hi well im here to ask a squirly question ok here goes
i have a home network setup with three comps a netgear GS608 8port gig switch and a huawei mt882 modem router now
comp 1 is about 2ft from the switch so use's a 1.5mtr cat6 cable to marvel yukon 88e8051 pci-e giga nic
comp 2 is on a 5mtr cat5 cable (as its only 10/100) crappy realtec rtl80xx 10/100
comp 3 is on a 10mtr cat6 cable to a dlink DGE500t gig nic or the onboard realtec 10/100

now if i use this exact same setup but instead of the netgear gs608 i use a edimax 10/100 8 port switch we can all connect go back to the netgear and only comp 1 an 2 can connect and comp 3 will not

now its not just this setup i also have a netcom NB5plus4 that does the same thing as with the netgear is there a special cat6 cable that i need to use or is there something else i need to be doing

thanks in advance if you can help

Hi, its a bit hard to read what you are saying, but if I see it right, all computers are ok when you are using the GigE switch, but if instead you just use a 10/100BaseT switch then comp3 wont connect, sounds to me like comp3's NIC has been locked in GigE and wont change down, you may need to lock it down to 10/100.

Hi, as I said, it was a bit hard to read what you stated as the symptoms, rereading what you wrote after your last post, and I think there is still a communication issue, and I am not refering to the ethernet ports.

Anyway, I think you have answered your own question, check your port settings, GigE is well capable of working over either Cat5e or Cat6, and regardless if the ports are set correctly will step back to whatever speed they are happy at, 10BaseT if needed.

The cable lengths you have are so short, there should be no issues with GigE connections, unless they are bacly munted.

yeah thats what i thought too neither the onboard or the dlink dge500t will let it connect to anything but the 10/100 it gets 100mbps connection without a problem it just wont go at all on the gige switch and i've tried forcing the port to 100mbps full and half and 10mbps full or half and nothing nadda not a jot i've sorta worked around the problem by chaining the 10/100 switch to the gige switch and connected to it that way but seems a bit pointless running two switch's for 3 computers. A friends bringing over an STP cat6 cable tommorow to try just incase so we'll see what happens
