I just recently started having a problem on CM9 (don't have any other information anymore as I tried updating with jc's latest CM11) and thought updating to CM11 would fix things. Well, same problem, unfortunately. Any fixes on this? Any time I try to connect to a wireless network it looks as though it might and ends up saying "disabled" under the network name.
So, it has been awhile since I've been to this site and I thought I'd check in to see if there was progress on a Nougat install and, more importantly, a solution to the Wi-Fi card being disabled that many of us are seeing. To give a bit of history, I have a 32 GB Touchpad that I bought on firesale in 2011. The Wi-Fi card works great in webOS, but obviously with no future for webOS, I decided to load Android on my Touchpad in a dual load with webOS. Originally, I loaded one of the CM loads of Android 4. Wi-Fi initially worked great. One day, out of the blue, it just stopped working. I thought maybe the card had died, so I booted into webOS and sure enough, Wi-Fi had no issues. I've been searching for a solution to this issue for years - I've tried loading 4.3, 4.4, 5.x, and I believe even 6.x and nothing has ever solved the problem. I've since blown webOS away but I'm confident that if I reload it, Wi-Fi would work great.
My symptoms are the same as yours - if I go into settings and enable Wi-Fi, it spins for awhile and then disables it. I really have no idea what's going on. It isn't like I want to use this tablet as a daily driver or anything, but I'd like to use it as a home automation controller/dashboard mounted on a wall and for that to happen, I need Wi-Fi to work in Android. It doesn't appear that the issue has ever really been resolved. At this stage, I'm even willing to send my Touchpad into a developer for testing/troubleshooting so the problem would hopefully be resolved once and for all. I suspect that some of us have a slightly different revision of the Wi-Fi card in our Touchpads, but I can't be sure and who knows - maybe a developer already knows that exact issue but can't fix it.
