cable modem crawling

A little help here, 99% of the time while using my cable modem everything is great, then, for whatever reason everything just slows to a crawl. Web pages seem to load at the speed of a 2400 bps (slow for those who missed out on those). It doesn't matter what page im loading. I shut down the browser but that doesn't help. MS Outlook also slows to a crawl. When I reboot my computer....BAM!!! blazing speed again....but it could crawl at any time :(
Generally(but not exclusively) i see it most often when im really pushing it. ie: video downloads, MP3 downloads(5 at a time) etc.
Has anyone experienced this?

My ISP is no help, there reply... "well sir, there are times when you will experience reduced x-fer rates, for example, when a large volume of users are logged on"

This guy was a big help, there is a difference btwn reduced x-fer rates and litteraly crawling.

I am starting to think this may be an issue with my nic. (D-link)

system spec's
IE 5.0
Outlook 2000
Motorola modem

  1. Tell a little more like cpu speed, how much ram, mother board, video card, ect... stuff like that.

  2. Thanks for the reply

    I could of given that info initially but im not really sure much of that has anything to do with my problem, remember i said i normally experience great download speed, its just the occasional hault i get.

    CPU K6-2 450 BCM board with ALI chipset
    64mg, AGP ATI expert 98 16mg
    D-Link NIC
    Motorola modem
  3. I don't think that hardware has anything to do with your problem (excpet maybe the network card). I have a Pentium 60 on my shared cable connection, and it can download at 650KB/s just like the rest of my computers.

    Have you checked to make sure your using the latest NIC and motherboard drivers? I have three D-link cards and have never had a problem like that, but I am probably just lucky because the other D-link products I've had were crap. Network cards are inexpensive, so you may want to just go buy a new NIC just to be sure.
  4. I have the same problem except I am using a 56k modem and Windows 95. Things seems to just slow down the they stop. The only thing that I can figure out with mine is shut the computer completely off and turn it back on again. I am guessing that my memory or cache is starting to so its age. It can also be a memory leak.

    AMD K6-3 400mhz
    GA5-AX ver 4.1
    USR 56k ISA modem (gotta love these old hardware modems):)
    64 meg
    Maxtor 4gig udma33 and 2 gig DMA hardrives
    Samsung 32x cdrom
    HP 8250i CDRW(it is really a 8290, in other words I think it is the Phillips ver)
    Voodoo 3 2k pci(so sue me it was cheap)
    Linksys fast ethernet card 10/100 hooked up to my Linksys Hub which is hooked up to my wife's computer.
  5. Yoda, i was thinking of dropping a new NIC in, i guess it cant hurt and your right they are cheap. As far as drivers go i haven't updated the NIC or Mbo. I guess what really kills me is that this is the configuration (NIC, Drivers etc) my ISP installed. I shouldn't have to troubleshoot this dam thing at $40 per month. There latest reply to me was to disable the proxy settings or detection or whatever its called, i did this and used the net for about 90 minutes at blazinging speed but just when i thought i was out of the woods......bam!!! c r a w l i n g again.

    lostinms mentioned a memory or cache problem, wouldn't either of these show up in other software applications?? when my browser slows and i close it everything else on the computer seems to run fine, once i reboot the browser is fine again too.

    Thanks for the input, as soon as i get this resolved i will post the cause.

    If anyone else cares to share thier input it would be greatly appreciated. I cant belive i am the only human experiencing this with with a cable modem.

    thanks again yoad and lostinms.....
  6. Ok, i dropped in a Lynksys 10/100 and havent had a problem for the last 5 days. Hope this helps someone else.
  7. I have Linksys, NetGear, and D-Link network cards.
    My personal preference is for the Linksys cards.
    They just seem to work better. I think they are faster.
  8. D-link was my first experience(isp installed) but i will stick with Linksys from now on.
  9. Try a 3Com NIC. You can not go wrong with 3Com. I use a 3CR990 NIC with an on board processor. This card smoothed out my cable modem connection. Also go to, this is a sight to tweak out your cable modem....
  10. i am a network admin and i would recomend cable....
    anywho, where are you locate? if people in your neighborehood are using the cable connection at the same time, naturally your connection speed will decrease. cable is a bridged/shared broadband. i'll bet your connection is fine during late night and early mornings. try uncapping your cable modem. that might help upstream.

    If you can't beat 'em kill 'em
