Every 5-10 minutes or so, I'll experience a complete gap where I have no connection whatsoever. I've had it last from a few seconds to a few minutes. this is bugging me since it happens regardless of the time of day. My area is heavily saturated, but even during the morning when I actually do get the advertised speeds, my connection just shuts off completely. Would this be due to a bad modem? I'm using the wireless modem (DPC3825) supplied by Shaw.
Awkwardly enough, my computer still shows internet access. It doesn't flat out say I have no internet, but my browser stops loading pages and Skype disconnects as well as any other internet-using programs.
On another note, I've already ruled out the fact that it could be wireless; I moved my modem near my computer and connected via ethernet, and it dropped almost immediately after successfully connecting. My internet has come back for the time being.
Edit: It happened again less than 5 minutes ago and lasted quite a while. I'd say about 3 or so minutes this time. During that time my modem seemed to stay the same, no lights changed.
Edit2: It seems to have been doing this less severely, but my connection still has episodes where my ping will spike up to 500 out of nowhere and continue to jitter for a few seconds.
