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!
