connect airport express to netgear extender ex6100
I'm at my parents' house for the holidays. They have an older imac, but I bought them an airport express so all visitors can connect to the web without wires. Now I need to extend the range of the airport express so I bought the netgear extender.
Can someone tell me how to set up and connect the extender? The netgear instructions are not making sense because the airport doesn't have a WPS button.
Can I use the airport utility? When I open the airport utility, the extender does not show up. The airport shows up, but the extender does not. Can I use manual set up? If so, how?
Thanks!
