Has anyone gotten an image to tftp to this router over an IP connection (i.e. WITHOUT using a serial console cable)???

 All of the instructions I've found here require the serial cable.

 I'm trying to flash over an ethernet connection - I can ping the router, I'm even sniffing traffic and can see the TFTP read requests coming from the router to my PC, but I can't get the router to download the image from my PC.

 I've tried the command line TFTP in windows:

tftp -i 192.168.1.1 PUT wgr614v8_1_1_11_6_0_36_na.chk

when i do this, i see the tftp write message go to the router in my packet sniffer, but no connection ensues. I'm running the TFTP put just after I see the TFTP read from the router.

 Router's LAN IP is 192.168.1.1

PC's LAN IP is 192.168.1.2

both are plugged into a hub so my windows NIC doesn't go to sleep when I power cycle the router.

I see no reason for this not to work - anyone else see any issues with what I'm doing?

Please help!
