Data Connection issues?

I am wondering if anyone else has experienced issues with their phone taking way to long to establish a connection when surfing the internet. Some times when I click a link it will take for ever and sometimes not connect at all, of course when it does establish the link it is blazing fast. Typically when it cannot establish a connection I will just put my phone into Airplane mode and then turn Airplane mode off and typically after that it is able to establish a connection.
Thanks.

my phone often goes from good 4g reception to just showing two or three bars with no connection type (never auto switches to 3g, occasionally switches to 1x). just now it went from 4g to no connection type, so i dialed *#*#4636#*#* and tried turning the radio off and on, tried changing the radio mode to LTE only, cdma prl auto, and a couple of the other choices and it never seems to make a difference (always poor connectivity, sometimes total data drops, sometimes while tethering and sometimes when just using the phone normally). could just be LTE tower work in many areas, but im looking forward to an upcoming software/firmware update from htc or verizon.

Sometimes when I lose connection, I just restart my phone and everything works again. Try that and see if it helps!

I run into that quite often... sometimes it clears up after 20 seconds, others I have to disable and re-enable the data connection. I'm strictly in a 3G area, and it's done it with LTE on and off, as well as stock ROM and my custom ROM.

Really? A $500 phone and you're ok with having to turn it off and on to maintain a data connection?
I've had several HTC phones, going all the way back to my WinMo phone, and this Thunderbolt has to be the worst HTC phone I've used to date.
On my second device, if I keep it, it'll only be to grandfather the unlimited 4G data plan.
Inconsistent data connections and force closes up the wazoo... Wow!

Quickest way so far is use the free app called "Restart Connection" works for me like a charm....

Well, I've got the quick buttons in the dropdown tray in my ROM, so it's just as fast... still, its something that shouldn't be happening in the first place.

I never said I was okay with that, I just said it worked because I failed to mention doing that with success in my post

My dig wasn't at you, no offense meant buddy. I'm pretty much fed up with this device and will most likely return and cancel contract.
I've had issues with data since day one and I've never had so many force closes on one device.
This is Verizons flagship 4G device and it's a POS.
I've been on Android since G1, iterated thru the OS with each release thru to Gingerbread on my N1.
Verizon has a rocking 4G network, HTC released a crap phone that was delayed for several weeks. I would have thought that by the time they RTM'd it would have been fixed, or at least better than it is.

It's cool, I know what you mean but I'm liking the phone... Occasional reboots don't really bother me that much - this is probably because sprint wimax is nonexistent pretty much anywhere indoors and is the most unreliable network connection ever. the evo was a solid reliable device, but it was worthless because of the network and i canceled sprint to come to verizon for the thunderbolt. im happy with it despite a few annoyances. once i root and cm is released this phone/network combination will be untouchable.
i felt more comfortable using dialup and praying the phone wouldn't ring and disconnect me than i did using sprint wimax. their 3g is slower than dialup in a lot of areas at the moment, too.

This is driving me crazy also. My phone will constantly drop whatever connection it had (wifi, 3G or 4G) and just sit there with no data connection for a couple of minutes whereby I finally have to reset the radios and then wait while it cycles through 1X and then maybe 3G or 4G if I'm lucky. Or it just goes back to full cdma bars and no data connection. I don't have 5 minutes every time I want to check the internet or email to wait for the phone to reboot or reset radios or do whatever it's doing.
I had the EVO, and while the 4G wimax connection wasn't always stout, if you lost it you immediately grabbed a 3G connection that was solid. This delay/no data connection thing is making me think twice about switching to this phone. Love the 4G when it works, but it holds a connection way too infrequently for me to be useful, and I'm in LA where the service is supposed to be blanketed all the places I'm trying.

Wifi speeds decreasing after 5-10 mins?

I've noticed this since I got the phone the other day. I'm connected to wifi and for the first couple of minutes my wifi speeds are what they should be which are around 15-18mbps. Then after about 5 or 6 minutes maybe a little more the download speeds decrease to around .80mbps. Upload speeds remain the same.
Can others test this out.
Connect to wifi
Then run a speedtest via the speedtest app which is available in the market
Then put your phone down for several minutes
Then run another test and see what you get
Doesn't always happen right away but more frequently when the wifi connection is being used. HTC definitely has some bugs with the Sensation. Hopefully they'll be addressed sooner rather than later.
Using T-Mobile USA by the way.

