I have just moved to a new house with wireless internet. On one computer I have managed to get attached to the wireless connection without any trouble. On the other one (also an IBM Thinkpad)I can't. It detects the network, asks me for my password, and when I put that it responds by saying that it can't find a certificate to connect me. The wireless connection button at bottom right indicates that the wireless internet connection of "off" but does nothing when I try to turn it on.
I've tried to use the IBM restore programme, but its buttons don't respond at all--in fact only part of the page comes up. So I suspect that I have some malware. The problem is that all fixes I have seen involve downloading programmes. But if one's internet connection is the problem, what does one do? I have run Malware Malbytes, and it shows no infections. I do have Erunt loaded on the computer.
