Lately my desktop has been running slow when using Ethernet so I figured I should mess around with my router settings a little bit. When i enable 5ghz connection on my router my desktop has a lot better speeds and I get less lag. My problem is that my entire family uses iPhone 4's and I am the only using a Nokia 928 so, I pick up the 5ghz while they don't. I was wondering is there any router config or Iphone that would allow everyone to use 5ghz connection? Router Model: SBG6580
