Losing data connection on CM7

I have been keeping up with the updates hopeing each one will fix my problem but not yet. I don't see others with the issue.
I'm running the latest Test4(Test3) using Slayhers stock kernel. Everything works awesome except intermittently I lose connection whether I'm using Wifi or 3G(No 4G in my area). The only way I've found to get it back is reboot.
Is this a widespread issue or just me?

Same issue here. I live in 4G area. Intermintent Data Loss. If i switch to CDMA i get a 3G but CDMA/LTE i get nothing. I had data allday yesterday but none today.

I think the RIL is still being worked out. Bear in mind that this is a Pre Alpha Pre release. Also LTE is something completely new to the world of CM and to American cell phones. I've run CM on 3 different devices and I will tell you that by the time nightlies roll around, it will be near perfect. The CM team won't put their name behind something that is half working, half assed, etc. Be patient.

I had the same problem but now I have a small problem. I have a very fast wifi setup at home but it doesn't like to actually connect to it. Looks like 3G is riding shotgun for a while.

One thing I read about the WIFI is, try turning the WIFI on then reboot with the WIFI on to see if you then connect.

Yeah, I think we'll all be experiencing this until the crew addresses it in a future update. However, it is still a great start. Not a whole lot of major issues, no deal breakers. I'm still using it as my DD.

Definately!!! I love the cm7 build and I'm thankful for all the work. Just wasn't sure if there was an easy fix I had missed.
Thanks all!

Poor WIFI signal on sensation?

I have been using it for a couple days now. The signal is very weak on my phone, it disappears sometime. It shows "Excellent" on my laptop. Does anyone has this problem?
I'm using stock rom from tmobile.

Actually i have almost the double of wifi strength that i had on Galaxy s2, no problem at all, so test it better

Did you get the 2.3.4 update? It improves WiFi signal strength.

Mines great ! Way better than my old Evo 4g. Just picked up the NETGEAR N600 dual band wireless router. Works like a charm.

On my phone, " Upgrade version to 1.45.531.1 (45.18 MB)- FOTA update". Is this what you are talking about?

Do you know about the deathgrip issues with the Sensation? Try looking it up, it might be what's affecting your signal.

Laptops probably have better wireless antenas built in. It is after all a cellphone we are talking about. Just like your 2 core CPU is no match for a 2 core laptop/pc, same is probably true for WiFi. But that's just my guess. I don't get a lot of range on my sensation either, but my previous phones were kind of the same, maybe even weaker.

Same here !

Mine picks up the wifi from the back of the house just fine. If I turn the phone and put my hand on the top it gets worse for sure.
I dont use wifi tho so it doesn't matter at the moment. I hear the update improved this issue.

I used an iphone on the same spot. It got pretty good signal. I think that's the problem from the phone.

The wifi gets poor signal when you cover the top part of the back with your hand, like when you rotate it for landscape, it loses signal. Something I noticed whenever I'm on youtube

Try some of the new custom 2.3.4 ROMS. It completely fixed my deathgrip on my WifI. I don't like to name them but just look in the changelogs and you will find them,

Nope, when i am using WiFi its been good. Does this happen to you everywhere?

I just made the newest update. Yeah, I saw some new APs, but even I connected to one. It gets so easily disconnected. I think I will bring it to tmo store to check it out.

Question about wifi.
Hello guys, I have a question about the wifi.
I use cm10.1 and wifi on the phone is very weak (the same was with the factory-installed software)
Is there a way to strengthen the range of wifi?
Greeting.

poor signal wifi problem is here too!
if i am not wrong I think its an Hw issue cuz mine older galaxy gio gives me full range wifi and don't even drops.Sensation is dropping like hell!

There is a difference of wifi signal on CM JB roms VS ICS / Sense Roms. I tend to have a LOT better signal / performance with Sense roms.
And I'm not just talking about the signal strength bars, but speed, overal connectivity, stability, etc. Stock kicks ass, same goes to all ICS Sense roms (even ICS AOSP), but Jelly Bean roms I have signal degradation.

