I'm having trouble getting wifi tether to work with 4G. It was working fine yesterday, and nothing has changed between when I last used it and now. The weird part is, when connected to 4G and tethered I can go to any Google site, but nothing else will load. When I'm connected to 3G everything works. I thought maybe it was that wifi tether is set to use Google's DNS and perhaps Google was having issues, but why would they work for 3G and not 4G. Do you think Sprint/Clearwire is blocking Google's DNS in an effort to curb unpayed tethering on 4G? Any other ideas?
Edit: I've tried a few different free DNS services and the same thing happens with all of them. No connection issues on 3G, but ONLY Google pages will load via 4G, regardless of which DNS service I'm using. This is a very strange problem....The only two things I can think of is Spring/Clearwire blocking DNS services or there's some sort of bug on the 4G network at the moment.
I'm seeing the same issue, and I did the same troubleshooting steps. It's almost as if they are inspecting http headers and checking the MAC against some database. Hopefully something is just broke on Sprint's side, though.
Co-signing. 3G wireless tether works while 4G doesn't.
Same Problem in NYC
Hey Guys, glad I found this post. Thought I was going crazy. Everything is fine on 3G but only google sites and certain non picture portions of other websites will load on 4G.
Strange thing is that all websites are fine on the phone itself while on 4G.
Heard someone that's using the paid sprint hotspot is having the same issue, so I'll keep my fingers crossed that this is a temporary issue.

What? You do realize that the only MAC Sprint ever sees is that of the phone, right? As for inspecting headers, not only would that be trivial to get around, but it would also be likely to cause breakage in third-party browsers as the whitelist would likely not be complete. Reliable browser detection via HTTP is near impossible. That also would have no effect on non-HTTP traffic, IMAP e-mail or an XMPP instant message connection for example.

I believe there is an individual MAC for every radio in the phone, so you would have a unique MAC for your cell radio, wimax radio, bluetooth radio, etc. Also, I don't believe he's referring to the browser's identity info, but the packet headers that contain DNS/tcp/etc. info that all network services use. That would have an effect on ALL traffic, and it clearly does as nothing works expcept most google services.
I have been usb tethering with CM7 since GB6 and it would switch back and forth between 3G and 4G without any problems. Pre GB roms would require google tether which would only work on 4G.
I am now experiencing the same dead 4G tether and am not droping back to 3G since the 4G signal is good. Yep like everybody else the phone by itself is connecting and browsing.
All tether traceroutes and pings seemed reasonable. Flashed back to an earlier working release and it also failed. I have not tried any port other than 80 at this time.

I just added the Sprint HotSpot to my account and I can confirm that it's working flawlessly with 4G. Even with the HotSpot feature on the account, wireless tether will not work.
Imap works, SMTP works, ftp works, ftp via browser (port??) or any other browser activities do not work while tethering on 4G.
Port 80 and/or tethering via browser is hosed.
What wifitether version is everyone using? I'm using 2.0.5
Well, I got home connected to 4G and tethered to my laptop. Everything worked. Might be dependant on what tower you're connected to. I'm using wifi tether 3.0 pre11, but had the issue with 2.0.7.

I believe you're correct. I downloaded 3.0 pre11 and still nothing. Strangely enough it would allow streaming of an Amazon video on the browser but it worked on 2.0.5 as well. I wonder what clearwire is doing on their end. Does anybody have any ideas on circumventing it?

