Referring to a good ole post here

Between Level 3 and Level 4 :
Level 3: WR1 - Main Router:
ASUS RT-N16 w/ Tomato USB Router FW 2012 - To be updated - WPA2 - SSID: AS4

Level 4: WR2 - Wireless AP:
TP-Link TL-WR740N (factory fw: 2015) WPA2 - SSID: TP4

WPA2 keys being the same, I am wondering.. if I rename - SSID TP4 to AS4 as well, I would be able to do a WIRELESS HAND OFF between WR1 <> WR2 the way a cellphone hands off between cellphone towers to leverage:
- The better/ stronger Wireless Link
- The Wired (CAT6) Network connected to the relevant Wireless Point

How would this work?

I do not wish to establish a WR1 <> WR2 direct WDS Link as the overlap is small and signals weak in the overlap area. (Near the Staircase)

I'd like for laptops/ phones to be able to seamlessly/ smartly go between WR1 & WR2 while maintaining their Static DHCP IPs (assigned by Tomato USB Router), all the while leveraging the underlying Wired network.

Isn't this this how Wireless works in say a larger building or office / corporate complex when people walk across the building/ levels and their connection to the Fixed Network remains while the connection with Wireless APs changes?
Seamless & Unified for the user

What else do I have to do?

any system of WiFi APs for which the user/client has the SSID/keys will switch among APs. The problem can be that the optimal AP is not selected by the client. And the switch-over time can be seconds which may frustrate the user. Some people elect to give each AP a different SSID, suggestive of it's placement, so the user can override AP selection. Others claim the brand-mix they have of clients and APs or one WiFi router - almost always chooses the optimal AP. Another common problem is clients tend to stick with an AP where due to mobility the client now has a weak signal and there is a closer/better AP.

Hand-off is a misleading term, because in cellular systems, the phone and base station collaborate on optimizing the switch-over - and this is a hand-off. In most consumer WiFi, there is no collaboration (in Enterprise WiFi there can be, with managed APs). Only fairly new and rarely supported (client AND AP) 802.11 standards-options have collaborative handoffs - used mostly fast handoffs in handheld VoIP systems (e.g., Vocera), in professional settings.

The IP addresses and DHCP: Normally, switching APs does not lead to a new DHCP request - switching is a layer 2 activity.
