R6700 AC1750 router does not allow Gigabit connections?
I just upgraded my cable Modem to a Netgear CM1100 that supports Gigabit connections. I have an R6700/Nighthawk AC1750 Smart WiFi router connected to it. My wireless speeds and wired Ethernet connections hover at 80 Mbps via the router.
I bypassed the router by connecting directly to the modem using a wired Ethernet connection and the speeds reached greater than 600Mbps as expected.
Do I need to configure the AC1750 router to support the Gigabit speed from the modem?
Thanks in advance for any tips or suggestions to resolve this issue.
The R6700 is gigabit capable.
What firmware is on it?
Did you ever try a factory reset on it with a clean install (not from backup)? sometimes old qos settings can cause issues.
have you tried replacing the cable?
Also, make sure you're speedtesting over a hardwired connection. wireless AC won't hit gigabit speeds wireless. Especially the 2.4ghz.

As suggested by plemans , I reset my router and now I get way more bandwidth than 80 Mbps like I did before.
But resetting came up with just 2 wireless SSIDs. And the Guest radios are disabled.
I'll try activating them again and report back.A follow-up question: will re-activating the bonding of the 2.4 and 5 GHz bands for QoS mess up the accessible bandwidths again?

This not bonding (link aggregation, LAG, ...) of the the wireless radios. Having the same SSID for all radios - what makes perfectly sense as an SSID does designate an access to one network - will allow the mobile clients using the best available connection, assisted by some basic mesh standard features. where the 5 GHz will perform well, it's very likely the clients use the fast 5 GHz radio. Where the 5 GHz signal is becoming weak, the clients can almost seamlessly change to 2.4 GHz radio - what is slower but has offers the better coverage.
plemans mentioned: "...sometimes old qos settings can cause issues."
So I experimented with the QoS option after I was able to get satisfactory speeds after resetting my AC1750 router. Note that after reset, my wired connection averaged ~ 600 Mbps and the wireless averaged ~ 250 Mbps.
When I turned on QoS, my connection speeds dropped noticeably from what I had before. For example, my wired connection was at 208 Mbps and the wireless connection was at 175 Mbps. These correspond to a 67% drop in my wired connection, and 30% drop in my wireless connection.
For an interesting article on Netgear routers and QoS see the following (published in 2018):
https://www.tomsguide.com/us/netgear-router-disable-qos,news-27675.html
Even netgears own kb article on qos only recommends it at speeds lower than 250mbps. Because it disables ctf (cut through forwarding) that is needed on those devices to hit gigabit speeds.
