Question about IBM ThinkPad T21 Notebook

IBM thinkpad T21

I have a IBM Thinkpad T21 with internet issues. When I first got this laptop, it had all types of driver issues, so naturally, I reloaded XP and hoped that would help. It did fix most of my problems. There was so much spyware before I reloaded xp, I dont know if it was able to connect to the internet before or not. Now, when I try a wired connection to the router, it recognizes that it's connected, but only sends packets, but doesn't receive any packets, I try to ping, and it pings the loopback address ok, but try pinging a and always get a cannot find host. Now when I try my brand new wireless card, its weird, sometimes it will see the 6-7 secured connections I can connect to, then 2 seconds later, it's like they all disappear and I have nothing to connect to, even after hitting refresh multiple times. I tried pinging and pinging and it also pings the loopback address ok, but last night, I kept trying to ping host, and it usually would get about a 75% return on the packets, then other times , just outright cannot find host. Any ides to help ? I'm open to anything at this point

Bad cable, bad network configuration or bad motherboard, in that order.
Try manual settings for the wired connection, do a repair and see what the comment is.
good luck

To my knowledge an IBM ThinkPad T21 originally was shipped out from the manufacturer without a WiFi networking interface, sorry.

Kind regards.

T21 Thinkpad will not boot up

you can boot it in safe mode (F8) then change the driver for the display adapter. If you give me a model and type #, I will locate these for you. Will look like 1234-UH7 on the bottom.
