Hi, my Tplink Archer 1750 V2 US version is having a problem after i upgraded to version ArcherC7v2_en_us_180114. My 5 Ghz wifi stops working . After restarting the router , it works for 2 to 3 hours and then 5GHz disappears automatically. That wasn't happened when i was using the previous old firmware.

if anyone have the following firmware version for Archer 1750 C7 V2 i would highly appreciate. 

Firmware = 3.13 34 Build 131217 Rel 60903n

Thank You.
