Number of simultaneous users on OpenDNS Home

[philijer]

Dear all,

For a few days now my home welcomes everyday up to 14 children homeschooling at the same time, each with one laptop and potentially a mobile phone. 
Hence we can have up to 20 to 30 devices connected at the same time.
They connect to remote classrooms to follow internet base courses with live teachers. They use some kind of conf call video sharing to do so.

In the morning until they arrive and connect to their virtual classroom, I can work fine at home and internet is great (100M/s Fiber). In the evening, I can browse without any issue with all my family (3 to 4 people at same time).
Yet, once all children connect in the day, internet goes slooooooooow with regular disconnection from their classes. I can also feel it on the global internet browsing by my own. Children go crazy as they can not work normally, lose time and get bad remarks from teachers.

We are all on Wifi with a single Box ZTE F660.

Is their a potential limit to number of simultaneous users and bandwidth for Home users ? Would OpenDNS limit numbers of requests for Home usage ?

I do need to securise my internet access with all these children under my responsibility.

Thank you for your help !

This is not how DNS works, and there are no "simultaneous users on OpenDNS Home".  DNS doesn’t have a user limit and is not related to connectivity, therefore your problem is unrelated to OpenDNS.  DNS is the phone book of the internet, not the phone lines.

The problem here is with the bandwidth of your internet connection, i.e. these are limits set by your ISP and the DSL/cable technology being used.  All users must share this 100 Mbit/s.  Especially video streaming is resource consuming.  A home internet connection is not thought to serve up to 30 devices with video streaming.

Possible solutions are:

• Get a faster internet connection or multiple parallel internet connections.
  Contact your or another ISP to see what they can offer.
• If this virtual classroom is the same for all participants, then use one computer and a beamer/projector to be used by all for viewing.
  Contact the supplier of these classes to see what other ideas they may have for your scenario of up to 14 children.

Thank you for your answer.
Well I know DNS is some kind of Directory for internet sites.
Yet as OpenDNS offers a filtering I was wondering if this special service could be "moderated".

I am more now examining the limitation due to my routers that could not handle the number of children.
It is using SU-MIMO, i will buy a MU-MIMO 4x4 router.
Hope it will help.
