Workgroup has slow internet access

  1. Hello all,

    I have a small work group of about 8 computers, some on Ethernet and some wireless. The DSL modem goes into a lynksys wireless g 4 port router (which has wireless turned off). The router does into a 15 port switch, which all the computers are connected to along with a wireless access point another 4 port switch and a printer.

    Our Internet connection speeds are very slow on all the computers, but file transfers across the work group are fine.

    I have tested the Internet connection speed at the modem with a laptop and get 4Mbps after the router speeds are 2.5Mbps and after the switch it is 0.3Mbps! I have checked the cabling and run virus scans but so far can't find the cause of the slowdown.

    Any ideas what else I could try?

    It could be the switch, itself. Have you tried swapping it with another one?

    First, using a switch for all systems should be a great thing to do as it will reduce
    junk IP traffic seen be all systems.

    I would verify the settings for all wired systems being 10/100 and NOT use the gigabit
    rate if the card supports it -- it would just swamp the switch and or router.

    solved

    Hello and thanks for the replys. It turns out that the problem was a dying router, a dying modem, and line noise in the building telephone switching room because our DSL line was running too close to too many T1's. We went from 129kbps to 1200kbps with replace ment of the router, up to 2500kbps with replacement of the modem and now 4000kpbs with correcting of DSL wiring problems. The tech for Qwest was extremely helpful in tracing down all the diffrent errors that were occuring.
