My internet speed when connected to my ISP's modem is 95mbps, when connected to the router it is only 8mbps, sometimes less.
I removed gadgets around it (i.e. Netgear Arlo base), moved it up high near the ceiling, and away from all other electrical interferences,. It has increased to 17mbps but still far from my ISP's 100mbps plan. I have tried both wired and wireless.
Not easy to find that, but it looks like it could be a "gateway", with a built-in router.
Does it have a bunch of LAN ports on the back? Does it also do its own wifi? That would confirm it.
If so, you are trying to add a router to a router.
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.
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:

Re: Speed is slower when connected to router R6400v2
Whether or not the "double NAT" clash causes your speed problem is unclear. It is just something to avoid that can cause various issues.
A quick test would be to put the R6400v2 into wireless access point (AP) mode. If speeds get back to what you expect, you will then have to decide which of the various options to go for, using your gateway as the router or the R6400v2.