I didn't go into much detail since I was posting from my phone, but allow me to expound now. Wifi-tether does nothing more than NAT your internal network to it's live IP address, whether that be on 4G or 3G. Both of these radios have the physical addresses that would not be hard to trace on a cellular network. When the packets are transmitted, as is the case with any packet transmission, the only information that gets changed as the packet passes through the NAT is the IP address. All of the other information stays the same. Now, in terms of most traffic, this isn't a big deal, but with HTTP and HTTPS traffic, the stream of data sent contains the header of the browser sending the request. Since the NAT doesn't mask this data, it's sent out into the wild blue yonder (Sprint's Clearwire WAN) where the capability of inspecting the packet header is very easy to do with most enterprise grade equipment. Now, while any blacklist of headers will inevitably be incomplete, a very simple whitelist of 'known' headers - such as mobile browsers on the market and the included browser on the phone - can be implemented with a few short lines of code. Now, while it might seem trivial, how many users are going to attempt to obfuscate or change their packet header identifiers just to get online? They'll give up, use another connection, or just view the pages on the phone.
I tested this for awhile today, using multiple different browsers on my PC and got nothing. I opened up a VPN connection to my workplace, and routed all my traffic through that (that is, encrypted in an IPSEC tunnel) and the internet worked fine. The most brilliant part, from Sprints point of view, is that the HTTP session is never actually 'closed', just kept in a perpetual waiting state where no data is transmitted. If this is all a fluke, it's the best bandwidth saving fluke Sprint could ever dream up.
All in all, I'm really really hoping this is a snafu, but all signs are pointing to sprint catching onto our usage, which is a huge uh-oh.
edit: I was still able to ssh and telnet via my tether, and open up the VPN and receive email, which points to this being a targeted attack on HTTP. Double uh-oh.
Firefox, IE, Opera, Epithany, Chromium, Midori and Konqueror all fail.
Port 80 traceroute is good.
Does anybody knnow of an agent switcher that can be used?
What about downloading Adfree and installing the host files. That fixed my data issues on my Evo.

This appears to be a new sprint development. Are you saying that you can tether with 4G?
Aha... finally found some people who are having the same issues, 4g just stopped working with wireless tether about 3 days ago. 3g works just fine, and 4g connects and is pushing data to the phone, but no webpages are loading on my laptop when 4g is on... I'm out of 4g range right now, but will check back in when I'm back in range tomorrow.
It's working for me again. I'm replying to this thread using my wifitether uder 4G.
Working again here too.
I'm experiencing a very odd issue with my Galaxy S3 on the Virgin Network. For some reason I can't go on any SSL enabled site no matter what browser I use and which website I go to. The most descriptive error message comes from firefox which says SSL received a record which exceeded the maximum permissible length. Oddly if I enable wifi or otherwise bypass the regular network (VPN etc.) everything works properly. SSL enabled apps like banking sites work with no issue.
I'm currently on the latest nightly of the Carbon Rom, though I've experienced it when I was on Cyanogenmod as well so I don't believe that it has anything to do with the rom itself. Any idea on what might be going on?
Ensure your APN settings are correct.

Is your time and date set to automatic?
My APN settings are correct and my time and date are set to automatic.
After doing some more testing only certain SSL sites don't work which makes the whole situation even more murky. startpage.com doesn't work, but the login of tdcanadatrust does. This is really weird.
Are you in a public WiFi network or in an area with a lot of WiFi networks?
If in public WiFi: Someone may be trying to hack you by SSL strip or redirect you.( Which can be why a VPN works)
If there are many WiFi networks in range : Download WiFi Analyzer from Google play to check WiFi channels, and switch your WiFi router to a cleaner channel if needed.
(If there are a lot of WiFi networks all on the same "channel", it can cause common data loss,lag and congestion. )
Sometimes a VPN can fix the problems with congested wifi channels, but I'm not sure.
If none of these ideas apply, clear cookies and cache.
If that still doesn't work:
Settings > Security > Clear Stored Credentials.
This will clear your SLL certificates and VPN info saved on your device. It might help with your browser.
While the SSL strip idea is a valid point that I hadn't considered initially I don't think that's the issue because I rarely connect to unknown wifi networks when traveling, and I think that all certificates would come back invalid if somoene was pulling that instead of the hit and miss situation I'm currently experiencing.
The Wifi bit is what really gets me though since the sites that don't work on the cell network work perfectly when I'm on wifi with no other changes needed other than the change in the way the phone connects. I have tried clearing the browser's cache with no luck and I'm not able to clear the stored credentials as described as the option is greyed out for me.
I thought that it might have something to do with the cerficates themselves, something about the way the browser/phone accepts certs depending on connection method but I can't see any difference between working sites and non working sites other than a difference in certifying authority (GoDaddy vs Verisign for example)
Problem Solved
I'm bumping up this thread to bring attention to the fact that I've found the solution to the problem. The issue is not with the rom itself, but the proxy that Bell/Virgin insists on its users using. Clearing the proxy and port settings for the Bell APN found under mobile device settings fixes the issue nicely. Special thanks to Dream_Team over at this thread for finding the solution.
Makes me wonder why there's an HTTP only (port 80) proxy set by default in the APN settings when it's not needed to access the network..
I would like to invite everyone to try if they have the same problem
For me, I have done a lot of testing, and I have found that, with any open WiFi hotspot (ones doesn't require wifi password to connect, with captive login or not), even G4 saved the network, half times it won't autoconnect.
When you go into wifi setting, the network is there, and there is an message below the nextwork saying:
"internet is unavailable, cannot autoconnect"
But if you tab it manually, it will connect and fine. I tested it with multiple hotspots and all have the same problem. I tried all different ways like delete the networks and re-add, nothing works.
Any of you have same problem please confirm below and let us know if you have found a solution, this is yet another ridiculous problem LG4 has and not fixing it, who are they to decide internet is available or not on a wifi hotspot?
my G4 is 812 10c
Any one encounter the same problem?
Yes I have this issue also. Don't know what would be causing the problem

