My HD7 worked without issue from the beginning of the year til around a month ago.
All of a sudden, my WiFi became extremely unreliable, sometimes taking an overly long time to recognise or connect to an obvious access point, sometimes finding none at all.
After I do manage to connect wirelessly, I see no speed increase in data transfer to suggest that the phone is even using the wireless link. Web pages sometimes load slower than over 3G. I had read that HD7s have trouble using certain WiFi protocols and adjusted accordingly, but the workaround was to no avail.
Additionally, once WiFi has been selected, I cannot switch it off. I am 'locked out' of the WiFi settings page. When I tap it in the menu it responds as if I've nudged it but it cannot load. The only solution is to remove the battery. On occasion, this stuck WiFi has also caused the capacitive buttons, camera and power switch to become inactive. Curiously, touch screen function seems unaffected.
I thought maybe this issue was tied to corrupt settings with my hub, but changing SSID / WEP key etc etc on my router hasn't fixed the problem, and connection to other open WiFi signals jam the phone just as badly.
I upgraded to Mango in the hope that a fresh OS update may 'rejig' my wireless settings into working, but again, no joy.
Anyone experienced anything similar? My final options seem to be factory reset the handset to see if that solves the issue, or return the handset to O2. (Both involve losing all my data, game saves, application data AND the recently delisted SW: Battle for Hoth permanently.)
Anyone got any other thoughts?
*EDIT* After a bit more research, I found that even when the phone has connected to a WiFi source, by turning Operator Data Service off, you can see that the WiFi service is in fact not doing anything.
I braved a factory reset, managed to whack WiFi on no problem, browser ran at appropriate speed, then everything crashed as per usual, I couldn't connect to the marketplace and had to pull the battery in order to use any of the capacitive buttons. I guess it was a hardware issue individual to my phone after all.
Guess I'll give O2 a ring sometime soon to sort a replacement. Not looking forward to losing all my game progress though it has to be said.
bro i m having the same exact problem havent find any solution yet i even tried to copy and replace the wifi files from another clean htc hd7 but useless when i upgraded to 7740 the wifi worked perfectly for 1 night only then at the morning it stopped working, everything else works great. my theory says that its not a hardware problem cz i used internet sharing which uses the wifi adapter (if i m right) so its a software I GUESS

I had the same problem as well, couldn't connect, got to the point where even the power button stopped responding. Hard resets would only help for a short time and enabling WIFI would never connect right and eventually get me back to the same problem. I then got a replacement device, but it's not much better, I still can't connect to any WIFI, but at least it's not freezing up on me. My solution thus far has been just to avoid turning on WIFI if at all possible, but it's far from a perfect workaround. I'm guessing it's the HTC WIFI driver that's got issues.
i got similar problem.. send phone to service problem was "circut board"
replaced working fine...
when i was using wifi my phone was freezing some menus stop working and i have to remove battery
Hi,
As per the title, I have noticed a couple of strange issues lately. I recently reset my phone and restored the settings (factory reset, Asia spec phone, not mods/hacks).
I have noticed that in my address book I have triple entries for people, some Windows Live entries with the last few letters of the surname chopped off.
Also I have noticed the built-in facebook app is frankly ****, takes ages to update or simply times out.
The browser does the same thing (over wifi) so not sure if it's my connection.
Second issue is the compass/GPS. I have a compass app which now seems to go nuts, it's calibrated but refuses to stay still and I suspect a minor drop may have jarred/damaged something (the phone was thankfully in it's cover so no external damage).
Cheers,
Fz
Those are a lot of things, at least I can comment on the network part:
I own both a Nokia Lumia and a Samsung Omnia W for development purposes. The Nokia always works fine, but the Samsung had a lot of problems connecting over Wifi. It didn't like the Apple Time Capsule, Belkin nor Engenius (the latter being a business grade access point). Symptoms where like yours: Timeouts on connection which could only be resolved temporary by removing the Wifi connection completely and re-adding (by re-typing the WPA2 key).
I was about to give up on this, until in our building a Wifi repeater was added to extend the wifi signal. From then on, the Samsung did connect completely stable. This is strange, because I was nearly always within a few feet from the original access point so a weak signal wasn't the issue here.
I don't know if you can use this info, at least you can try the remove-add of your Wifi network and see if that also solves your issue, albeit temporarily.
I'll try to keep this post as simple and well typed out as possible...
I cracked my screen and essentially damaged the digitizer as touches couldn't be registered at all, so I ordered a newbie off Aliexpress and using the guide on iFixit, I repaired it myself. It booted perfectly and everything works fine EXCEPT for a weird issue I'm having with my cellular data and the network itself not registering properly or something.
I've a SIM card and plan with Vodafone Australia and basically the phone:
- sometimes registers 4G/LTE, but never 3G and 2G didn't seem to want to work
- can sometimes send/receive texts (at random)
- can't make or receive calls
- cellular data absolutely doesn't work at all, nothing will load. I think there was only 1 occasion where half a web page loaded, but that could have been cached
- when the network 'disappears' either I just have a blank network bar in the status bar or sometimes I also get a triangle in the status bar and in the notification pull down area it reads "NO SERVICE - selected network (Vodafone AU) unavailable"
- I also occasionally get a warning that says "Restricted access changed - Data service is blocked" - I called Vodafone and they said there is no blocking or barring service in place on my SIM/service and that the SIM should work with any device it's in
- the device even shows details like signal strength -95 dBm and 43 asu, shows Vodafone AU as my network and even automatically loads the correct APN settings
- I tried an OPTUS Australia SIM and the same thing happened, registers network, shows signal strength, APN etc, but nothing works!
Prior to doing the repair I was using a Telstra 4G SIM and everything worked flawlessly right out of the box. Never an issue. I'm pretty sure both providers even run on the same bands.
I have tried the following to solve the problem, to no avail:
- different ROM and kernel (stock CM11S, Temasek CM12 w/ AK kernel)
- fastboot erase modemst1 and modemst2
- different modems (44S, 05Q)
- changing settings in *#*#4636#*#* menu (LTE/GSM auto, and the rest)
All I have left to try is to go see my provider and request a new SIM.
I'm thinking maybe something happened when I disassembled the device, like I may have damaged the part of the main board where the SIM registers. Could this be the cause? Surely not,as I do get that temporary LTE registration...
Also note that I'm 99.99% sure it's an international device, not a Chinese one, as it came with CM11S and the Aliexpress seller told me so.
Any advice? HELP!!!
Never mind. Realized I hadn't connected the antenna back to the main board. As I was putting the main board back in, I tore off the flex cable that connects the volume rockers to the main board. I now have a 1+1 with no working volume buttons. What a waste of 5 hours and a few hundred dollars. That'll teach me to DIY.

