Temat: Netgear R6220 i radio 5Ghz

Witam.
Jako że zabrakło mi sił i cierpliwości, więc pisze z zapytaniem.

Nie potrafię zmusić r6 220 do zestawienia linku 867 Mbps na paśmie 5 GHz.

Przeskoczyłem wszystkie kanały, choć od 100 w górę, w moim etaże jest całkowicie pusto.

Wszystkie urządzenia zestawiają się na 433 Mbps.

Przypadkiem zauważyłem wyższa prędkość na paśmie 2,4 GHz.

Wygląda, jakbyś używał tylko jednej anteny.
Próbowałeś połączyć się z nowszego laptopa?
Ustawiłeś AC, a nie jakieś Legacy lub N?

Testuję na Alfa awus1900  więc to RTL8814AU który obsługuje trzy strumienie.

Rpi5 jest na CYW43455  to zrozumiałe że wisi 433.

Ta sama karta z openwrt one zestawia 867 i więcej.

Masz niepotrzebny router, uszkodzony czy nie - chętnie przygarnę go.

Odp: Netgear R6220 i radio 5Ghz

Masz szerokość na 80MHz i MCS index 9, czyli teoretyczny bitrate na 866. Tylko że obecnie klient jest spięty na mniej. I masz retransmisje pakietów z jakiegoś powodu.

Masz niepotrzebny router, uszkodzony czy nie - chętnie przygarnę go.

Wyciągnę zaraz drugą sztukę tego netgeara i zestawie połączenie między nimi.

Edit
Link zestawiony na 866.
Drugą sztuka działa pod openwrt 23 i co zabawne karta Alfa z tym drugim netgear'em ustawia połączenie na dwóch strumieniach.

Hmm, możliwe że coś nie halo w nowym kernelu 6.6 z openwrt 24. Muszę pogrzebać.
