Cant take the WIFI issue anymore as I think its Hardware

The design is to blame for the wifi issue. IMO the G2x rebooting problem is less severe than this. I use wifi 90% of the time and ive had 3 units which all had this issue.
The others that dont, I dont know how you got lucky, or if you got a bad ass N router and thats the trick, but I cant take it. I cant even play a online FPS game in my room without losing signal. Anyone want to prove me wrong in that there are a few good ones? and if so please post a video?

Death grip here also. I guess I'll just have to live with it.
However, there is one good thing. HTC can release a cover with a design that won't have the issue (they won't, but I hope there will be some 3rd party ones)

"Deathgrip"? WTF is that. the iPhone disgusts me, thanks for this.. now it's running rampant all over the internet even when it doesn't make sense.
There is obviously a problem with the WiFi signal strength and yes it's a design/hardware issue. Exchanging the phone won't fix the problem.
I solved it by moving up a WiFi router in my room that repeats the WiFi signal from my main router. I had the secondary router already running DD-WRT software which is required for this type of thing.

Why didn't you just continue your other thread? 2 about the same thing is a bit much

No deathgrip here, I've tried and tried. Dunno what to say Brah. Works the same with my N router and my G router, Perfectly.

It's got to be ground issue.

yeah. i have been with mine for 2 weeks and since about just a couple of hours ago the wifi wont work. it was working fine all day then i was going to check fb and it said that there was no connection. it clearly had full signal. i restarted the phone and worked well. then later i was going to access the camera app directly from the lock screen and it froze, it wont do anything. pulled the battery and turned on the phone. after turning on the phone i turned on the wifi and it will not connect. it detects the signals and tells you all the info about it but it wont connect. it stays in a loop saying obtaining ip address, disconnected and scanning and then goes back again to obtaining ip address and so on. i have done 2 hard resets and restarted the router and nothing.btw the router is in the same room just a couple of feet from me.
EDIT : i think i jump the gun too fast. tested my ps3 thru the wireless network and it connects like 50% of the time. again the ps3 is in the same room as the router. went to my cousins house and the phone conected to the wireless effortless on the first try. i dont know if it is the phone or the router.i dont know what to think anymore.

The Sensation doesn't have brilliant WiFi reception and can't hold on to a weak signal if you hold the device, whereas something like a laptop could.
But with a good signal it does work well and for me that's a fair trade off at present. Yes it could be better, but is there a perfect device.
Typing this in Starbucks at present over WiFi and yes in landscape, and I even have my fingers covering the back of the device
Full signal strength. Same at home.
I tried this in another Starbucks, I lost connection every time in landscape mode, returned in portrait, that has been the only time that I could recreate this death grip issue.....

I've seen a few issues lately with the Cisco/Linksys E1000 routers and wifi. 3 out of the 5 i installed in the past 6 months kept dropping wifi,even right next to it. Probably not what you have, but just in case, i thought i would mention it. At $50-$60 they've been a popular model lately.

I am using a netgear n router and I still have signal in the basement and second floor (router is on the first floor)..I haven't noticed any WiFi problems but I have only had the phone 3 days...but I use WiFi calling all the time..

Temporary solution to Death Grip issue

I decided to make a new thread from another thread's reply so more people can see it.
Hi, I dont know where to start....I will try to explain as English is not my native.
I bought my Sensation few days ago and I was very sad as you guys after discovering mine also has death grip issue. I took mine back to the shop and asked them about the problem. They tested my Sensation with their wifi modem and no matter how I holded it in landscape, it only dropped 1 bar. I thought may be because their modem is so close to me so it couldnt prove the problem with them. I took it back home but inside I was still very unsatisfied but wondered why with their wifi, even I tried to walk far a bit but it still didnt drop much.
I went home and tried to configure where the problem is. I remember the shop wifi channel was number 6. Then today, I went to a book coffee shop and with their wifi, I again can hold my Sensation in landscape and the signal was still very strong. I used Wifi analyzer and saw their wifi channel was 6 (normally we leave our wifi at channel 1 by default).
The question raised again why at those 2 places the death grip issue do not occure however it does with my house's wifi. My current wifi modem wireless n, no matter I tried to change its wifi channel to 6, death grip still occured. I change to another old wireless g wifi modem and configure the wifi channel and bump!!! I am writing to you guys in landscape and the wifi is as strong as it can be, only 1 bar dropped.
So to my knowledge and hope, as your hopes too, this is a software related (or maybe hardware related but it will be very sad) that Sensation has problem with wireless n. With wireless g, I havent tested with other channels (1 to 11) but with 6, I am vey happy with the wifi signal right now.
I hope these info would help very much with the death grip issue. I nearly sold my Sensation yesterday after posting it online but I decided to keep it. Now, I am happy that I made the right decision after discover where the problem is.
Edited: I also need our big community do more tests on this and see if the problem has been correctly addressed.

