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, showing a good ping, followed by a sudden raise in ping time, then returning to the good ping

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 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?

  • What is your Mac OS Version ? Are you using Chrome ? I too had the same issue when I was using outdated version of Google Chrome ? – Garfield Carneiro Mar 9 '15 at 12:37
  • I use Yosemite. I don't use Chrome, I use Safari. Both browsers have the same problem though, so it's not the browser. Console doesn't show anything like that. – Jeff Huijsmans Mar 9 '15 at 12:47
  • Do you have another device nearby which may send a signal disrupting WiFi every 30 minutes? – nohillside Mar 9 '15 at 12:56
  • It happens everywhere in my house. Even in the back yard. All the same issue, nothing changes. – Jeff Huijsmans Mar 9 '15 at 13:04
  • Try turning off Bluetooth and perform the test once again. – Patrick D'appollonio Mar 9 '15 at 15:01

In my case it turned out to be the router. It was an old 802.11g router that I replaced with a 5GHz 802.11n router. It works great now, no problems whatsoever.
