[Q] Do I need to reflash my WiFi?

So after I successfully rooted my phone, I did flash the radio and WiFi. Custom ROMs have worked pretty well. But lately, I have noticed (and I am not sure to what degree this was going on before) that my WiFi signal is quite bouncy. This is the case no matter what WiFi access point I go to.
Is it possible that something with my phone got messed up? Is it recommended that I reflash the WiFi? Should I just try a different ROM?
Any info would be greatly appreciated.

By "WiFi" do you mean "WiMax?"

I mean whichever radio is responsible for my WiFi... so is the WiFi radio and the 4g radio one in the same? If so, the question still stands... would flashing it again possibly fix fluctuation in signal?

Im still having this problem. Anyone else? In fact, I was at a friend's house and was using his WiFi router for access and it was slow. I told him we probably need to reboot his router but he didn't think so. My speed test with his router was 800Kbps - ~ 1Mbps... and I know I was testing his WiFi... not my 3G.
He then testing from his iPhone 3GS and was getting ~ 7Mbps (about what should be expected)... so clearly the problem was my phone.
Did a clear cache and dalvik and still not better. My radio is still bouncing.
Anyone have any ideas?

???
As far as I know, there is no such radio for WiFi???
WiFi improvements come through software updates from HTC, but I've never seen a flashable update??
You can only flash the evo radio and wimax.

Wifi on the Evo sucks. I have the range issue regardless of what rom I use. My iphone doesn't have an issue.

This must be hit-or-miss. I vaguely remember some others complaining about WiFi (wtf..lol). I get a great connection at my house, I can use WiFi out in the yard, and the only time I've gotten less than 8megs down I was also watching a movie on Netflix and dl'ing a torrent.. and even then I got over 4m/s

my wifi was fine until i flashed to this latest leak.

Trouble with WiFi, Android 2.3

I have some problem with Wifi on my Desire. I have installed Ginger Villain 2.0, but when i searh for wifi networks, i cant find my network. There are some other networks, but not mine.
Then i've restored Android 2.2 rooted, and everything is OK..
PS i also tried other 2.3 roms, and there is the same problem
Please, help me!

Change the channel for your wireless in your router settings. Change it to 12 or put it on auto. They work best but change it to what ever works for you.

I too have this issue with works WiFI
it only and issue on 2.3 ROMs, and is happening with every 2.3 ROM I try.
I can connect to home and mates WiFi no problem. I can connect to work no problem on any 2.2 ROM.
I have loaded a 2.2 ROM, signed into the network, saved the details in several WiFi managers, the reloaded 2.3 and the phone cannot see the network
What does 2.3 do differently/wrong compared to 2.2??

So no developers or anyone has any clue as to why this is happening in 2.3??

I hate to rub this in your face but I don't have any issues with wi-fi. Check my signature for my setup. Maybe there is a problem with the WiFi standard a/b/g/n, try changing the standard on your WiFi router (if it allows you).

Many people on the net have the same issue. And it's been the same with every 2.3 ROM I have tried. Yet every 2.2 Rom has worked fine so that suggests to me it's 2.3 issue and not an issue at my end.
I an unable to get access to the router. It's works one and while I have the password I will be shot if caught in the server room
So far it is only works router that fails to show up.
I installed WiGLE and it found if fine. The first time. Since then no go.

If you can see and connect to other networks, it could be a problem with yours. Hidden SSID? Wrong channel?
Maybe a radio update is needed?
Look at this. Maybe helps

Yes I believe it is a hidden SSID. I cannot change that.
I am on the latest radio.
I will read through that and give it a go and see what I can find
Cheers

I owe you a drink!
In that link it talks about setting it to scan 14 channels. I did that an BINGO straight away picks up the work WiFi on channel 13. SO it must be default 11 or 12.
Cheers mate!
To the OP, give that a go!

[Q]Could the wifi router be the culprit?

I have previously posted on how my WiFi was only working via a ****ty app.
Now I have some more info that makes me beleive that our home wifi router is the cause of that.
I went to my friends house and WiFi worked completely normal there, so it must be the routers fault right?
I have also reflashed the radio, so it probably isn't it's fault.
It all started happening when I updated to the OTA 2.2
Any help on how to fix this?

what about flashing a custom rom?

Well, I'm running CM7 with 2.3 and it's still the same :/

I don't have pc wifi to experiment with. But I will try to tell something.
Wifi on wildfire has the support of b and g networks by default. So no wifi "n" network on wildfire by default. There is a chance of difference in these network types between ur wifi and ur friends wifi, such that it works only with ur friends one.
And I think I saw somewhere in development section that someone made wifi "n" network working on wildfire. But Im not curious about it since I don't use it.

But what's really odd, is that it worked like it should on stock 2.1, so obviously 2.2 ****ed something up...right?

[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.

htc m9 wifi problem

hello , i have problem with my new htc m9 it cant connect to wifi networks ???
wifi turned on but cant see or connect to any network
my android os 5.0.2
please help

Have you tried a Factory Reset?

Same Problem
Exactly the same problem I think the problem from sim.. Slide out and do restore factory settings... Wifi will appear relates and you can contact. But if you put sim you cant contact and dont see the network.we need update from htc because this problem in some contry
I from syria ????

I'm not having the exact same problem but I am having a problem with WiFi
Yesterday I received my wife's M9 upgrade and started setting it up. I noticed it was going REALLY slow downloading over Wi-Fi, so I activated the SIM and it dropped off the home network. It immediately picked up pace and apps began making download progress. I have more than a dozen other devices working without issue on my home network. When I reconnected it and attempted to reach any website, it just stalls.
Tonight I'll try pulling the SIM out and / or Factory Reset to see if I can get it working.

same problem
i have the same problem what should we do?

I returned my device and got another new one. Immediately out of the box it seemed to be working better but developed similar issues. I disabled a setting named minimize battery use on Wi-Fi and that seems to have improved it, but it still seems to have issue with my 5mhz 802.11AC router.
I think we can live with it the way it is, until they push a fix. Hopefully a fix anyway.

Seems to be an issue with N only 2.4Ghz and 5Ghz band networks. I set my 2.4Ghz to auto (g/n) and removed the 5Ghz SSID from the list of known networks and it's working great. YMMV

DNS issue?
My problem is similar to what Jason V described. My phone connects to my home WiFi okay, but the internet connection alternates between working very slowly, or not at all. Strangely, removing the SIM card from the phone fixes the WiFi connection, but as soon as I reintroduce the SIM card, the WiFi issues return.
I'm going to attempt changing the DNS server to see if that helps at all. If it does I'll let you know.

problem completly solved with new update (1.32.401.17) from dear htc

Still...
Mine version is 1.32.841.15 but the problem is still there... I can't use Wi-Fi....
I could before but now after a few updates I can't... ( Just to be sure that we have same problem, I can turn Wi-Fi on but it doesn't show any networks.)

Solved
Simply update to latest build which as by now is : 1.32.501.17 and fortunately solve 2 M9 devices wifi for me.

I was chatting to HTC for about one hour! But our biggest problem was that they don't know there is such a problem! They thought it's a problem just for me.
I informed them about it (at least, informed the chat person!) so I think we can expect an update from HTC in few weeks...
And that's weird that we can use Wi-Fi Hotspot but not connecting even finding networks!
I think the best is to wait a little...
But I'm still really confused that how did some other people updated their phone to 1.32.501.17 not 1.32.841.15 ?!
