Damn we were 5 down and 2 up forever. Now, we are 70 down and 6 up. Can't even tell the purpose.
If you are 35 down and 5 up, it is your network.
Try the modem, get your speed.
Then try your router (good bet as far as upload)
Then try your switch (good bet -- maybe it's 10Mbps instead of 1,000Mbps.
Certain ports make a difference.
I doubt it's the server. But, try the speed test from there. Then run a speed test after running a cable from there to modem or router.
Remember, NIC cards should be 1000. But, generally they autonegotiate.
Make sure under your NIC properties, you go to Advanced, use the property Speed and Duplex. It should say Autonegotiation. If it does great. But, you may need to force it by using 1Gbps.
