Bug: Wireless Atheros 5212 chip - ath0 mtu 2290

Hareide

Bug: Atheros chip is forced to mtu 2290?

Been running pfsense 1.2.2 without any problems. My setup looks like this:
WAN
LAN
WIFI

WIFI ssid; qwe
WIFI in AP mode
Bridge LAN-WIFI
Firewall rule to allow all traffic from WIFI to LAN (using dhcp from LAN interface)

Today I tried to port my setup to the 2.0 Alpha. I used this image (booted from cd, made simple install):
pfSense-2.0-ALPHA-ALPHA-20090919-0102.iso
I only added WAN and LAN interfaces during install.

GUI:
When I try to add my wireless card it seemse like everything is okey. And i prossede to make the bridge. Everything seems fine (No errors from the gui atleast)

But I cant find the wireless AP when I try to connect with my laptop. Sometimes a ssid:linksys with full strength comes along, but dissapear if I refresh the list (pretty sure this is the pfsense wifi card, prob a bug in the device driver or when the interface is beeing brought back after reconfig?).

Status -> Interfaces:
WIFI interface (ath0)
Status no carrier
MAC address 00:13:f7:3d:17:52
Media autoselect
In/out packets 0/0 (0 bytes/0 bytes)

In/out packets (block) 0/0 (0 bytes/0 bytes)

Bridge (bridge0) learning

When bridging LAN and OPT1 i get this message in console:
:bridge0: Ethernet address: 0a:26:b1:96:8b:69
bridge0: illegal mtu for ath0

And ifconfig show me that the mtu us 2290 (which is strange?)

One last thing that I have noticed:
GUI -> Interfaces -> WIFI:
Standard: (its blank, cant choose anything! In 1.2.2 it was 802.11b, 802.11g and 802.11g Turbo)
Channel: Auto (this is the only available option, in 1.2.2 I have 12 options, and "Channel 6 - Turbo".

Not sure what to make of this, and Im changing back to 1.2.2 for now.

–----------------------------------------------
From 1.2.2, up and running without problems

Wireless is sort of crazy in 2.0 right now anyhow, it's about to be overhauled once things get going on FreeBSD 8.0.

This same bug was fixed in 1.2.3, not sure if the fix was also done on 2.0 or what.

Here is the other thread where the bug was found/fixed in 1.2.3:

The bug is not present in: pfSense-Full-Update-1.2.3-20090919-1549.tgz

cmb

That was fixed in 1.2.3 but not in 2.0 since the wireless in 2.0 will be going through a major overhaul to support FreeBSD 8.
