Assalamualaikum all,
Hope you all are doing well. I am experiencing a problem at my work with the wifi connection. Whenever I try to connect my laptop (having win xp) it says certificate cannot log you on .. (probably because they have win 7 and wpa2-psk). The Computer man told me to upgrade my laptop to win 7 but I do not want to get on win 7 nor i can buy a new laptop..
Could anyone of you please let me know what should I do to troubleshoot the above said problem?

Regards.