That just teaches you to be careful. We have all done it from time to time. I tore a bunch of flex cables in my time. Now I don't. It is all a learning process
Similar Problem
I have a similar problem. After replacing my screen I have no service unless I have line of sight to a cell tower. I mean REALLY close, and stepping behind a wall will make the signal disappear entirely. I'm assuming there was damage to the antenna in some way, does anyone know where I can get a replacement antenna or have any other solution for me? Everything is connected properly, no apparent damage, works great IF I can see a tower and am in close proximity.

Similar problem here.
After replace my screen I got poor signal. The reason I replace the screen is because of water. I still get signal but not as good as before. I also lost signal sometimes. I wonder if it because of the water too.
I don't think it's because the flex cable. I've double check, the cable is attached correctly. I've tried to unplug the cable and turn it on. I can see the difference, when the cable is unplug I got no signal at all. If it's because of the water then which part should be replaced?
So I've had my m8 since launch, about May of 2014. I've never once had a problem with my wifi, until last week. All of a sudden, I noticed all of my wifi connections (home, work, etc) are all extremely slow. Speed tests are barely getting 1mbps down or up, and the test itself is very erratic, bobbing up and down the whole time. All my other devices are fine, and nothing with any of my wifi connections has changed. I uninstalled about 3 apps that I had installed within the last month, with no change. Verizon sent me a replacement m8, and I got it yesterday, loaded up all my stuff, and low and behold, still slow wifi.
After talking with numerous Verizon techs, they can't solve it, even after multiple factory resets. However, this morning I saw a post while googling it, not an m8 but still android. They said that if Bluetooth is on, but not connected to a device, it could cause issues. So I turned my bluetooth off, and speeds were perfect, getting exactly what my internet connection is. Turned it back on, and back to 1mbps.
So one, why is this happening? I've read that the bluetooth and wifi antennas are the same, and that could cause interference, but it should not be this bad. Second, why did this just now all of a sudden start? I didn't usually leave bluetooth on, but I got a new car about 3 months ago, and decided to leave it on to automatically connect when I'm driving. But it was fine until last week, why the change?
Have you discovered anything new? I've had my Verizon m8 since April 2014 and have always left bluetooth on for my fitbit to sync. I only recently started having problems and can't identify any recent update that happened this month that would cause it. When bluetooth is on and a device is connected my wifi performance is very slow - 100+ ms ping, 1-2Mbps up/down doing a speedtest. Turn bluetooth off and speed test again then wifi performance jumps to 20Mbps up/down with 12ms ping times to the same speedtest server.
I have factory reset my phone 3 times, changed wifi channels, tried 2 different routers and 1 access point. None of the wifi changes affected speeds until bluetooth was turned off. It seems to be a little quicker 3-5 Mbps with bluetooth on and no devices paired but still that's not acceptable.

