenger instead of signing out before closing the program. Things like that could contribute to the problem. Hope you're able to get your fixed.
Thanks for the help everyone.
Had the same problems, resulting in extra fast battery drain.
I think I fixed it by flashing a newer radio ROM, but then again my battery still drains very fast since flashing TNT's 6.1 ROM.
Not so sure what's going on...

4G reconnecting issue?

I was wondering if anyone else has this issue. I think most people know by now the issue we all ran into with 4G after we flashed roms with the new OTA update. The 4G would just be stuck at "scanning...." and never connect.
Anyways, I did manage to fix the 4G issue using bigbiff's steps here. So now the 4G connects with no issues but there's one problem: when I leave 4G area or go indoors and come back into 4G area it won't reconnect by itself. I have to either turn on and off 4G or hit the "Scan" button.
If anyone can give me any insight or ideas as to what's going on that would be very awesome.
I have the same problem, and I have seen at least one other person mention this problem (it's kind of hard to search the forum for this problem, since all you get are the folks having problems connecting to 4G).
This started after the OTA update. If the 4G signal fades out, the 4G status remains in "scanning" even in known 4G areas. I made one 4G change to try and fix this - I changed the wimax_idle_sleep time from 10 to 300 as was recommended in the 4G problem posts.
I am wondering if anyone knows what the other 4G settings do and if any of them would fix the problem. So far the only way I know to reconnect to 4G is to turn the radio off and on.
I posted this in another forum, the more frequented one. I thought it was more applicable there since this might be an issue concerning rooting, custom ROMs, home ROM flashing, or all the above. Until I see a wave of non-rooted users complaining about this, I think Sprint has found a gotcha for rooters and flashers. Input from some ROM developers would be nice if they happen to visit this forum.
I can enter a 4g area, turn on 4g, and connect. When I leave a 4g area, turn off 4g, then turn 4g back on before re-entering 4g area and enter a 4g area, it is stuck scanning. It never attaches to the 4g network in the area I entered. If I turn 4g off and on while in 4g area, it will connect.
Are unrooted stock users having these problems? It is a real let down and PITA. Is 4g working perfectly in all scenarios for any rooted user?

I also think it's related to one of the images we have to flash to get root, as the behavior is definitely different than stock. I noticed this after I first rooted / nand unlocked my phone, but before I applied the new radio & wimax. On my phone, however, 4G does eventually come back up. It might take 5 minutes or more, but it does eventually reconnect.
I'm not sure that it's really a bug though. I actually prefer this behavior because it results in fewer dropped connections when switching between 3G and 4G. For streaming apps (Rhapsody, Pandora, Youtube, etc) the frequent switching forces you to have to start the stream over. I think it might have been an attempt to increase the stability of the data connection at the expense of having a 4G connection less of the time. Could be a hold over from one of the older engineering builds we had to flash during the rooting process? It's strange that the behavior persists after flashing a new radio/wimax, but maybe it's actually controlled elsewhere.
Add me to the list. This is from my post about 20 hours ago which hasn't received any bites:
I have seen various issues reported:
1) 4g won't turn on. PERIOD.
2) 4g turns on but only scans - never connects.
3) 3g/4g alternate so there is never a stable connection.
4) 4g turns on and connects but after a while disconnects and won't reconnect until it is toggled on/off with the widget or check box in settings.
I used to have #3 until I did whitslack's "start over" method and now I have #4. I've changed my wimax idle sleep time to 300 in ##data# and verified a good MAC so other than the 2 evo last resort method I think I've tried everything other than the above.
So, does anyone know if renaming/moving macaddress.tree.xml is for my issue #4? Or does anyone know a specific fix for #4?
If it matters I rooted with toast 1/2 and am still on the rooted stock ROM from whitslack's "start over" method.

Some Observations:
I've noticed the following differences since the OTA (with Root-from the "How to Start over with 1.47.651.1" thread):
1. The 4G reconnection problem.
2. Bluetooth no longer auto connects when my headset is in range.
3. I have been getting "Error 67 Data Connection Lost" errors. This error blocks me from 3G data connectivity for a few minutes. During this time, "Mobile Networks" shows "Turning On" in the settings.
I suspect it is one of the following:
a. There is still a radio problem with the rooted OTA
b. the PRI that has not been updated since the root crack matters with this release.
c. Sprint/HTC introduced some new bugs.
d. Some hardware settings need to be tweaked (like the timeout that folks are changing from 10 to 300).
So we need to figure out who is having this problem, and under what circumstances.
I did however note something very interesting. I have repeated this 4 times today. If the 4G disconnects and stays in scanning, if you then place a call it will immediately reconnect. This leads me to believe that it is indeed a setting, and a voice call triggers it (if you recall in May, Sprint was saying that they hope to have Simultaneous Voice and 4G - so there is probably some code to trigger 4G at this point).
What do you folks think.

