Fiber Optic Leased Line

[people3]

HI All,

We have just had a 10mb Leased line installed (over fibre)

Our download speeds are fine 10mb but our upload speeds are about 3mb. We have contacted our service provider and they say that the line is set to be 10mb up and down.

They have logged into our router and according to the engineer we are getting lots of CRC error on the lan side.

To test we have removed all bits of kit and just plug a laptop in we still get a low upload speed.

The only thing we have noticed it that where the fibre comes into our building there is a 12db filter on the RX side and nothing on the TX, could this be causing the issue?

This sounds silly, but make sure you are using good cables.

Another thing is to set the interfaces manually to 10mb instead of auto-negotiate.

How does that do?

What kind of router?
