I would suggest getting off that channel (2462). There's like 4 people using that in your area and you're most likely suffering from interference issues. You're at channel 11 (2462) and channel 1 (2412) looks pretty congested as well so pick a channel like 3, 4, 7, 8 or 10.

Do this through your wireless router settings.

Try to run a test against DSLReports.com and see if they measure an issue with the connection, preferably compare to a different computer also running on your network. This will diagnose if there is a genuine issue with the specific computer.

It's entirely possible there's some Wifi driver issue. Those problems do occur on occasion.
