Otherwise I'd be happy to know where else I should report this problem. So my university is running a dual band eduroam wifi. When the signal is rather weak, I get frequent timeouts for my network connections (even though my network manager will report that I am still connected). When I force my wifi card to stay on the 2.4 GHz network, everything works fine. But I usually want to use 5GHz and benefit from the higher transmission rate, so toggling that manually is just an ugly workaround. Seemingly the driver makes it connect to the 5 GHz band, even if the signal quality is so bad there that the transmission rate is worse and/or the connection breaks down frequently (because naturally, 5 GHz networks have more signal loss over distance). I have no idea how iwlwifi and wpa_supplicant work internally, so maybe I am missing some vital option there? My card is an Intel 6300 Ultimate AGN, and I've tried different network managers (currently on wicd) but get the same problem everywhere. Cheers, Natanji
