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 currently have two HTC M8's that i have activated on AT&T. They have worked flawlessly for a long time, but I do have one current lingering issue on both devices. As of now, I am unable to access most google services that run off of the google.com domain, but only when i am connected to LTE. This includes most acount syncing capabilities, using the play store, using google search, or even just accessing google.com in a browser. All the while i still retain full access to any other site/services. All of this functionality works just fine on HSPA+ and wifi. Also to make it even more complex, It only seems to be an issue when the phone is using LTE band 17, when using LTE band 2 it works just fine. To add one more bit of oddity to the situation, a tracert from the phone to google.com goes through just fine with a low ping.
Things i have done to remedy the situation/rule out a carrier issue:
New sim card.
My sim card will access the play store just fine on another AT&T phone.
Used a VPN for a different route.
Factory reset through recovery menu.
Tracert to google.com, play.google.com works fine.
Edit1: Just thought to try something else. Set up wireless hotspot on my phone and connected my laptop. All google websites work just fine through there and tracert shows same results.
Sent in a ticket to HTC about it and they said they forwarded it to their engineers and i should be getting a call in a week with "something".
Im kind of at a loss and im open to any suggestions or ideas.
Hey guys am i the only one having issues with wifi, its so painfully slow takes forever to load a webpage forget about watching a video, and no its not my wifi because i have tried several different ones and its always the same slow speeds, ive gone over my data limit twice since i got the g4 because cant you wifi.
is their a fix for this iissue, love my g4 but seriously thinking about another device

Try the DNSet application - I had painful Comcast WiFi speeds, or lack thereof, and running this application before turning on WiFi solves the issue. Not sure if it's just me, but you should know that MMS doesn't work when the DNSet application is running.
What is stopping us from hardcoding DNS entries in the WLAN config now that we have root? Is this possible?

I looked at it, but the app needs to create a VPN to work, which is a whole other can of worms.
Do you have Comcast? I've learned that Comcast rolled out IPv6 out of nowhere, and many of its routers have issues with some phones (my gf's iphone included). I rooted my phone, disabled IPv6, and now I'm back to consistent 50-80Mbps download speeds on my phone.
Before, I would open up the Speedtest.net app, it would take a full minute or more to locate a server, and then the needle for the download speeds would constantly bounce between 0 and 50, sometimes with my phone prompting me that I lost my internet connection, asking if I would like to switch to data. Worth a shot! If you can't root, DNSet does this for you through the VPN, or you might be able to find a way to shut it off on your router.
I don't seem to have any issues with my phone picking up IPv6 over data or a few other routers, though, so I think this issue is more due to some bad firmware on certain modems.
Yes i do have comcast, their is many other cellphones in my house galaxy s5 ,s6, lg g3, iphone 6, none of them have problems but mine, how do i disable IPv6 once i have root

From the G3 after the 5.0 update, the fix was to disable IPv6 as well. This isn't related to IPv6 though, as it only seems to effect the G3/G4. Also, Google "What is my IP" when on mobile data and you will likely have an IPv6 address from Verizon.
I don't know that it isn't related to ipv6; Samsung phones have similar issues and my girlfriend's iphone does as well. I don't think the problem is the protocol itself, but how certain modems (seemingly Comcast ones) incorrectly implement them in their firmware
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

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"

Hope you sort it out sir, I normally don't get unlocked on ATT due to losing WiFi calling but I get a better signal now and you can just call to get visual voicemail fixed if yours doesn't work right away so I'm loving it....
I'm sure you'll love it too once you get it sorted...
Bringing back zombie thread.
Was a fix found?
My 20+ is having problems with wifi slowing to a crawl after just a few minutes.
Just bought a new router TP-Link AX11000 and it started so I thought it was the router but everything else on wifi in the house gets expected speeds my two 20+'s not so. I think it has to do with WIFI 6. If I stay within 10ft of the router everything is fine after that... I go in my bedroom 30ft away and have -63dbm signal strength and I can run a speed test and get 500mbps down try again and it will start at 500 and slow to around 45 try a 3rd time and and I barely get 4mbps 4th time and it's 0 with signal strength still at -63 on all of the test in the bedroom my upload will be 45mbps.
after a lot of testing with battery settings and things on the phone found out that my slow wifi was due to 2 settings on the router.
first in your router disable WMM, this made my s20+ use like 30mbps max in my case. now list my wifi 5ghz as +800mbps
seconds, disable ipv6 on the router. this made my phone ultra slow to everything. like play store hang on app updates, google drive take forever to load every single photo, like is taking forever to get the first reply from the server.
with that changed now the phone works at full speed on wifi. play store updates are shocking fast.
so lame that a flagship that cost nearly 1 thousand dollars have to disable things externally to work properly. no other phone or device works bad with the previous config of WMM or IPv6. I have a Linksys WRT1900ACS.
Hope they fix it with a software upgrade.
