I have Transit Max hardware revision 2. I am running firmware 8.1.2 build 5114. I am having a problem getting a lease from my local WIFI provider. I have a Verizon sim and T-Mobile sim. I upgraded to firmware 8.3 to see if that would fix the WIFI connectivity issue. After the upgrade my T-Mobile would just constantly reset. I power recycle did not help. I switched back to firmware 8.1.2 and the T-Mobile now works. Is there a problem with T-Mobile on firmware 8.3?
The WIFI does work in either case. I think it is a provider problem.
