      Hello all,
      i bought an Mikrotik R52H mini PCI yesterday (Atheros AR5414) and installed it in my Thecus mini-PC. The card was recognized by pfsense (1.2.1) and i set it to AP mode with WPA encryption bridged to LAN. Everything went well until i decided to connect with a laptop. I got an IP from DHCP, was browsing for 5 seconds then my connection dropped. There was no response from pfsense even on my desktop PC with a cable, switched VGA cable and keyboard to pfsense box but only the startup menu on the display, no response to my commands from the keyboard also - totally frozen. Then i restarted pfsense and it was working for 1 minute again. Disabled the wireless interface after this…
      Does anyone have an idea what may cause this behaviour?

          SOLVED: it seems that all mini-pci wireless adapters are evolving a lot of heat. Unfortunately my baseboard design is not very good and the mini-pci wifi stays on top of the chipset. The chipset gets overheated and OS crashes….Disabled the wifi for now.

            Im having the same symptoms, but am slow to accept over heating. My pfsense box is PIII atx case.

            The atheros wifi is mini-pci on a mini-pci to pci adapter.
            PFS is 1.2.1

            Everything works fine if the wireless ap (opt1) is on its own network and no bridge, but when i bridge to LAN PFS freezes in ~2min. On restart it works again… for ~2min, just long enough to remove the bridge to avoid further freezing. I have tried this several times - bridgeing opt1 with lan freezes PFS.

            By freezing, i can not ssh, ping, or load the web gui.

            At my home, I want WLAN to have the same services (not just DHCP, but zeroconf, RDP, SSH... everything.) Do I misunderstand the purpose of the bridge?

            thanks, tom

              Wifi and shared IRQ is usually a very bad combo. Can you try to move the card around in different slots ?

                  My wifi works for days in bridge mode, but eventualy no wireless clients can connect, stuck at authentication. When I don't use the bridge everything keeps working fine.
