I found the solution! When we got my PC it had bull guard installed on it as a trial but i didn't want bull guard cause it's crap. we got kaspersky instead but we installed kaspersky before uninstalling bull guard (or we didn't reboot after the uninstallation, etc etc, something like that). this is what was causing my computer to be unable to connect wirelessly! we had to restore the PC back to factory settings and uninstall bullguard properly. when that was done, i got my internet working just fine, no problems.

tl;dr: uninstall anti virus software properly before installing other antivirus software!