Potential WiFi issue?

I'm here writing on tapatalk and browsing and have noticed that all of a sudden the WiFi will go off, drop out and restart. I hadn't ticked the : best WiFi performance, which drains more battery, so I'm not sure if that has anything to do with it.
I also have he app: power manager and I'm not sure if there is an app doing that to the WiFi.
Anyone else had this issue?
Edit: definitely having this issue. Best performance or going manual on the WiFi Settings seems to have settled it. Hope HTC comes up with an update for it...
sent using HTC1S

I also tested the static rather than the automatic solution for the WiFi, and it tend to drop equally. Only way it doesn't drop seems to be if I use the: use best quality WiFi, which reduces the battery life tremendously!
By the way, this is not happening during te phone's sleep mode, but during normal operation.
sent using HTC1S

Not sure if it's related, but there are definite wifi issues with the one s. Mines completely stock, no power managers etc. It locks onto wifi points that that have always worked well for me (work, home etc.) with my desire and never disconnects. It seems in this mode it uses much more power and even gets a little warm. I can have left home for 4 hours and it still thinks it's connected and then has no data connection. The only solution seems to be to disable and enable wifi again. It doesn't seem to be able to roam from ap to ap without getting stuck on one of them

I think this may be an issue with Android 4.0. I have a Transformer Prime tablet running 4.0 and I get the same thing. WiFi drops out for a few seconds and quickly reconnects. I have noticed that it only happens in the first 12-24 hours after my tablet has been restarted though. After about a day running solid it doesn't happen.

I had a Nexus Running 4.2 and the wifi was great so probably not Android , more radi problem as discussed on other threads

I'm getting mine replaced tomorrow just to see if that will improve things. Unfortunately I was not able to make sure that the handset's serial number

Looks like first impressions that its stable but having said that,y sim card is still on the other handset. I don't know if that has anything to do with it...

Mine is opposite where I have no issues while using the phone, however, when phone goes into sleep mode, it loses wifi. Comes on auto when using phone again.

Exactly the same symptoms on mine (stock Orange UK). Hopefully we will get a fix soon, as its a pain.

Update.
The WiFi signal on this current phone seems to be spot on. No signal drop with any case on or covering the top of the phone. Signsl doesn't go to sleep along with the phone being on idle and overall really pleased.
I must also add that this new phone seems to have a remarkably better battery life as well. With my usuall use of web, tapatalk, a couple of photos a bit of WiFi, continuous account sync etc, on auto brightness, im at 13:20 and I have the phone on 83% battery when on the previous handset with the WiFi problem I was eating up the battery really fast. Usually I was at about 60% by now

I had exactly the same issue. Since I have changed the "option" / "wifi"/ "settings" / "extended" / "keep WLAN active in standby" = "never" (I don't know the correct terms in English), I haven't seen that problem anymore. I seems that the issue is standby-related, WLAN rescan won't start properly when waking up.
However, I don't think that this issue is related to the issue mentioned by the TO - it's the opposite.

I just noticed this issue when I left for work this morning. I have "Best Wi-Fi Performance" enabled, which was mentioned as a fix in previous posts, but it does not appear to be helping. When I leave for work and get into my office about 5 miles away it still shows as being connected to my home wifi network, when I try to use data like going to a webpage etc, it says "Data Connection Lost". Its like the phone doesnt know how to disconnect from a wifi network. I have the latest update to 1.84.531.2 710RD and still seems to have this issue. Have there been any updates from HTC or T-MO on this issue?

To follow up on this issue, I have called HTC and T-Mobile to find out if it is a known issue. They both told me that they were aware of the issue and that HTC is asking the carriers to report the issues customers are having back up to them. HTC said they are working on a software update that resolves the Wi-Fi disconnect issue. The T-Mobile rep said to have anyone else who is experiencing the issue to either call T-Mobile if they are your carrier so they can report the issue, or call HTC directly.

