Setting up a 5 GHz only network with my AirPort Extreme
"I recently purchased a 21.5" Samsung monitor that is connected to my late 2009 13" 2.26GHz 8GB RAM MacBook Pro through a VGA connection with the VGA to Mini DisplayPort adaptor. Since I've started using it, my Internet connection has slowed to a crawl. I've researched the issue online and external monitors can apparently created wireless interference. I'm using a 2011 AirPort Extreme 802.11n/b/g. Is there anything I can do to eliminate this interference?"
I posted this at this link https://discussions.apple.com/thread/3912746?answerId=18254901022#18254901022&ac_cid=142432#18254901?ac_cid=142 432 and did receive an informative reply that led me to believe that my monitor currently broadcasts in the same wireless band that my MacBook Pro is reading on, in this case 2.4 GHz. I know the AirPort Extreme broadcasts in a 5 GHz band as well (which I thought I was, on all this time) and would prefer that my MBP read from that wave instead anyway (which should in turn solve my problem). I looked up how to do this and was told that by using AirPort Utility (version 6.0), and check to uniquely name the 5 GHz network, a separate 5 GHz only network should be created and selectabel under the Wi-Fi menu in the menu bar. I check this and restarted the router, but did not see the new network for the same router. I need to be able to force my MBP to read on the 5 GHz network since the 2.4 GHz network currently slows my internet connection to a crawl. Any advice on how to properly do this?
