gigabit mini pcie wifi card with AP mode

  • 772

I set up a DIY router years back using a fitlet i "barebones" mini PC with a mini PCIe intel 7260 wifi card (using the iwlwifi driver) running in AP mode (bridged to the ethernet coming in from my cable modem). lots of hacks to get it to function including WPA supplicant, hostapd, etc.

unfortunately, even after lots of trial and error to get this card to work, I could never get it to function above 54mbps even though it says it's a 5ghz "dual band" card (seems 5ghz AC is only supported in client mode, and it only has one radio). this worked fine for slow 100mbps cable internet.

but I recently discovered I now have symmetric gigabit internet offered in my neighborhood and signed up.

what are my options for faster mini PCIe wifi AP adapter supported on ubuntu? is there such a thing? even 100mbps would be nice, but gigabit wifi would be awesome. alternatively, if there's a way to force the faster speed for AP mode on my current card, I'd be thrilled.
