Wi-Fi connection issues - Barnes & Noble Nook Tablet

Is anyone else having problems getting a Wi-Fi connection with one of the custom ROMs?
I had occasion to fire up my BNTV250a running CM12.1 and found that I could not connect with my network. So I brought out my BNTV250 running AOSP 7.0 and tried it. Also no success. The last time I used both of them they were fine. It seems unlikely to be a hardware issue since both tablets are failing in the same way.
I thought it might some sort of outmoded security stuff in the ROMs, but again, that doesn't seem to fit the scenario since they were connecting previously. And anyway, I have an old no-SIM phone running KitKat and it has no trouble connecting to the same Wi-Fi network.
Any ideas?
Edit: I took my tablets to my local library and had no trouble connecting to the WiFi there. I can't figure out what is going on at home since I had to change the password on both tablets when we got a new router some time ago and they were working fine then. To my knowledge, no changes have been made to the router since. This is basically making both tablets bricks :-(

Here is what I have learned so far.
The 16 GB tablet (AOSP 7.0) magically "fixed" itself. It will now connect to my home router (ATT, relatively "new" sometime in the last year or so).
To get the 8 GB tablet to connect I had to flash a CM 11 backup. It picked up the router right away.
Restoration of a (at-one-time-working) backup of CM 12.1 resulted in a tablet that would not connect to the router, as per my experience with the existing CM 12.1 installation that started all this.
A completely new install of CM 12.1 also would not connect to the router.
A completely new install of CM 13 connected to the router right away.
(alas, CM 13 is where the tablet starts to become flaky....)
A completely new install of LNOS 14.1 connected to the router right away. Presumably AOSP 7.0 would as well since it works on the 16 GB tablet.
So.....it looks right now like there is something in the CM 12.1 ROM that is not letting it play nice with the newest WPA etc. security settings.
Really odd that CM 11 still works.

WiFi dis(re)connection/dropout thread

My own experiences were as follows (on a wide variety of routers, both G and N, running anything from stock Linksys/Cisco to Tomato and DD-WRT, using no encryption or WPA2/AES):
- ALL stable CM7 releases: Completely unreliable. Would connect initially, maintain communication for maybe 1-2 minutes at best, then lose connectivity (although the icon would remain green)
- Beta 3.1: For the first time, WiFi was rock solid. Worked absolutely flawlessly.
- n86: WiFi broke again, in much the same (apparent) way as stable.
It would seem those with WiFi problems (all of us?) fall into one of two categories - those for whom WiFi worked great with the .32 kernel until n86 (that would be me, and from what I've read, several others), and those for whom WiFi *never* worked properly on .32 _until_ n86, who now work flawlessly.
Is this a reasonable assumption? If so, I would guess this change:
Don't renew the leases if mDhcpInfo.leaseDuration is not positive
actually made things better for some and worse for others.
Anyone else with thoughts on this? The inability to maintain connection long enough to even copy a few hundred meg video over Samba is frustrating to no end - especially when, for a brief but glorious time, it was perfect!

I own two NC and one is on n86 and the other is running Phiremod 6.3 which is Cm7 based with zero wifi issues
I've seen one WiFi issue:
My WiFi graphic indicator would show only the lowest signal strength. I have no idea if the signal is that bad, or it's just a bug.
I've not seen any disconnect issues.
In fact, my Nook Color has been more reliable with WiFi than my iPad 2!
I've connected to public WiFi, WiFi routers running stock Netgear, Tomato, DD-WRT, etc. No issues.
I've mostly ran the CM7 nightlies. I've used a little of Phiremod and Stock, but by far the nightlies.
I have this problem currently on both of my nooks running n87. its been happening for me since .32. weird thing is, it only seems to happen on my wifi, when i go to work and connect its all fine, or if i steal my neighbors wifi its fine too. but if i connect to my home wifi, it connects for 1-2 mins, then disconnects me but still shows that im connected. i even replaced my netgear router on stock firmware(i did try updating it) to a linksys that im currently using dd-wrt on and its still happening.
Have you tried N86+ with the OC Kernel and WiFi update?
Homer
What is this "wifi update" you speak of?
WEP works every time for me. Anything WPA protected is hit or miss.
I have a NC running CM-N86 and no WiFi issues.
Also, I my coworker's NC running CM-N87 doesn't have any WiFi issues either...
1) I have been running CM7 since it has been available. I have not once seen problems with WIFI. At home I have a linksys WRT54G router running DD-WRT using WPA2.
2) you posted in the wrong area. This should be in the CM7 user thread or the general forum area.

i wasnt aware of a wifi update >.>
CM7 Nightly - NO issues with Wi-Fi. Use it everywhere Wi-Fi is available...
i actually only have issues when i'm connecting to wpa2 enterprise. after disconnecting and trying to reconnect, the credentials no longer work. i have to delete and recreate it every time.
i'm running nightly 87 w/ oc kernel on emmc.
No wifi issues here either. No matter what I connect to.
Also... this should be in general... not dev section...

