unitd77 Posted February 2, 2021 Share Posted February 2, 2021 Just taking a quick google search for "slow XR300" came back with more results than I expected, but my issues seems to be a smidge bit different. I bought my XR300 last year when I only had 200Mb/s down knowing I would upgrade in the future, I paired it with a Netgear CM1000v2. I just recently upgraded to 1Gb internet service. I noticed my speeds are not quite up to snuff. When I run speed tests I get anywhere from 250Mb/s to 450Mb/s and it is different every time I run the test, but it is usually around 400Mb/s. I called comcast to double check the wiring to the house and the service. They replaced the old cable and verified that the modem is getting about 965Mb/s. I was able to directly connect my computer to the modem and see 945Mb/s (proves Cat5e cable I have is good). When I connect my XR300 in between the modem and my computer I get about ~400Mb/s. If I disable QoS I get about ~700Mb/s, better but not quite there. Setup is as follows CM1000v2->XR300->PC Things I've tried: Only computer connected to the network Network map table view shows 1000Mbits Full Duplex Monitoring statistics shows 1000M/Full status Firmware is up to date I have reset the modem and router several times Things I've noticed: When running a speed test I see 1 CPU core jump to 100%, but the other sits around 20% Speedtests are very random, before typing this post I was getting 400Mb/s, right before posting I got 600Mb/s. back to back runs usually stay fairly close, but different times of day are different performance. Speedtest.net the speed usually slowly ramps up to the final numbers, is this normal? I seem to remember it usually just sat at whatever speed my family had as a kid. WiFi test on my phone shows ~350Mb/s While the 400ish Mb/s is plenty for only me to use, I'm about to be getting roommates and I'd like to be able to have the bandwidth for all of us at the same time. Plus the whole "I'm paying for it, where is it" usual thing. Link to comment Share on other sites More sharing options...
Netduma Liam Posted February 2, 2021 Share Posted February 2, 2021 Welcome to the forum! Thanks for all this information, that's really helpful. Could you please try disabling IPv6 if it's enabled? Could you also please let me know the exact model of the Comcast modem/router? Link to comment Share on other sites More sharing options...
unitd77 Posted February 27, 2021 Author Share Posted February 27, 2021 There is no Comcast Modem/Router. It is a Netgear CM1000V2 Modem, and a Netgear Nighthawk XR300 Router. I tried disabling IPv6 under Settings -> Advanced -> IPv6, and got no difference. Still sitting around 480Mbps. Sorry for the terrible late response. thought my "notify me of replies" would send an email or something that would ping on my phone, I'll have to double check that now.

Administrators Netduma Fraser Posted February 28, 2021 Administrators Share Posted February 28, 2021 No worries! One step to try when you have time is to do a factory reset and doing make any changes other than the ones in the Setup Wizard and see if you notice the speeds increase. If fact this is probably the best idea so the router can adjust to your new connection. Otherwise, in Settings, start the setup wizard again but just go as far as the speedtest - what speeds does it show there? Link to comment Share on other sites More sharing options...
unitd77 Posted February 28, 2021 Author Share Posted February 28, 2021 I reran the setup wizard, not many options to change, and the speed test errored out. I ran a speedtest manually, and got the same speeds. ~511.63 Mbps down and ~41.94Mbps, half of what I should be getting down. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted February 28, 2021 Administrators Share Posted February 28, 2021 Sometimes it won't report the speeds but if you try it a few times it will - I'm really interested in that result if you can get it because that's a speed test directly from the router so it identifies a bit more where the issue could be.

unitd77 Posted February 28, 2021 Author Share Posted February 28, 2021 Well I was able to connect directly to the modem and get the 950+ speeds I'm expecting. I tried the setup wizard a few times to get to the speed test there and it kept bugging out and saying "www.netduma.com refused to connect" Kinda should be just an "speed test" line on the advanced settings tab, so I don't have to go through the whole setup each time.

Can you provide a screenshot of where it said that please as I've not seen that before. We're working on that in 3.0 actually - it's implemented but needs to be improved.

unitd77 Posted February 28, 2021 Author Share Posted February 28, 2021 I kept redoing the setup wizard, It kept opening up a minibrowser to the Netgear website asking me to register my product. I tried to through the minibrowser and I couldn't type into any fields, so I opened a chrome tab and did it manually, then went back through the setup wizard. I tried to sign-in to the netgear account and It at first said my password was wrong, then after resetting the password It would just show a spinning wheel and then nothing changes. It just sits at the login credentials and won't advance. I tried reloading the frame under right click menu. Not able to get to any sort of speed test. The next button located under the minibrowser just takes me to the DumaOS dashboard. I am unable/don't know how to manually redirect the minibrowser window to speedtest.

unitd77 Posted February 28, 2021 Author Share Posted February 28, 2021 I was able to get it to login. it just said success and left me on the netgear site....... no speed test. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted February 28, 2021 Administrators Share Posted February 28, 2021 The speed test should be a part of the setup wizard not part of that mini window - maybe it isn't active on the XR300 - do you recall seeing it do a speedtest whenever you first set it up?

unitd77 Posted February 28, 2021 Author Share Posted February 28, 2021 The only mention I ever saw of speed was setting the limits of the QoS. I feel like there was a speed test when I first set it up, but I have no idea where to find it. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted February 28, 2021 Administrators Share Posted February 28, 2021 Okay could you go ahead and do a full factory reset from the interface please and when you do the setup wizard, make note if it does a speed test and what results they are and then also see if the reset itself improves the speeds please.

unitd77 Posted February 28, 2021 Author Share Posted February 28, 2021 Factory reset, did nothing but erase my QoS balance. no change in speed. No speed test during the setup wizard. QoS limits defaulted to 1000Mbps up and down. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted February 28, 2021 Administrators Share Posted February 28, 2021 Do you have another router you can put between the modem and XR to then test the speeds in that configuration? Link to comment Share on other sites More sharing options...
unitd77 Posted February 28, 2021 Author Share Posted February 28, 2021 Not a router than can do gigabit. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted February 28, 2021 Administrators Share Posted February 28, 2021 In Internet Setup make the MAC address use the PC MAC address instead please and see if that works. Link to comment Share on other sites More sharing options...
unitd77 Posted March 1, 2021 Author Share Posted March 1, 2021 no dice. Changed setting to "Use Computer MAC Address" then all the addresses defaulted to 0.0.0.0s (Monitoring - > connection status) WAN IP defaulted to 0.0.0.0 and I had no internet at all. Tried rebooting and got nothing to work. Had to change back to default. Is this related to the CM MAC number I found under my Modems page? Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted March 2, 2021 Administrators Share Posted March 2, 2021 I don't think so now. There are really no other options we can suggest really that will boost your speeds any further. If you're not happy with the speeds you're getting then I'd recommend making a ticket with Netgear directly and if they have no ideas then try to pursue a replacement. http://support.netgear.com/ Link to comment Share on other sites More sharing options...
