How can I improve the strength of a long-distance wired LAN connection?

Dharmendra March 23, 2012

My network has connected one system via 86 meters of LAN wire. However, the strength of the signal is weak. As a result the system has a lot of issues like mail attachments not going through and some sites not opening. How can I improve the strength of the connection? I am using Cat6 LAN cables.

    The following recommendation can be used to increase network performance:

    1.Add additional network cards to computers in the BizTalk Server environment2.Implement network segmentation3.Where possible, replace hubs with switches4.Remove unnecessary network protocols5.Scalable Network Pack(try disabling it)6Network adapter drivers on all computers in the BizTalk Server environment should be tuned for performance

      Who said anything about Biztalk servers? Please dont copy paste content, it gets us DMCA notices.

    turn off everything (server, hub, cable modem), take their power off and connect all over againLAN vs WAN
    LANs have a high data transfer rate
    high speed(1000mbps)

    Signal loss is referred to as Attenuation.
    CAT-5 is rated to 100M
    CAT-5e is rated to 350M
    CAT-6 and CAT6e is rated to 550M or 1000M depending on your source
    CAT-7 is supposedly rated to 700M or presumably 1000M

    Comparison between CAT5, CAT5e, CAT6, CAT7 Cables

     factors to consider are:
    * The quality, length and copper composition of the cable
    * Electromagnetic interference

    First, are you sure that there is nothing along the run that is introducing noise into the line since you are under the standard 100m length limit?  I have run lines longer than 100m without problems, which is why I am asking.  If you have a Fluke meter to check signal levels, you may also want to take a closer look at your signal-to-noise ratio as well to determine if anything else would help.

    If you are not over the noise cap, you can use an Ethernet repeater to boost your signal strength.  You can also use a switch or hub to get the same effect.  In any case, if noise is the issue, boosting the signal strength with a repeater, hub or switch will not help the situation.  Instead, you need to isolate the source of the noise on the line and deal with that.
