I have a Laptop (Dell Inspiron 4150) with a wireless B/G minipci card (Intel Pro 2200BG). When running DHCP on my home wireless network I always get "Limited or no connectivity" and no connection. If I set it up to static IP I have a good 54mbps connection immidiatly. I have another laptop which have no problem getting a IP adress over DHCP, so my router, firewall, switch setup should be ok. I have installed the Microsoft Fix KB884020. I have run the winsockxpfic I have checked for spyway, TSR programs using AdAware I have tried the ipconfig /release; ipconfig /renew Still no connection using DHCP. I just get a 169.244.XXX.XXX adress, which I guess windows defaults to if no DHCP is availible. Please help me !!! THX

Have you tried to hard wire the laptop in with a network cable. If you get an ip address you may have a setting in your router that only allows a certain mac address to connect to the wireless network. If wep was enabled it would ask for a password so I don't believe that this is the problem. Can you see your wireless network when you have a limited connection (checking available wireless networks). Also what type of router are you using. John Cambece

When I am on a cable there is no problem, good 100mbps connection. When I get the "Limited or no connectivity" sign, I have no connection ie. 100% packet loss. I use WPA encryption, which again works seamlessly with static ip's, so I don't think the problem is here

Well it sound like one of two things, it is either your router config or your laptop wireless card. Since the wireless card works when you give it a static address I would have to say it is something with your router. Maybe try removing all of the wireless security and see if that works and then reconfigure the router. John Cambece

So today I tried the following: Removed a lot of networking software from the PC (Zonealarm, Hamachi, etc) Ran the software patches and fixes again: No connection Turned off the Windows XP firewall: No connection Reloaded the Router Firmware: No connection netsh int ip reset [log_file_name]: No connection Disabled WPA encryption: DHCP CONNECTION !!! Enabled WPA encryption again with another key: DHCP CONNECTION !!! Enabled MAC Adress Filterring: DHCP CONNECTION !!! So now everything seams to be working. I have transfered more than 6 GB over the connection and it is still going strong. I belive it was a mix of things causing this problem, but now I don't really care