Did you already try this fix? http://forum.xda-developers.com/showthread.php?t=1118017
I haven't had the problem you speak of.

Yup, problem still there. I called T-Mobile and they said they are working on an update to address the latency/radio issues. Hopefully that will resolve it.

Have the problem. I think either an.app we have installed is doing it or we have to wait on a fix.

Mine can't even hang on to wifi for that long, lol
Thank god I don't use wifi much.

I'm in this boat as well. After a while my wifi slows down greatly, restarting the wifi connection being the only method of restoring it to it's proper bandwidth.
On the note of the Slow data latency fix, I'm pretty sure that that menu in its entirety, as well as the ciphering option, only apply to the network data connection, and not wifi.
Edit: Addendum:
It seems to me to be correlated loosely with wifi-calling use.
It certainly isn't instant, but I've been testing it off and on and it seems that if I turn wifi calling off and then restart my wifi the gradual slowdown doesn't occur, but if I turn wifi calling on, then it does.

I heard unchecking the using mobile data speeds up wifi as well. And are you guys using the best wifi performance option as well?

Maybe its a certain app you guys are using. Mine stays at a constant 30mb/s down and 10mb/s up whether I'm on WIFI for 10 minutes or 10 hours.

I disabled WiFi calling and the problem seems to have been stopped. So far so good. It was dropping to 2Mbs and after disabling WiFi calling my speeds jumped back up to 17Mbs.

I talked with T-Mobile tech support about it, and since my phone was recently purchased they gave me another Sensation. The issue is no longer present, all the same apps, all the same settings, same network.

Lots of failed txt on LTE (SF)

Seems like once SF got lit up with LTE i been getting a lot of failed txt and double txt msgs. Even though it fails it seems like they are recieving them as well. This is getting really annoying. Anyone else getting this?

I'm seeing this as well.

Call the 800 # Att&t and make sure you are "provisioned" on the right plan.. this happened to me about a month ago....Don't bother with the fools at the store.. call the 800 number instead.. Hope it helps..

what exactly is "provisioned" ? seems like it was working fine before lte

Anyone find a fix yet? AT&T wants me to switch out simcard and possibly even the phone, rather not since i dont think its the issue, but its the only options to a solution they are giving me

Do any of you guys have an active Microcell in your place? If so then that is most likely the problem. Check out the ATT website, because it is a known issue that usually ends up with router issues.

I'm having this problem in Ohio, non-LTE area. Just started this week. A lot of messages seem to be going through when 'failed'

I am having the same issues in the bay area. My lte sometimes shows up and sometimes it doesn't. Recently I have had no data connection at al,. cannot connect to market or pandora. I have had to restart my phone a lot of times. Hope they find a issue to fix this..

I see this in DFW
Usually when trying to text and coming off wifi. I have seen several double incoming texts. I usually just long press the message bubble that failed and hit resend and it goes right through.

Huh, I haven't had this happen yet, but I'm not using stock rom.

[Q] Connection probs?

I just did the OTA update. Worked fine and sustained root. Brought my phone back to the way I like it and then, it said my phone was not connected. Just on WiFi. the 4G was gone(even though we don't have 4G here(Iowa)). So from like 11:30PM - 12:30AM I was without service. Anyone else too? Want to make sure it isn't a problem with the OS or whatever.
PS: Verizon is all over Des Moines, IA with LTE... AT&T 3G and EDGE in Des Moines... Stupid Stupid Stupid!! (this was a rant)

Hspa + is in design Moines too

same here
It is the same here. Working fine before update. After the recent update, problems with cell signal started all around. The phone works fine if it is static, as it keeps connected to the same cell. But once the movement starts and the phone needs to jump to a different cell, it loses signal.
Doing some research with the "network" app, seems like the phone is no seeing neighbor cells.

No issues after I updated (and sustained root).
And I have 4g just about everywhere here in Atlanta

You're right... I browse and text more than I call but it's still noticeable...
However I have had 1 bar of service for the past couple days, now that I'm home I'll see if it still happens.

