Hi,
Thanks for all the help. I have partially fixed the problem but things are not working great. But they are working now, which is something.
Here are some of the things which I did:
- I uninstalled Net magic software.
- I changed the channel (?) on the router. I noticed my laptop was going down whenever I used the cordless phone to try to get help to get things working.
- I lowered the security on the network from WPA to WEP. I am a little concerned about this but this got the desktop (with XP) onto the network
- I turned off MAC filtering
Problems I am still having:
- I think my security is too low and I would like to beef it up but I am still a little clueless about what I should do.
- The desktop connection is hinky. It does not stay up all the time. I have to reboot. I am trying to get files copied from the desktop to the laptop and the connection fails in the middle of the copy and I often have to reboot.
- HP chat (worse than useless) had me uninstall IE. I use firefox so this is not my biggest problem, but it has caused other issues and error messages.
- I also spoke to the folks at Dlink. They said the new router was broken and I would have to return it. (This was before we figured out the channel fix.) They would not accept a return until 30 days had past. I could not return it to the store since it was circuit city and they are not accepting returns. Dlink said the only solution was to wait the 30 days

This is a messed up policy.
So we did some checking and learned about the channel problem and noticed that when we were on the phone with the laptop connection would fail but as soon as we hung up it would work again. We put two and two together then called dlink and they said "oh yeah, that could be it"
Let me know if you have any ideas about these additional/new problems. Thanks again for all your help so far.