How about here. You must push the system folder contents or flash.

thats not a wifi update, its the OC kernel. and at the very least my issue occurs wether i have the oc kernel installed or not

Yeah, I'm running 5/23 and I still have wifi issues on my home router (D-Link with WPA2-PSK).
Oh well.
re: general vs. dev...I respectfully disagree. I submit there _was_ a change in behavior, in the negative, for some users beginning with n86...and that is most definitely a -development- concern.
Rodney
The issue relies in the type of security and if you are using Aes or tkip. I have confirm this changing my router settings. The problem is that if I get my setting for the nook, tgen I have to reboot the router almost daily for my phone to connect.
I'm on nightly-87, Dal's 1.2GHz OC Kernel 5/23, and I'm experiencing something very similar. I went from 7.0.2 to N87 without a hitch, but I immediately started to see the WiFi icon go gray and lose it's connection. I was forced to restart WiFi as a remedy. As of today I'm getting something closer to what you're talking about; when WiFi turns on, the nook will infinity cycle through: disconnected->connecting->disconnecting->scanning. I've wiped Cache, Delvik-cache many times to no avail. Also tried re-flashing N87 and the OC Kernel, which did not work. I'm still not able to connect to my home network(netgear, WPA). But, after enabling/disabling airplane mode, I was able to connect to my LG vortex and obtain the interbuttz.
The last time I did a fresh install was around N20 something. As far as possible causes to this erratic and ethereal bug, my money is on certain update paths for both the OS and Kernel having different remnants. Example: with 87 different experimental OS installs and, to a lesser degree, the three different stable OS installs. There are technically !90 different upgrade paths. Compounded by being paralleled by kernel installs, but I believe when a kernel is updated the former is completely replaced instead of merged. I'm not calling out the Dev's, it would be nearly impossible to foresee and head-off all of the permutations of merging 87+ releases.
I'm no expert, just my two-cents. I'm not really concerned about this as a long term bug. There are fine people hard at work, and unfortunately have far more pressing issues to contend with. It's a sad reality that community driven projects, notably the nook Color, rarely reach maturity or complete/efficient hardware-software integration before the allure and newness of a product wares off.
As a consumer of .rockbox, a Linux based OS for G5.5 ipods and below, Of which I've been using for years and years. And, I would say it's just now becoming 'perfect', even with it's lack of support for many peripheral devices. I'm long term with my gadgets.
I'm rambling now.
Hope this helps to narrow down symptoms and possible causes.
I love spending time on a post, just to realize after it was posted that I was typing in the wrong thread reply tab. Oh well. Que Sera, Sera.
I have the reverse experience of the OP.
I never had any problems with Wifi ever, until the .32 test builds, when Wifi would stop without notice, requiring a disconnect/connect. This caused me to go back to a .29 stable.
Perhaps what the OP is suggesting is that the change, that was reversed, should be a toggle/option, rather than changed and then changed back.

[Q] Wifi Disconnecting (GSB3.7)

I just got the thing and it came with GSB3.6 and it had SO many problems i put 3.7 on there and most where fixed, but my wifi disconnects every 15 seconds or so. any known fixes?
EDIT: Tried OMFGB, Same problem. i hope its fixable. someone help meeee
Check Settings, Wireless & networks, Wi-Fi settings, then tap Menu and Advanced. Change the 'sleep' policy (try "Never") and see if it continues disconnecting.
I would like to think that the default setting, "When screen turns off" does not kick in when there's an active connection...
I've used GSB v3.7 (Odex) with my WiFi without any problems.
Based on the fact that you observe the same symptoms with two different dev ROMs, I would suspect that the problem is either (a) your WiFi hardware, (b) your WiFi router, or (c) a software incompatibility between your WiFi router and the Eris' device driver (very similar from ROM to ROM).
You could try installing a completely stock ROM, for instance the
[ROM] HTC Eris March 2011 OTA Stock ROM - v2.41.605.6
(Note that although this ROM is "completely stock" and "not rooted", flashing it does not touch your recovery boot, so you treat it just like any other dev ROM).
Running this test - if you still experience the problem - will exonerate any Eris dev ROM, and you have a couple of options at that point:
- see if your WiFi router has a firmware update available (router firmwares contain bugs, too). I have experienced incompatibilities with the Eris which were solved by flashing WiFi routers to newer firmware.
If you try that and you still experience problems, you actually still won't know if the problem is (a) or (b) - but if you take your phone to a Starbucks or other place with a WiFi hotspot available, and you still experience problems of the same nature, then it is time to suspect that the problem is "(a)" - hardware trouble with your handset.
good luck

I switched the router from duel band N to single channel G, and now i only disconnect every 45 minutes or so.
also i tried swapping routers to a diff one, and then my dads DX, his wifes Droid, nor my Eris, could connect at all, under any settings. so it seems Android has alot of issues with wifi? anyways, i still disconnect, but not enough to bother me. thanks for the replies!
as much as it might suck, you should try doing a full wipe of data/dalvik and see if it fixes the issue. i had gone from 2.4 or so up to 3.7 without doing a wipe, and eventually things started to happen (widgets would not show up for new programs). i did a full wipe and everything is working great now.
I also am having wifi issues, didn't have them til I put the gingerbread cyanogen rom on.
I will do some more trouble shooting today and see if I can narrow down some of the variables. I have a Buffalo router with WPA2 for security on it. Some have suggested the security, but then I've talked to others that have WPA2 set up and no problems.
The wifi was working previously, did a full wipe of data and dalvik when I installed. I am running 3.2 or something close to that, haven't upgraded to the most recent version yet.
SO. Theres my info. But I love the rom and won't get rid of it, even if it is the rom.
My husband is fine just running 3G.
i have a linksys wrt54g running ddwrt using wpa2 with no problems, gsb 3.7 on my eris.

