Router Issues

Hiya all..

I am having an issue with my router renewing the IP...Usually everynight, sometimes every other night Comcast sends out new IP's or atleast that is what I am assuming..
So I lose my connection every time this happens and need to unplug and reboot the modem, then recycle the router and reboot my computer. I dont know very much about this sort of stuff...but is there a setting or something that could be causing the
router not to renew the ip? It is a older router, have had it for a few years now.
I have the latest firmware I can get for it ect..Linksys BEFW11S4 Wireless Router.

Does it happen if you take the router out of the picture? i.e. Connect directly to the modem.

It could be a problem with your modem, have you called your ISP?

what brand of router ?
i found mine would over heat like a dummy . i used it as a letter holder on my desk . and that would cut off the air flow between it and the wall . remove anything blocking the air holes around the unit and see if that works !

Read further down in his original post... HAHAHAHA! Grin

(yes, yes I'm an a$$)

But Ren does have a point, it's worth a shot. Also I would recommend trying a few things such as doing a factory reset (remember to write down all your info first):

Clone the MAC, and be sure the router and computers are set for DHCP.
while Comcast gives short IP leases (2-24 hours) while doing local maintainace and upgrade work, (which they are doing alot of right now) their normal lease is 1 week.
and they usually assign your IP by the MAC "learned"address (from your routers MAC, cloned or not). If I clone a different MAC to the computer I get a new IP, but when I reclone my main MAC (within the lease time window) my old IP that I've had for 6 months returns.
You must SAVE and powercycle the modem/router and computers after cloning for it to save that info, if it continues have ComCast manually reregister the the routers MAC. Keep calling until you get a tech with this skill/ability (many only answer the phone and read from the menu, thinking is not in their skillset Rolling Eyes

) or get bumped up to 2.5 tier support. (<<<more experienced, still not brain surgeons)

Could simply be time for a new router. My Linksys BEFSR41 just stopped holding onto IP addresses not to long ago. I had to reset it all of the time just to get onto the internet. Finally, it failed all-together.

I've replaced it with a Netgear unit and the internet has been flawless ever since.

I have a linksys and it started acting up. I still havent figured it out which was the problem but I reset it to factory default, but before you do that go make sure the Keep Alive:Redial Period is set to 20 seconds, I found a sprint white paper that suggested that.
