Router:  TL-ER7206 v1.0 (firmware: 1.2.0)

Switches:  TL-SG3452P v1.0 (firmware: 1.1.1)

                 TL-SG3210XHP-M2 v1.0 (firmware: 1.0.6)

                 TL-SG2008 v3.0 (firmware: 3.0.2)

APs:  EAP660 HD(US) v1.0 (firmware: 1.1.0)

 

Specific devices affected are the following.

 

Wired to the SG3452P switch:

-Western Digital MyBook drive

-WD MyCloud drive

-Denon HEOS AVR-S960H receiver/amplifier

-various desktop computers

-various TVs and streaming media devices

 

Connected wirelessly to the APs which are connected to the  TL-SG3210XHP-M2 switch:

-various Apple iPhones

-various laptops

 

 

Phones (on VLAN1) using the HEOS application cannot find the HEOS device (on VLAN3) unless the phone connects to the VLAN3 wifi.  Computers on any VLAN other than VLAN1 cannot connect to the network drives that are on VLAN1.  I've attempted to ping various devices on different VLANs and they always fail.

VLAN3 is for media devices

All devices in each VLAN are being assigned an appropriate IP address. They can all connect to the internet. There haven't been any other issues with connectivity. 
 

All firewalls on the router and computers have been disabled during testing. This has not resolved the issue. 
 

I have seen web error 403 when trying to access the web interface of devices on different VLANs. 
 

Pinging any device in a different VLAN always fails. 100% loss of packets. 

Actually...  I tried again and pinging some devices is actually coming back successfull.  The WD MyCloud drive is returning the 403 error.  A quick internet search on that shows that specific device will not allow communication from any other subnet by default (regaurdless of VLANs).  So that explains the issue with that specific device.

 

Give me a day to rearrange devices and retest this problem to verify it is still an issue.

Correction:  I can successfully ping devices in other VLANs and can access their web interfaces (for those that have them).

 

Maybe this should become a new post now that my problem is more specific but I will ask it here first.

 

1.)  The real problem is accessing a Denon AVR-S960H audio/video reciever (on VLAN4) via the HEOS app from a mobile phone connected wirelessly to VLAN1.  Internet searches make this seem like a common problem often resolved using mDNS and IGMP proxy settings.  I am unable to find any settings like that on any of the TP-Link equipment im using.

 

2.)  In the switch settings under L2 Features > Multicast > IGMP Snooping, should each switch have IGMP snooping querier enabled and if so should the querier IP be that of the router or another device?

  @Fae 

The multicast settings seem to be the primary fix according to other HEOS users. What is the proper configuration of multicast queriers with multiple vlans?  Should a querier be enabled on every vlan, none of them, or one of them?  What should the querier IP address be with my setup described in the original post?

 

Thanks again for all your help!
