WAX220 - Configuring guest networks with multiple APs

I think my post makes it pretty clear that I am talking about the guest network settings! The field is simply called "IP address" but, as I say, the manual does not make it clear what IP address should be put in here - the address that the device has, or the address of the network. These are different things so the name of the field should be more explicit. In my view it should either say "Device IP address" or "Network IP address". The former is obviously correct from what you say.

Whatever you say, it is quite likely that in many installations there will be multiple WAX220s installed. Many houses or buildings need more than one access point, and indeed you address this in your other post by saying that multiple WAX220 can be configured into the same network (using WPA2-PSK but not WPA3 which I had already discovered for myself. The manual does not say this!).

As a result I don't see why you are surprised that I am asking questions about how to configure the guest networks in this situation. The manual does not address this at all, but it seems to me that if you set up a guest network with the same SSID on multiple WAX220s there is a probability that a device will roam between them as the user moves around the building so you need to know what to do about that.

In this situation there may presumably be IP address conflicts as two devices may both have valid IP addresses for the network they are on (if the guest network settings are the same on each WAX220) and will not know they need to re-acquire a lease from the AP they have roamed to.

Probably the simplest way of fixing this is may be to give the guest network a different name on each of the WAX220s, but it is rather clumsy as if someone staying in the house wants to connect to the guest network they will have to set up multiple connections for their client device to each of these networks, and it will have to roam between the SSIDs as they move around the building. Not very convenient.

An alternative may be to have the same SSID but set up totally different IP settings for each guest network, and maybe this will prompt the client to acquire a new lease (I don't know whether or not this would happen) but again the manual gives no clue about what to do here.

Furthermore what happens when two WAP220s have overlapping reception areas - will the client device successfully hunt backwards and forwards between them or not?

Possibly the way to do it could be to set each WAX220 with a different IP address, and have different DHCP pools for each one - but that will probably not work because if a client device roams to a different AP they will have a non-conflicting IP address, but be trying to get to the internet through an incorrect gateway IP address, so they will seemingly be connected to the WiFi network but be unable to access the internet. So that probably won't work unless they acquire a new lease, in which case it doesn't matter what you set the pool to anyway.

The manual basically does not address any of these issues with how to configure the guest networks where there are mutiple WAX220s and each approach I have come up with has apparent fundamental issues - that is why I am trying to work out what to do for the best.