I would take C out because I have not read complaints by non-rooted users.
The latest PRI is 1.40_003. Right?

I think being rooted currently sucks. One of EVO's greatest strengths, connectivity, has been crippled.

I will try making a call tomorrow when this happens and report back.
I had the same problem pre-root.
I wont be able to help anybody too much with technical stuff 'cause I'm basically a non-technical guy, but I've had the same problem with wimax dropping & not reconnecting ever since the OTA update (1.47....). I went to a Sprint store & the guy just went cross eyed, so it may not be too common.
In my case the connection will SOMETIMES come back on its own with a really strong signal, but rarely.
I just rooted tonight so I have no idea if it's worse or not, but I'll find out tomorrow, eh?
I've also had difficulty with Bluetooth automatically connecting, but I have a new stereo so I don't know where the issue lies.

Nope. Didn't touch the xml file, as my 4G was connecting, and the fix was for 4G just scanning.
I still think we can tweak the WIMAX settings and make it come back faster.

Well at least its faster than toggling the 4G radio - just find a friend with a mobile phone so you don't waste any minutes.

Just dial your own number which takes you to voice mail and shouldn't waste minutes. I'll probably put a direct dial shortcut on my home screen until a solution comes along. Not that I'm worried about wasting my regular minutes....I used 29 of 450 on my last bill!
I can now confirm that moving/deleting the xml file does nothing for our problem. At least not on my EVO.
So, I've been looking at the WIMAX settings (using ##DATA# and my MSL).
There are some settings that look like they could be effecting this problem. Be forewarned, however, that some of the values preset are not considered "valid" when you make a change (leading me to add credence to my theory that HTC/Sprint goofed), so I'm hoping a nandroid backup will recover them. Open each parameter and deleting the values, gives you a popup of the valid values and units.
Here is what I tried so far:
wimax_idle_sleep(s) changed from 10 to 300 seconds - effect: little to none.
wimax_scan_attempt_timeout(s) changed from 1 to 20 seconds - effect: little to none. (note only 5-300 are valid values after this change).
Other parameters that look interesting and their default values:
Wimax_scan_retry(s): 300 Seconds
Wimax_entry_delays(s): 300 seconds
wimax_exit_delay(s): 2 seconds
idle_mode_timer: 60 seconds
Standby Time: 10 Minutes
handoff Threshold: 6
Anyone willing to mess with these (at the risk of losing Wimax, of course)?
That is one place I'm not going to mess around. I saw a stern warning about that recently on the dev forum.

[Q] No 3G Evo.. please help

hello forum..i been having a problem getting 3G on my evo i dont know what else to do i been looking online for fixes and no success so far (obviously) sometimes i get 3G for a few minutes other times it shows 3G but its greyed out but most of the time theres just no service at all...i am in a 3G area i can connect to 4G but very little (not really in my area) and i connect to wifi...im rooted but im on the stock sense rom till i figure this out..i called sprint and did a few resets but it didnt last after i hung up (of course) ...please help..any information would be appreciated
p.s. let me know if you need anymore info
Well, are you in an area where Sprint's 3g network is overloaded [therefore slow]?
The switches at the towers are set to send phones to 1x [to reduce the load] in times where it's necessary.
That sounds like it's what's happening to you.
Especially since you sometimes get 3g.
i wish it was but the other evos in this house have full 3g -__- im hoping perhaps theres a way to refresh or restart my 3g if thats even possible?
I don't how much help this would be but if you call Sprint they can send refresh signals to your phone. Maybe try that? Edit: Not sure if these are the resets your talking about.

You can turn the radio off and on via settings > wireless & networks > mobile networks > data enabled
It's important to note that, just because other phones are getting 3g and you're only sometimes getting it, it could still be the switches at the tower.
You can try updating your radio to the newest version.
http://forum.xda-developers.com/showthread.php?t=715485
Or wiping and reflashing/ruu your rom/kernel.
Sprint could also completely reset your line [on their end] and cause the phone to re-provision.

Now you have to restart the phone and it will go to a screen and you have to sit and wait for it to finish.

