Very easy to do the same setting without going through the WPS button.
If you can connect a computer or a smartphone or tablet or other wifi connection, you'll make the adjustment. Thereafter, it is advisable to save the setting (handy for those two sources wifi and therefore able to choose one or the other restaurant in the desired backup).
For those interested, you can connect a router to the Ethernet port. I just did the test at the moment with an old Netgear router RP614V3. Less than 5 minutes to make it work. Of course, then some switches can be connected to the router in addition to that incorporated in the latter. I guess a wifi router could be connected to further extend over the spread of wifi further than the repeater!