I too have had bluetooth on for months to be able to connect to my car, never had a problem until about a month or so ago. I did two factory resets, and everything seemed to work fine, but after a day or so, when all my apps were back on the phone, it would start up again. I have a hard time believing a specific app is doing this, unless it was one of the HTC Home updates or something.
Verizon sent me a replacement M8, I got all my apps on it, and the same thing, after a day or so it's super slow with Bluetooth on, horrible ping and less than 2mbps down and up.
So then I contacted HTC directly, did all their troubleshooting, factory reset, and it's still there. They sent me a replacement as well. I turned it on, but did not put my sim into it. I spent 2 days with it, and only downloaded the Speedtest app, nothing else. Speeds are fine with bluetooth on. I then downloaded the rest of my apps (I actually do have quite a few apps, so if it's one of them it will be a pain to figure out which one). It's been two days now and speeds are still good with bluetooth on. Later today I'm going to offically move over to this phone and put my sim in it.
It's just really frustrating to keep turning bluetooth off and on again, and there should be no reason for this to be happening out of the blue all of a sudden.

Strange issue, but from how you described it, it must be a 3rd party application. What I would do in this situation, is do the factory reset, and download 5 apps at a time. Until you narrow it down to the 5 apps that are causing the issue, then you can narrow it down much easier out of the 5 applications. A pain, yes. but once you figure out the app that's causing the issue, you may decide you don't need it, or you only use it once in awhile and can remove it, until you need it, or possibly download an app ops application from the Playstore and remove the Bluetooth permissions and see if that fixes it.
Best of luck.
Seems to help...
I just tried the solution offered in another forum (xda won't let me post the link so I'll copy and paste the information here:
Open page with the available "Wi-Fi" networks (Settings, WI-FI)
Tap on the "3 dots" in the upper right corner
"Wi-Fi Direct"
Tap on the "3 dots" in the upper right corner
"Rename device"
Replace "Android_ed2c" with "HTC One" (or whatever you want) and hit "OK"
Before doing this I had a 300ms ping when Bluetooth is on, and very low bandwidth. Now with Bluetooth on the wifi ping is around 50ms (normal for my home internet) and the bandwidth is back to normal. Time will tell if it sticks, but so far so good!
So I had been running all my apps on my replacement phone for about a week now, and have had no problems. The other day I officially swapped my sim card into this new phone, and for two days now, it's been fine. Bluetooth and wifi are on constantly, and I see no issues with bandwidth. So who knows why the last two devices had a problem, but for now it seems to be fixed.
Having the same issue, originally posted on reddit and then found this thread: https://www.reddit.com/r/techsupport/comments/3kv6z6/wifi_issues_with_multiple_phones/
Turned off bluetooth and it's fine... Will be experimenting with my gf's m8 this weekend.

Same HTC M8 issue - very slow WiFi when Bluetooth is running
Same problem on an HTC M8... speedof_dot_me speed test shows 96 ms latency with D/L at 0.07 mbps (really!) on an 11 mbps router. Turned off Bluetooth, and voilla! Latency dropped by 85% and WiFi speeds increased by a factor of 60! I suspect an HTC issue since an August or September update... since this wasn't occurring prior to August.
Verizon sent me a replacement M8 that was on 4.x.x android. I updated via on-air update (not rooted) to Lollipop and installed all my apps. Everything was fine. That night, it did a security update and, since then, my wifi+bluetooth were horked when turned on together.
Do, I did a factory reset (which doesn't undo the updates), but since doing the factory reset and installing just the basic Play-store updates 24 hours ago, the problem is not back.
I'm going to slowly add back my normal apps this time.
Solved on one plus one
Hello, i had since two weeks the similar issue. when bluetooth is switchef on (unconnected), wifi is very slow. in the past this different, so no issue with hardware and frequencies. Finally, I found out that it was linked to an App that accesses Bluetooth.
In my case it was the App Accu-Chek, I read in a big forum that it was linked to a Garmin app.
Uninstalling the App solved the issue.
My wife has a similar issue on Stock Galaxy S4 mini with that App.
This is definitely app-related. I tried force closing out of a bunch of apps that weren't related to the video I was playing and it seemed to fix the bandwidth issue with bluetooth enabled. Guess I'll need to experiment with closing certain apps until I find the culprit.
I was having this same problem. It looks like the RetailMeNot App was the culprit for me.

You sir deserve a cookie. Thanks for pointing out the worst app of 2015.
Solved on my Phone!
I used to have the same problem. I am having a Sony Xperia Z1 Compact and a Smartband Talk. At the beginning everything was fine but after sometime (strongly caused by a software related issue) I begin to face the same problem. While bluetooth is on WiFi bandwith dropped to a very little amount (around 0,02- 0,01 Mbits/s). Then I read somewhere, about how to verify whether it is a software or hardware issue via checking it in the Safe Mode. So I unpaired by smartband talk and uninstalled the smartband talk software (smartband talk requires a bluetooth connection for functioning). Then restarted my phone in to safe mode by tapping and holding the power off on the shutdown menu. I downloaded the smartband talk software and turned on my bluetooth and paired my smartband talk again. Then restarted my phone in to normal mode. And voila, problem solved.
It is not a guaranteed method but worth to try.
Wish you good luck.
