Hi experts,

I would like to setup a wireless network that consist of multiple wifi routers/APs with only one ssid such that users can automatically connect to the other wifi hot spot when the one he is currently connected with either at low signal or out of range.

is this possible? please suggest some solution and choice of wifi router

thanks!

Yes, that's how roaming works.  Any wireless routers or access points should work fine like that. I suggest making sure they support WPA2 encryption.

Some client operating systems and/or connection managers will switch faster than others when roaming. i.e. some clients may have a 15 to 30 second interruption in connectivity when switching between stations if they don't support Fast Reconnect (that makes the client pre-authenticate with the approaching station before disconnecting from the weakening station).

so is that all the wireless routers need to be of the same model and brand?

what i am thinking is using 4-5 wireless routers, one of them act as the primary that internet line will connected to and also responsible for DHCP, the other will simply connected to the primary one and only use the wireless function. All routers will have a static IP address. The Wireless SSID, encryption and password are all the same in all wireless router.

router1: primary, uplink connected to internet, other ports connected to other routers, DHCP, wifi enabled
router2-4: enable wifi, connect non uplink port to one of the non uplink ports of router1.

am i correct?

b.t.w, from what you explain in last post, it seems to me the roaming is done by client but not the wireless router?

many thanks

No, but being all the same doesn't hurt anything, either.


> router1: primary, uplink connected to internet, other ports connected to other routers, DHCP, wifi enabled

All that sounds correct. Don't forget to disable the DHCP server on router2-4.

If using 802.1x authentication (aka enterprise/RADIUS), there is a setting in windows server that needs to be enabled, but otherwise it's mostly up to the client.  Some rely on their connection manager, while others have adjustments for it at the driver level. See attached for examples of both. Without those settings, the adapter typically attempts to maintain the current connection as long as possible, then when it finally drops the connection it will (re)attach to the strongest signal.
