can two wifi extenders provide service to one LAN?

extender A talks to wireless network A whose SSID is 'wireless A'. Extender A provides a boosted wireless signal locally. The local network it provides is named 'extended wireless A'. Extender A also has gigabit ethernet ports. Extender A does not do any natting and simply provides IP addresses as they are doled out by the router servicing hotspot A.

extender B talks to wireless network B and also provides a boosted wireless signal locally. Extender B also has gigabit ethernet ports. Again extender B simply passes on the IP addresses doled out by the router of wireless network B.

Since the local wireless networks these extenders provide are different, there is no conflict. My computer can join either wireless network with out a problem. However, can I connect
these two extenders to coexist on the same wired LAN? Will my bandwidth be the sum of the bandwidths of the two wireless networks?

Yes, provided they don't interfere with each other in the wireless , ie set them to different channels or bands.
No. They don't add, they can only interfere and subtract.

You get higher total bandwidth only if the networks are not sharing channels. Best case would be to have one on 2.4 GHz and the other on 5 GHz.

Ok. But suppose one wireless network is in the 192.168.1.x space , the extender is going to provide access to that ip range ( from the router to which it is connected). And the other network is on the 10.1.10.x so the other extender is going to provide those addresses ( doled out by the router it is extending) . Since both extenders have Ethernet ports , I could plug them into the same wired network.

Now if a pc is connected by Ethernet cable to this LAN, and its network settings are set to DHCP, which network will it join? Is that a random event as to which upstream router it sees first? Is there a way to 'aggregate' these two networks into a single new address space that has bandwidth equal to their sum?

Everything needs to be on the same subnet unless you have a router capable of supporting and routing between subnets.
