Hi, After reading couple of previous posts, I have not seen the answer to my question below. I have a WRT54GS (2.07.1 firmware before, upgraded today to 3.37.2). I exchanged the expander one time. In spite of multiple attempts (Auto config, CD set up, reset of expander), the WRE54G cannot connect to my router and still show the Red link. Any idea on how to make it work ? Thanks in advance.
