I posted about a month ago about a problem with a router and modem,
and now I'm back with the same problem. In my last post I got no
answer to my problem but somehow after playing with the modem and
router, they linked up again.

So here we go again.. out of the blue the internet stopped working on
all networked PCs. I reset the router, the modem, and no luck. I
boot up the modem first, then the router.. nothing. Try router first,
then modem - same. Try both at once - same. Shut both down for 15
min and then try rebooting - same.

When I unplug the cable from the router and plug into the PC, I get a
'Limited or No Connectivity' error. I check the connection settings
and find an 'Automatic Private IP' starting with 169. I then reset
the modem, and it connects to the PC and the internet works. I can
reset the modem over and over while plugged into the router, but it
never works.

I read about the MAC address cloning and used ipconfig /all to get the
physical address of my ethernet port on the PC, and turned cloning on
in the router settings. That still didn't do anything.

Any ideas? I have a Linksys WRT54G router and an Aris Touchstone
Telephony modem (does internet, digital telephone). I remove the
backup battery form the modem when I reset it. My ISP is Comcast.

Thanks,
Doug

It sounds as if your router is/may be failing. Have you had any
peculiarities in your home power? Any electrical storms?

Try asking about possible router failure at one of the forums at

Hi
Internet Not working is the Kitchen sink type of trouble. it does not lead
to a solid answer of ant kind.
You have to find out what exactly is Not working.
1, When this occurs can you log to the Router's menus?
2. If you can look at the Router's WAN menu and see what is the status of
the connection to the Modem.
3. Connect one computer to the Modem (make sure that the computer is
configured to obtain Auto IP).
Switch Off the Computer, switch Off the Modem. Wait 3 min. switch On the
modem and wait to the light to come On indicating that the Modem is
Connected. When the light comes On switch on the computer.
If it is Not working call your ISP.

I went into the router configuration and reset everything to default.
The router seemed to disconnect all computers, then when they linked
up again, everything worked (networking and internet access). No idea
what got messed up in the first place. It just stopped working the
other night.

Thanks for the help,
Doug
