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.

I have a mini PC with dual nic and wifi setup to act as a router

my setup:

WAN port (enp2s0) -> cable modem

LAN port (enp3s0) -> gig switch

LAN and wifi are bridged to create "br0" which has a static IP of 10.1.10.1 mask 255.255.255.0 bcast 10.1.10.255 net 10.1.10.0

and br0 is assigned as the main adapter for DHCP to listen on

my wired PC can connect to the internet no problem! works great. DHCP server on the box assigns all the settings correctly.

I try to use hostapd to launch the wifi (sudo hostapd /etc/hostapd/hostapd.conf)... it acts as if it's working (reports AP-ENABLED and I see the network on wireless devices) but I can't connect -- either with WPA encryption on or off.

basically the device connects/disconnects over and over. never getting an IP address.

here's my TCP dump for the wifi adapter (wlp1s0) http://pastebin.com/ci24bfXP

here's my /etc/hostapd/hostapd.conf http://pastebin.com/WTz1v3Qp

wifi device is "Intel Corporation Wireless 7260 (rev 73)" using iwlwifi

rfkill lists NO

tried killall wpa_supplicant

here's my dmesg dump after trying to launch the AP http://pastebin.com/q3VxpRUv
