Wireless PCI adapter card problems

Hi all- I hope all here are well. Very informative forum. I'm a wireless newbie, & I know enough to be dangerous! ;-)

I'm running Win2000 Pro. I bought an inexpensive Trendnet TEW-443PI wireless PCI adapter card last week. It installed fine & worked great with zero problems for several days. I went away for a few days & now I can't get any internet data transfer. When I start an internet app, the modem starts dialing instead of connecting thru the wireless card. The computer was on while I was away, but no one had access to it. The wireless card was off, & I was D/Ling with the modem & D/L mgr unattended while I was away.
The access point is unsecured, and the adapter card's config utility shows a good quality connection and high signal strength.
I have rooted around in numerous forums, followed tips from the Trendnet site, and played with the Win2000 network settings.No joy.

I see some problems with missing entries & features disabled, but do not know where to get the IP information or change the settings to enable the required features to correct the problem.

I would greatly appreciate any suggestions. I really got spoiled for the few days I had the use of the high speed connection.

Take care all,

first, use the Device Manager to disable the modem; stops the dialingout.

you say it worked ... you have your OWN wireless router?

the ip-address 169.254.168.233 says your adaptor did not find the router and
could NOT make a DHCP request to it.

disable your wireless adaptor,
restart your router; pull the power plug, wait 30 sec and then plug it back in.
wait one minute and then enable your wireless adaptor.

use run->cmd /k ipconfig /all to monitor the results.

if that doesn't work, the next step is to RESET the router and start again
at disable your wireless
