This isn't the best place for this thread, but I couldn't see any other area that seemed to fit better.
Basically I want to know how to tell what the problem is with my internet connection. I live in Denmark and have a 12Megabit cable connection, connected to a motorola surfboard cable modem, which in turn connects to a linksys wireless router. My PC plugs into the router, and my laptop connects wirelessly.
The modem is over seven years old now, the router maybe 18 months to 2 years. Up until about a year ago I had no problems, the connection was fine and reliable. I used to do a speed test online and it always came out at the right speed. But some time in the last year things started slowing down and getting patchy. It was still mostly fast enough so I didn't concern myself overly, but now in the last month or so things have started getting a lot worse.
In my online game (Guild Wars) I'm getting a lot of lag, where I used to get practically none. Download speeds for webpages are often fine but often lag a lot as well. When I download torrents things sometimes get up to very high speeds still, so I think the potential for a high speed is still there. Running the online speed test now produces much lower results. I ran the test twice just now and got 5.3Mbit and then 4.7Mbit(should be 12, remember). We have in fact received notice that our speed is being increased to 15Mbit some time around now, and I would think that problems with that might be the explanation, except that the problem started long before.
So my question is, how do I find where the problem is? I can contact my ISP of course, but I have no idea if the problem is at their end. I kind of suspect it's not, since if they had a problem they probably would have fixed it by now. The slow speeds show up on both laptop and PC, so the problem can't be the wireless connection. The modem seems like an obvious culprit as well, except it seems odd to me that it should just slow me down rather than just go kaput. But then, I don't know what I'm talking about really Finally, it did occur to me that someone could be piggybacking on the wireless connection, but nothing shows up on the network list that shouldn't be there, and I do use WPA2 encryption and a password, so that seems unlikely too.
Vista Home Premium 32bit on both the PC and laptop, in case it's relevant.
Thanks in advance
EDIT: I just tested the speed once and then took a short break and then twice more. The first time I got 5.75, and then, after a short break. 15.3Mbit and then 13.8Mbit. So very sporadic, and still able to reach full speed when it feels like it.
