WRT54G Linksys router drops internet, with Cable (blue ridge communications)

Hi, I setup a WRT54G wireless router for a client, and it worked fine for 3 weeks, until yesterday.  It would drop the internet connection about every 8 hours.  I replaced the router, assuming that was what the problem was with.  This did not helpl at all.  It still does the same thing.  If you plug the computer directly into the cable modem it still works there, so it seems like the cable modem is the problem.  A restart of the router cause it to come back again, but nobody wants to restart their router twice a day!
   Thanks in advance!

Current comment from venom96737: Sounds like you need the winsocks fix found here http://www.snapfiles.com/get/winsockxpfix.html download run and reboot should be good to go.

First thing is to verify what is dropping.  Have you looked at the log of the cable modem?  Does it show anything dropping?

The next time is stops, go into the Web Managment pages of the WRT54G, select the Admin tab and the diagnostics.  Now ping your modem.  If that works, then the connection between your WRT54G and modem is fine.  Now ping something on the Internet, www.apple.com normally works, but you can try any host that you KNOW will respond to pings.

Oh, while you are in the Web Management interface click on the status tab and see what it is.  Also make sure you have the latest firmware on the WRT54G.

Called the cable company, the modem is not dropping the internet.  I suspect is may be a problem with the computer connected to it, like callrs suggested.

Umm, what?

---> If you plug the computer directly into the cable modem it still works there, so it seems like the cable modem is the problem.

If there is no problem when the computer is directly connected to the cable modem, then you are correct in your assumption, the problem may be with the WRT54G. Based on what you are saying, when you have:

  COMPUTER <---> WRT54G <----> Modem <----> Internet

randmomly the Intenet drops out.  However if you have:

  COMPUTER <---> Modem <----> Internet

Everything works fine, then it does indicate an issue with the WRT54G.  If you had problems with both situations, then it would indicate a problem with the computer.

When the Internet drops, can you get the the WRT54G Web managment interface?  Can you ping the WRT54G?  If both answers are yes, then the problem is NOT with the computer.  If the answer is yes to both, then the problem could be with the computer or the WRT54G.   However as you say when you remove the WRT56G from the picture, everything is fine, it does indicate the problem may be with the WRT54G or one of the cables.  Try connecting the computer to the modem again, but this time use the other cable.


If you can get to the WRT54G Web mananamgent interface and you can ping the WRT54G, then trying pinging the mode and try getting to its managment interface.  If you can get there, then the problem is on "the otherside" of the modem.

does your isp require the mac addr of the modem only or both it an either a nic's or router's mac addr?  if the latter then make sure they have the mac of the router to, or it the acct was set up with the nic, set your router to clone the mac addr from the nic.