Thanks for confirming,
Very annoying issue and I am surprised it hasn't be raised and discussed in here.
For me it is way worse than occasional touch issue
Any solutions will be appreciated

I can confirm I have the same issue with mine. Very annoying.
Thanks for confirming, again showing it's not an isolated instance.
Is this issue only for Hotspots? Or any Wifi device? I ask, because I don't see a problem with my WiFi router at home.

For me it is only for open Wi-FI (no password required to connect), the tend to be public hotspots.

That underlined bit is interesting.
so it seems this only occurs with open networks ie ones that don't require a userid/pass.
otherwise you have no problems connecting when there required login is required and is saved already.
eg. your home wifi ?
some more reading led me to this post.
My G4 doesn't have any problem with the open network at my work. It connects automatically as soon as I drive in the parking lot, if I leave and come back, as soon as I'm in range it re-connects just fine.

Have we considered this might be done on purpose as a safety thing?
You shouldn't want your phone/laptop connecting to any OPEN network automatically that you haven't vetted. This is how scammers skim passwords, etc., by offering 'free' wifi hotspots in busy areas.

Not quite, it happens on open networks that I have connected to before i.e. saved and as you put it vetted.
Connecting to saved networks that are passkey protected works fine.
Yes that's right, for me the network that requires password has no problem to auto connect
And the post you linked for refresh DHCP, I tested and it doesn't solve the problem

Then there is no problem here is there ?
I also have this problem.
To clarify, my situation is for open wifi where the provider redirects you to a webpage where you click "ok" or "accept" to proceed.
The first time I connect, it's fine. But, when my phone tries to auto-connect the next day, it gives the error described. So, I have to manually open up wifi connections, view the list, select the wifi name, and connect.
So it works fine after some manual intervention, but there is a bug I think in how the G4 handles these types of open wifi connections, once they are saved in the phone's history and you try to connect again later. So there is a problem here, but it's somewhat nuanced and easy to miss.

Your description sums up the situation well.
Doing what you want could create a problem of another sort. read this.
http://android.stackexchange.com/questions/64380/stop-wifi-connecting-to-open-networks
No this is not the same.
i only want G4 to autoconnect to network I saved before, meaning the one i have used before and want to use it again.
The problem you are referring to is having android auto connect to random networks, which of course should not happen.
Also G4 currently does not connect to open wifi that doesnt require login either. Even it clear have good internet connection, it wont reconnect, which is clearly a bug

