[Q] IceColdSandwich 4.0.3 wifi drops

Hi all,
I'm new to this forum, thanks for all the information and nice tutorials.
I rooted my phone from the default and latest HTC sence version to the Ice Cold Sandwich 3.0.0.
I really like the new version, however I notice some wifi drops as I had before a specific HTC update.
Does anybody know a solution for this problem? I can't post in the developer forum due too not enough posts...
Thanks in advance.

The ROM is a port so plenty of things are bound not to work at times. It's a common issue and is easily solved by flashing a more stable ROM.

you could try WiFix Manager from the marked see if that helps you..
i think most of the icecream builds have many bugs yet..
and proberly many with the same problem as you
so if you used the search function under the rom you use
you would proberly see many with the same problem and fix to it

The wifi doesn't "drop", it's just that ICS has different levels of measurement than HTC, so 2 bars on sense may be 1 bar on ICS

Thanks, but i'm really noticing drops and even dead spots like i experienced before.
The HTC update than solved this for me.
When I for example hold my hand fixed above my phone the wifi signal will drop very fast and after some time the connection is even lost.
As I said I also had this problem before with the HTC software, however there has been one update regarding wifi problems and this solved this issue for me.
I don't know whether there is a possibility to see what has been solved in this update and to implement it somehow.
kind regards

That's because you're blocking the antena inside which makes the signal poor. Try not to cover the plastic in the back of the phone all the way.

I got the same problem of dropping wifi connection but I managed to work. I used to run ttorrent even I m not downloading anything.
There's an option "best wifi...." Something in advance wifi menu in sense ROMs, that solves dropping wifi connection.

That's a Sense only option. AOSP doesn't have that but has a different set of setups which can enable better wifi performance. There is also an application called WiFix which fixes some known issues about wifi.

[Q] COS-Bravo-ICS - problem reconnecting with 2G or 3G after Wifi connection

Hi,
I'm using the COS-Bravo - ICS [21-May-2012] on my phone. Since the first version I flashed I've been having the same problem, but as the ROM is under development, I thought the problem would get fixed in some update. It still hasn't so I'm reporting it.
When loosing a WIFI connection, the phone must switch to a 2G or 3G network. This doesn't happen. Mostly the WIFI icon disappears as it disconnects and the signalstatus doesn't change (no Edge, Gprs or Hdspa is added). When I go to Airplane mode and back or when I switch between 2G/3G, the connection is repaired and the data-connection works again.
I've also noticed this problem with other ICS roms (Sanvold and BCM)
Does anybody have a clue what this could be?

Radio
What radio version do you have?
Its recommended to have the latest radio.
You can find the latest radio here: http://forum.xda-developers.com/showthread.php?t=687464

Of course the latest radio. ;-)

I have the same issue. When turning wifi off, my Desire doesn´t get a mobile connection though it´s showing, that i would be connected.
Switching to 3g and back doesn´t work for me.

Same problem here with Sandvolds ICS
I have this problem nearly 2 years now on every rom (stock eclair, froyo and cm7) and on every radio version, so I guess it is hardware depended.
Correct me if i am wrong.
What I do is switching to airplane mode and back, so i have to enter my PIN again.
Maybe there is a soltution, cause this is really drving me nuts
Thx

With the newest version (01-06-2012) the problem seems to be solved (for me). Perhaps you should give it a try.

I´ve been glad to hasty. It still does not work. Neither does it to switch between 2g and 3g. But the airplane-"hack" does work for me too.

I have same problem with COS ROM. Mobile internet connection after using telephone as wifi modem do'nt working successfully.... i need reboot phone, airplane mode not solving this problem..

Hi!
Same problem here (HTC Desire Bravo, GSM, Cos-Bravo 1st June, latest radio).
This "bug" is present in every ICS Rom and as well in some GB Roms I tried. So far, the RSK ROM Sense 3.5 with amaze cam doesn't have this issue.
I hope someone will get to it. I'm more than ready to donate if someone will be able to solve this out with next build.
Thanks.

To judge from my own experience - I'm still seeing this problem six months later - it has not been fixed yet. Or does it only affect a subset of Desires?
I'm experiencing it using a GB ROM - Mildwild 4.7, though it was there in 4.6 as well. I can only assume it is in the ROMs, as I get it on two different handsets, a PVT3 running radio-5.17.05.23 and a PVT1 rrunning radio-5.11.05.27.

Remove the skipbrokendatacall entry in build.prop file. This will not completely resolve the problem but will make it very much manageable.

Check your APN Settings and try to set APN-Type to default only.

[Q] CyanogenMod 10: Wifi Problem?

