laptop internet connection issues?

[322]

All I can tell yoou about this computer is that it's an msi a5000 laptop running XP on our wireless service with an internal internet card. my battery died earlier and I all of a sudden couldn't pick up internet connection, i installed a wireless adapter that connects thru a usb port and it's picking it up now (albiet slowly) and when i disconnect i have to uninstall and re-install the product to make it work again. I ran norton, it didn't find anything, but sometimes it says "the host file is corrupt" and it' can't fix it. I tried recovery to a several days ago and that didn't work either. I have also reset the router and internet - didn't work. What should I try to fix this problem?

Would suggest you connect wired to the router using a cat 5 Ethernet cable and ping the IP/TCP address: How to Ping an IP Address ; http://www.ehow.com/video_4978447_ping-ip-address.html

The wireless USB adapter should work and you should not have to uninstall or reinstall the adapter software this would be a set up problem, check your settings and set up buy reading the user guide on the software CD for using and setting up the wireless USB adapter.
