OT:2 cable modems?

by Dave Henri » Thu, 13 Nov 2003 07:36:50

  I have access to two cable modems right now.  Mine, a pretty old 3com
non-Docis modem, and a newer fully Docsis Motorola modem(my son's who moved
to a non-cable area)  I want to move one of my computers across the house,
out of cat5 net cable range from the router and other modem downstairs.  
Can two cable modems co-exist on the same incoming coaxial line?  I would
have to run a splitter to get a 2nd coax line running to the new room, but
both modems would still be on the main line into the house.  Anybody know?  
Startup costs on Wireless are a big roadblock and the distance would
probably be 50 or 60 feet through a floor and several walls...Dunno how
good that would be.

I don't think so. Because the modem ID must be listed at your cable
office. So to run 2 ID's, you'de more than likely have to get a 2nd
account. Feel free to call your cable company and verify this though.

wow,

you must live in a big house ;-).  i though CAT5 could go about 300
feet or so before needing assistance.  How much distance do you have
to go?  And I agree with the previous post.  You cable company maps
your account to the cable modem itself.  I think if you plug the old
one in, nothing is going to happen at all as it will be nonfunctional.
With that said, just plug the thing in and try it.  What have you got
to lose.

good luck,
jeff

  I was always under the impression that 25' from router to NIc was the
norm, with 50' as the max for all the cabling.  I will say that when I use
the longest cable to get to my current upstairs room, my system is much
slower surfing the net than the other three possible system's that are
hooked up in the ba***t.  My son has his 'puter and his friends often
bring a laptop and a desktop system to fill up the ports for my router.  
So when all four are connected..even not actively *** on the net..My
system is noticably slower.  So I figure that stretching the cabling
another 25 or so feet would really be pushing my 100mbs lan.

Yea, they usually charge you $5.00 or so for a second IP though and not
for a full new account.

i've got 100 feet of cat5 that runs to a second router and then another
75 feet off that to one of my computers. works fine.

Well, I ran a 75 footer from my router to my wife's laptop in our bedroom
with no noticable decrease in speed, but I don't think they make cables any
longer than 75 feet.

Oy! dave,

Jeff is correct, cat5 is good for 300ft before needing assistance from
a bridge or switch/router.  In your above description, have your cable
company check your signal strength from the street to the entry point
to your house.  While he's there he should have no problems checking
your sig. strength to your other end points.  You shouldn't have to
pay for this, just call up a tell them your are having intermittent
connectivity issues.  Also, hard code all nics' to 100/full NOT auto
negotiate.  Also, some time ago i used a network tool from netIQ that
monitored point to point transmissions giving stats on latency and
packet loss, may want to check it out by doing a google search.

forgot to mention, try using static IP's for your clients behind the
router.  I had problems few years ago when my sonic wall firewall was
dishing out IP's - browsing was slow going tried everything.  Finally,
set up static IP's and everything was lightning fast.

Anyway, I have a Sun E450 dishing out the goodness from my ba***t
and I have hundred's of feet of cat5 running through the house with no
problems.

good luck....

oh...forgot your other inquiry.  don't waste your time with your 2nd
modem.  it won't work unless the serial (mac) is registered with your
cable company.  even if its registered, you'll need a separate line
running to your house to use it, it will not work 'in - line" with
your other modem.  email me if you want a clarification.

cheers

   Alright, now I remember where I got that 25 + 25 max number...not cat5
specs per se, but before I had a router...before routers became common, I
had a dlink hub.  It was a pile of junk, burnt out 3 times in 2 years, that  
is why I now have a router...but the hub specs specifically limited the
cabling to 50feet max with no one length greater than 25.  So...since I'm a
packrat and still using the original cables, I probably have a very low
quality cable or one that isn't even fully cat5 capable.  
  I've just come back from shopping and picked up some FastCat5e cables.  
I'll see if that makes a difference.  Say goodbye to the old old blue
cable.

   Well that was a failure.  I bought an extra long piece(50ft)
 to test if I could move my box to another room.  An while the ping
reported to the bullrun server is the same, web surfing is dang near at
phone line speeds.-----  blech ------
  With one other machine on the router, much closer and showing normal
cable speeds.

Perhaps adjusting the MTU would help.
