Has anyone experienced issues with Xoom Wifi with Wifi strength after Jellybeans update? It seems that the wifi strength in Xoom is significantly less. I've confirmed by holding another tablet side by side, and the other one shows 3 bars whereas Xoom barely shows one.
I did notice that older software releases had issues but those updates don't quite apply for Jellybeans. Any pointers are much appreciated.
Now that's weird, I notice more WiFi strength in JB compared to ICS. I'm using TeamEOS nightly builds for MZ601.
Well I believe if you want more WiFi strength you can always edit the kernel to give out more voltage to the wifi interface. Of course you will need to compile it in the correct environment as well or else it won't boot on your device.
never noticed that on mine, always had great wifi signal strength, ics, jb, EOS, CM, etc

Hi,
I recently returned my first Gtablet due to the fact that it would never wake up from sleep mode (had to do full reset). The second one I have now is working great except the wifi signal strength on it is pretty terrible. I have a Linksys E3000 with DD-WRT on it and even if I hold the Gtablet straight above the router I get only 2 bars of signal on the tablet and about 75% signal strength in DD-WRT. I've tried this with another access point as well and still have weak signal with this Gtablet.
The first GTablet I had didn't seem to have this problem.
I am running Vegan 5.1 and I tried both with and without Pershoot's latest kernel with the same results.
Any thoughts on settings or anything that might increase my wifi signal strength? I cannot use my wifi from the other room because of this, I routinely did this on the first Gtablet that had the wake issue. My archos 101 also works fine.
Thanks,
Sean
I have the same problem. However on my n-network I have full signal strength, but that one I cant connect to. Running Vegan 5.1
On both my laptops I get full bars..
I am running Vegan 5.1 Beta on my Tab and when it was right out of the box I had this problem but ever since I rooted and installed Vengan I have not had a proble... I do notice that when it goes to sleep it turns off Wifi i guess to concerve battery but comes back on in a few seconds... I know not any help but perhaps your just getting a bad batch.. good luck..
I'm running the CM10.1 nighty 12/26 on my gt-p3113. I have noticed that the wifi doesn't show as strong of a signal as the stock jelly bean rom. Does anyone know if the wifi is indeed a bit weaker due to software management, or is it a bug in the display just showing less signal than it really has? For instance where i am right now I have 3 of 4 to 4 of 4 bars on stock jelly bean touchwiz, but on the cm10 only 1 or 2 bars. I had to be within 10ft of the access point to get full bars on CM10, but stock i can be two floors up and 30 ft away and have full bars.
I also have the issue where it doesn't wake from sleep sometimes and has to be reset, but that has been documented already. I would have posted this in the CM thread but it wouldn't allow me as I'm too new to xda. And yes i did search the wifi issue but didn't find anything...

So a friend told me that the CM10 roms measure the strength differently than stock, the CM10 will be something like -96 and the stock will be something like -104 so the cm10 will show just a little less signal that you really have and the stock will show just a little more than you do... But the antenna should function the same under both. I guess CM10 under-compensates to keep you from connecting to very weak connections that are extremely slow. so I'm not so worried now, but I would like to find a way to modify cm10 to measure the signal strength indicator just a bit differently maybe -98 or -100.
I've noticed the wifi strength in the notification isn't always accurate. Most times it will indicate that I do not have a signal when, in fact, I do. You can see in the screenshot that the download speeds are fine, and everything works as it should but the wifi signal definitely shows that it's weak. This was while sitting right next to my router. Also, my laptop and ipad show full signal strength in the same location. I get a full bars sometimes, usually only for a few minutes when I restart the device. This is a rooted razr hd running jelly bean, btw. It's not a big deal to me, but it is a minor annoyance and I'm curious to see if it happens to anyone else.
I have the exact same issue. I can be right beside my router and it will show weak signal. Then when I am not paying attention the signal is full. Minor annoyance but I would this fixed...using ics 4.0.4

Hi guys,
A couple weeks ago my Xoom lost the ability to efficiently scan for wifi networks. It takes several minutes for any networks to show up at all, but once my saved network appears it will automatically connect (and stay connected) even though it will drop all found SSIDs many times there-after. Can anyone shed light on what could be causing this? I'm hoping it's not a hardware issue.
The attached screenshot from WiFi Analyzer illustrates exactly what is going on. My own network uses both 2.4Ghz and 5Ghz, the 5Ghz doesnt seem to drop at all (you can see it in the screenshot as well), maybe that's why I'm not losing internet connection when all of the others drop... Also it seems that often another particular channel 1 2.4Ghz network seems to stick around when all the others drop. Sometimes only half drop, then go, then the other half appears, then they all go... come back, etc. No other devices in the home are having any problems.
I am running the stock factory android (rooted), and have never flashed any other builds on this device, I will try EOS soon but I can't imagine what may have happened kernel/OS side to cause this behavior... any help would be appreciated, thanks!

I have been having ongoing similar issues with my MZ604 WiFi Xoom, but seemingly only at home with my Netgear router. My 2.4GHz connections randomly drop, but the 5GHz connection has been rock solid. The stability could be an issue elsewhere too, but I don't use wifi outside of my house much! It was these drops that ultimately lead me to experiment with custom ROMS.
Most of the custom ROMs and kernels have reduced or eliminated the issue for me (both EOS3, EOS4 and now OMNI). The ElementalX kernel seems to make things significantly better for the 2.4GHz connections. However, the v1.3 and v1.2 of the ElementalX kernel that I tried with the EOS3/4 ROMS introduced way too many sleep-of-death issues which were way worse than the wifi issues. With the EOS ROMs, I could not use the ElementalX kernel as the sleep-of-deaths were so bad. I had to resolve myself to kernel in the EOS ROMS and use the 5GHz connection at home (which has more deadspots )
The version of the ElementalX kernel in the Omni bigpart 4.4.2 ROMS, however, seems to reduce the 2.4GHz wifi drops substantially (but not completely eliminate) and fortunately does NOT have any of the sleep of death issues. So, ultimately I'm VERY happy with the OmniROMs even though the wifi drops are not completely gone - the OmniROMS have made my GUI much smoother/faster.
I should track when the wifi drops occur to see if I can see similar channel discrepancies. My brief observations to date seem to jive with what your saying. When the drops occur and I go into settings to try to reconnect, a lot of the wifi SSIDs have disappeared - after some time they reappear. It would make sense that it could be channel related.

