Hi,

We are getting speeds of about 200-250 - this can be resolved with a modem reset (its in Modem Mode) but after a few hours/days the speed drops again. Upload speed seems to be stable.

We upgraded from M250 to M500 but got better speeds on the old tariff.

Online service checks says that there isn't a problem. 

We use Unifi equipment with CAT7 Cables so I don't think our network os the problem and internal LAN speeds are normal at all times.

Any help or Suggestions.

Checked today still only getting speeds of 200Mbps

Wonder if someone can check my hub stats

Hi @nridgway,

Welcome to our Community Forums and thanks for posting.

Sorry to hear you are having problems with slow broadband speeds.

Have you carried out a speed test on a wired connection?

I have taken a look at your account and there's no area outage that could be causing this. I can see you also rebooted your hub 23 hours ago. 

Are you able to take the hub out of Modem Mode so I can carry out further diagnostics?

[nridgway]

Have you carried out a speed test on a wired connection?

Yes - I can also do a speed test directly from our router as we use Unifi equipment. After a modem reboot it goes to normal speed but then drops - currently getting 200Mbps

Are you able to take the hub out of Modem Mode so I can carry out further diagnostics?

I an only do this at an arranged time as we the network is setup to use it in modem mode so will need some changes.

Additional Info

When we had trouble before the engineer said that they had taken the cable from the wrong cabinet - about 300m away. He said it was strange as they is one about 50m away, which they said could be causing problems.

Thanks for popping back @nridgway

Do let us know when you are able to put the hub in router mode and we can take it from there 🙂