Been having this issue too. Called up T-Mobile and since I'm still within the 20 day window for return, they are sending me a new device. The girl that helped me didn't even want to talk about the issue or if it's been happening a lot. She didn't even ask if I had tried any trouble shooting. Just sent out new phone with free standard shipping. Works for me I guess, just hope it's hardware related, though I suspect it's software. We will see.

I did a factory reset on my phone and have been having much better luck with the WiFi issue. I think its definitely software related.

Not here. Factory reset was first thing I did (and always do) after applying the latest update.

I just noticed that on my phone as well. If I set it to beat performance the WiFi signal goes crazy. So I uncheck it and it works "normal"

I also disabled best wifi performance and have not noticed the issue since. I dont know if its because of the factory reset or because I have disabled best performance. I have also changed "keep wifi on during sleep" to never and that may have contributed to fixing the problem. I really have no way to tell, and now that it appears to be working correctly, I dont want to mess with it

Random reboots

I would try factory reset then take it back if it keeps doing it . One of the good things about a non removable battery is its suppose to help with random reboots. I've never had one so it might be something wrong with your phone.

I'd be sending it back. I'm on my second handset due to the chipping MAO issue. My first one must have rebooted about 3 times in the course of 5 days. My current one hasn't done it yet. Sounds like a fault somewhere.

Just had one reboot few mins ago, had the phone for more than two weeks, never experienced this before.
Only difference was I had installed Battery app with shows a number of remaining battery on top left corner on notification bar. Uninstalled it right away. Not sure if this app caused the reboot will report back.

My phone has rebooted several times and it always happens when a program hangs and I try to get out that program. It hasn't been specific to just one program. It's happened to me with Google Play, Play Market, chrome Browser...

My one-s did this a lot from new. Seems to have settled a bit - desperate to find out if it's a hardware issue or not as I need to return it in next day or 2 if so. Seems to be happening to too many people to be hardware unless something is majorly botched!

Is wifi on?
My router was acting up and my phone would reboot every time I tried to connect to it. Factory reset did nothing.
I reset the router and updated the firmware and all is good. It was a Dlink 614+ or something like that.

Yes, wifi on. My router is a 'draytek', a new model and up to date though. My desire running CM had no issues with it.
I have noted however that there appear to be other wifi issues with the oneS. It doesn't always disconnect from wifi even after leaving the building, eating up the power and leaving you with no data connection. I've had to put the wifi widget on the home screen to turn off and back on again to get it functional. It's a pain. Still pondering about returning this.

I have a stock HOS, and Yes I get an RR a few times a week, not 10 per day. This weekend it just went to a power off state for no reason, pressing and holding the button the first time just gave a short green line flash across the middle of the screen and it failed to boot, releasing and holding the power button a second time did boot the phone again.
I also have the same Wifi problems described by others, but worse it can not find my router (2wire 2700hgv) when the SSID is not broadcast and my neighbours SSID is! This is my only HTC or Android device with this problem.

HTC One S in the UK, stock everything, no root
I also encountered regular reboots (approximately hourly) during my first week of use. My theory is that in my case this may be related to the radio issue reported in other threads - that of the connection jumping rapidly between different connection modes.
Since WCDMA coverage in my area is terrible anyway, I switched the radio to "GSM only" under Mobile network settings > Network mode. In addition to fixing the connectivity issues I was experiencing, my device has not reset once in the weeks since.
Not ideal, but since I'm on wifi nearly all of the time, the slower speeds aren't an issue for me. I am hopeful that when HTC roll out a firmware fix for the radio, it may also put an end to the frequent resets I experienced using the "GSM / WCDMA auto" mode.

