Well, this is my first time posting on this site. If I posted this in the wrong place, forgive me.
Well, I have a problem with my internet. About 3ish weeks ago my internet started randomly disconnecting itself for about 20-30 seconds. I'm a gamer, so it's really hard to get into stuff knowing somewhere down the line I'm going to disconnect.

I've never had this problem before, so I have no clue what to do. I have Comcast with a wired router. Could someone help me out please?
Thanks in advance, and again, I apologize if this is posted in the wrong place.
