I have an issue with wifi where my office is located in my basement. My main computer is ethernet hardlined to a 4 port switch which is run to my wireless router upstairs but my other wireless devices have a very poor connection. Is there a particular device that i can buy to plug into my 4port ethernet switch to put a wireless connection in my office? The solution is probably very simple I just don't know exactly the proper device to do this. Any links to any products on amazon would be super helpful too. Thanks folks.
