Sir/mam

I was updating my router and something wrong while upgrading it.It went to recovery mode and now i need the firmware to fix it.I brought it from a local Bangladeshi reseller.He said to download the firmware from the official Website of tplink Bangladesh.But the official website of tplink Bangladesh doesn't have the firmware download option and other region firmweres doesn't support the 100-165 5ghz wifi channels other firmware are limited to 36-48(im not sure about the number) channels that doesn't support in Bangladesh as a result the 5ghz ssid won't show and some region doesn't support fixed 80ghz width.I need the firmware of TP-Link Archer Ax23 v1.0 with 5ghz channels that supports in Bangladesh and fixed 80ghz width only support.

Thanks and regards
