For the last couple of weeks I've been having comcast outages
constantly, 5-15 times a day (that I notice). The oddity is that
when the outage occurs, the Toshiba modem lights are all normal
(power/cable/pc solid; data flashing). The outages seldom last longer
than a a couple minutes (long enough to throw me off VPN).
When the outage occurs, I can still talk to other computers on my home
network, leading me to assume, perhaps wrongly, that the linksys
router is OK.
I called comcast to schedule service and got the usual line about how
i would be charged if the problem was in my equipment. How do I tell?
The modem is several years old but its indicators are telling me that
data is being passed. Any thoughts?
Oh, and unplugging the router and waiting and restoring power usually
restores service. This could be incidental since the outages are
short. Thanks

Clarification: I meant: "unplugging the modem and waiting"
I never have to unplug the router.

Have they accessed your modem remotely and tried to diagnose any
problems ?
What model is the modem ?
Does the Toshiba have a status page you can access ? If so, try to
get all the info you can from there and post it when normal and when
failing - esp the Tx/Rx power and SNR. Comcast could be disabling
access to the page if there is one. Try 192.168.100.1 for access
to the page.
If nothing stands out, the obvious next step would be to run without
the router and see if a single computer connected to the modem has
the same issues. If so, you have a modem, cabling or Comcast network
issue and will need to figure out which. If Comcast won't cop to a
network problem, you could save money by taking the modem in for a
swap (I assume they will do that for free if you're renting it or
it's included in fees). You could also try bypassing as much of
your cabling as possible and connect out near the point of ingress
checking your connectors for wear/damage/looseness in the process
and making sure they're all clean and tight. What kind of cable
do you have ? And who did the install ?

It is a Toshiba PCX1100U. It doesn't have a status page you can
access. Comcast remotely cycled the modem today but phone support
couldn't do more than that and that didn't solve problem.
192.168.100.1 doesn't get response. Cursory search indicates that
you can't get to diag on this modem.
I own the modem and installed it myself. It is at least 5 years old
and could very easily be going bad. I was hoping someone might
recognize the oddity of lights on modem indicating normal status while
no data is getting through. I did the cabling and the coax is less
than a year old. Thanks for your response.

What $Bill said: What's the make & model of the modem?
Has an additional signal splitter been installed anywhere on the premises?
Can you go to *EVERY* cable connector and completely unscrew the
connector? Then, re-install and tighten, with a 3/8" open-end wrench,
*slightly* tighter than finger tight.
Pete