You change channel in your wifi modem/router.

Hmmmm will check that out. I think mine's only a single channel

This may be a resolution depending on 2.4 GHz interference in your area, but I happen to have my access point using channel 11 and the death grip issue is still a problem for me.

[SOLVED?] WiFi and Deep Sleep

Ok, so I think I've figured out why my SR wouldn't go into Deep Sleep when WiFi is on. I think it stems from fact that there's a lot of multicast traffic (IPTV) on my network. I'm a U-Verse subscriber with fiber to the home (FTTH) and my entire house is connected via Ethernet, including the set to boxes (STB). No coax whatsoever is connected. As a result, my STBs share the same network as my non-STB devices (WiFI, Servers, PCs, etc). This causes the STB IPTV traffic to flood the network including the WiFi (my theory). I decided to test my theory by moving all my WiFi APs (3 of them) to a separate subnet, thereby eliminating multicast completely from the WiFi. And what do you know?...my SR goes into Deep Sleep when WiFi is on.
Hope this helps others with the same problem. Switches that are more intelligent can help with the filter multicast more dynamically. Look for something that is IGMP aware and that should help.

How did you get FTTH with U-Verse? It is typically FTTN.

I think it depends on your area. My friend lives in a brand new house about .25 miles from me and he has FTTH, while I can't even get FTTN because my neighborhood is 15 or so years old.

Some wi-fi routers are better than others for this issue.

I've attached a betterbattery screenshot of the wifi related kernel wakelocks I get. This is supposedly from the wi-fi router saying "are you there, are you there, are you there".
This thread talks about the issue and even recommends a router model that does not cause the problem.

The wakelock described in that article was essentially my theory, but for multicast. I noticed the lights on my APs blinking like crazy. I'm using the exact same three APs, just now separated by a router. I'm running DDWRT on three different types of APs as well (Netgear WNDR3300, Netgeard WNDR3400, and Linksys E2000).
As for FTTH, yes...there is a single strand of fiber going into an Alcatel-Lucent NID and then Cat5 to a 2Wire gateway that feeds the Ethernet to the rest of the house. Pretty killer setup. I've got GigE everywhere with 2 ports per room...even in the garage.

Heh, nice. I've got FTTN, but the VRAD is like, less then 100 feet away, so they can easily provide me with higher then promised speeds (I have the 24/3 plan, I get 26/4).

Good to know they are finally doing that. Maybe eventually they can compete with FIOS on speed. Gotta love 44 down and 35 up.

I think my skyrocket is just defective
Well this doesn't appear to be the problem with my Skyrocket. I got home, took it to my friends house and connected to his wifi. (Not Uverse) Phone spent 95% of the time awake and 5% in deep sleep, and it was just sitting on the couch next to me with the screen off, I never touched it. So then I tethered it to my Galaxy Nexus, and the exact same thing happens. I thought maybe this would be the case, as my Galaxy Nexus has no issues going into deep sleep at home on my Uverse wifi setup. I really believe now that there is some defect in this phone, and will be returning it to AT&T for a new one. Or some other phone even.

