I want to connect up my small flat so I can use any device I want, anywhere, reliably. My MBA runs and connects to my wireless router which is next to the PC in the living room, but the signal is poor - keep dropping out. I intend to keep the PC, at least for a while ( £££ ) and I have the common UK broadband setup where the signal comes down the twisted pair telephone cable to a proprietary router / modem, a NETGEAR N150 from Orange, which is USB-plugged into the PC. At least some of the system software and setup has to be stored / done on the PC, but when it is setup and running I can connect wirelessly with the MBA while the PC is off, and have cabled network links into the TV and so on. I'm sure I could get an Airport Express and just put a network lead from it into the proprietary router, then use it to get a better wireless signal at the MBA when I'm using it remotely, but I'd rather like to use an Airport Express or Extreme and try to get rid of the proprietary router, with a view to network cabling everything in the living room and getting a decent wireless connection through the rest of the flat. Any thoughts? - buy the Express and just hard wire it ( Apple Store is one mile away and has a couple of dozen on the shelf ... ) or does anyone have any experience with setting up Express / Extreme to take the place of the proprietary router.
