 "devices right next to the router" could be part of the problem. The
received RF power levels could be causing front-end overload and
distortion.

 I'd presume the two (or more) are using different WiFi channels (there
are only about 3 channels in the 2.4GHz WiFi band that can be used without
overlapping bandwidth). That presumes your "extender" is hard-wired, and
not a WiFi repeater.

 Same channel probably expects clients to communicate with which ever
node is the strongest -- without having to change channels. Note that using
different SSID does mean the client has to disconnect from one SSID and
negotiate a connection with the other (and if you are somewhere equidistant
from both, might run the risk of sporadic signal loss/connect cycles).
