Inloggen in het modem en daar de Wi-Fi uitzetten.  De rest blijft gewoon werken.

Wifi op de V10 uitzetten om de wifi met Orbi's te regelen.

Sonos zijn eigen netwerk laten creëren zou ik niet aanraden, ik heb er zelf geen ervaring mee maar ik hoor vaak van veel kanten dat dit niet altijd even lekker gaat en schijnbaar een network loop veroorzaakt waardoor het hele netwerk er regelmatig uitklapt. Beter om dan alle Sonossen via de wifi te doen, als die toch overal helemaal goed is dan lijkt het me onnodig om nog Sonosnet te gaan gebruiken.

Sonosnet is juist bedacht voor situaties waar de wifi niet toereikend genoeg is en ik heb vaker gehoord dat het dus problemen geeft, niet alleen met KPN apparatuur maar ook met bijvoorbeeld Ubiquiti. 

Hallo @Lee81, welkom op het forum!

Mooi om te zien dat je het forum hebt gevonden om jouw vraag te stellen! ​​​​​​Ben je geholpen met de tips van @Joep1965 en @NHendriks?
Als je er nog niet helemaal uit bent, laat het dan gerust weten. Binnen onze community is er ontzettend veel kennis en er is vast iemand die jou verder kan helpen! 

Instead of starting a new thread, I thought of asking here…  My first post in this forum.

I have an Experia v10 modem and just added a Netgear Orbi Router after it, plus three satellites to solve wifi connectivity problem in the house. Everything works fine, except one challenge.

There is a wired connection to a simple network bridge/hub which connects to a few devices, one of them is TV receiver. If the LAN originates from Orbi, then I can use remote control apps for the devices as everything is on same SSID. But then TV doesnt work. If the LAN originates from Experia, then TV works fine, but remote control apps for the devices do not work because of not being in the “same network”

I know it is a long way of asking a short question, but considering me not being an expert, hope someone could provide some easy to follow instructions as applicable to my situation. Thank you. 

That sure is possible! I'm not sure about the settings in the Orbi that might make it possible but I do know a workaround of using two managed switches and creating VLANs. I'm not sure exactly how to set that up though, I have been looking for about 20 minutes on the forum but either I'm blind or my Google-skills don't apply here. @wjb might be able to tell you exactly what the best way is to set it all up.

Edtit: Found it! The explanation is in Dutch and is about a Unifi Dream Machine but the principle is the same: 

Thank you @NHendriks . Does this mean the solution must involve two switches? I am currently using only 1 switch/hub close to TV receiver, simply to connect multiple devices including TV receiver by cable. 

I could buy a switch and go through all of these details if that is the only way. I stand to be corrected, but I thought there could be a simpler solution here, involving DNS or DHCP settings. Thoughts?

For anyone else who may run into the above problem in future…. I found a solution and it has been working fine for more than a week…. the problem was simple , it was about both KPN router and Netgear orbi having DHCP on. I switched off DHCP on KPN modem and left it ‘ON’ on Netgear orbi. We use Orbi wireless for everything now and all wired connections originate at Orbi as well. 

Fine print: I had to update the subnet masks to distinguish them and there was a delay in some of the devices updating the info. If you run into similar situations, please search for keeping subnet masks separate for Orbi and KPN modem so that you can distinguish them. 

Thank you all.
