Unable to get ip address when logging on to wireless network

I have a problem obtaining ip address via wireless on my laptop.
My pocket PC works on same wifi so I think the problem is the laptop.
Firewall is off. Same problem is present with 2 seperate usb wirelss dongles.
Any ideas

Known issue with some intel wireless modules. To establish proper commnication with som access points you need to change som driver settings.

Open  Wireless connection properties
Click Configure
Select the Advanced tab
Find the Wireless mode property, and set the value to match the network standard provided by your access point.
If you need access to other access points using other standards, experiment with this value but avoid the default 802.11a, 802.11b, 802.11g setting.
It might also be necessary to change the value of the Mixed mode protection property.
If you have an N-mode and/or 802.11h property, set them to disabled as well.

The problem is caused by different vendors using different draft standards.

Upgrading the firmware of your access point might also solve the problem.

Tried different wireless mode properties but still no ip. Forgot to mention that I can´t connect via my mobile anymore either and I´ve just tried plugging into a  LAN in internet cafe and the same problem arises.

The internet cafe problem is most likely caused by what seems like hardcoded DNS server addresses on your computer. You should change this back to the default Obtain DNS server address automatically.
 
If your mobile cant connect either the wireless access point is probably the culprit. Have you tried rebooting it?
 
It might also be worth testing a wired connection directly to the modem/router from your ISP.

I've checked the dns setings and both "obtain an ip address automatically" and "obtain DNS server address automatically" are checked on all "LAN or high speed internet" connections. Just to clarify the mobile phone status, I can get online directly on the phone or with a pocket pc with the phone via bluetooth but not using the pc. I am on the move at the moment using free wifi hotspots so am unable to reset any of those. Thanks

What antivirus/firewall do you use?
Some firewall/antivrus packages have a tendency to suddenly block the network adapters. Try disabling the firewall and see if that helps.

Try removing avg completely to check if it has somehow blocked connections.
Make sure you have the necessary files and license keys to reinstall