Hey There,
I've just installed this fine ROM today, and it seems great,
but for some reason, the wifi reception is BAD now.
It works fine if I seat near my router, but if I move 3 meters away
it looses the connection ... and says the reception is POOR.
Any1 else has this problem?

Which version of CM10 did you flash, if it's anything older than beta 1 try flashing Beta 1 ? if you still have problems after Beta1
Try flashing a different kernel and see if that resolves your problem. (if i can spare you some time, try faux123's kernel)
http://forum.xda-developers.com/showthread.php?t=1647993
And then if you still have problems.
Try running the Viper ROM 2.6.0 with the Butter hacks runs very smooth.

Thanks for the quick replay
I flashed the "[08-09] [ROM] CyanogenMod 10 - Endeavor Unleashed" rom.
I don't think this is the same cm10 everyone's using.
and I don't really understand, doesn't the Kernal comes with the rom?
Can I change it without changing a rom ?

I notice the same problem a few days ago (I think is since I have install CM10). I have switched on OrDrost since 2 days, I tried the Faux kernel and finally I just revert to full stock rom and my wifi signal haven't change :/

But on the stock rom WIFI was ok.
Update: Ok I did the "Squeeze" test. Wifi is great whn I squeeze
So it is a hardware problem?? How it only started after I put CM10?

Have you reinstalled the stock rom since you have the problem?
I don't know if CM10 is the cause, or it's a coincidence..

there's an UNOFFICIAL release at the moment which may fix some issues, though I've not noticed anything and I've had every release since A10 installed, so it could be a hardware issue.

I'm on the newest build of cm10 and my WiFi network is fine. I can from leedroid and so far just the same. I do have a tiny bit of earphone cable between my back and hard case which gives me my full bar due to the hardware fault.
Couldnt be bothered sending it back. So this works. Bit did recorded it with HTC so they know I have the fault.

Not yet, I really hate the stock rom.
tgcp, Where can I get this rom?
(Although it really seems like an hardware problem,
I heard the latest stock update helps a little so there
might be a software solution)

But if you use Cm10 without that little earphone cable, the wifi won't work good?
BTW, what does htc support ask to fix the problem? Do they care you rooted and unlocked the device?

The cable is about 3mm in lengh and as i have a hard case, its enough to compress the connection inside the phone where the fault is.
Htc would of course fix it, but whats the point if the phone is working and its not noticeable.
I would have had to relock bootloader and go back on stock rom.

I can't move more then 2 meters from my router or it disconnects.
Does your wifi issue not that bad? (without the cable's help)

With out my fix the signal is a joke. 1 bar when 3 feet away. Wasnt usable.

Problem is I can't get back to stock! from what I understand the Stock RUU for my phone wasn't released ...
Do you think HTC will be "understanding" and fix the wifi issue even with a custom rom?
(they'll know anyway that I opened bootloader)

Try flash the Rom with the stock kernel, that will surely solve the WiFi problem.
Sent from my HTC Desire C using xda premium

Did you not do a backup before installing custom rom. Im positive that even if you relock the bootloader they can see that if they went in to recovery. But unlikely. So if you flash stock rom and re lock bootloader, remove root you should be fine

Hi, try using tbaldens CM10. It can be found under HTC ONE X ORIGINAL ANDROID DEVELOPMENT. I found this to be the best CM10

I have been chasing this problem ever since installing CM10 on my Evo 4g LTE. I was getting 4 times the wifi distance on the stock rom. I go about 30 ft. outside the office and wifi drops. Also, what is the most annoying... I stream over our LAN, and when the screen is off, it turns wifi off after a few minutes. (and yes, the check box is checked to keep wifi alive). I've also tried all of the wifi fix apps and none work. If I leave the screen on and stream........ it is good anywhere from 1/2 hour to an hour, then it will just stop. This kills my battery of course. The problem 1st occured when I first bought my OEM 4g lte, but there was an option in the advanced menu "best wifi performance", after checking that, it worked great, then I switched to CM10 and I now have the wifi issue, and there is no option for "best wifi performance". I've tried a couple other jellybean roms and they have the issue as well. This is driving me nuts. I hope someone finds a solution. I don't think the average person would find this as a problem, but when I stream over the net and move all about the shop, it is unacceptable.