In general, WiFi compatibility from clients to APs is far worse than most people expect; I've experienced interop problems with all sorts of gear. It is hard to draw general conclusions, as the results you get are highly dependant on specific hardware models & firmware versions.
About the only generality that can be stated is this: the more bells and whistles you enable on the AP, the more likely it is you will experience a problem.
FWIW, my GSB 3.7 Odex Eris seems to work flawlessly with a Linksys WRT54G with WPA2. I think I have multiband (A/B/G) turned off in favor of G-only.
cheers

Yeah I wouldn't say that either. I've had my Inc for a year, never had any problems with it, and like I said before this rom, no problems with wifi.
I also have an android tablet. No problems with stock.
So clean install with 3.7, did data wipe and cache, first thing I did was try to get wifi going, all it does is scan. Entered my SSID and everything. Says it's not in range. Bah.

[Q] Jelly Bean causes my router to reboot...

I've tried a few different versions of CyanogenMod 10, included the latest SD card img from succulent and it reboots my DLINK DIR-655. This is really odd as it's the only device to do this. When I run the stock B&N software (1.4.3) it works fine (also CyanogenMod 7 worked fine too). This is extremely annoying and means I can not use Jelly Bean on my Nook until I find a solution to this problem. Any suggestions? Thanks!
There is no reason I can think of that would cause your router to reboot simply by running a jb rom...
Do you have logging enabled on the router to see why it's rebooting? I've never had any issues with my Netgear router running jb. Both my NT and Skyrocket are running 4.2.2 with no adverse effects.

I'm having the exact same problem with the same router (DIR-655 HW:A4 FW:1.35NA).
So far the only remote luck I've had is change WPA2 Encryption to TKIP, instead of TKIP/AES. Forcing it to TKIP seems to have fixed the problem, but I've only tested it for about 15 min so far.
Strange thing is, when I first loaded CM10.1 onto my Nook Tablet, I didn't have any router reboots for quite some time, like about an hour... then the rebooting started happening.
Anyway, let me know if forcing TKIP works for you.

Thanks for the info. However, I actually think the problem is the router itself. It's either going bad or overheating since it's in a cabinet under the TV. It's now starting to reboot when my laptop (Lenovo T-510) wakes up. This never happened. I'm going to move it to a cooler location and see what happens, or I'm just going to bite the bullet and purchase new router soon.
Still, I'd like to know how your experiment works out.

So it looks like TKIP stopped my router from rebooting, but I soon realized not all my devices supported TKIP, a couple were AES only. My final solution was to create a guest network that was TKIP and the main network as AES. Now I use the guest network for my Nook and everything else in the house uses the main network. Everything has been up and running for a couple hours now without any router reboots.

Which tether app for 10.2

Running cm 10.2 and I can't seem to get WiFi tether to work..running the 3.3. The built in cm hotspot seems to work..devices connect but get no internet
Sent from my EVO using xda app-developers app

Ya i ran to this issue for the last year. Some peoples phones work with the native wifi mine never has. I have tried the trevemod, wifi was less then 2mb. Then i found the 3.2 and 3.3 versions of tether. It takes a lot of tweaking to finally to get it to work but they do work. Problem i always had is if i used my phone as it was going sometimes it would turn it off. And after an hour the data would be less. So i would have to reboot phone then i would get over 20mb again.
So not sure if it works on 10.2 but i came a crossed a thread in the OMni 4.4.2 Rom posed by SIlentstyder. found here http://forum.xda-developers.com/showthread.php?t=2495109&page=24
He came a crossed it for use with the NExus 5 via sprint. There are step by step screen shots how to do it. I gave it a shot and it worked like a charm. I have full 30Mb LTE + utilizing the native tether. It worked on the OmniRom. Then i went back to see if worked on DirtyUnicorns 4.4.2 and it worked there as well. Havent tried it on the sense roms but would assume it works there as well.
Only issue i had found is with dirtyunicorns rom, which i like the best out of the kit kat roms, is the internet works fine. i can connect any device but i cannot open my work email on any device connected to it. as well as that vpn doesnt work. So i went back to OmniRom and i can do this no problem. So not sure what thats about. I havent seen any post that have that same issue. So hopefully there will be an update soon and i can try it again.
Give it a shot, just make sure to save a copy of the settings.db if it doesnt work.
