How I can stabilize my cisco router performance

Posted on 2010-11-29

I have several home/office computers networked through a cisco router wrt 54G2 V1.  Access to the internet is through a Comcast cable modem.  About once out of every 3 or 4 months, something happens.  Usually it seems that Comcast has gone down - I can still network within the house, but can't reach the internet, even when bypassing the router.  Then, when that issue is finally resolved, it takes DAYS for me to stabilize the router.  First, I need to reboot it about every hour.  All the little Cisco wizards tell me very little, like:  "acquiring network address".  Finally, I get back on, only to have to reboot the entire procedure again, within an hour.  Meanwhile, I can hook a cable directly from the router to my lead computer and I'm on.  However, the other computers still can't access via wireless.  This constant rebooting drives me crazy.  Then finally, after several days, it magically begins to stay connected.  Is there any way I can diagnose what is happening and "force" this router into consistency?  I must warn you, I am not a techie!

have you checked for an updated firmware package on the cisco site?

log into the router and the firmware version should be listed there.  then go to the cisco site and see the latest firmware for that model and version is different than the version on the router.

if it is then download the latest firmware package and under the adminitration tab in the router interface select firmware upgrade, then browse to the location of the file... click the upload button and DON'T TURN IT OFF until the upgrade is complete.

good times!

I'm sorry, I forgot to mention (especially because I knew it would be one of the first things to check) that I have, and continue to have, the current updated firmware

you may simply have a bad router.. it  does happen.  If you have the most updated firmware and the problem persists there is not much you can do.  the last thing I would try is to back up your configuration settings and reset the router.  Re-enter your settings manually don't use the backup config file.  

If that doesn't work it is new router city in my book.

True to form, after a few days of re-booting the router several times during each day, things finally stabilized.  Everything has been running fine for the past week.  And, I'm sure it will stay that way for quite a while now.  It's just very confusing when everything goes down.  It generally starts with a hiccup from the provider (in this case Comcast).  I assume it's on their end, because I strip everything away and connect one computer directly to the Comcast modem with a cat 5 cable, and get no connection to the internet.  Then, when service is finally restored, that's when it takes several days for the router to stabilize.  I just thought there was a way to manually force my router to "shake hands" with the modem and internet provider - to refresh or re-register its address, or whatever.  It all still remains a mystery to me.  Crossing my fingers still seems to be my most important technical activity.
