So i'm using a Desktop USB wifi adapter and when i first bought it Early this month (September 1st) it was working great, my speeds normally averaged 1mb/s on steam and regular downloads. Youtube was blistering quick with no stop/pauses to buffer. Since a week and a half ago it suddenly slowed to a crawl. CSS ping is abysmal ranging between 400-900 at all times. Youtube is a pain now to watch and downloads regularly are only 3 kb/s to the highest at 70ish kb/s.
I downloaded a driver for my adapter from the company and it shows alot more data about my connection such as link quality and throughput. My quality is hovering around 88-mid 90's. The router is only 20ish feet away and travels through only one wall and one wall of glass. My signal strength is thus always very good or excellent. I've tried every USB port, poking around every setting, googled my way everywhere over the past week and a half and got no where. I'm started to think my adapter is kicking the can since it's a cheap Tenda adapter.
I doubt that the provider is throttling. It's a more business catered provider called Paetec Communications according to speedtest. Another thing worth noting is that my ping on speedtest (although i know it's not fully accurate) is always stupid high even in my home server city.
Any thoughts? I'm running XP