I have this same problem on my FIOS home wifi. Plagued me for weeks. Looked for solutions, tried everything. The router just sends out too many ARP requests, which constantly wake the phone. Even on boneStocketeer with background sync disabled and no apps installed, not even signed in Google account, I'd still get like 15% wake locks from wlan. I've given up at this point I've tried everything on that router. And since ARP doesn't have a port, I can't block them.
If I set up a separate AP connected to my router with dd-wrt, I could filter multi cast stuff like that?

Wouldn't a simple solution to fix the wake lock caused by wifi be to change the wifi sleep settings so that the phone turns off wifi when the screen is also off?

Well yes, that is what I'm currently doing, but LTE is much more of a battery hog than Wifi. So I get about 12 hours on battery, with fairly light to maybe moderate usage, but better than nothing I guess. It is frustrating because otherwise this phone is just absolutely great. Super fast, and LTE is amazing here in Houston. I will get this figured out eventually.

I can get up to 17 hours with moderate use, I usually leave LTE on all day, and it is a huge drain when the screen is on. But it is better than nothing, better than what I was getting on my Inspire. I think the Wifi also has more to do with the ROM you use, when I was on stock I got better battery life when I used Wifi all day, rather than leave it off and have LTE on.

Well my skyrocket wouldn't take the update that I guess came out just a few days ago (probably because it was root and had CWM on it) but whatever. I was FED UP with this thing. So I downloaded the UCLA rooted ROM and Modem and wiped the whole blasted phone. Factory reset/wipe data, Formatted /system, wiped cache and Dalvik. There was nothing on the phone (except the internal and external SD card where my titanium and nandroid backups were at. Flashed that ROM and Modem. Set up phone, restored JUST my downloaded apps like games, etc. Froze AT&T bloat.
And I no longer have the sleep issue.

I solved restarting my router.
AUs

I just got this issue too.
Tracked it back to SX Virtual server and Dropbox, and now the wakelocks seems to be gone.
What I did was this:
Tried Shark - it showed that there was a lot of packets sent to and from local computers on my network. Nothing more useful info from that.
Tried Network Log, it showed the amounts of packets sent and receieved by Kernel. And most of them was sent to/from local computers, using specific UDP ports.
Used TCPview on the computers to see what it was. It informed that the ports was used by two programs: SX Virtual Server (identical to D-Link Shareport) and Dropbox.
I uninstalled SX Virtual Server/Shareport (it's useless anyway) and disabled Lan sync in Dropbox.
Now, the Kernel network activity is almost idle.
Hope this helps others with this issue.

Wifi Issues

When I move into my room, my laptop gets 90%-100% signal strength from my Wifi, my phone however randomly looses signal completely and especially when I take up the phone to use it. It's very frustrating. Plus when I'm on 3G, it constantly switches from 3G to H too.

The 3g H switching is normal if you are on tmo us and running the eu roms and has been discussed quite a bit
not sure what you mean by losing signal, but i get diff bars diff places in my house. never lose the whole connection as in not being able to dl or browse web
did you run speed tests at these diff locations in house

I think you misunderstood his post. His primary problem is that the wifi on his phone doesn't come close to the signal strength his laptop has when in the same room.
The secondary problem was the 3g/4g switching.
OP -- I have no idea what to tell you.

no, i understood. just saying my phone wifi bars fluctuate even if my laptop has good signal. may just be the way they both display strength readings
i think op should run speed tests btw the two at same time. however both devices are splitting signal so may not be as good as only one running at a time
his speeds may be fine even though bars don't show it

I'm in Jamaica, no T-mobile. I'm not sure if I'm running an EU rom. My problem is that I loose connectivity to Wifi totally randomly in my room with even little motion. I mentioned my laptop for reference... it's like there's poor signal in my room. The phone'll just bit sitting on my bed, I hear an alert and pick up the phone to realize I've lost Wifi.
Speed is not the problem, I've been able to run a speed test to confirm I get the speed I'm supposed to get. Other times though, the speed test could not complete because I moved a little and lost connectivity.

