Please test wireless in latest snapshots
-
I have upgraded to the latest RC1 snapshot, and the problem still continues. Once Access Point is enabled, ath0 changes MTU to 2290.
-
I decided to ask on the freebsd-net mailing list, and the response I got was, that 2290 is the default MTU for 802.11.
-
Any chance hostapd is resetting the MTU to 2290? I just looked at it's source code, and it appears that it may be setting it (see line 86), http://hostap.epitest.fi/hostapd/devel/hostapd_8h-source.html and (see line 241) http://hostap.epitest.fi/hostapd/devel/driver__bsd_8c-source.html.

weird… the last ifconfig we run on bringing up a wireless card is now 'mtu 1500'. My ath card hasn't shown this behavior in hostap mode, it's always shown 1500 without this recent change so it's not an issue with every ath card.
If anyone finds additional information on this please let us know. I'll be doing more wireless testing as time permits over the next week.

Ok heres the deal with me. (20080730-0226)
With no security It works fine, I get an IP address, With WEP It also works fine.
As soon as I enable WPA It will never connect. Even after I disable WPA and either choose no security or wep it still deos NOT work.
Can anyone else test with WEP or no security on initial install BEFORE enabling WPA to confirm it's the same with other hardware?
I have not had a chance to look at the MTU in this process, but if it does happen only when WPA get's turned on it may point us in the correct direction.

Many thanks,

mtu 2290 on ath0 and bridge0
-
THANK YOU!
ifconfig ath1 mtu 1500
ifconfig bridge0 destroy
ifconfig bridge create
ifconfig bridge0 addm ath1 addm axe0 up
(where axe0 is my LAN interface and ath1 is my Wireless (opt1) interface)Works perfectly!
NOTE If you do not have any security or WEP the MTU does not set itself to 2290 so wherever the problem it is, it's only when you enable WPA. Hopefully they can find the piece of code, or create some to set the interface MTU teardown the bridge and recreate!!
@JTY:
Did some testing, not sure if anyone found this before. Anyway…
After bridging the Wireless with the LAN, the following is appears when running dmesg:
bridge0: invalid MTU for re0
I checked the bridge0 interface, and it had an MTU of 2290, just like ath0. Obviosly that MTU is invalid for a standard ethernet NIC, thus it refuses to join bridge.
From there, I attempted to set ath0 (Wireless) MTU via pfSense webConfigurator, but the MTU setting was ignored. So, I manually set it via the shell. However, bridge0 still had an MTU of 2290 after changing ath0's MTU.
Finally, I decided to manually destroy bridge0, and recreate it. Now, that I had ath0 set with an MTU of 1500, both ath0 and re0 would have the same MTU.
ifconfig bridge0 destroy
ifconfig bridge create
ifconfig bridge0 addm ath0 addm re0 upAfter recreating the bridge with both devices having an MTU of 1500, the bridge worked properly. The only left was to create a firewall rule to allow traffic in on the Wireless interface, which I did via the webConfigurator.
Hopefully the above is of use to somebody.

Loaded the pfSense-Full-Update-1.2.1-RC1-20080804-0805
After reboot i had no OPT1 interface associated. I reqoqnize that one and went in and set the channel to 6 maually then it got associated (is was set as Auto by default). This the error found in log before i set the channel: kernel: ath0: unable to reset hardware; hal status 12. I have a feeling that WPA Pairwise cant be handle by any client. Is now set to TKIP mode now, which works for me.
The MTU is fixed now i think, all was at 1500 after reboot. Wireless client (WinXP) connected and I can surf from it. Thanks again for all your works for this GREAT firewall/router. Ill keep try updating to newer version whenever thare time for it and report back unsuall stuff from this machine and this newbie user :p
Wireless works …. wiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii :P
Oh anotherthing, when entering the Status\Traffic Graph, when graphic graph is showing, try click on Status\Traffic Graph again. Menu dont show fully.

Wireless is now working for me.

i hate to break the party but my wireless still wont work. mtu is 1500, security with wpa2/aes and i don't even see the wireless network in the list on my xp client. interface status for wireless says 'no carrier'

Goto "Interface" menu and try set your OPT1 channel manually (1-11), then goto Status+interface and check afterward if you still get no carrirer.

it worked, now i can see the wireless network from my laptop but i still can't conect. well it connects but pfsense wont give dhcp info to the laptop. setting static ip is not helping.
i can get dhcp info through stand alone ap connected to pfsense no peroblem though. -
I can confirm the same problem when bridging LAN and WiFi with 1.2.1-RC1 / built on Wed Aug 6.
My notebook is connected, but no DHCP lease. So I tried with static IP assignment, no ping…

same here. alix2c3, wistron cm9, wifi bridged to lan.
-
I'm running a build from the 10th, and no problems with wireless.
-
I run pfSense-Full-Update-1.2.1-RC1-20080810-1453, no problem with Wireless

Hi everybody,
I have still problem with bridging.
If LAN interface is down, WLAN won't work. If I plug ethernet cable, everything is working fine again!Hope that helps
Regards
-
This isnt a bug. This has always been that way.
If one interface of a bridge is down, the whole bridge will be down. -
Really, I never saw this problem with 1.2…
But I trust you. Any tips to avoid this (except plugging something ;))?
-
I'm not sure about 1.2
I only remember reading about it.
A quick search brought this post up: http://forum.pfsense.org/index.php/topic,2131.msg12397.html#msg12397Well you can always plug a dummy switch into it ;)
The only alternative i see is not to use a bridge and route :)
