Recent update "broke" wifi -> lan connection

I have a remote head to a radio I own. Up until very recently I could use it's wifi connection through Norton Core to connect it to the radio. Now I can not.

Mechanism is broadcast discovery information sent by the radio, which is rj-45 connected. This information used to be routed to wifi connections. Now it isn't. Consequently remote head can never see radio. Was there anything done in this area? Wifi connection does show as network name with the name of the network. The radio itself is network name LAN.

Again, some weeks back, this used to work.

Re: Recent update "broke" wifi -> lan connection

Further information ----

On the LAN side (radio) I see UDP broadcasts flowing

On the wireless side, in this case laptop, from the identical source IPADDR I see no broadcasts arriving.

On the same laptop, with a lan connection, I see the broadcasts arriving.

This is a Norton Core issue and it's a new one regarding passing broadcasts from the lan connected devices to the wifi connected devices.

What changed and is there a way to effect the same outcome without waiting on a router software fix?

Thanks

Re: Recent update "broke" wifi -> lan connection

Hello Walt. First off what OS, version and build are you running (if Windows 10), otherwise what OS are you running? What Core app are you using, Android or iOS and its version? And what is Core for its firmware version? When you said "remote head", what device and type are you referencing? What is the setup you have for your network and Core? Looking forward to assisting with a bit more info to go with.

Re: Recent update "broke" wifi -> lan connection

Hi,

   First off, I am not a noob. I've been in software engineering 45+ years. To answer your question Win7 and Win 10. This used to, maybe a month ago, work. Here's the scenario.

Server: Linux LAN connected. I mean that in two senses, According to Norton core the name of the connection is LAN. I think this is important.

Client Win10 and WIn7 wifi. The name of the network is wireless-5g.

Flow..

Server app sends a broadcast to 255.255.255.255 every second annoucing itself, it's IP address and other info.

I see this via wireshark on my lan.

The client listens for packets on the same port as the server is broadcasting. From the broadcast message it constructs a server object and issues a connect() to it.

On the wifi client via wireshark there are NO broadcast messages received.

The IP address is 172.16.x.y so it is, by definition non-routeable beyond it's local area network. I get that. HOWEVER the wireless-5g, even though it was assigned by Norton Core a different name is, in fact, in the same class B network..well, sort of being that 172.16 is common between the two "domains". The broadcast should be passed between the LAN network and the wireless-5g network. It is not.

So what's happened in the last month or so? Norton Core was updated. My belief, at this point is Norton Core was broken as relates to broadcast messages.

If I connect the clients via RJ-45 all works fine. It's the passing broadcasts across lan->wireless

What are your thoughts? And thanks for getting back to me!!
