Every 20-30 minutes, my internet seems to be unresponsive for about 10 seconds. I can easily see this if I'm running the `ping` command while it happens:

![pinging to 8.8.8.8, showing a good ping, followed by a sudden raise in ping time, then returning to the good ping][1]

Now, I have two routers on my network, both broadcasting the same network (with a different SSID).

I have this problem since a few months.

My `/etc/hosts` file only contains a few `127.0.0.1 mywebsite.dev` entries.

I'm using Yosemite.

So, is this an issue that must be resolved on my Macbook Air 2014 or on the router?
