Wireless only works in safe mode

Safe Mode disables most drivers and Malware... my guess is your system is infected specifically the TCP stack... Start in Safe Mode with Networking and do an Online Virus Scan,

No viruses detected, I used 1 online scan and also comodo and spybot, nothing.

Post the output from ipconfig/all here when your computer is in Safe Mode & Normal Mode.

It is like this on both connections but in normal mode it disconnects after a few mins sometimes.

I turned off SKype's port 80, could that be it?
Not sure why it would have worked before and not now though.

If it blocks again, I am going to try a netstat -aon and compare the PID with the PIDs in the task manager.

Your ipconfig /all results, specifically DNS Server and Lease acquisition - expiration date, show your computer is connected to the internet, the problem may be Winsock corruption.. to repair it Download "XP TCP/IP Repair 2.1" from http://www.xp-smoker.com/freeware.html.

Use the TCP/IP reset button and restart the computer... and next use the Repair Winsock button and restart the computer again.

As far as I know, port 80 is the default port for Internet Browsers, so it's possible that caused your problem. Enable port 80 and assign another port number for Skype in the Windows Firewall.

Stopped working again.
However, nothing seems to be bound to localhost:80.
Email works though.
Any ideas?

E-mail through an email client? (Outlook, Outlook Express, Thunderbird?)... the difference between Internet Browsers and Email Clients are the ports they use to connect to the Internet. Have you added an exception for port 80 in the Firewall?

Default Ports for Email Clients: Pop, Imap, w/wo SSL
