Hi all,

Can anyone recommend a good router to use with the Super Hub 3 for 20+ devices connected at a time. We have 6 people in our house, 3 working from home.

We only have the M100 package, but speed isn't the issue. It's the constant disconnects and occasional router reboot, which I presume is from all the devices.

Thanks,

Andy

Before you even think of purchasing your own router, which many people on the board imply fixes ALL problems, you need to check out your circuit.

Go to 192.168.0.1 and post your up/downstream stats and network log. 

If all your devices are WiFi connected it’s better to get a good quality Wireless Access Point than a router.

Sound advice from @Tudor , although I'd say go for a mesh wifi system if you want to improve wifi across the property for many users.

But something additional to consider is whether you're saturating your upload?  As a yardstick, anybody doing a corporate video call is using around 2.5 Mbps, anybody doing HQ videocalls is using around 5 Mbps, and anybody doing Twitch streaming is probably using 5 Mbps. And anyone doing file or data uploads will use as much bandwidth as the router lets them have.  Under some circumstances the household could be trying to exceed the 10 Mbps upload speed associated with an M100 package.

But before jumping to any conclusions and giving VM more money to increase your speed, upload those hub status figures so we can look for any noise or power faults, and also setup a BQM.  That will show if there's anything sinister going on with your VM connection.  Post a link to a live, shared graph here and we'll see what's happening.  Usually needs to run for 24 hours before we can draw reasonable conclusions, but the live graph will continuously update so you can do that immediately.

I'm a little new to all this but is this what you need?

So your downstream levels are too low and the upstream levels are borderline too high.

[jbrennand]

The RS errors may indicate a "noise" issue as well.

So switch the Hub off and unplug it for a few minutes and then start up. When done, check back in the settings and ensure that the RS error counts have all reset to 0. Then check every hour or two for the next day or two to see if they start reappearing - they shouldn't. If they do (particularly the postRS ones) you have a problem (noise) that only a Tech visit will sort ( at the same time as they adjust the power levels!).

Hi,

Here's the link to the BQM. Not sure which one you want so I posted a few.
