Zavedl jsem si pevnou síť 100 Mbps k notesu HP 620 a zjistil jsem, že mám problém se síťovkou
v dmesgu se mi objevuje:

Co se týče rychlostí, tak taky nedosahuju 100Mbps pouze např.: 3,81MB/s, i když na ostatních strojích dosáhnu plné rychlosti 10MB/s a na stejném notesu ve Widlích taky.
Vypadá to na problém v ovladači. Jiný kernel by nepomohl? V Koji si může člověk stáhnout a nainstaloval libovolnou verzi, která byla někdy pro Fedoru vytvořená.
