[Q] WiFi sucks on CM7

Okay so on CM7 my WiFi signal is just way weaker than it should be. I'm in the room right next to my router, and I have like half of a WiFi signal...On every Sense ROM I've tried (and the stock ROM), my WiFi works perfectly fine, yet on CM7 it's complete garbage...Does anybody know how I might solve this problem? Somebody suggested I try a new radio. I had been using stock, but I flashed the Telus radio and it was exactly the same. Also, why doesn't CM7 have an option to use like Advanced WiFi or w/e (where it works better but uses more battery, it's an option in the stock ROM)?

I'm on CM7 also but my WiFi is the same on this as it was on CoreDroid and stock ROM. I had the Atrix prior to the Inspire and will say the WiFi on that phone was annoying. I could stand right near my router and I'd have 1 bar of WiFi like really?

My Wifi was great on coredroid and inspiredsaga, buy not cm7 for some reason

That's strange. Does it run slower or just show less signal? If it runs at little to no noticeable difference is it a big deal?

I'm not sure because I don't really browse the web on my phone through wifi, I usually only download Apps and whatnot.
I'm not sure if it's slower, but I lose connection sometimes. I'll be downloading something and it will say "connectivity lost. rety?"

Are you checking signal strength in decibels or just bars? Decibels is the only way to make a fair comparison. Some ROMs may have a different bar/decibel ratio. 4 bars on one ROM might be 3 bars on another for the same given signal strength.
FWIW a couple of weeks ago I was curious if different ROMs affected signal strength. I tried rooted stock, CoreDroid, TPC, CM7 and Ultimate Droid and noticed no change in decibel signal strength. Wifi Analyzer and Network Signal are two such apps that will show decibels. Be sure to measure signal strengths in the EXACT same spot and take an average of signal strength (as they will vary a few dB normally).

One thing I noticed since switching to CM7 is that my signal strength is more accurate. My laptop shows 3-4 bars when I have it right next to my phone, and on the stock Sense ROM I was showing max signal. Now on CM7, I get 3-4 bars of Wi-Fi signal strength, so I think it's all a matter of how it measures. If you are seeing serious performance issues, then that's a different matter.
FWIW, I have not seen any Wi-Fi performance issues between CM7 and stock ROM.

I had the same issue with CM7.
At one end of my house, one or zero wifi bars with CM7. Kept flip-flopping between wifi and 3G, disrupting use.
With stock ROM or TPC Stock Optimized at the same location, phone gets one or two wifi bars and I can surf without the phone flip-flopping between wifi and 3G.

That is just a slight radio mismatch issue between CM7 and whatever radio you're using (it sounds like you're using the stock radio). I had the same thing happen to me using CM7 with the stock radio. This radio is fine for a lot of ROMs, and it gets good signal strength, and phone calls were no problem, but using CM7 in 1-2 bar wifi strength areas it would flip between wifi and cell data way more than it needed to. Flashing to radio 12.48.60.23U_26.08.04.07_M3 and flashing the RIL file HTC-RIL_2.2.1003G fixed this problem for me. Now the phone stays locked onto weaker wifi signals much better.
I read somewhere on this forum yesterday that one of the new nightlies for CM7 is going to have a different RIL in it; maybe it will address problems like this.

same here
i was having issues with my wifi and signal bars w/cm7 also, so i just switched to ace.

[Q] Lousy Signal: Anyone Else?

Just checking to see if anyone else with an Inspire on AT&T has experienced a signal dropoff in the last two or three days. One day I'm pegged at 4 bars WCDMA, now I can't seem to get out of GPRS/Edge. Seems it coincides with the rollout of the update. Anyone else getting crappy reception in the last few days?

No good reception

Reception is all right for could always be better, still waiting for AT&T to get the 4g ball rolling

Folks, I'm looking for those of you who have had LOSS of signal in the last week. Please no "mine sucks" or "mine is ok" kind of posts, i only want to hear from those of you who have had a change.

Does anyone know how to check the status of AT&T's cell towers? Is there a website that will show where they are and what their operational condition is?

You can call att and tell them where you are. They will give you information on the towers in your area.

