I am experiencing slow / failed rendering of sites in the browser. The browser is saying no internet intermittently – sometimes it connects lightning fast and other times it is dead. You can see this behavior approximately by looking at the output from repeated pings. I just ping www.google.com

I am just letting the ping run for a bit then cancelling it. You can see it hangs about every 8 attempts. There is definitely a pattern. As the ping is running, I can watch htop
and everything is well below thresholds in total <10% of cpu is being used and memory nothing too.
Can someone point me to a troubleshooting guide? I am newish to linux, networking and know nothing about OpenWRT
