I have a workshop in my backyard, about 100ft from the house and purchased a pair of CPE210 extenders to connect the shop to the house wirelessly.

The network consists of the following devices:

Cable Modem --- Archer AXE75 --- CPE210 (AP mode)  ) ) )    ( ( ( CPE210 (Client mode) --- Archer C7

I followed a post here to configure the C7 as an access point, but that caused the gateway to shift to the address of the client CPE or the C7, breaking internet access for any device that picked up the rogue gateway.  TP-Link support suggested I change the C7 to router mode which has resolved the gateway problem but devices I take to the shop now need manual intervention to use the network (I use the same SSID for clients in the house and shop, the CPEs use a different SSID to talk to each other).  Outside the manual connection, the current setup works pretty well, a slower in the shop than I expected but good enough for now.

I am considering purchasing a newer equipment that could be configured as an access point without causing other problems, and boost the WiFi signal on the far side of the house where the CPE210-AP is located.  Would a pair of Deco XE75s configured as access points work in this situation?

Cable Modem --- Archer AXE75 ---  Deco XE75 (AP mode) --- CPE210 (AP mode)  ) ) )    ( ( ( CPE210 (Client mode) --- Deco XE75 (AP mode)

This Deco model matches the main router specs but exceeds the capability of the extended network in the shop due to the limited bandwidth supported by the CPE210... a lower model Deco supporting Ethernet backhaul might work too, like the Deco X10 with minor speed impact at that end of the house.  One strong preference - I would like at least one available Ethernet port on the shop device for a machine there that doesn't work well on wireless, which rules out the more affordable AP only devices.  Other hardware suggestions are welcome too.

Thanks, John
