My imac is in a area that would be nigh impossible to (cleanly) run a cat 5 cable to. I really could use some more bandwidth. Currently I am only getting 20mbps of the 50mbps I get at my fiber modem. I want to upgrade to 80211.ac. Has anybody tried the usb dongles? I wish someone would make a thunderbolt stick since it looks like that port will never be used. Also recommendations on routers would be appreciated. Not going airport, because they don't play nice with game systems.
