Issue with internet jitter/dropout - eviltoast

Hi all, first time posting for tech support on lemmy!

I’ve recently switched ISPs to now have a gigabit connection at my home, but we’ve been experiencing some weird issues with it. When i run a speedtest, I get my full gigabit (or close enough) speeds and most of the time it works perfectly. But ever so often, it just completly drops all packets. When downloading a file for example it can randomly drop the speed to 0 b/sec and you have to restart the download in order to get it working again. Same with website loading, when it happens when loading a website, just half of the website gets loaded and I am missing images/styling/etc.

Now I run my own EdgeRouter X behind my ISP provided router. I have a nagging feeling this could be causing my issues, but with my previous ISP I was running the same setup and it worked flawlessly (albeit with a different ISP provided router).

Have any of you experienced something like this before?

Edit: thanks for all the quick responses everyone! I will look into your suggestions and update the post if/when I’ve found my solution.

Edit 2: Fixed the problem. As always, when in doubt, it’s the DNS. My ISP router did not come with any DNS settings preset. I set it to the same DNS as my EdgeRouter and my problems went away. I hope this helps some of you facing the same issue. Thanks for your responses!

    It could be something silly, like DNS on the edgerouterx still being set to the old ISP’s.
    It could be that the ISP is still stabilising your line.
    It could be that whenever the connection drops and reconnects upstream from the ERX, the ERX takes a few minutes to re-establish (or if your provider does not give you a static IP, recover from the external IP change).
    Make sure you haven’t done something crazy like set the external port of the ERX to the same IP as the ISP equipment.

    If you don’t have anything very complex, you could nuke the ERX and restart everything.
    Or if your ISP runs on PPPOE, you could try bypassing the ISP router. (And also, if you’re using pppoe, make sure your MTU isn’t too high)