I faced the same issue but not on any other ROM. It was specifically with Cyanogenmod 10. I was upset because it gave me the best results but the wifi result was really poor.
However, since I work with wireless networks often, I decided to explore Cyanogenmod's wifi settings. I noticed that if you go in the Advanced Wifi functions (which you can find in the Wifi options menu) you will notice that there is an option called "Wi-Fi Region Code".
Apparently, this option allows you to select the frequency bands your device can operate and is subject to the different world regions. It is quite possible that your Access Point follows the regulatory body of your country and you should know which frequency bands they allow the AP to operate. Due to this it may be just that the Cyanogenmod, by default, put you in a different regulatory domain and limits your frequency band to a subset offered by the AP. Hence, this effectively limits your wifi reach even if you are sitting right next to the AP.
I chose "Japan" since I remembered that their regulatory domain allowed for quite a large subset of frequencies that are allowed on the WIFI spectrum. This immediately increased my received signal strength and I did not have any problem since.
I suggest you play with this, it is likely that your android device will start functioning correctly. However, if you are facing this limited frequency issue on more than one device and that too running different operating systems and different wifi hardware...chances are that your wifi router is malfunctioning. In that case, replacement or repair of the Access point is the best alternative.
Good luck. I hope this solves your problem.

No WIFI on AOSP ROMS - BOUNTY $20

Will pay someone to help me UNDERSTAND and fix this issue I have.
I have ATT HTC ONE M8 - S-OFF, CID 1111111
I have successfully used all Sense ROMs. But if I flash ANY AOSP ROM I have no WIFI whatsoever. It connects sometimes and drops right off. I can't use any non-Sense ROMs because of this and I am starting to get PO-ed.
Please help, reward in it.

I was told that wifi is like this because of HTC having a closed source wifi driver. Regular unsecured networks you should be able to connect to, but secured connections you'll have to be extremely close to the router to connect. Frustrating, I know.

Yes, that information is all I have been able to uncover actually. But I dont understand how its not really a big deal for anyone else? Haha.
I mean all these people seem to be using these AOSP ROMs....but I am the only one who seems to care that I have absolutely no wifi sitting on my couch at home?
Strange that people are just 'dealing'
Anyway - thanks

It is and has been a big deal for others. You can see this in pretty much every AOSP thread we have here. Only a few of you guys are experiencing no wifi at all. There's only a couple of options that can be done next to "just dealing" which is digging into the code and trying to fix it or using a non AOSP based ROM.
Try this if you want and test your wifi and let me know if it's any better.

If I got great 4G signal here at work I probably wouldn't mind as much about not being able to connect to the network here where you have to log in to use the free WiFi. I can never get to the acceptance page. Since there is free WiFi here I might as well use it but I can't. CarbonROM seems to be PERFECT aside from the WiFi issue plaguing all AOSP ROMs at the moment.
I just hope that someone can confirm that it is an issue that is being looked into. I'm a little curious as to why HTC would lock down its WiFi drivers...

I have had the same problem as you on all AOSP roms except Liquidsmooth. I flashed liquidsmooth beta (from the HTC m8 original thread) and wifi worked while it didn't on all of the others. The most current one is running on 4.4.3 and that may have something to do with it. I really want to flash Paranoid but Im waiting on 4.4.3. Liquidsmooth is a very stable rom if you want to check it out. I saw on a PA Google+ post that the 4.4.3 update may help fix this issue so I would wait... Although, I could be wrong

I hope that it gets resolved soon. I am so sick of using Sense. In fact, I hate all stock interpretations of Android. AOSP or die.

Have you tried playing with the WIFi module? If it is working on one, then you should be able to use it's WIFI module on another. If you aren't getting any wifi at all, well that sounds like a kernel module issue to me.
What kernel are you using?

My problem isn't connecting to WiFi, I can do that just fine. I haven't tried connecting to a secure password-protected network yet, but "Guest" access points I can't get to the page where you accept the terms of use unless I'm a few feet from the router. I don't know of any ROM that has allowed me to connect farther away from it yet. All the ROMs I have tried seem to let me use unsecured access points with no problem.
On AOSP ROMs I've tried the included Kernel baked into the ROM and Excaliber 0.3.
On Sense I'm on Faux.

Cyanogenmod 11 Unstable mobile signal and WiFi

Hello there everyone,
So, I flashed the CM11 M11 --> cm-11-20141008-SNAPSHOT-M11-m8.zip yesterday on my HTC One M8 and everything went smooth as silk.
The only issues I'm having right now are:
1) Mobile signal strength is very unstable, especially on LTE, it can just randomly drop from full bar to nothing and then back again. I know this is software related since on my stock Sense 6.0 I had perfect reception no mater where I go. My M8 is the Asian model (M8x), it's basically the same and it's GSM unlocked but of course have support in different bands. Any ideas what can be the problem? By the way, on Sense 6.0 I use to see the "4G" icon and now it's LTE, does it matter?
2) WiFi would randomly just freeze - it looks like it's working and signal is great but there would be no internet connection. Never happened to me before using this ROM.
Any help would be appreciated since I LOVE CM11 so far.
Thanks,
Nimi.

It's either an issue for people, and reading the last several pages of the rom thread would have talk of it if it's a bug.... Or it just is what it is.
I'd just try another rom and see how that is. ?

same problem
