Hello, I have been having an issue with a wireless adapter I recently purchased. I have a TL-WDN4800 which seemed to be broken. after wasting an hour trying to get it to work I learned that it was not my card, but my router that was the problem. I was able to use my mobile hotspot on my tablet while it was next to my router, so I don't think that it is an issue with distance. I think that it is a problem with the type of connection but I'm not entirely sure. Any help is much appreciated.
