ORINOCO WIRELESS AND TCP?IP

[Darrly]

Hi there,

I have an IBM netvista pc installed with Orinoco wireless
lan card accessing Cisco 350 AP.
The PC configuration is P4 2.4GH with 256MB ram. Running
on Window 2000 Pro and on service pack 4.

Have a problem with the wireless connection. Sometimes,
the connection is lost even though there is radio
connection. As the problem is not consistant, it make
troubleshooting difficult.

From event log, only can see "No domain controller found."
There is once, I have found that the static IP set has
switched to DHCP. I have failed to change the IP address
back to its static address. Everytime it will reboot after
setting the static IP address, the option check is DHCP. I
have resolved by deleting the TCP/IP protocol and
reinstalling it again to temporary resolve this issue.

At times when the network connection is lost, I need to
resolved through rebooting the PC several times before
able to reconnecting to the network.

I have checked out with Orinoco and IBM on this issue. The
problem still persist after upgrading the BIOS, change
motherboard, running additional setup to edit the registry
which is recommended by Orinoco.

Please advise what could be the possible caused and what I
can do to resolve the problem.

Thank you very much.

Best regards.

The IP stack functions outside the wireless networking card. So for
instance, if the client was slow to get the wireless connection active the
DHCP Client would time out and you would get an autonetted address. If you
statically configure the ip on the nic, then this takes out of the potential
problems. You still have the root issue of why is the link taking so long to
get active.

I would double check the nic drivers and access point config etc. Alot of
times you can disable the security on the access point as a test to make
sure everything function then build the security back up layer by layer.
