Acquiring network address

From the PC you are trying to connect to your wireless router LAN there are two possible causes of these problem.

1. No DHCP Server Available.
2. You are using MAC Filters and the MAC is not defined in the router configuration.

Please verify this and you can easily get through it.

DHCP can be configured over your wireless router also incase you don't have DHCP Servers in your LAN / WAN. Other wise you can go for manual IP addresses.

Try the simple stuff first. I had this same problem and it ended up being that I had my caps lock pressed when I setup the WPA shared key on the router. I was entering the wrong key on the laptop because caps lock wasn't pressed. If you are using WPA security and you enter the wrong key, the behavior will be that it keeps trying to acquire a network address. In the system tray, the indicator "flashes" momentarily and then tries to reconnect.

The easiest way to see if it's a security problem is to momentarily switch to a different security protocol (WEP from WPA) or even disable security and see if you can connect (leave mac filtering on). If you can connect, it's a security issue and probably related to your key. Then turn mac filtering off (leaving security on)

if you need help configuring security or MAC filtering, check your router documentation.

Please Help Me: it just disconnect and shows not Limited connection, Not connected, when i troubleshoot it shows acquiring network address. so how can I solve the problems and how can I connect the wireless internet? Please help me. Plz how to configure the connection and 3com wireless setup.
pleae response me as soon as possible.

Thanks
