NightHawk CAX 30 slows until Factory Reset or config restore
I have experienced this issue with this router since buying it at Costco in July 2021. My firmware is up-to-date with version 1.4.10.8. I do not have any special port forwarding or access control con...
Thanks for the advice.
Unfortunately, I do not have an Ethernet adpater for my laptops. However, I can say that testing from 2 Dell laptops (1 is band newand a Galazy 21 phone (Wifi 6 conection) through the CAX30 using Speedtest consistently mirrors what I get on the router's console within +/- 20 - 30 Mbps from multiple testing and multple target servers. My laptop and phone are connecting through 5G from a distance of about 8 - 10 feet.
Again, I am able to reliably fix the slow speed within about 3 - 4 minutes by simply re-loading the saved config file and rebooting. We're talking about improving from 120Mbps pre-fix to a post-fix 400 - 500 Mbps speed in only about 4 minutes' time. The reliability of the fix proves out over across the 4 testing devices (including the router console).
I am not the only person to report this issue and the same fix. https://community.netgear.com/t5/Nighthawk-WiFi-Routers/CAX30-Slow-Internet-Speeds/td-p/2132543.
Anthing you can recommend?
I screen captured some tests for you to see I am not crazy. Each test is time-stamped.
1. I performed two "Pre-reset" tests. In the first test, I used Speedtest on the console and Speedtest running on my 5Ghz connected laptop simultaneously, wiht the laptop connected to my ISP as the test server. In the second test, I tested the console and my laptop connection simultaneously using a local university as the test server for my laptop.
2. I then re-loaded my saved backup config of the very configuration running on the router at the time of the tests. The screencaps are timestamped.
3 I then repeated the speedtests from the console and my laptop, with the laptop testing against the same test servers as before.
Result: I doubled my download speed within a few minutes by re-loading a backup config and rebooting. Again.
I get the same result if I perform a hard reset and reconfigure the router manually. It's just a lot more work.
See attached.
The screen captures from the previous post went bad when I edited the post. Here it is again properly:
