ath9k Does Not Pass Through DHCP When in Master Mode
Last modified: 2009-06-10 12:48:58 EDT
When connecting Windows (XP/Vista) wireless clients to a hostapd AP using the ath9k driver, DHCP
offers do not succeed. When setting the network interface settings on the
client to use a static configuration connectivity succeeds and client
networking through the AP functions well.
A high-level layout of my network is as follows:
- Linux router running hostapd: 192.168.8.1
- Windows Server 2003 DC running DHCP: 192.168.8.20
- Windows XP/Vista clients
Following are details of the router running hostapd:
- Bridge interface: br0
- Interfaces attached to the bridge: wlan0, eth1
- Bridge IP: 192.168.8.1
DHCP is working and the bridge functions: I have confirmed this by
obtaining a DHCP lease via the notebook's LAN port.
I am using the following software versions:
- hostapd 0.6.9
Following are the contents of my hostapd.conf file:
Is there a setting that must be added to allow DHCP to pass
through the bridge. UDP works fine through the bridge, as the client can see the
Windows domain and can broadcast for clients on the domain (when connected
via a static IP or via a physical LAN cable).
Can you please try wireless-testing
I upgraded my Kernel to 126.96.36.199-52.fc10.i686 and installed an AR5416 card and DHCP now passes through fine.
Thanks, John can this be closed