[Q] Complete Connection Drops w/ Full Signal

Ok, this is driving me nuts. Maybe someone has some additional ideas on what I could try out.
First of all, I am on Verizon in the SE Michigan area. At work I hover around 2-3bars 4G/full bars 3G. The same thing at my home. I am rooted and w/ 4.0.4.
I have tried the 4.0.4 radios, the hybrid 2 and hybrid 3 radios. For all of them I get similar behavior.
I would say almost half of the time when I request data (try to open a website, etc...) or if I try to place a call I get a total connection drop even though a stable connection (either 3g or 4g) is indicated. Call won't complete and/or data won't work - no bars and a little gray x. This is when I have a completely fine connection, it just seems to crap out when I request either data or a call. After about 30 seconds or so the connections automatically resets itself and it appears to be fine. Occasionally i need to restart my phone.
I've been getting this with 4.0.3 non rooted and 4.0.4 rooted with all the above radios. it's a massive pain in the ass. I had no such issues with my DInc and my gf has no such issues with her Razr.
Any ideas?
I would say you have bad signal, despite what your signal bars may show. No amount of data drops will stop a call from being completed unless it is a complete loss of signal.
The other possibility is something is causing the ril to crash. However without you supplying a logcat, there is no way to be sure.
So, do you think this may be a hardware problem? I am getting "no connection" when I try to make calls in areas where no one else appears to be having issues. Do I need to throw my phone against a wall and use my insurance for a new one?
Ok, ill run logcat and post when it happens again.
Sorry for borrowing your thread, but I also seem to face signal drops and don't know if it's because of carrier breakdowns or something else. I have the XXLA2 radio and run the latest AOKP.
My logcat is attached, if anyone wants to help me.

I haven't tried 4.0.2. I could try that, but i'm confident it will happen with those as well. The symptoms described in that report mirror exactly what happens with mine.
I did three speedtests with my phone, on the third one I lost data and voice. Tried to make a call and got a "Mobile network not available". Almost like something is completely crashing voice/data.

A closer inspection has led me to believe that I do not have this error on the ROM I use, so I'm sorry for possibly wasting your time.
Thanks for the RIL crash suggestion adrynalyne, I requested a replacement phone as it appears that is the only fix.

Data "stalling"

I don't really know to describe this problem better. I'm running CM10 (lately AOKP's latest build) with default kernels. I've flashed all the radios and tried a bunch of them in solid LTE coverage, I seem to have the same problem every time, which is the data seems to "stall."
It will show full signal, and then if i click a link, it will sort of just sit there, not really doing anything. Eventually it may load, or i give up in patience. Any one have any ideas?

I am using at&t stock rom and not yet rooted. Even I have the same problem. Tried to disable and enable data from the notification but did not help. But, when I turn on the wifi, and turn off the wifi again, it works fine. When wifi is turned on phone disables the data and try's to connect to wifi or shows the available networks, but I don't connect and I turn off the wifi, phone reconnects to the at&t data again and then it works fine. Not sure why.

But, when I turn on the wifi, and turn off the wifi again, it works fine. When wifi is turned on phone disables the data and try's to connect to wifi or shows the available networks, but I don't connect and I turn off the wifi, phone reconnects to the at&t data again and then it works fine. Not sure why.

I can't even run a speed test because it just sits there. Web pages "load" but wind up stalling. Sometimes they finish, sometimes they don't. I have no idea what's causing it. What modem are you on?

May be a good time to contact your cell phone provider for a replacement.
I was on a cross country road trip running CM9 on my GS3 and I kept running into the same thing. A temporary fix was to reboot the phone. Since I got back, I flashed SlimBean and I haven't seen the issue again.
In my case, I think its the SIM card. I used Google Maps/Navagation on my HTC G2 (using a micro SIM adapter) and my phone got HOT, I mean burn your fingers hot (upwards of 57 degC to 60 degC).
If it happens again I'm going to bring my SIM card back to ATT and have them replace it. I did some googleing and it seems like this is common with the Verizon variants of the GS3.

That's the next step... it means reflashing, and waiting for samsung to fix it though, which sucks a lot.
ive had this same problem and it would piss me off! i found out that busybox was the culprit. i uninstalled busybox and cleard my cache in recovery and all was well once again. if any of yall have busybox installed you may look into my solution.
I recently been having this issue also. But mine is a little bit different. Like my phone will say I am connected to "H" for data but when I load a Page it slightly lags switches to H+ and boom Internet works. When I stall for more then 5 minutes it switches back. I'm not sure if it's some battery conserving feature or what but I have no problem against at.
