Temat: Wyłączone kanały
Cześć, mam na TL-WDR3600 wgrane OpenWrt 18.06-SNAPSHOT r7405-06a20afb34 z LuCI. Zasięg jest ok, ale przypadkowo trafiłem na ten temat:
https://eko.one.pl/forum/viewtopic.php?id=8793
Przewija się tam komenda iw list. Wpisałem ją u siebie i zastanawiam się dlaczego ostatnie kanały są wyłączone, choć sam ich nie wyłączałem. Może mi ktoś to wyjaśnić i powiedzieć jak te kanały włączyć?
