Disconnected from maplestory after 30 seconds.

Two days ago I lived at my old house. My set up was a modem and router, and maplestory worked fine.

I moved into my grandmothers within the last 2 days. My internet provider applied my internet/tv package to my grandmother's house. I plugged in my old modem and router. I try playing maple, and I consistently get disconnected and MS closes itself after 30 seconds to 1 minute of play.

I then bought a new modem/router combo, where it is both built into one. I set it up. I try playing maple, same exact thing.

I then call my internet provider for some assistance. They send a guy out here about 2 hours ago. He replaces some coaxial cable, because the TV cords under the new house and running to the modem were over 8 years old.

So he does that, and leaves. I try it just now, same thing. I did a speed test, I have 16 MB download, and 0.41 mb upload to the nexon servers, in San Jose.

Weird thing is, I also experience weird just drops in data, where if im loading several web pages theyll slow to a crawl, stop, and then load everything real quick.

Anyone got any idea whats wrong?

A quick google seems to indicate that it would be an issue on their end/their hardware, assuming that since you already tried most common troubleshooting tips and even had a tech come and replace the line. I'd contact them again and see if they can check their connection on their end.

The most frustrating part is that this is only happening with maple. Starcraft 2 and League of Legends arent affected at all. :/

Sounds like something with your ISP is affecting the packets being sent too and from maple. Or a port on your router might be blocked.
