I would like to connect 3 Access Points to my LAN. They are all wired together.

Question:

  • Do I use the same SSID?
  • If I use the same SSID, do I put them on the same/different Channel?
  • Are Network Adapters supposed to automatically switch AP when they move into range of a stronger one? Does choice of SSID/Channel play a role in this?

  • Yes, if you want people to be able to use the nearest transparently
  • No, you must ensure the channels don't overlap
  • Yes and yes/no

In summary, if you want to use multiple APs on a network and have people roam between them without having to know or care about their being multiple APs then you must use the same SSID on them all. You have to ensure that the channels don't overlap in any area to avoid interference.

    To avoid channel overlap in the US, set one AP to channel 1, one AP to 6, and the last to channel 11. – gbroiles Aug 1 '10 at 9:40

    I found InSSIDer a valuable to visualize the channel landscape: metageek.net/products/inssider – Jan Aug 2 '10 at 8:21
