    Weird vlan behavior with CTF enabled/disabled

    Ah! Only if I had read your post earlier today I wouldn't have spent two hours looking at this. At least my observation confirmed yours. Well for now I think I can live with that because other than initial configuration I probably won't be switching the same devices across vlans. Thanks.

You can use it as a dedicated sqm device, you can use it in client mode on 5ghz and rebroadcast...

    The Best PCI-E Adapter to Match R7800?

    In general if you need a usb/pci wifi adapter, it is usually a desktop computer. In such case I would recommend getting another r7800 and put it in client mode for three good reasons: 1) You get matching number of spatial streams thus getting as close to the advertised PHY rate as possible...
