Dodam tylko, że na tplink ax53 w AC prędkość po wifi na tym samym tel. wynosi lekko powyżej 500Mb (domyślam się, że to pewnie szybszy sprzęt).
Wygląda chyba na to, że mój egzemplarz więcej nie da rady. Openwrt wgrałem specjalnie aby uzyskać dostęp do kanałów powyżej 48 bo na tych niższych w moim środowisku już kilka jest i się nachodzą na siebie. A może mógłbym teraz wrócić do oryginalnego może starszego abym miał dostęp do zmiany regionu i dostęp do wyższych kanałów lub na inny kraj? Openwrt wgrałem z dopiskiem EU bo tylko taki mogłem wgrać.

Takie coś otrzymałem, mam nadzieję, że wszystko dobrze zrobiłem. W iw dev wlan1 station dump musiałem wpisać wlan0 bo tam jest 5MHz

Operacja się udała, openwrt 22.03 zainstalowany chociaż musiałem wgrać wersję EU bo bez dopisku wyskakiwał błąd. Internet jest, kanały powyżej 48 są odblokowane jednak jest pewne ale. Prędkość jaką uzyskuję po wifi 5MHz to 150Mb, po włączeniu w zaporze sieciowej flow offloading, prędkość przy ruterze podskoczyła do 200-220Mb. Czy mogę zrobić coś jeszcze aby zwiększyć prędkość?
