RE: Testing Device connection Speeds

Hi Guys,

I feel that is is worth picking the OCUK brains on this...

Where I work has recently moved to a new office, and I have done quite a lot of the networking side of things myself (Switches, patch cables etc...) However, I feel this is something I should already know, but in all honesty I draw a blank.

So the printer we have (Richoh Aficio MP C6501) is now really slow at transferring scans over the network. Now, I can only assume that this is a bandwidth issue, so would like to test how much bandwidth the printer has. and can utilise.

Now how would I go about that?
Also, any further suggestions on what could be causing the slow speeds of transferring 18MB files? We are talking 5-10 minutes here, which is a ridiculously extended amount of time.

Update: Turns out, when I disconnect the printer from the switch, and connect it to a wall outlet, the connection is really speedy again.

:confused:

As to why this would be the case, as the wall connections go to the same place I believe. We are having our managed IT provider in tomorrow to assist with a couple of other bits, so will run it past them, as I am unsure of how they have configured it.

Do you think they would have any diagrams of how they have structured out the network?

What make/model switch? What else is plugged into it?

russell664 · 14 Oct 2015 at 18:53

The switch concerned is a HP Procurve 1810G-24.

We have other office PC's patched into the same switch, which is then networked to the Server Etc...

Around 23 other PC's networked into it. However, upon testing when everyone is gone, the speed issue remains when plugged into the switch.

Well 22 PC's, as the switch needs a link elsewhere...

Printers port manually set to 10mb or 100mb?

bledd · 14 Oct 2015 at 20:11

Bad cable?
Try another switch port, patch it into the'good' one

russell664 · 14 Oct 2015 at 20:35

Tried a different cable to the same port in the switch. I will give another port a go tomorrow.

It certanly wasnt the cable, but it was previously using an extender, which i thought might be contributing to the issues, but turns out it had nothing to do with it.

I have tested the connection to the server and we are getting 10gbs from the swutch to tbe server, so things look good on that front.

russell664 · 14 Oct 2015 at 20:35

To clarify, the print server is set at 100mbs, i checked on the system log to confirm also.

? What do you mean by extender

I assume you mean 1Gb/s

Might be worth forcing the switch port to 100mb - might not be autonegotiating properly with the print server (what model?)

Does the system log sat what the duplex sets to for the nic?

To set this correctly it needs to be either 100/full at both ends or auto at both ends. A mixture will result in poor performance.

Sorry for the late update on this.

both sides of the switch are manually set at 100mbs, on both the printer and the switch.
We have had a new switch (1gbs) fitted to help with the growth of the business.

The concerned printer now has it's own patch cable directly into that, and everything is working better than it was initially.

Thanks for the help fella's!
