router r6700ax - no wan connection (tech support issue)
Spectrum/Charter is the service provider.
I am using a rented modem.
Network cable comes from modem to r6700ax - then downstream ports goto all other places in the house.
If I plug my MacBook Pro directly into the cable modem - I get an IP address via DHCP (directly wired connection) (this is via a USB-TypeC-Ethernetadapter)
If I unplug the MacBook pro and plug the same cable directly into the nether r6700ax - no joy, no connection.
Netgear box constantly reports 0.0.0.0 as the WAN (intenet) IP address
Which indicates to me - the Modem is not responding to DHCP requests, or what the router receives is not acceptable.
What I do not have is the ability to "sniff" the traffic between the boxes - but it is as if the Charter/Spectrum box is not responding to DHCP requests.
I am stuck - Charter/Spectrum says: If it works with your computer plugged in - they are done - the system works, nothing more for them to do - data connection works at their data port. and the problem is in my boxes (actually, your netgear boxes).
Yes, I have power cycled everything.
Yes, I have validated the cable _ same cable between my Mac and the modem
In more technical terms: the "link is up" at the 1gbit ethernet level, but the DHCP portion is not.
The Spectrum website talks of supplying a "router". If you have ine of those your network will need tweaking to work with that and the R6700ax.
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.
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:
