I’m setting up a Deco to-link Mesh Wifi; it’s asking for Connection Type (for ISP) and IPTV/VLAN settings. My ISP is comcast; they informed they do not have that information and directed me to contact Netgear since I’m using a Netgear Cable Modem Router.

Those details, some of which are down to the ISP, are important when you connect a router to the Internet.

The options are: 1. Dynamic IP, 2. PPPoE, 3. Static IP, 4. L2TP, 5. PPTP, 6. DS-Lite The IPTV/VLAN setting’s they’re ask for are: 1. Internet VLAN ID (1-4094), 2. Internet VLAN Priority (O-7), 3. IPTV VLAN ID (2-4094), 4. IPTV VLAN Priority (0-7). Might someone know what the values are for the Nighthawk AC1900, Model C7000v2, or how I can determine or find those values, please?

Most of that stuff is down to Comcast, so heaven only knows why they couldn't provide answers. You can probably get the details by looking at the settings in your existing modem/router.

If something else is asking for that information, then you may be trying to add another router to the network. That is a bad idea.

Two routers on your network can cause headaches. For example, you can end up with local address problems. Among other things, the other router can misdirect addresses that the Netgear router usually handles, such as routerlogin.net or the usual IP address for a router, 192.168.1.1.

This explains some of the other drawbacks.

So, tell us more about this "Deco to-link Mesh Wifi". Google can't find anything, but suggests that I want to find out about "Deco tp-link Mesh Wifi". Is that it?

If so, then you may well be piling router on router. In which case, you may like to dig a bit deeper.

Unless you have specific reasons for using two routers – to create two separate networks for example – it is often easier to use just one router and then to set up the second router as a wifi access point. Netgear advises this, as does just about every site you will visit.

It may be possible to put the modem/router into modem only (bridge) mode and then to use the second device as the router. Sometimes it is easier to put the second router into AP mode. But that has its own drawbacks:

A lot of people use an Orbi Mesh system in AP mode, especially if they have a decent router in front of it. Maybe the same thing would work with the Mesh system you own. Only you know which of your two routers provides the best features for your needs.
