help-wireless connection problem

​Good evening all,​

​I have a dell 4550 running xp home and connect to the internet using a DLink DCM-200 cable modem, Linksys wireless access point router (model BEFW11S4) v2, and a wireless Linksys WMP11 card v2.7. I also have a older dell running win 98 and connected directly to the router with a ethernet card. The older direct connect computer is working fine for the age.​

​The XP machine started having problems about 4 days ago when my son decided to move his older computer, modem, and router upstairs. He then moved it back and that is when the problems started. Again his works fine, the cable modem works fine, the router works fine, the wireless card works fine, everything works but my www connection. At first I could get on the www, but it would loose connection, then reconnect, all the time, very annoying. I tried connecting directly to the XP machine and that worked fine also so I started trouble shooting the XP machine. A day or so I lost all access to the www, even connecting with the LAN wire.​

​I have signal, but no www. This is what I have done so far. As stated I trouble shot all kinds of things on my own, I even got out the manuals (wow) for the router and cards. I have uninstalled, reinstalled the drivers, removed the wireless card, reinstalled, disconnected the modem and router and reconnected the way it is supposed to be done in proper order. Nothing worked so I called the cable company to make sure. They actually helped me quite a bit, tried some different Pings and finnaly stated the IP address was 169.??? and that is not good, they tried to get it changed, but could not do it. Finally it was out of their hands, the cable was working. Then I messed around some more and called Linksys today. Again, they were pretty helpfull, tried all kinds of things again. They pinged and panged and then they changed the IP address to something like 192.??? by not obtaining an IP address automatically. Still no www, they called upstairs for a supervisor who spent more time doing a lot of the same things. Changed all the chanels on the router, moved the router further away, made sure I did not have cordless phone near by. Pretty much everything that could be done. Finally they said it has to do with the TCP IP something or other and I needed to call Microsoft (yeah right) or the manufacturer.​

​So that is where I am at Guru's. I beg for your assistance to this very annoying thing. I have read the frequent questions and read a lot of different posts. I see a lot of post that are very related to this and you have been able to correct some of them. This seems like a common problem that happens.​

​Thanks in advance.​
