Xfinity gigabit internet service. Not getting gigabit speed to router when running speed tests from nighthawk app. Constantly having to reboot router to get WiFi/internet connection. Ethernet speeds are not what they should be either. 200-400 mbps instead of gig. I’ve factory reset everything and still cannot get reliable WiFi/internet. Spent hundreds of dollars on equipment that doesn’t do what I want. Praying a networking wiz has some setting suggestion that I am missing. Please help! Happy to share any logs that may be of assistance. Let me know what you need, thank you all!

Start at square 1. Its pointless to troubleshoot a router if the modem or line is the issue.1. What speeds do you get directly connected to the modem? 2. the R7960P has wan link aggregation. If you're using it, disable it. Link aggregation has had issues for netgear/arris/etc. its been problematic3. Take a screen snip of the modem's cable connection page. Make sure you get all the info from that page and post it here. It shows your link back to the isp (a snap shot).4. If you are speedtesting, don't trust the built in app's speedtest. i haven't found it even slightly reliable. Make sure what you're testing on is hardwired in and try dslreports.com or speedtest.xfinity.com The others have had issues saturating gigabit. 5. firmware on the router? Start at these and let me know results. Like I said, its best to ensure you have full speeds at the modem and then you move on to testing the router.

Mac or PC for your laptop? for either, make sure to reboot the modem. Mac:https://support.apple.com/guide/mac-help/connect-mac-internet-a-cable-modem-mchlp1460/macwindows:you should just need to reboot the modem with nothing connected and then connect the pc.

If you log into the modem (192.168.100.1) and click on cable connection, take a screen snip of that and the logs. Post that back here.And then speedtest it off the sites I recommended.

I can confirm I have all port aggregation disabled. thank you!! Make sure you're testing hardwired speeds from the router. Not wifi. Wifi is dependant on device, environment, interference, etc. to many things influence the speed and wireless AC isn't going to max out gigabit.

I'm saying a lot depends on many variables.1. devices. Not all wifi devices are created equal. If you've got a wireless ac phone but it only has a 1x1 antenna. its going to connect at a 433mbps link rate. the actual throughput over wireless is roughly 55% of what link rate is (rough) due to wireless overhead. Or if you're device is a wireless N device its going to have lower speeds. If you're device is a 2x2 antenna setup, it'll be faster. So devices matter a lot2. Environment. things within your home can block wifi. Plaster lathe walls, metal, foil lined insulation, and other things within your home block wifi signals and can lower speeds. 3. interference. to many wireless signals in an area create interference and can slow down speeds. 2.4ghz is more suseptible to this than 5ghz but they both can be impacted. 4. Distance. the further away you are from the router, the slower it'll be. other things influence wifi as well but those are some of the major ones. the key is that you're getting full speeds from the hardwired.

  plemans thank you so much for reaching out. When unplugging the modem from the router and going directly to my laptop, it doesn’t connect at all. I get the message “Ethernet has a self assigned IP address and will not be able to connect to the internet.” I agree testing the modem first is best practice, what can I do to get a working connection from the modem to the laptop?
