I have an issue that I've not been able to figure out.
Our network in a nutshell, ISP line is Fiber Optics, coming in to location. ISP fiber box has a 3' Cat5e cable connected to the main router. Main router has about a 55' Cat5e cable running to our (Net-gear =48 port 10/100/1000=1GB switch). From this switch we are running to our server that is acting as the DHCP, & DC. We have about 10 workstations running directly off of the main 48 port switch, and 3 wireless relay stations. All of these workstation speed test good at the top of our internet speed 40Mbps up and down, and are connected at a 1GBps connection to our server.
Now for where I have the issue, we have a 185’ Cat5e cable coming from the main switch to a (Net-gear 24 port=10/100/1000=1GBps switch. The workstations that are directly running off of the 24 port switch are dropping in intranet and internet speed. Our internet speed should be at 40Mbps down and 40Mbps up. But anything after the 24 port switch, like the workstations are running at speeds of 4 to 5Mbps down and up. Also the light on the 24 port switch were the main cate5e line from the main switch plugs in is yellow, telling me its 100Mbps connection not a 1GB connection. This should be a 1GB connection as the every the behind it is a 1GBps network.
Both Switches are new, the 24 port is brand new and replaced a 24 port 10/100Mbps switch. So to make this shorter when I have the 24 port 100Mbps switch in this location and it all worked fine, it was not until I installed the new 24 port 1GBps switch that this issue raised its head. Any Idea’s or help would be appreciated. I also had a lot of trouble getting the new switch to work at first all lights were on where it had plugs into it but none of the workstation would connect or get there a IP-addresses assigned. It was not until a friend of mine pulled the incoming line to the new switch and plugged in an inline 48volt power supply that it jumped started the system. This should not have to be inline this power supple is for powering an ip-cam or wireless relay box should not be needed for an intranet network to run. Any way I unplugged it and we still are up but at the slow speeds and in the main incoming line is still flashing yellow at 100Mbps not Green for 1GBps.
Things I have tried all ready
A. Followed 185 foot cat5e cable looking for hard bends or cuts. Nothing found.
B. Looked to make sure all ends of the cat5e cable were wired in the same pattern and the right way, looks good to me
C. I have pulled the main incoming cable from 24 port switch and ran a speed test and speeds are up at 45 to 50 up and down.
D. I have walked all workstation connected to 24 port switch to check if any are pulling high bandwidth such as p2p software or any other high bandwidth activity , nothing
E. We do have 4 wireless relay boxes running off this 24 port switch and I checked for high bandwidth activity on those ports and it looked good. Also everything is set up the same all
F. the way around the network as it was back when they had the 100Mbps switch in place. And it worked fine. The only change is the new 1GBps switch.
G. Looked into the length of the 185 foot cat5e cable going to 24 port switch and it looks like that is good as well, 293 is the max length for that cable without a repeater.
