10/100 ethernet network speed question.
Posted on 2010-09-16
I am sure this is a rather easy question for some of you Cisco guys/ gals, but I have tried troubleshooting a speed issue within my small office.
Basically, I have a comcast business class router that is connected to a netgear 10/100 24 port unmanaged switch (unmanaged - I can't make any changes, VLANs, etc) that then has only 8 ports being utilized by ethernet CAT 6. There are five systems that are connected all the time and each has a 10/100 or GB NIC. I set the NICs to full duplex 100.
With that being configured the way it is you would assume that file transfer rates between computers would be above the 10 MB and less than 100 MB rate. However, whenever I start transfering large files < 1GB, I will consistantly get connection speeds in the 1 - 3 MB range. I have sniffed the network and really don't see much traffic that would slow down the connection.
I was guessing that it was the router that was the cause behind this since it controls the DHCP, etc. Is that correct? Should I put another router behind the modem/ comcast router that can switch at the 10/100 MB level for internal files?
Your expertise is much appreciated.