see this is where it gets tricky, that post was referring to networks set up by a telco around the city. the ssid is the same its not a random network. This is exactly what you want.
you accepted it when you were in location a, now you are at location b and want to connect. so it should connect automatically ie no different than if you were to return back to location a.
You said home wifi works, so leaving wifi on, walk out of range and then come back in range and it connects automatically. And you expect the same behaviour with an open wifi that you accepted prior.
Way i understood it is that guy is complaining about what you want with open wifi
Thanks for clarifying.
I went back to re-read the post you pointed out. OP of the thread wants to block all the open wifi hotspots with paywall. It is not because he/she used one paywall network work in location A and doesn't want to use it again in location B. OP never used the paywall network (because it charges) and doesn't want to ever connect to it again, in that case, delete it from the saved network list should solve the problem.
In fact, Op also wants to use non-paywall open wifi, which is same as what I want here with G4. We both have the same need, which is auto re-connect to known, used, and trusted network. Here is exactly G4 cannot do and clearly having a problem. As I said before, even for network that is open, no paywall, and no log in required, G4 simply cannot auto connect, and claim "internet is unavailable", which is false and need to be fixed. Furthermore, even if there is a captive login, G4 should not refuse to auto connect before informing user so. While LG clearly has no problem sending tons of notification for their bloated LG smart notices, right now there is no single notice about WiFi auto connect failure, you will only discover the problem after you open WiFI set up page.
I copied OP's own words from the other thread FYI
"here are random open wifi networks everywhere that allow my Android to connect to their network but won't give internet access because there is a paywall"
"There are a wide variety of providers like BTOpenZone. I'd like to block them all, adding exceptions if I ever find a non-paywall connection"

I'm having problems connecting to the open wifi at work. On my Nexus 4, I would get notification of the open wifi, click the notification, choose "use this network as is" and then open the web browser to accept the disclaimer. On the OP3 I click the notification and it gives me the sign in to network page (screenshot 1). From there I click "Continue Anyway Via Browser" which gives me a blank page or a load error page (screenshot 2 and screenshot 3). Any ideas on what the issue is?
Furthermore, after I perform the steps above, the wifi icon is there with an exclamation point and it also says LTE on the cell network which tells me that there is an issue with the wifi and the phone is using LTE for data?
Following-up on this again, when I sign-on to the public wifi via steps above, the wifi sign has an exclamation next to it and the data icon (LTE) is still there. Then if I disable mobile data and re-enable it, the LTE and exclamation point go away which tells me I'm then on the wifi. But why do I have to disable mobile data for this to happen?
I'd never use public WiFi. Never.
Yep absolute clean flash
Happens in every Oreo ROM except zui
Sign in to a WiFi network
Then it goes to connectivitycheck.gstatic.com
Then suddenly disappears and WiFi is connected then after sometime it gets disconnected I have to reconnect again and wait for the notification of sign into a WiFi network and click it again and above process continues
Hello,
I haven't faced any such issues with WiFi that I have used various Oreo ROMs and in present AEX 6.0
Could you please provide more information about the WiFi network you are using?
Like for me,
Home :- Router TP-Link/DLink/Tenda on 2.4 GHz. I simply search for network name from Wireless settings menu, put the password and I am singed it
Hotspot :- Same as above
Jio Net :- I have Jio net app installed with my credentials given. I simply search for public WiFi of Jio and app does the authentication for me.
Do you have any VPN configured?
Thanks.

Nothing like that my router is tenda 2.4 ghz
On bsnl WiFi
And it's not a notification of unlimited differential post certain usage top up plan or something kind of request notification its something else
Its not like I have to put my WiFi ssid and password again and again as it disconnects its more like I have described above
It's only shows sign in to this WiFi
Notification and after sometime connects automatically after pressing use this network
I haven't used BSNL in past couple of years but it seems this issue you are describing is due to BSNL connection and its plan limitations.
Earlier, last when I used BSNL, it used to give this landing or authentication page once the plan runs out of high speed allocated data and turns to more slower unlimited version. That authentication or landing page used to have a option to input to user authorisation for purchase of booster pack or continue as a slower but unlimited mode.
Try to switch to any other WiFi network to check. Even a hotspot from any other mobile would also give you an idea to understand the cause of this issue.
Thanks.
