Same SSID on WEB600Q

Installed Gigabit plan on Tuesday. Tech put in a T3200M & a Web600Q upstairs in the master hardwired in. 

Only thing is now I have 4 different SSID's, two for each 2.4ghz & 5ghz. I'd prefer to have just 2 one for each speed and have the extender just extend the same SSID.

Any way of making this work?
