Wifi issue - two access points.

Before I start, I appreciate this is a first world problem of the highest order, but this is probably a good place to ask...

At Scruff towers I have built a garden office for wfh. This has a wifi access router, linked by cat5 cable to the main house.

Both the house and office are broadcasting "scruff wifi" with the same password. Turning on wifi connects to the stronger access point wherever the device is. So far so good.

However when I go the office in the morning, my phone(android fwiw) sticks to the home wifi with 1 bar of reception at the end of the garden and slow speeds and doesn't jump to the other router with full reception and fast speeds.

Is there a setting to enable/force the device to use whichever access point has the strongest reception?

Thanks
