Hi, I wonder whether I could ask for a little tech support 
I'm having some internet connection issues and am trying to pinpoint the problem. There's an iMac hard-wired into a router, which gets a decent 13-14 Mbps. There's also an Airport Extreme (dual band) plugged into the router. Various MacBooks round the house get only around 3Mbps, and sometimes as low as 1Mbps. I'd normally put it down to a poor Airport connection, but usually the wireless icon is on 4 bars out of 4. I'm on 2.4GHz, 802.11n and have tried changing the channel. All doesn't seem to work.
Any suggestions would be great, because I thought it was the ISP's fault, but am starting to change my mind.
Thanks a lot in advance (It's amazing how dependent we are on the internet )
