I'm currently running a G73JH at work, using a AWUS036NH Alfa external wifi booster. Everything was fun up until a weak ago, when my internet speed suddenly plummeted to nowhere. Usually I would get around 100kbps on the download using a unsecured network at work, but now it's down to 5 or 6 kbps. My coworkers that are not even 300 feet away are getting the usual 100lbps speed, but not me. It's a continuous four bar signal, so the signal strength is there. I updated all my wifi drivers, including uninstalling and reinstalling the Atheros drivers.
However, since the antenna runs off its own wifi adapter (it's listed as 802.11g USB Adapter 2 under network in device manager) I'm not even sure it's running off the laptops adapter anymore. I've literally tried everything me and another computer savvy friend could think of. I'm beginning to think it's the antenna, but I don't want to risk getting a mobile hotspot and paying $200 odd just to find out it's the laptop in the end and the antenna was fine.
Has anyone else had this issue? Is there anything I can do to make my speed back up to where it was?
