For my guest network at my facility, I've got a TP-Link Archer A7 AC1750 router dedicated solely to my that network (I've turned off the guest network within that router since the entire router is decidated to the guest network and that would be somewhat redundant and unnecessary). That router sits in one corner of the facility and puts out the WiFi SSIDs "XYZ Guest 2.4G" and 5G. 

To provide additional coverage through the facility, I've got an EAP225 unit connected to that router, which sits in the opposite corner of the building. That AP puts out the WiFi SSIDs "XYZ GuestB 2.4G" and 5G. I'd like guests to be able to connect once to a WiFi in either end of the building and have it automatically keep them connected even if they move to the stronger signal at the other side of the building. 

Problem is, now I've got 2 devices (1 router + 1 access point), each with their own pair of WiFi SSIDs (one for 2.4G and one for 5G) which makes things somewhat cumbersome because when someone wants to get on the guest network they see 4 choices:

XYZ Guest 2.4G

XYZ Guest 5G

XYZ GuestB 2.4G

XYZ GuestB 5G

I'd rather just give them 2 choices, at most (2.4G and 5G), but I'm not sure if I'm creating some sort of conflict if I name the SSIDs the same name. Is there a way to combine all of these into 1 or at most, 2 SSIDs? 

Thanks in advance!