4 days old and no reboots
rooted--no custom roms yet
i too have the battery % icon and will see if i get any reboots now
any of you guys have the "tampered" in bootloader that shouldn't be there and getting the reboots

I've had two random reboots. The first while using chrome, the other one right after it had booted after the first reboot then I updated to latest firmware, and I haven't had any since that. Maybe that's what the update does ?
Sent from my HTC One S using XDA

I also had random reboots but took it back and got a brand new unit. Its rooted and running custom ROM. So far no reboot issues. Though when my first unit was rebooting it was after an app froze up and I back out of it. From testing other units it appears to be a RAM issue. Sense uses to much memory. Seems the restart occurs after dropping below 165 mb available RAM.

Take your phone back to to T-Mobile and have them replace it. I had the same problem with the one I bought my wife. It also had a problem with WiFi calling and they replaced it on the spot.

I have noticed that if I am streaming music with wifi and go to 4G, it tends to reboot. Either its plugged in to my car stereo and I drive away from work, or I have a set of bluetooth headphones paired with the device. In both cases, beats audio was turned on. But. I am used to random reboots with HTC phones.

Anybody still having data issues?

I've been using my Rogers HOX ever since it came out but always had random data drops. Tried all kinds of radios (with or without RIL) and all kinds of roms and the issue is still there. Losing data is not the biggest issue but it also drops the battery real quick because it keeps trying to connect.
Anybody ever find a solution to this?

I'm using the HOX on Straight Talk and lately I have noticed that when I have WiFi on for a while, assuming it stays connected, I lose mobile data. The only thing that bring it back is toggling airplane mode or rebooting the phone.
I am on Jellybean, and I am not sure if the issue was present in the stock ROM's.

Yep still having the same problem on AT&T with every combination of Kernel/ROM/Radio you can think of. I can also say that it isn't a "rooted only" problem because a coworker is having the same issues on 100% stock software. There's always that ONE THING that keeps my phone experiences from being perfect. Grrrrrrrr........

Stock 2.20 on Straight Talk. Have to toggle Airplane occasionally. Especially in North Little Rock. ::shrugs::

OP, have you restored your stock setup to see if the issue persists? Basic question, but for the sake of a starting point.

After so long, finaly found the problem. I don't know if it'll be the same for everyone but the problem was Swiftkey keyboard. The moment I uninstalled it, the problem did not reoccur.

I have the same problem and I can assure you its not the phone, I have used many android phones, iPhones, and regular phones on rogers 3G network and they all have the data drops in general like dropping to 1 bar and no service once and while.
You might want to switch your network to wcdma/gsm instead of wcdma/gsm/LTE. If you dont have the correct APN for the rogers lte network it will keep searching for the lte nrtwork causing the data drop. As soon as I turned my lte toggle off the network stopped dropping randomly though I still get those random data drops caused by the network

We had this issue with the rezound, it actually occurred because you flashed different radios.
You had to flash a ruu or a modified one without the system image. See my SIG
So try flashing a ruu, this doesn't explain someone with a stock phone having issues but I bet that's just tower issues
I don't have any of these issues

Tried all of the listed solutions and nothing worked. I know it's not the network because I don't have the problem with my Note II. Swiftkey was the issue for me, once removed, the issue never reoccurred.

Wow, you might be onto something here. I just installed SwiftKey last night and immediately started having issues. Data has been off-and-on with different versions of different ROMs, and never suspected that my issues may lie within an app that I was using. I was mucking about with radio ROMs and a million other settings, never realizing that SwiftKey was installed right around the time I started having issues on each ROM.
I'm going to jump back to CM10 this evening and see if this was my issue.
THANK YOU in advance! (Thanks button has been hit!) Nice work!

You gotta be sh***ing me! After all this time scouring xda and numerous other sites.starting my own tread it was SwiftKey all along? Wtf? I did a thousand different things. Nothing worked, took off Swiftkey, bam, flawless. I've got a T-mobile GS3 incase anyway was wondering, no, apparently it's not just with htc or AT&T/Rodgers. Weird though cuz my wife has a AT&T GS3 with Swiftkey and has no issues whatsoever... Did you dl your version from the playstore or from a 3rd party? Thanks a million for posting your solution. This was absolutely killing me. God do I hate this stock keyboard though...
