Devices on Wifi not communicating with each other

[equalparts]

Hi there,

We had our fibre installed at our business last week (after 6-month wait).

The incoming connection is good and devices are connected to it - however they don't seem to be able to see each other or communicate with each other

For example, laptop cannot see wireless printer on the same network - we are a hospitality business which uses point of sale on ipads, and the ipads can't see each other

Help very much appreciated

Sounds like you need to contact VM Business https://www.virginmediabusiness.co.uk/help-and-advice/existing-customers/customer-area/

Yeah have tried that and not much help so far. Don't get much further than 'there is internet coming in, everything else is your problem'

As a guess when trying to connect to a printer try and ensure both laptop and printer are on the same frequency (eg 2.4 GHz). Splitting frequencies can help with this.

Check the IP address of the devices and printer, all should be on the same subnet for communication to would. The nnn.nnn.nnn part of the IP address shod be the same.

Thanks, is there a router setting that would put everything on one subnet?

Are you seeing IP across 2 subnets E.g. 192.168.0.xxx and 192.168.1.xxx ?

You mentioned business,  which Hub do you have ? It is a Residential Hub 3/4/5 or a Hitron model ?

Domestic Hub's do not have any way to control the DHCP ranges on 2.4 / 5 Ghz.

Thanks, I can see that all the connected devices are on different IP addresses, trying to work out the setting that changes that.

It's a CHITA router

We see domestic Hub 5 customers report the WiFi devices connected on the 2.4 and 5 Ghz bands can not contact each other. E.g. A laptop on 5GHz can not ping or print to a WiFi printer on the 2.4Ghz band.

Could this also be the same situation you have with the Hitron ?

The fix for this is to add a dual band WiFi access point or use a 3rd Party WiFi Router that can be configured with AP isolation disabled on both 2.4 & 5Ghz to enable the traffic to pass between devices on the WiFi bands.

Everything's connected to the 2.4Ghz connection - so essentially we can't use this a wifi router?

Thanks for the help it is appreciated
