There's some truth to this. My router is downstairs and while my ipad shows a strong signal the switch doesn't. As long as games don't lag I have no problems with it. I never experienced lag of any kind in MK8 but it's bad in SF but I barely play that game anyways. My pc is connected with powerline to the router and I dug up my old router and went on youtube and found out how to set it up as an access point. Works great. So I have the old router with external antennas set up as an access point through powerline and connected my switch to that. It sits like two meters from the router and the signal shows 100% but the signal test still shows very different results each time I run it. Sometimes it's better and sometimes it's worse than when running the test on the new wifi router downstairs. I've not noticed any difference in online play but it's loading the eshop a tiny bit quicker. That's funny. Poster above me suggested just what I've done. Lawl.
