Topic: nic gig running at 100

[muzzy]

Hi

was wondering if anyone can shed some light i have sme 7.5.1 and its running just great. my only snag i my internal lan card which is from the motherboard and is stated to be a gig card is only running at 100mbs my second card is running fine at 100mb which is the best it can do. i searched google and found ethtools to force it to a gig but all this did was shut it down. has anyone had this problem before and know how to sort it or is it more that i have it messed up somewhere?

thank you in advance

Are you sure the other site of the connection also support Gb speeds?

Following on from cactus' comment, Does your network switch or hub support 1Gb & are the ports actually running at that speed, does the cabling support 1G & is it wired (pinout wise ie 4 pair vs 2 pair) to support the faster speed ?

[muzzy]

yes the other end and cable all support gig speeds and they have all been test with a gig windows laptops as well they were all tested when it was all installed the other side is a gig switch which is brand new. i tried forcing the change of speed but when i restarted the file was recreated and all changes where removed. so any insite will be great i am going to have another look around see if i can find anything on the redhat sites or fedora site i looked at the centos but the version 4 forums were not there.

anyway

cheers

my guess is a hardware failure: onboard NIC.
You could try to use another OFFBOARD NIC , a Intel is better, to test anything else and locate the problem.

It may be the NIC himself or  SME/RHEL4 drivers to him.

But do not force Gig speed by hand... if NICs could not garantee the speed they do not use it.

Good luck.

the speed of the network card is advertised as being a gig. but i have been testing more cables and a cross over seems that the cross over does give a gig speed so there must be a fault in the cable somewhere i will have to go narrow it down. thanks for all your input
