Thread: slow network with INTEL DP55WB PCI-E/PCI

-

recently replaced old redhat server new machine installed latest ubuntu server version. samba share made on new server. transfer of files client pc's server 20 times slower before. when transfer files between 2 client pc's in same network goes fast.

i'm not ubuntu expert, did other installations , never had problems network or network cards. works automatically.

configuration of machine is:
motherboard: intel dp55wb pci-e/pci onboard network 1gb
processor: intel i7-870 2930 mhz

tried things within ubuntu, didn't help. so, thought, leave it, disable onboard network card in de bios , put network card in machine. tried 2 basic network cards (realtek). put them in pci-slot in machine , can see in bios machine noticed there new hardware in machine. in ubuntu network cards not found. there no eth0 when ifconfig. think strange because cards automatically visible in ubuntu.

ideas or suggestions. hardware problem, corrupt motherboard or bios setting. read somewhere dp55wb unreliable motherboard.

did check if onboard intel nic running in 10 mbit/s mode?
every new card add create new node, eth1, eth2, etc.
unless edit /etc/udev/rules.d/70-persistent-net.rules , remove references old cards.
hardware choice reminds me desktop, not server. server should have sufficient cpu - i7 terrible overkill unless run lots of virtual machines , quality motherboard dp55wb not.
of time people replacing aging servers better off used blade ebay.
