Dropping 7 - 10mbps

ninetyten · 1 Sep 2017 at 07:34

Hi Everyone,

At my small business, I have a very basic internet set-up for the pc's. Essentially draytek router connected to phone line, then a 15m Cat5e cable connects an unmanaged switch to the draytek and from the switch 6 computers and a printer are connected.

Problem is, I generally record between 9 & 12 mbps at the router, but the computers come back as 2-3 mbps.

I thought maybe it was the wire, so tested a Cat6 shielded wire between router and switch and whilst that shown a modest improvement of 0.5mbps,that does account for the other 8 mbps lost.

Any suggestions would be very helpful.

Take the 15m cable that plugs into the switch from the router and plug it into each of the 6 computers in turn instead if you can. Do you see 9 or 3 Mbps on each computer? This might narrow down if the switch is playing a part or not. Also try removing all bar one of the PCs from the switch and see what speed you get on the remaining connected PC.

Did someone else set this up? Have they maybe limited each device in the Draytek to 2-3Mbps (to prevent one machine hogging all of the bandwidth).

Give as much info as possible

Could be many things..

Also, when you say that you get 10Mbps at the router, is this in the router web interface? or is it by connecting a PC/laptop directly to the router and running speedtest..?

Install the latest Draytek firmware, use the .rst version and this will factory reset it. Re-setup and try it again.

Also which model of Draytek is it? A lot of my older Draytek 2820's started to fail and have problems so I recently replaced the majority of them with 2860's.

Thanks for all the feedback and so you know I put the system in, so the draytek is running most of its options on default settings.

I have tested a single line and that still gave me a reading of 3mbps and I got the same result when I only had one device via the switch. In terms of testing the speed, that was recorded through a BT wholesale Speed test connect directly to the draytek with my laptop. If you tell me how, im sure i can get the information from the draytek.

So your laptop connected directly to the router gets full speed but a PC doesn't? Is that connecting via the same cable?

So When i test the router - i use bt wholesale, but when i test the pc's i use googles facility. I have just ran the same test, on the same pc within seconds of each other and I got the results below.

I'm a bit confused as to what you're doing. For a start stick to one speed test no matter which PC/laptop you are testing with. Post the different results and explain how each device is connecting to your router (e.g. Wired, wireless, via switch etc.)

What results do you get if you use BT wholesale on the PC?

ninetyten · 1 Sep 2017 at 13:45

If i use BT wholesale - I get the the speeds shown above - 12.19 down and 0.73 up

Which indicates that the PC is getting the same speed anyway so whats the problem?

Thanks for all of your help - it was one offending wire that was causing the slowdown - now it is resolved and in future, i will just use BT speed test - nothing else!
