What kind of issues are you talking about ? I'm having major wifi issues with my 10.1 NOT LTE. Wifi keeps disconnecting every 10 minutes. I tried:
In my router:
- Disabling MAC filtering;
- Tried using both DHCP or static IP;
- Using Wifi G only (instead of N);
- Disabling B/G protection;
On the tablet:
- Same issue with stock ROM and custom ROM;
- Same issue with stock kernel or custom kernel;
- "Wi-Fi Timer" option is OFF
- "Keep Wifi ON during sleep" is set to ALWAYS
- Turned off Avast! & Malwarebytes (just in case)
It's major pain because I can't play any games reliably. I can't send back the tablet to Samsung because the KNOX warranty is void.
