I just bought WHR-G300N and I'm trying to set it up using my MacBook. (If it's relevant, it's a Japanese version.) It is connected to OCN ISP's cable modem, but it should not matter yet. Also, if I plug in my MacBook directly into the modem, the 'Net works.
I tried to set the router up following the instructions enclosed in the box:
a) Connect everything with Ethernet cables, power up everything in order, start AirStation Setup Tool (or whatever it's called in English). I do not see the router listed, no matter how much I Refresh.
b) Disconnect the MacBook, start AOSS Assistant, push the AOSS button, follow instructions. The AOSS is recognised, negotiations begin, and after 10-15 seconds on the second step ("Starting transmission" ) I get an error message "Error has occured (NO_PACKET_INIT)", which is apparently a first even for the mighty Google. :(
I also tried the usual method, supported by the PDF manual I found on your site:
c) Connect everything, point a browser to 192.168.11.1. It's even written on the router body. Nothing there. I also tried .1.1, .2.1 and .10.1. No connection.
The LEDs are:
Power: Green.
Security: Amber (or blinking Amber during and after failing AOSS attempt)
Wireless: Green
Router: Green
Diag: Off
I've run out of things to try. Please help?
