This is odd, no matter what I try, I can't get a IP from Charter from the cable modem. Using tomato shibby 1.28 on a Asus n66u. What happens is, it first pulls down a 192.168.100 IP from cable modem (which is correct), then it goes to 0.0.0.0, and hitting 'renew' won't bring up anything. Logs don't show anything of value. I even waited for over 10 mins... nadda. The only way I can get it to work is, hook up my old router up (DD-wrt), it pulls down 192.168.1.100 like before, then after about 20 secs after it is 0.0.0.0, it gets the real IP. I then disconnect the old router, and plug in the new router, and work that way. (I already cloned the MAC of the 1st router, and NO, I am not required to use a certain MAC). After some reading around, I noticed on openwrt page, it says: I do have a DOCSIS 3 modem from Charter, but I am unsure where to enable that flag on tomato ? Any pointers on how to enable the above flag, or trouble shoot DHCP ?
