Linksys WRT150n Wireless Router Laptop with NetGear Wireless Card cannot get IP address - Wireless Routers - Linksys Community Forums
Dell Inspiron 6000 computer running Windows XP.
Netgear WG511T 108mbps wireless PC card.
This combination has worked fine for three weeks.
Suddenly windows cannot connect to the wireless network because there is an "invalid IP address".
Actually the icon says it's connected.
It is stuck at "acquiring network address".
I have spent all day with Linksys support who could not help.
I have uninstalled the network card and reinstalled.
I started by reseting the router and the cable modem.
The wired part of the network works fine.
Thanks if anyone can help.
Oh...using WPA security.

Hi, Does your wireless card have N capability?
If it does, you can try to change the security to wpa2-personal-AES and set the radio band to wide and you can play with the channels.
Give it a shot and hope it works!

Linksys support had me take security completely away yesterday.
Laptop still did not connect to my vulnerable network with a "very strong" signal.
They then had me enter a static ip address, submask, and DNS addresses.
The tray icon said it was connected but I got a dialog box asking me to pick a connection.
The choices were my two dialup connections.
And even though it said "connected", when I clicked on my email client or browser it didn't work.
After researching this a.m.
I just tried ipconfig/release and ipconfig/renew in the cmd.
The prompt returned that ip was already released and then that it could not renew because it could not contact the DHCP server.
The only other time this happened I stumbled onto the fix that if I followed the procedure to add a computer (plug into the wired network,go to linksysfix.com/ela, download, run) and unplug from the wired network the wireless works.
The laptop shows up on the network as a duplicate computer with a new MAC address.
Hope this added detail helps to diagnose.
Thanks.

Does this laptop work anywhere else with some other wireless network?
And do you have any other wireless computer working?
Also you can update firmware of router, you can get it from www.linksys.com/download, and also update drivers of wireless adapter to latest version.
And make sure all firewalls are disabled on laptop.

Yes the laptop connected on vacation to the various hotel networks.
I will recheck locally today.
I am running the latest firmware and the latest driver on the network adapter and the firewall was disabled.

If your latop is working fine in other networks ...only one option left is changing few settings in router wireless settings ....

Thanks for trying.
I went to Panera this afternoon.
Was able to connect to their unsecure network using the Netgear adapter card.
Came home tried with no success to connect.
Input your changes and tried again.
Back to "acquiring network address" and "invalid IP address".

In such case if you already checked the Laptop working in any other network ....
& also you had tried all the settings as i mentioned in previous post ....
The only onr option left is to reflash/upgrade the firmware of the router ....
If still the Laptop is not online ...
Maight be possible the router is gone bad ...
