My wireless adapter is not getting full WiFi speeds.

[Arodjom]

Hello, I have a Cirago WiFi & Bluetooth Combo USB Adapter to allow my desktop to have wireless capabilities. I have had it for a few months now and it was working perfectly, but just recently, it started to become very slow. I pay for a 15 Mb/s down and 2 Mb/s up plan. All of my other devices (Laptop, Smartphone, Xbox) get the expected speed, but my desktop does not. It just randomly stopped getting the expected speed and now does not exceed 1-3 Mb/s. These devices are all located in the same room so its not a bad connection. I have tried uninstalling and re installing the driver, but still no luck. The driver was also updated to a more current one, but it still did not work. Any suggestions???

What 802.11 instruction does it have? (e.g. a, b, g, n, ac)

My entire network is 802.11n and so is the adapter.

802.11n is old, and only receives up to 18.75 Megabytes, and only at some circumstances.

I know its old but that doesn't answer my question. I have never had a problem, within the 5 years I have had 15 mb/s internet, with receiving the full speed. All of my other devices get the full speed besides the desktop, which just recently stopped getting the full speed.

Go to task manager and check what's using up the network.

I just checked Task Manager, and there is absolutely nothing using my Network. It's at 0%. I would like to add a side note that I did plug this adapter into another computer, and installed the exact same drivers. I then tested the speed from the same spot my desktop was having issues at, and I received 15 Mb/s like it's supposed to. I then plugged it into my desktop again and it only got 1-3 Mb/s. Could this be something in the network settings? I wouldn't think so because I assume uninstalling and reinstalling the drivers reverts the settings back to default, right?

Install Windows to a new hard drive and see what happens. If it works, something about the card. If not, your system seems a bit tired.

Unfortunately I do not have a spare hard drive at the moment, so I cannot try that. I wouldn't think it would be windows because I just reinstalled it a month the ago when I got a new motherboard, but I don't know.

Shrinking you hard drive by 20 GB would also work. (e.g.: 60 GB partition to 40 GB)
