My internal network speeds has slowed down to 5mb/s...

[AndyD2k]

For the last month, my speeds have been really slow in between PCs. Nothing really has chanced on my end so I'm not sure what is going on

1) I've tried connecting everything directly into the router (I'm using switches) and that doesn't help

2) I tried changing the NICs (each PC has two)

3) I tried testing the network cables and everything seems to be ok there. Though, admittedly I bought a really cheap one off of Amazon so who knows if it's testing the cables properly

4) Reverted back to official firmware

5) I get max speeds externally

Anyway, I'm stumped. I normally would see speeds around 60MB/s. Now I'm maxing out around 5MB/s.

Any advice?

Bottleneck could be how fast once of the PCs can read/write from whatever hard drive you're transferring data from. Is one of them nearly full? How fast are the disks?

Basics first. Connect just one device and test. Then connect another and test.

We've had two instances where a bad cable or network port took down our network at work. It was very odd but pull the cable and everything is perfect, plug it in and everything slows or stops.

Have you installed any updates recently? I've also seen windows updates take down network interfaces for servers/computers. Specifically anything that binds to the nic like .net 3.5/4.

Mushkin, you're right that it can be my hard drives bottlenecking but I've been using the same drives for a while now. Never seen these speeds. But to answer the question, all the drives are green drives so will be slower.

Saratoga, I'm starting to think it's the cable too. That or the router. I'm going to order a new cable to replace the 35ft one that connects a switch to the router. I bought some crap cheap cable tester but I don't think it's reading things properly