Signal is crappy, but hasn't changed in the last few days. You should call AT&T and check with them

Well, just as I was about to call AT&T to find out what the heck might be going on, I now see my signal is very strong again, but with UMTS as the network type, though I'm showing 3G in my notification bar.
So, is UMTS the new 4G network and they were just changing the tower over the past few days?

They have been updating towers all over...So to answer your original question, yes I have experienced some bad signal at times, but has returned to a good signal after they finished updating whatever they were working on....

maybe this explains my many dropped calls in the last few days..

What are you showing for network type?

Actually it depends on where Im at in my house...i can move 15 ft and itll pick up an Edge signal....then switch to H+,which is still just 3G for now until LTE network is up and running...Ive only seen 3G once or twice since Ive had the phone...Also just a side note...Im on an unrooted, untampered with 1.84 ROM...Based on your posts, your rooted and using a custom ROM, issue may not be the phone or the towers, may be the ROM your using,unfortunately with the way ATT provisioned this software...you may have issues with certain things using custom ROMS....

I doubt that using the Custom Roms are the main issue. Many of the custom roms are using Stock Kernals and Radios. <- those are the two main contributing factors to cell strength and battery life.
I run MIUI on stock kernal now, with the new ATT Radio .26.06.06.30_M and have no issues. Denver CO Area and run full bars or -70 to -87 dcb at almost all times. Great download speeds.

Incorrect to a point....if provisioning isnt correct in the rom then there will be issues, att is trying to be slick in a lot of ways these days...

When i use Stock roms my signal is steady on H+ n a lil bit on Edge but mostly on H+.
On custom roms i stay on Edge.. H is rare or just dont stick
n yes im using the stock kernal n radio

Update: turns out they were working on the tower(s) in my area. Signal back to normal. Thanks for everyone's feedback.

this happened to me last month, and now today is happening again lol. seems like they are working on towers a lot recently in my area. if i go to another city i get full bar H constantly...oh wells hopefully they will finish all the tower work soon.

Has ICS killed the reception?

I am on tesco mobile (02) currently and its reception is normally very good, I get full bars most of the time on 2.3 but when I updated to ICS, the reception doesn't go above 2 bars
Has anyone else had this problem and is there a possible fix of shall I wait for the next update from Google

Instead of looking at the bars have you checked the actual signal strength? Are the numbers matching with 2.3?

i feel it gets better comparing to 2.3 ...

Exactly ... See what sugnal strenght you get in -db unit rather than the bars ... in GB the bars are only 4 while in ICS it's 5 or 6 if I'm correct ...Use an app of necessory ... or look for it in the Settings/About phone/Status

JellyBean WiFi signal

On ICS, in my room I get 3 bars when connected to WiFi and it never drops.
On any JB ROM, my phone sees the connection at 3 bars but when its connected its only 0-1 bar. 1 if I'm lucky. I'm sitting right next to my router and I'm getting only 3 bars.
I changed the WiFi region code to USA already and doesn't help at all.
Is there a radio I should flash or a modem? I'm on the latest firmware. 3.33 I believe. I'm on Bruce's cm10.
Is this a known problem?

if you are on tmous i believe wifi disconnecting\not connecting is a known issue as well as low signal on jellybean all around. U should consider urself lucky that you get any wifi connection I can't use jellybean roms because I need wifi and when I activate wifi it keeps losing signal then eventually causes my phone to reboot.

I don't get data at all on Cm roms so your doing pretty good with data and Wi-Fi.
I am however on a jelly bean rom that I received both good data and Wi-Fi. It's paranoid Android. I'm happy with that rom. It seems the others I can't get any data.best wishes

[Q] My data signal is weak

I was wondering if I should update the radio, or the modem as they call it on the s3. If anyone has anything to say about this problem please get back to me. Thanks

Which rom are you using? 4.2.2 have always "shown" lower signal than i was actually getting, but i always had good signal and never dropped calls.

I'm running jellybam 7.5 now. I was running liquid v 2.2, which had a weak signa, is why I flashed jellybam. Thanks for the reply

I flashed the newest modem recently and I noticed more signal in my basement (where it was usually very bad) but curiously less out and about in the city (where it was usually spectacular)

I just flashed the latest modem, and my signal just grew 3 plus bars. Awesome. Thanks
