Nighthawk C7000 v2 slow wifi speed
I recently replaced my comcast rented modem/router with the Nighthawk C7000 v2 AC1900. We get 400Mb down the line from comcast. Previoiusly able to get ~370 over wifi and over 400 with ethernet. The nighthawk provides for ~200 over 5g wifi. I've tried factory resetting but no changes. Any idea why the Nighthawk isn't consistently allowing for speeds over 200?

Hi ooglykraken,
Good day!
Welcome to NETGEAR Community!
Thank you for reaching out. We are sorry for not being able to get back to you immediately on this one due to the backlogs in the system. Are you still having the issue? Are you getting consistently 400 Mbps internet speed when wired to the Netgear Cable gateway? Are all of your wireless devices getting the same internet speed( 200Mbps on 5 GHz)?
Please do not hesitate to let me know if you need further assistance.
Regards,
Oliver

Same issue here. I have Sparklight and am supposed to get 600 down / 300 up. On a wired connection I am only getting ~150-175. Sparklight has done remote diagnostics and says everything looks fine on their end. I have restarted the modem. They suggested talking to Netgear support but of course the normal warranty/support has expired so I am trying here. Really bothers me that I am paying for 600 and getting 150! They are coming out tomorrow but I suspect this is going to be a modem/router issue. Firmware is current according to the app. Any suggestions? I have never gotten great speeds but I didn't think they were this bad and testing on two computers shows that wifi speed is about the same and they should obviously be slower than wired. Help?!?

What devices are you speed testing with? Wired or wireless? Wired is preferred for speed testing.
Wireless, you not see much over 300-400Mpbs on 5ghz AC however that depends on wifi devices design and support as well.
Be sure you are connecting to 5Ghz radio for wireless speed testing.
Please post a copy and paste of the modems connection status page.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to power OFF the modem for 1 minute then back ON.

I have Xfinity, had it for years. I have been renting XFi modem, I have the 600MB speed package, and I religiously got over 600 MB as long as I was using the 5 GHZ wifi, and yes thats wifi. Today I decided to buy this modem to save money, it clearly shows it is capable of handling my speeds, so I get it activated and have my rented modem unactivated, and I too get max Wifi 240 MB down, no matter what device I am using, and you cant say its the distance my devices are away because I literally was getting 650 MB over WIFI right before I changed the modems, exact same computers, exact same phones, but now I get Max Wifi on 5G at 240MB and Wired it maxes at 400MB. I see the exact same issues others are having, but I can verify it must be the modem, or the config file they send to it as my devices were already verified getting the 600MB speed with Xfinity's rented modems. Is this somethinf Xfinity is doing because they do not want people to buy modem's? I'm sure they do not like that, they would much rather ream you for $14 amonth. I have had service for over 15 tears, Im sure you can add. So I am very upset and do not know what to do. This might be a class action lawsuit in the making.

I'm happy to report that I have finally got things working as they should have been all along. I haven't tested the wired connection, and probably won't at this point, but I was trying to retrace my steps to avoid having to wipe the system and start with a fresh install of Windows 10. I had forgotten about one change that I had tried early on in this troubleshooting - something that was suggested on several sites if you google "slow internet windows 10" or similar. That is, disabling windows auto-tuning. I had forgotten about that, and so today I set it back to normal and just like that the 150-160 Mbps download wall was gone - I'm getting 600+ Mbps downloads using the A7000.
I think I fell into the trap of installing things too quickly from the vendors of my PC components, without being suspicious enough about what these "tools" would be doing. I honestly did not determine exactly which program was causing my horrible initial experience of sub-20 Mbps speeds. That lead me down the road of trying any and all suggestions I found that claimed to be solutions to windows 10 internet speeds, and not keeping good track of what changes I had made.
I'm not really sure why so many people feel disabled the auto-tuning function will increase speeds - i literally found 10's of pages that all said to do this, and they all seemed sure it would only help, not hurt your performance. Clearly that isn't always the case.

Glad you got it working. Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.

Thanks for sharing. MY setup is the latest version of MacOS so the Windows info unfortunately does not help me. I have pretty much given up and resorted to slower speeds than both Netgear and my ISP (Sparklight) say I should be getting. :smileysad:
