|To be honest, it might make things worse.|
Considering this is the only computer having this issue, that tells me the problem is the computer. Before I uninstalled/reinstalled the NIC I would try another wireless NIC if at all possible. This would be the best way to figure out if it's your NIC or not.
If the same issue happens with a different, known to be good, wireless NIC, then it would have to be a software issue and that might mean the operating system. In that case, and only in that case would I try the un/reinstall of the NIC. If that didn't work, you'd be down to reinstalling your operating system from scratch after wiping the computer.
Do try another wireless NIC first if at all possible.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
