yesterday the internet connection on my phone seemed to have stopped working. While the phone shows that it is connected to tmobile 3g, whenever i try to access anything requiring data (twitter, opera, etc) i simply get whichever error is associated with that program saying it cannot connect. I have tried several different radios and still get the same errors. however, everything seems to work over wifi.
I was using NRG's maxsense from june 12 when this problem started yesterday, have flashed to the june 26 cookie ROM from NRG and the problem persists.
I have also tried a few different apn's for tmous as well as turning off 3g.
using only EDGE seems to alleviate this issue.
any help would be appreciated.
does restarting the 3g connection work at all? this is a problem with at&t periodically, resetting usually but not always works. when it doesn't I call tech support and the very act of them looking at my account seems to fix the problem.
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.
Hi guys,
I`ve been using an HTC Desire the last couple of weeks and to avoid overloading my dataplan when I am at home I use my WiFi. It worke just fine `till today , when the phone connects as always but it cannot load any Internet pages or open any apps that use the Internet. If I switch to 3G it works just fine, when I go back to Wifi it stops working again.
The phone shows up on the DHCP Lease List in the Router Admin page. I can ping with no loss of data. I`m clueless to what might have happened.
Please help.
Thank you
Try changing channels on your router.
Remember seeing a post about this awhile back.

Not a problem. Just remember to help others when you can.
I'm having the same issue, WiFi connects fine but there's no data. Tried it all, different radios, changing WiFi channels on my router, different ROMs, etc. but nothing worked. Meanwhile an old Nokia E71 works like a charm with the same router... what can this be?
In your Wifi Advanced settings, you can select number of channels in Regulatory Domain. Also, check your WiFi sleep policy, and set it to Never.
Might help

Only other suggestion I can think is to change your RIL.
There is a thread here:

I use the latest (17) radio any the Nexus (1001G) RIL and have no issues.

This is the thing, just went to my office and it works fine with a router over there. It fails to work at home, where it DID work in the past as well. All other devices I have are working fine with my home router except for Desire... Any ideas?
CM7, RC3 Rom has this option.
Can't think of any other issue with a home Wifi setup.
I dunno if my problem is wifi related, but when using K-9 Mail, Yahoo and Gmail always returns unsent, with the "Message not sent, connection reset by peer" error always appearing. It wasn't like this before, and my wifi works okay with my laptop. Market on my phone works flawlessly too. Anyone got an idea of what might've gone wrong?

Tricky....
Logic - on the day the problem occurred, something changed on a) your router, b) your hanset. Did you do any updates, flashing etc. or were there any updates to your router ISP? New tariff or anything, maximum number of connections?

I did flash LeeDroid 3.03, coming from 3.02... then rolled back to 'fix' the issue but it persisted. I tried then flashing _most_ available radios, RILs and ROMs so I think it's router related. Now, why would this be the case if all other devices connect just fine to the same router? Does Desire have some issues with 802.11N routers?
I started using cm7 final the day after it released. Work great for the most part. I know the navigation is messed up a bit and see that it may be fixed in nightly 54 and it sounds like FB is having issues too, but that the board knows about that.
I have read some of the wifi issues but don't see any elaboration on what the problems are exactly. So for me. @ home I have no problem accessing wifi and connecting (WPA2). HOWEVER, at a couple other sites, one running a d-link 825 WPA2, it acts as though it is going to connect, the phone says it is getting an IP address, then it cycles and starts over to searching, found, getting IP. It jut keeps cycling. My home wifi is a d-link 655 and like I said no issues. Anyone know if there is a quick fix or is this a greater problem?
If you have an answer, great, if not I hope this helps someone.

changing the channel freq may help, the wifi issue thats spread through the forums is no matter what they cant connect to any wifi,and the fix for that is getting the Tiwlan.ini from cm 6.1.1 and pushing it to cm7 fixes wifi issue, but since you are able to connect to home wifi, and not others changing the freq channel to 11 or along those lines could fix your problem

I flashed nightly 54 and lost wifi again, as with all cm 7 releases. I pushed the cm 6.1.1 tiwlan.ini file and it still wouldn't work, so I connected to mobile network first, then I turned on wifi and it connected. This method might help you.
As for the issue I have with the cm 7 releases, I can usually connect to wifi, but I get no data moving in or out with wifi and no connection to google servers (wifi icon turning green from grey in status bar) so no internet on any app or browser or market, etc.

You need to install the nightly 45 or 54 since WiFi drivers were rebuilt. Also, check that your wireless router isn't doing any kind of special speed boosting to the g standard. Lastly, try forgetting your connection and re-establish it.

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?

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

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.

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"
