Well, the summary pretty much says it all.
I wanted to install TomatoUSB over current Cisco firmware on my new Linksys by Cisco E3000 router, to be able to use it as a printer server as well (why on earth Cisco hasn't provided that feature I'll never know, thankfully there are people like you who make 3rd party firmware). Before upgrading firmware, I didn't have any connection issues, but after installning TomatoUSB (E3000 Ext firmware), I couldn't get my router to recieve an IP address from my ISP. I talked to the ISP, and they told me that perhaps it could be some WAN setting (like not having the option of choosing dynamic DHCP instead of just DHCP), claiming that there oughn't be any problems. I doubt this explanation somewhat, but I'm at a loss figuring out what to do. As it is right now I went back to Cisco firmware to get a stable connection (which I did), but this is of course a sub-optimal solution. Does anyone have any idea what I should do, or is TomatoUSB and my ISP just never going to get along?
Thankful for any help at all.
