The problem is not in wpa_supplicant at all. 

I guess, you have a wireless keyboard and mouse. The problem is that the 2.4Ghz wireless key/mouse work on same frequencies as Wi-Fi b/g standarts. So, when you use you wi-fi channel at high speed (for example, when downloading something) - the wi-fi connection between you AP and PC interfere with wireless key/mouse. That's why you have freezes and repeated characters. This is normal. I have the same problem with my Logitech MK-520 when downloading something big and time-consumable via Wi-Fi, but this behavior does not appears when, for example, surfing web sites or playing online games.

You can try to move you AP further from you wireless key/mouse. Maybe this can help. Or... throw out your wireless key/mouse and use wired instead.
