I tried to add this AirStation to my network as an access point. So I opened the User guide. In the page 23, under title 'Connecting to a Preexisting Network', step one tells me to move the switch in the bottom to position AP. In my WHR there's no such a position, only AUTO-OFF-ON. Which one of those three is the 'AP' position?
I tried all of those but didn't manage to catch the device from the suggested IP (192.168.11.137) mentioned in step three. It was every time in either 192.168.11.1. or 192.168.11.100.
Thanks for the answer, I'll try your suggestion tonight. Maybe indeed also the pc's ip should be static, since the box isn't in the router mode. Although I did reach the box from both ips.
By the way, there's the same page 'Connecting to a Preexisting Network' also in WHR-G125's manual (p.22). Precisely the same text. Maybe this mysterious ip 192.168.11.137 applies to that device..? I wonder if the page has been left intentionally in both manuals.
