[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.

[Q] Are my signal strength issues radio related or carrier related

I just switched carriers and find that when I am indoors I get very low signal strength if any ay all. When I am in class, especially ones without windows, my phone can not find my carriers network. This was never a problem with my old phone and I usually would get 3 or 4 bars even in lecture halls with no windows or classes in the basement. I am with Moblicity (Ontario) and some times when I search for networks when mine isn't available Rogers (one of Canada's largest carriers) shows up but sometimes not so I can't determine for sure if the issue is Moblicity or not.
My radio is KD1 and I'm running Oxygen 2.2.2 with Netarchy 1.4.0, though I was having these issues on stock rom and kernel. Can any one with more experience on Moblicity let me know if the issue is their network.

I'm pretty sure the KD1 radio is a i9020t radio version and that matters because the 3g frequency used by those carriers has known issues penetrating walls. As for the signal issues, I'm not so certain. In the past there were phone manufacturers that were known for having better signal than other (read: Nokia) and I still think its true. What I mean is my signal with Samsung devices has never been as good as I've seen in other devices. Perhaps its all in my head but I don't know. Have you tried other radios?

KB3 searches and finds available networks much faster than KD1 but doesn't solve my problem

Then I'm guessing your issue lies in the signal strength of the nexus s on its own. To be honest no smart phone I've owned could match the signal of my old dumb nokias and I don't think you're going to find an easy solution

The signal loss that I'm getting seems a bit extreme though. I take 5 steps into Walmart and I can no longer find my carriers network

Hmm. That is extreme. So you've tried kd1 and kb3. Personally I had the best signal on kb3 but I'm on kf1 now. Maybe try that?

[Q] [D720] Poor celldata and wifi reception in known good areas

Hi,
I just went from an HTC Speedy to a Nexus S 4G, hoping for better features and reference Android. First thing that happened was the phone upgraded OTA to Jelly Bean (w00t!) and now that I've had it for a day in the usual locations, I'm appalled at how bad signal reception is. Not "how many bars" reception - I'm talking about the browser complaining about no data connection, 1 or 99 asu, just a mess.
Mind, this is in the same locations where I didn't have trouble with the Speedy using the same carrier on the same plan, so it's not Sprint's fault (this time) and certainly they can't be blamed when 802.11 signal reaches one device but not another in the same location.
Does the Nexus S 4G just have a terrible antenna, is it a bad radio build, or other? I love the look and feel of this phone, using it is very nice EXCEPT for this one not-so-minor issue. I'm not in an area with 4G signal (yet) so I'm leaving that radio toggled off.

Interesting findings on the newest OTA (MD3)

I read about all of the issues people are having with the newest OTA (MD3). I decided to give it a try anyway, because I love writing emails to Verizon pointing out their flaws.
I followed the instructions in this thread: http://forum.xda-developers.com/showthread.php?t=1762709 to go back to stock, using the Official VRALG1 4.0.4 Firmware. I wiped the Data and Cache partitions after installing. After this, I applied each patch in succession BEFORE installing any other software or programs. When I was done, I immediately disabled the Caller Name ID app. I have NONE of the reported bugs:
* Texts send immediately on the first try
* Battery life is no different than it was on the last firmware
* Phone switches easily between Wifi, 3G, and 4G LTE
* 4G LTE speeds are normal
I am no stranger to unlocking, flashing ROMS and Radios, etc, but I am most certainly NOT a dev. I'm posting this information here so that someone with more knowledge than I may be able to glean some information useful to those that ARE having a problem from this post.

I was having issues with the ota and I went back to the oldest update then took the otas.
Then rerooted mb1 and flashed bonestock 2.0 with the mb3 radio/modem....still had signal issues. And that rom has all bloat removed. So I flashed the mb1 radio/modem and now I get better signal.
Ha thats my story.....definitely a mess up from Big Red.

I wiped and then installed the stock deodexed MD3 ROM and firmware and had data issues...low signal, frequent drops to 3g or 1x, etc. Ran it for a few days and it was noticeable wherever I went. Restored my CleanROM nandroid and flashed the MB1 firmware and my signal has been much more consistent again.

I was weary of the rumored issues so I completely wiped my internal storage for a fresh install, and MD3 has been nothing short of amazing for my phone. If anything the only knock on it is that the signal has degraded about a bar in areas where I'd normally have full bars. Data connectivity is fine, data speeds are fine, the kernel with this update deep sleeps better than most that I've flashed in the past month. It's been nothing but good so far

For a device that already had bad radios for low signal areas, the reception issue is bad. It is not like going from great radios to good radios, but going from barely okay radios overall to worse. Everything is relative and the radio changes absolutely suck in that regard.

I"d say this thread is now dead since Samsung / Verizon have now pulled the OTA and will release a fixed version later, That usually means 1 day for Samsung to fix it, and 3 months for Verizon to test and approve the release.
In comparing the S3 to two other Verizon Motorola phones in my family, I find the S3 signal to be as good or better to the Motos when running the current stock software, (not the broken MD3 OTA) . SO I'd say its pretty good as Verizon goes. Interestingly, I find that the Verizon S3 is not nearly as good in signal as my wife's Sprint S3 , Surprising because VErizon and Sprint often share cell towers.

This is exactly the thing. After using MB3 update a whole week, giving it a chance....my phone would still WORK in areas with strong signal, but everywhere else it went from ok to UN-usable!
There is a clear issue here but if you are in areas with only great signal you may not notice as much but it's there.

What they should do is release here first. There are no better beta testers then XDA members and we could probably find every flaw within a day, and heck our devs can probably fix most of them for Samsung anyway.

Samsung usually releases a test release on KIES for their own stuff, but Verizon of course won;t let them do that for Verizon phones because Verizon has their own professional way of doing things....hahahaha
