I recently bought a USB Dongle with frequencies from 2.4 to high 5 GHz to use with my Raspberry Pi.
Previously I used another USB Wifi Dongle with the only frequency of 2.4 Ghz, perfectly working with some not so expensive ( in terms of hardware resources) games, just some lags or freezes sometimes for a few seconds, while some "heavy" games like Far Cry 4 were laggy and unplayable.
I plugged the Dongle into my Raspberry Pi, and after a little bit of setup, I encountered a very bad performance for my Dongle, both in 2.4 GHz and 5 GHz. The previous dongle seems to work FAR better than this one, even if it's sold as an enhanced version. Not only this, but also it gives me serious problems while I code in bash.
Quick Question: Am I doing something wrong? Is there any other check I can do or should I consider returning?
