Switching routers on Comcast Cable



So I received my new, cheap Linksys WRT54GL router from FON.com. I was finally able to install it.

It came prepacked with FON’s custom firmware. The web interface of FON’s firmware was rather ugly, and the layout they used was buggy; you aren’t able to see some options or fields with Internet Explorer… So I simply reloaded the firmware with the latest from linksys.com.

At first, I wasn’t able to connect to the router. The DHCP server wasn’t handing me a correct IP, but if I set my IP to 192.168.1.100 (gateway 192.168.1.1) for example, it worked. Then I enabled the necessary options in the panel, which enabled the DHCP server, WAP and everything else.

I still wasn’t able to get an IP from comcast. If I plug the cable connection into the old router, it’s able to release and renew its IP, but the new router plugged in isn’t able to get an IP using the same methods. What you have to do is unplug the cable modem for about 1 minute, plug in the new router to the cable modem, then plug in the modem again. This allowed the new router to get a new IP.

I’m not sure why this has to be done, but it’s the only way to make the device with a different MAC address get a new IP. I think Comcast has this to discourage multiple hosts on one connection, but don’t quote me.

    What a timely piece now! Thank you so much for such a fantastic post.
    I saw your books earlier, but this one I believe
    on of the the best, same as this one https://deanrenfrosays.com/learn-algebra/. How can you find so many
    details? I like how you organize everything, since it’s really easy to read.
    In general, I can recommend this guide to everyone who’s interested in that subject.
