packet loss in the network

By quayoom ·
When I ping the default gateway and the novell servers on the network, Often it is experienced a packet loss of 25% somethimes 50%. Previously the node was on a shared hub, now I connected it on a dedicated 10 base t port on catalyst 5500 switch, still its experiencing the packet loss, NIc is 3Com 10/100 Ethernet, the settings for the NIC card is set to 10 Mbps, Duplex Auto
No other host on this segment is having such problem. What might be the problem? Any solutions higly appreciated

To add a separate hub you had to add wiring/cables. Since you added the hub check all new connections, and replace the "NEW" cable with a known good one. Try different ports on the hub.

Good Luck!

I would check to see if you can get the problem to move. Is this the only machine of this kind on that segment. I have seen NIC cards cause "STORMS" which would make it look like a packet loss. Try this NIC in a different machine and see if the problem moves to that machine. If not you could try to move a machine to that location to check the current wiring. It may be an environmental problem. I would check the nic first

Take a quick look at your hubs/switches/etc. and try to see if there is an excessive amount of traffic over your network. If the network gets too flooded with traffic, your going to get collisions regularly, which can easily lead to bad packet loss.Also, when network cards go bad, they do cause "storms" of packets being sent, faulty NIC's can sometimes bring a fast network to a halt. Also check your cabling too, bad connections are well, bad connections.

Thaanks, there was no excessive traffic on the network as the switch load is barely 5-10%. The problem was with the NIC after replacing it working fine.

On our network, we've seen a fair number of problems related to 3Com NIC cards failing to auto-negotiate properly when spanning tree protocol is configured on our Catalyst switchs. Our solution has been to disable Spanning Tree Protocol on those ports.

Alternately, the problem sometimes goes away if you explictly set the NIC for the right settings (e.g. 10Meg Full Duplex) rather than letting it auto-negotiate.

Thanks very much for all those who answered my question. The problem was solved by replacing the NIC Card.