No issues here either, and I have been travelling 800 miles by car each week this year for work. I don't ever lose signal...I lose data connectivity sometimes when I go in and out of roaming areas, but that has happened on every Android, CDMA or GSM, that I have ever owned.

I'm on 2.3.5 and sometimes cell signal is dissapear after some period (3-4 hours on connection).
I doubt to update it to 2.3.6 that it will makes my cell signals even worse.
Could someone enlighten me about update?
Thx

data issues

My gf's tb has been getting terrible data service since accepting the ota a few weeks ago. Her phone is rooted but runs a stock rom. Anyone else having this issue?

If you are s off and the radio from the previous version was better you could flash the radios from it and see if that helps.

I've been having problems for the last week or so. I'm dropping my connection a lot and even when I'm showing a steady 4G signal, things are moving a lot slower than I'm used to. I've seen people with other Verizon phones complaining too so I'm not sure it has anything to do with the recent update.

I was having issues like that the other day. I had to put my phone in airplane mode and take it back out just to get my phone to load webpages. The next day everything was fine again.

Same problem. I'll be fine for a while then I'll lose data connection completely, get it back, drop a few seconds later and this keeps going on for a while. For me, Google Maps has been something that drops my data connection after I launch. I eventually have to put airplane mode on/off for the connection to stabilize.

I've noticed these issues more frequently lately with various users in this forum. I myself have noticed data issues as well. Could it be a Verizon issue? If so many of us are having similar issues. I'm running eternity r248, great Rom but occasionally have these data drops. I'm in a good 4G coverage area.

I'm running Thundershed 1.6 and the most recent leaked radios. As far as I can tell there is an issue on Verizons end. For the past 4 days I've had a strong connection to a 4G tower but data doesn't work at all until i switch to 3G.
While troubleshooting this I flashed a new ROM, radios, kernels, hard/soft resets, battery pulls, reseat SIM card, everything. Nothing seemed to work so I'm convinced we just have to wait for Verizon to fix things.

Since about a week ago my LTE data has been frequently dropping in and out in previously known good areas and it will not transition to 3G. Fed up I decided to go into ##778# and change eHRPD to EVDO. Has been stable so far but more time will tell.
Update: It's still dropping in and out. Trying OpenMobile leak radio since I had good experience with it in the past.

There's ongoing data issues on Verizon's end, particularly on and near the east coast. Apparently, they're trying some different authentication settings that are resulting in mobile data automatically unchecking itself in settings, data drops, weak signal, and inconsistent signal. Hopefully Verizon will get it together soon.

I reported my issues to tech support the other day and finally managed to get it bumped up to the next level today.
The tech knew nothing about any network problems and when he did a search for customers filing similar complaints in my area (Metro-Detroit), he found nothing unusual that would lead him to believe that there was a widespread issue.
He is convinced that there's either a problem with my sim card or the phones radio. He mentioned that they have been having a lot of problems with sim cards failing and said that in his experiences, they have a life expectancy of around 6 months before they start acting up.
He is sending me a new sim card and replacement phone via Fed Ex so that I can test out both of his theories.

I called yesterday to talk about my data issues and the tech is sending me another bolt and Sim card with no questions asked

My replacement phone arrived so I popped in my SIM and fired it up. Same exact problems with data drops.
Still waiting for the SIM to show up, it was shipped separately.

Interesting... Sounds like a bad SIM but that seems strange to me.

I'd like to think that it's as simple as replacing the SIM card but I have a feeling it's a network thing.

most likely is. Been fighting with data issues for three weeks. 4g is completely useless lately because of the connection problems. And since they dropped a bunch of 3g towers around here, 3g signal just sucks. Lucky to be able to open a web page a couple times a day downtown in my city.

Sadly, I was right. Swapped out SIM cards today and within minutes, was having the same problems.
What's most annoying is that this appears to only be an isolated problem in certain areas and with certain users. If it was widespread, Verizon would certainly know about it and be on top of things. I'm not even sure that anybody at any level knows that some of us are having these problems with data drops.

Disregard. It appears to be network issue all along.

I have the same horrible data dropping issue all the time. I live in Minnesota, if that helps. I bought this phone used on ebay and I don't think Verizon will send me a replacement, right?

I recently had data drops with the latest radio. When I switched to the 605.9 radios that stopped. That may not work for everyone though.
