Description

I just flashed an TP-Link Archer C7 v.2.0 (AC1750) according to Wiki with the BB 14.07 factory.bin file. LAN performance is same as with stock firmware.

But Wifi (2,4ghz) performance is *extremely* slow. down: 5mbps up: 5mbps. With stock firmware I got: down: 60mbps up: 15mbps. Wasnt able to test 5ghz yet.

Try using PSK2 (WPA2-PSK)

Replying to jow:

Try using PSK2 (WPA2-PSK)

no difference. i also tried wpa/wpa2 mixed mode. AES and TKIP and mixed. I also tried without encryption (!) - so, open network ... still no difference interesstingly.

Can anybody confirm fully working BB 14.07 on Archer C7 v.2.0 (ac1750) ? What is your wifi performance?

Mine is fresh flashed, and I have all the speed I can get from my line (something like 10 meg of download and 1 meg upload).

I made some iperf tests with server and client in LAN and it appears that WiFi speed is only slow when using the Internet''' WiFi internal use, is nearly same as stock.
