My wireless n modem router with 4 ethernet ports is on the ground floor at the front of house (thick walls, doors, etc) near the BT socket. Previously I ran 15m network cable up 2 floors to the loft (office) for the main PC, as wireless is available, but pretty poor. I now want improve wireless availability in the loft and to extend the network coverage out to the shed at the bottom of the garden. I was thinking of a wireless access point with built in 5 port switch as the best solution? - that would certainly improve the wireless in the loft no problem, but if I chose one with a detatchable aerial, and replace with higher gain version I'd have more chance of reaching bottom of the garden? Also, I presume I would connect the 1 network cable (from the router) to the AP and I could then also connect the PC to the AP via short network cable, as well as having the wireless for other devices?
I am not sure if I have to go into any complicated aspects of the router or Ap configuration to do this?
Any advice/correction would be most helpful.
