My internet seems relatively fine. I play on a laptop, and I suffer no actual lag. However, I VERY regularly suffer random 90k errors that boot me from the game. This happens every day. Everything will seem to be going fine but then all other players freeze and my Sending/Receiving numbers become zero. It boots me to the menu. Attempting to press Start to get back in freezes the game, and literally the only way to close it is to disconnect and reconnect to the internet because that makes the game go 'hell no' and I can't select anything not on my taskbar so that's about it, bar restarting my laptop. I reopen the game, I can't get back in immediately because I'm still 'logged in'. This is incredibly frustrating.

This will happen several times, in bursts. Just prior to this post, I got disconnected from Ragnarok server 5 times in a span of half an hour, although this can be stretched out to be over 3 hours. There was a gap of about 10 mins between the 1st and 2nd, 5 mins between the 2nd and 3rd and the others were nigh instantaneous upon logging in.

This can occur during regular play and during dungeons. It also happens VERY often when initiating cutscenes, although this may be a coincidence.

I live in Lancashire, England and this has happened with ISPs Sky and Virgin Media.
