Re: Howto on Cable Modem Connection

A friend of mine has Comcast Internet, and is experiencing numerous
"stalling" occurrences during her Internet sessions. Her XP Pro PC is
hardwired to a Linksys BEFW11S4 router, which also feeds a laptop and
a TiVo wirelessly. Router is connected to a SurfBoard modem.

I tried to trace the route of the incoming cable back to the entrance
point on the house today (having some problems because the entire
basement has a drop ceiling). It appears the incoming cable runs to a
Regal DS4DGH10 splitter. From there, a lead goes to a Regal GRS3DGH
110db EMI Isolator, and the lead to the cable modem takes off from
there.

She called Comcast this week, and the tech who showed up said he
couldn't find anything wrong (he didn't look at anything in the
basement, though). The TiVo, which is using a DLink USB wireless
adapter, was showing Poor (24%) to Marginal (28%) connectivity most of
the time I was there, with an occasional jump to Fair (58%).

I downloaded a firmware upgrade for the Linksys router, and the
download speed started out at 113 kbps, and gradually went up, never
breaking 200 kbps. Applied the upgrade, but no change. Noticed the
Internet light was flashing constantly on the router, which looks odd
to me (my Linksys WRT54G, on a DSL line, has a constant Internet
light).

Any suggestions as to what might be wrong gratefully appreciated.

Access the cable modem statistics page at 192.168.100.1 and check signal to noise ratios and signal levels. The cable modem faq at www.dslreports.com will provide the basis for determining if there are line quality issues from the signal levels.
