At my wits end here with WRT310N and serial console....any ideas why I cant interrupt the boot? I tried xp, 7 , putty, hyperterminal....nothing working and I read everything I could find on it already (yes I searched)
I have been hitting ctrl+c and/or esc like a maniac when powering on router and neither seem to be working but data is being sent...just not either of those 2 keystrokes
router keeps rebooting in a loop

check your soldering... maybe you have tx on the router connected fine but not rx

[Murrkf]

I have found that it is almost impossible to do this fast enough when working by yourself. Get someone to switch the router on and hit cntl-c like a maniac while it is booting. Make sure caps lock is off.

[barryware]

make sure rx isn't open when testing with an ohm meter (router powered off). Diff router but I fixed one that was missing the smt resister on the rx line.

Also.. it is typically recommended to the connect the adapters tx to it's rx and make sure your key strokes are echo'd in the terminal.

I can also say that if the scroll lock key is on or if flow control is set to anything but off or none, you can not stop the boot.

well after hours of pressing ctrl-c one gets pretty good at pressing those buttons...I think I beat them into the keyboard ...it was the rx connection that was off...a friend had attempted to repair it himself before giving it to me and under the solder for J2 I saw a missing pad...dont ask me but I connected inside the WAN port with a wire and no solder just bent the wire in place and its aliveeeee....thanks for your help guys was at my wits end
