New Home Network Starting Up Trouble

    I have got my house rewired for a home network.

    The equipment is as listed below:
    1) WAG54Gv2
    2) SD-208 - Linksys 8 port switch
    3) D-Lnk Cat 6 cabling with Krone Terminators/Jacks
    4) 1 Desktop, 2 Laptops, 1 Rio Receiver, 1 HP Media Player, 1 D-Link Media Player

    I have the WAG54G set up in a central place in the house to enable good wireless signal availability throughout the house. I have the output from the WAG54G being given to two network cables, through patch cords.

    The output of these network cables are in another room, and are given as inputs to the SD-208 switches, once again using patch cables. From the same board I have cables running to different rooms in the house. Each of the starting points is connected to the switch with a patch cord. And in the respective rooms I am finally connecting the device to the network with a patch cord.

    Once I wire all the components in I am not able to get the wired netwrok to work, my desktop pc even fails to get an IP address on the network, says limited or no connectivity.

    If i connect all things directly they work flawlessly. Even the media players to their server software on the desktop.

    Needless to say wireless is always working flawlessly.

    Did I go wrong in my set up? Or could it just be a bad crimping job? Or is the wire bad? I have a network cabel tester, the one that does the 8 light dance, do I need to do any moe tests?

    Appreaciate all the help and advice i can get, it has been three weeks since I have been breaking my head over this.

    If I read your story right, it sounds like you have two ethernet cables going from the WAG54G router to the SD208 switch.... If this is the case, thats likely your problem. You can only have one cable connecting the two devices as neither of them support what is called 'trunking.' I'm guessing you wanted to get as much bandwidth as possible and had two ports left over on the switch. Not a big problem, but it won't work ;-)

    The ports on both are Auto detect, so no need to use a special crossover cable to anythign, just pull one out and you should be good to go!

    Let us know how things go!

    I have 2 SD-208's so I have one ethernet cable each going from one output each on the WAG54G to the switches serving as their input. Good point you brought up, I am currently using all straight-through cables.

    Let me see if I can get a couple of photographs posted shortly, that will give you a better idea.

    Home Network 001 - This is where I am hooking up the WAG54G on the SM-01. I take any two out puts from the 4 port switch on the WAG54G and plug them into the network ports above.

    Home Network 002 - The end of the two ports that I uploaded the WAG54G output to are available here. I connect each switch (I have 2 SD-208's as i mentioned) to each of the ports.

    Then I connect the switch output to the other port/s that feeds the other room/s.

    Home Network 003 - This is one of the rooms where I intend to connect a PC/ Media Player device.

    All interconnects are also done using straight through cables. The maximum length from the WAG54G to the farthest network point in the house would not exceed 100 feet.

    Looking forward to some indication of how I can resolve the problem.

    First off, very neat installation. I especially like the setup you have for the WAG installation.

    I'm a little stumped...is there a possibility that in wiring up the jacks, the were keyed wrong or backwards?

    You said that everything works if you bypass the switches. Is this the case when only using one or both? can you plug the switch in physically next to the WAG to avoid as much in wall cabling and see if devices plugged into the large jack outlet will pass through to the switch?

    Are you getting link lights on the WAG at all when you plug in the switches? How about link lights on the switches when devices are plugged in?

    This is an interesting problem and will probably require changing just one variable at a time to see what the problem is. I'll keep thinking on it too.

    Two scenarios

    Let me bypass the in wall cabling and do the following and get back to you with the results:

    1) a) Connect the 2 switches directly to the WAG54G.
    b) Connect all devices on various ports of the switches and see how they talk to each other, especially the media players to their server softwares on the desktop.

    I think I have already tried this and verified eveything as working fine, but will try once more anyhow and revert.

    2) a) Connect the WAG54G switch outputs to the jacks above them and connect two devices: one desktop and one media player to the corresponding outputs on the large jack panel and see if it works.

    What are the chances of line losses on Cat 6 given the multiple interconnects using patch cables and is there a way to test this?

    Replies to your questions

    Are you getting link lights on the WAG at all when you plug in the switches?

    Yes I do get link lights.

    How about link lights on the switches when devices are plugged in?

    Yes again.

    Results of Testing for Jdepew

    Scenario 1:
    Equipment: 1 Laptop
    1 Desktop
    1 WAG54G
    1 Rio Receiver
    1 D-Link DSM-320RD

    Wireless turned off. All devices connected directly to the switch on the WAG54G using straight through cables. Everything works fine. Kept moving devices between ports and they still work fine.

    Scenario 2:
    Equipment: 1 Laptop
    1 Desktop
    1 WAG54G
    1 Rio Receiver
    1 D-Link DSM-320RD
    1 SD-208 switch

    Wireless turned off again. Switch connected to WAG54G and various devices connected through either the switch or the WAG54G in various arbitrary connnections (kept moving things around). All straight through cables used. Everything works fine.

    Scenario 3:
    Equipment: 1 Laptop
    1 Desktop
    1 WAG54G
    1 Rio Receiver
    1 D-Link DSM-320RD
    1 + 1 SD-208 switch

    Wireless turned off. Switches connected individually to WAG54G independently using straight cables as well as one switch connected to WAG54G through straight cable and the other switch connected to the first switch through a cross over cable.

    Everything works like a knife through butter, hot knife I mean.

    Scenario 4:
    Equipment: 1 Laptop
    1 Desktop
    1 WAG54G

    I now connected the WAG54G ports to the inputs above them and ran a wire from their termination on the large jack panel to the desktop. Pinging still happening but % loss increasing.

    Scenario 5:
    Equipment: 1 Laptop
    1 Desktop
    1 WAG54G
    1 SD-208

    I now connected a switch to the termination on the large jack panel and ran a cable from the switch to the desktop. Still works but performance dropping and % loss in pinging increases further.

    All this while my network card is set to Auto and is connecting without issues at 100 mbps.

    Scenario 6:
    Equipment: 1 Laptop
    1 Desktop
    1 WAG54G
    1 SD-208

    Same as above. But now i am connecting the switch's output to be able to get an output on the jack next to the desktop in the other room on large jack panel. I then connect the computer wtih a patch panel.

    Three behavious noticed.

    a) Unable to get IP allocated, ends up with "Limited or No Connectivity" message.
    b) Dropping to half duplex seems to help sometimes but not often.
    c) Static IP assignment to the desktop leads to a "no problems" connection bu that connection actually is only one way.

    Pinging the same sites as above under this set up leads either timesouts or host could not be reached errors.

    That's it from me. Is it the wiring or rather crimping?

    Looking forward to hearing from you soon.
