I have a problem connecting an aquired old dell WXP laptop to my home wifi. It detects the network ok but when I try to type in the password/ ID it just makes a bong noise I refuses the type.(Yes I disabled the firewall.) I've connected other laptops with no problems but I think I must have forgotten what I did. Main PC on W7.
It might be ingrained on a bios chip. Your best bet is to note the lappies specifications and product number etc. and join a Dell forum or contact Dell themselves. email support Dell, your problem is low priority I guess so give them an email, with as much facts about the lappy, as possible. Good luck.
