Subject: [OS2Wireless] XWLAN Bugfix Release V1.11 for DHCP problems

Is your AP beaconing, or do you have SSID broadcast turned off? Without 
the beacon, you'll need to specify an SSID in the profile.

Interesting. What do the following say, before you issue the DHCPSTRT:

IFCONFIG LAN0
IFCONFIG LAN1

Hmmm... I started drafting this message at 3:30 this afternoon. I held 
off finishing it until I had a chance to experiment. I do see your 
problem, or something similar, I should say. There definitely is 
something odd happening with a second card.

In my setup, my wired interface is LAN0, Cisco is LAN1, and IBM High 
Rate LAN2. I can switch cards back and forth, select the appropriate 
device and adapter number in XWLAN, and leaving the pr0ofile alone, 
reassociate with the AP and get an IP for the alternate card. However, 
if I switch to hotspot mode, I can't find anything with LAN2, and 
telling XWLAN to scan for connections with LAN2 resulted in the CPU 
hanging at 60+%, until I pulled the card (at which point the CPU meter 
dropped back down to 2%).

What do you have in LANTRAN.LOG for your setup? Try cranking up the 
debug level in PROTOCOL.INI for the Wi-Fi drivers, so we can see what's 
going on.

Neil, do you possibly have the option set to reuse the last leased 
address if a DHCP server cannot be found? I've had some trouble with 
this on a couple machines, namely, my wife's. I've had to manually go in 
and request a new lease, even though it appeared that I had a valid IP 
address. Check %ETC%\DHCPCD.CFG for the "previousCFG" parameter, and 
comment in out.
