Have you double checked to make sure it's not capitalizing the first letter in your password on the new ROM when you enter it? Also, a battery pull may help. Leave the battery out for at least 1 minute.
Have you tried to connect to another router?
I've found that some phones can and will react differently to apps and ROMs. What works perfect on 1 phone will not necessarily work perfect on the next. Hopefully that's not the case here and it's just a setting that's messed up somewhere. Keep an eye out to see if anyone else is reporting the issue.
Mine is working great. Like I mentioned earlier, I've connected to several routers already and it worked without a hitch. Matter of fact, I haven't had any issues whatsoever. I've even got the ZRAM enabled and all is working as it should.:thumb:
Hopefully you can get it figured out.
