Temat: D-Link DIR-853 R1 - oba radia pracują na 5 GHz ?

Witam.

Przechrzciłem kolejny router na OpenWrt. Tym razem jest to D-Link DIR-853 R1.

Czy to normalne, że oba radia działają na częstotliwości 5 GHz ?

Odp: D-Link DIR-853 R1 - oba radia pracują na 5 GHz ?

Ogólnie - tak. Pierwsze masz tylko 5GHz, drugie jest dual band, a openwrt ustawia po prostu domyślnie drugie pasmo. Możesz sobie to zmienić na dowolny kanał z 2.4 (oczywiście o ile w ogóle drugie jest dualbandowe, a nie że ktoś dał ciała i nie ograniczył radia do wymaganych pasm).

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

Odp: D-Link DIR-853 R1 - oba radia pracują na 5 GHz ?

Też właśnie zauważyłem, że mogę na tym radiu wybrać N-kę (i wtedy mam do dyspozycji kanały na 2.4 GHz) lub AC i wtedy mam do wyboru wyłącznie kanały w pasmie 5 GHz.

Jak to w zasadzie powinno być ustawione? Jak wybiorę AC zamiast N to widzę, że urządzenia na 2.4GHz do tego routera raczej się nie połączą ?

Odp: D-Link DIR-853 R1 - oba radia pracują na 5 GHz ?

w /etc/config/wireless zmień band z 5g na 2g, channel np. na 11 i htmode na HT40. Zapisz i tyle. W luci to pewnie ma jakieś swoje odzwierciedlenie.

Tu masz przykładowy config, żeby było okey luci ma z tym problem  ;-)
