I cant upload beta firmware for manual select band
Hi,
Recently i just bought this router. But i do have problem with connection because my ISP at my home strong signal is only band 5. This router always randomised the band and channel make it unstable. I read in tp link community, they said have some beta test firmware that we can choose what band to use. I did try download and upgrade it but it said the version i upgrade is not same with my device version. This is my router detail
Firmware version
1.3.0.0.9.1 v0001. 0 Build 200402 Rel.63263n
Hardware version
TL-MR6400 v3 00000002
Mine is APAC v3 version.. I got an error 4506 everytime i tried to upgrade to the beta firmware.. Please i need it ASAP as now i cant even use my router
