Hope this link help your concern
I have AT&T as my ISP, which means all 4 cable boxes are using the bandwidth, Also with 3 kids I have a combination of 6 tablets and phones sucking up the Wifi as well. Additionally to that I have 2 computers and my sons Playstation. My question is whether or not it is most practical to wire as many devises as possible or just let the majority use WiFi? Since the wired devices receive higher bandwidth will that take away from each other or lower the wifi?
I hope this makes sense, I was wondering about it at work today so I'm typing it in a 4 inch window trying to hide it from boss man.
