Hi folks, can anyone advise me if it is possible to access the B3 network settings to configure DHCP to Automatic instead of Static? Thanks!

The key to this whole thing is that you have two DHCP servers running. That means you have two networks that will not talk to each other. This is what Mark pointed out.
 
We need you to describe every network component you have from the router connected to the ISP and then all mesh nodes or extenders. Please tell us how each computer/Brennan/Sonos connects to the network, WIFI or cabled and to which device is it connected.
 
How many SSIDs (wifi networks) do you have when you connect? If they are all the same name then it will be difficult to figure out what is connected where. When we see the hardware list for your network we might be able to figure out what device needs a configuration change.

Thanks Ray, I think I've identified the source of the problem. I have a a TP-link mesh wifi system to boost wifi throughout the house. Not sure what I should do next to resolve the problem

TP-Link's suggestion is to turn off the DHCP service in the ISP's router, and connect everything to the mesh. If any of the mesh nodes has an Ethernet jack and is near enough to the B3+ you could just connect the B3+ to that node with the Ethernet cable. Or put a mesh node close enough to the B3+ so that you can use wifi.
 
The alternative is to put every one of the mesh nodes into "access point" mode, and let the DHCP service in the router provide IP addresses to every device.

There is a lot of information in the Knowlege Base section. This includes a section on networking with the Brennan - Knowledge Base list of articles.
 
For this problem what you want to do is to first identify the router that is connected to your ISP. That is the only device that should be running DHCP. Then go into your TP-Link mesh nodes and with the help of the manual, disable the DHCP server in those nodes. What will happen then is that the MESH will pass all DHCP servers back to the router connecting to the ISP. Then all devices will only have access to one network. The TP-Link devices will be acting as Access Points instead of routers.

Thanks Mark, a wired connection between the B3 and one of the mesh nodes has solved the probem. Really appreciate your help.

The wired connection to a mesh node has addressed the SYMPTOM -- that the B3 and Sonos systems were on different networks.
The PROBLEM is that you had two DHCP servers running. You can solve that by turning off the DHCP service in the router.

Please note. If you turn off the ISP router's DHCP then you need to turn off the WIFI for that router and ONLY connect one ethernet cable to the master MESH node. Do not use the ISP router for anything else other than the MESH router.
 
The reason is that when you turn off the DHCP you must setup the ISP router as the gateway only. If you connect anything else directly to the ISP router, it will have a direct connection to the internet and ask the ISP for an IP address. It should fail but if it does not, the box will be wide open to the internet. You would still need to configure the router with an appropriate internal IP address.
 
For simplicity I will always recommend the MESH's DHCP server be turned off. This is sometimes called bridge mode.
 
Recovery is also simpler if the DHCP server is at the ISP router as only one machine needs to power up first.

The only reason I suggested the other way around is that that is TP-Link's recommendation when using their Deco mesh.
Doing it your way is safer for the reasons you state. TP-Link calls that "access point mode", so if you ever look in their documentation that is what you should find.
