oZ, what router are you using? I've found several references to people haivng this problem with vertain Linksysrouters. I also had a similar problem a while back (too long ago to remember the error message though) that was caused by my router. Check the firmware version of your router and see if it is the most current one available. If it isn't, try updating the firmware. If it is, try rolling it back to a previous version (this is what worked in my case).