Hey slow thanks for the reply man, this is all really good information for me, I haven't research too too much into what I want to put on my Xoom, most of my time here has been spent on a phone I just replaced. Glad to see I'm not alone on this issue, I haven't read of anyone else having the same issue and misery loves company. I've honestly yet to try my device somewhere other than my home as well, but I just cracked the screen on my Nexus 7 without even dropping it and now I'm back to using this work horse and I honestly missed it. Xoom is a rock and despite its age has far greater build quality and durability than the N7, that said I want my damn wifi going strong!
I used to be on a Linksys WRT-54G with DD-WRT firmware but it recently fried and we switched to my roommates Apple Airport Extreme (and now have 5Ghz in addition to the 2.4Ghz). Not knowing if the problem started occurring simultaneously with setting up the new router I tried killing the power to my router and to my surprise the wifi on the Xoom started working fine again, but only for about 20 seconds, and now it still looks exactly like the picture I attached above no matter what I do. So probably just a coincidence and no proven correlation there I suppose.
I'm gonna try the kernel and builds you mentioned and I'll report back with my results, thanks man. If anyone else is having similar issues please share.

If you go straight to the OmniROM bigpart 4.4.2, you will not need to install a separate kernel - a version of elementalX is built in.
If you try one of the EOS ROMs, you can stick with the stock kernel that they contain, or you can install the optional elementalX version that is compatible. I had to stick with the stock one because sleeps-of-death on the elementalX one.
HOWEVER, the OMNI ROM needs the BigPart partition before you can install it; the EOS ROMs do not. As such, the OMNIRom requires a few more steps to install if it is the first non-stock one you try.
I highly recommend the OMNIRom.
Thanks slow! So here's something wierd: I'm at my girlfriend's place right now and all networks are working just fine. I can connect to hers (AT&T U-verse, 2.4Ghz) without issue. Attached screen shot shows typical scanning behavior (the top red line is the network I'm connected to).
Now I'm back to thinking that something in or near my home is causing serious interference in the 2.4Ghz range. Two recent changes in my home include installation of a DirecTV dish (bringing the building's total to 3 dishes) and that damn Apple Airport Extreme router. I am going to kill all power in my breaker box when I get home to see if I can narrow the problem down to something I actually own vs interference from a neighbor. It still boggles my mind as to how this possible interference is only affecting my xoom and no other devices...

I'd be curious to hear if you discover anything interfering. I haven't looked further to see if it is only certain channels that drop out.
I should also comment further on my experience with custom ROMs and 2.4GHz wifi issues on my Xoom. Generally after installing a new ROM after a full wipe/factory reset, 2.4GHz wifi is good and stays good for 3-5 flashes of new nightlies of the given ROM. However, the 2.4GHz stability then starts to decline and I end up going back to my 5GHz question at home. The 2.4GHz stability is restored if I do a factory reset/full wipe before flashing a nightly. However, I don't bother doing a full wipe/factory reset unless I have to because I'm trying to a ROM from a new source. This is because I haven't bothered to get Titanium Backup going and having to download all my apps again, as a result of the full wipe, is a pain in the butt!
I have an unlocked HTC One S that has major signal issues. When the phone boots, there's no service for a few minutes before it decides to actually kick in. WiFi and everything seemed to not work but after putting it into "Best Wi-Fi Performance" mode it seems have resolved. But the cellular signal drops constantly. I've read that this is quite the common issue with these phones and am wondering how they are so popular if this is the case. Regardless, has anyone discovered the reason for the issue or some sort of jimmy rig to fix this issue?

please mention your hboot , radio , Rom.
I'm having a similar problem. Occasionally I get a signal strength of 2 billion dBm. (255 asu)
What seems to be alleviating a lot of it is a set of mods to build.prop.
ro.ril.fast.dormance.rule=1
ro.ril.gprsclass=1
ro.ril.hsdpa.category=1
ro.ril.hsupa.category=1
ro.ril.hsxpa=2
These settings are the absolute slowest possible, but they do seem to be improving the connection quality.
Same problem to me. I have a new S4 from 2 days, bought "refurbished" from aliexpress at a good price. It's new, looks great but signal and in call audio quality is weak.
Phone works good on "GSM only". If i set GSM/WCDMA, I lose signal and phone stops itself.
I started with stock 4.0.3, phone stops itself.
Updated to 4.0.4, phone doesn't stop but no signal with WCDMA enabled.
Then I unkocked, rooted and tried Miui V5 (4.1), same problems.
After installing Maximus HD, I had signal also with GSM/WCDMA, but immediately I installed newer firmware and signal was lost. (Works only on "GSM only").
Tried also Beanstalk, CM11, MagioRom, SourcE, Slim kat. No signal with GSM/WCDMA.
I don't know if works with Maximus with older firmware, or it was only a coincidence. Don't know what firmware was at that moment.
Went to a bigger city and 3g worked excellent.
Returned back to home, no signal with 3g enabled.
I guess my phone is weak at signal.
