So I just got to my summer house and connected to my wifi network (Comcast). At first, it was horrible, on speedtest.net I got less than 1mbps. But then, miraculously, it goes back up and on speedtest.net it shots to 15mbps.
It keeps fluctuating between these two speeds and remains a the slower speed for some days and then some days it stays fast.
It doesn't matter what location I am at either, it can be fast in the same spot it was slow before.
The only explanation I can come up with is that it is my ISP **** around but my friends laptop gets good speed.
Here's my netbook for reference.