Make sure that your SIM access cover is snapped in place.
It happened to me with the WiFi signal - The phone was losing signal, and had low signal 1 foot away from the router.
I 'pinched' the top-right corner of the access cover (thumb on the glass, index finger on the back cover) - I heard a 'click' and suddenly my WiFi was at full strength. I believe that the WiFi antenna is not connected unless it snaps together.

ok, not sure what to suggest. you could try turning airplane mode on and of and see if that helps
maybe router settings with the phone if you always had the issue
under settings/wifi/ tap on wifi then the 3 dot menu--Advanced. See if Keep Wi-Fi on during Sleep is Always. If not tap on it and change to Always
Also at bottom of Advanced menu is a DLNA setting, you could toggle that
barring that or someone else's ideas--maybe hardware and needs replaced

Try turning on Best Wifi Performance in Wifi, advanced settings.

Turning on best WiFi performance totally killed my battery life, but that may just be me.
If you're losing signal on one device but not another, I'd recommend changing the channel on your router. Interference on certain channels can cause weird issues with some devices. There are apps on the market that will show you which channels are congested in your area.

Hmmm... I'll try that. So far turning on DLNA and Best Performance hasn't made any difference. I'll try changing the channel when I get home later and post the results. I REALLY hope h/w is not the problem.. it's gonna be a hassle sending this back.

It might be worth gently cleaning the contacts exposed when you remove the SIM access panel. As District noted, good contact is necessary for wifi (and probably other features). Dust or a fingerprint may be problematic.

Anything to bear in mind when trying to clean it or adjust it? I'm really paranoid I'll mess it up.

make sure you use electrical cleaner
radio shack sells it, comes in spray can
if you haven't had sim card out or phone long, probably not issue. but, worth try
if you have another router, you can always try that

Nothing seems to work... I'm using channel 11 @ home which doesn't seem to be crowded. I have the same issue @ work with our router. I've been having this problem from I got the phone last week. This is after I initially removed the back cover to first insert my SIM.
I'm going to try and see if I can secure a cleaner... I tried blowing on it mean time. Also turned on DLNA and best wifi performance and all.

DLNA auto-IP setting worked for me.
Hi OP,
I had the exact same wifi issues on my One S. I tried the router at work, the router at home and my mates router with the same results.
Mine seems to work now, with no disconnections or manually connections. What seems to have worked for me -- Wifi - Advanced menu -- DLNA auto-IP setting - toggle on. Then restart, making sure the setting is still set after reboot. Seems to have fixed my wifi issues.
HTH.

WiFi becomes Inactive on idle

I have a OPO, Nexus 5, iPad and Galaxy S5 on the same WiFi network and when my OPO goes on idle, it will stay on the WiFi network but lose internet connection after some time whereas my other devices wont. It's not a matter of the settings because I have left WiFi to be awake at all times and even turned off WiFi battery optimization. I'm having a tough time figuring out why this happens. I have to turn wifi on and off to regain internet.

My only theory is because maybe my IP is not static and CM on OPO is not made to handle it? I don't get why my other devices work fine though. It only happens at home for myself as well

Could be software, does it happen in CM11 nightlies?
Or maybe is the config for the wlan HW, I think OPO has a Qualcomm solution for WiFi, I haven't experienced this in my Nexus 5 (Broadcom WLAN) or 7 2013 (Qualcomm older WLAN I think).

Bump

I seem to be having the same issue. it's weird. I've been trying to do initial upload from Titanium Backup to my Box account and it sucks...
network is a netgear adsl router with the wifi turned off, wired to a netgear router running dd-wrt, and I also have a repeater that's a d-link dir-615 running dd-wrt... yeah not the simplest setup I know
Would be useful to know if those experiencing the issue have altered screen timeout settings.
I was managing to upload ~30mb at a time, but now it seems to be much less - 1mb or less. I'm not sure if that's because I turned the screen timeout down to lowest (15s) to see what happened, but I've now turned it back up to 30 mb but the amount I can upload hasn't increased with it :/ Well - except for once where I did manage to upload 30mb again - which was directly after I turned off adaptive backlight. but then after that it was down to less than 1mb again.
Really scratching my head here.
