I'm using a Macbook Pro and having problems with the wifi network at home. Every 20-30 minutes, I am unable to connect to the internet although I can login into If I turn the wifi (on the Macbook) off and on, I can access to the internet again.

The strange thing is that this doesn't happen to other devices at home; and it doesn't happen if I use my Macbook in other places (e.g. at work).

So what are possible causes? How can I troubleshoot this problem?


  • Home wireless router has the latest firmware? – Dan May 6 '15 at 8:43
  • See signal strength, if the signal is low sometimes the devices cut connectivity, when you turn off an on you forced it to reconnect – emirjonb May 6 '15 at 8:46
  • I'm inferring a lot here, but you say you can't access the Internet. I assume, you're trying to access fully qualified domain names, like www.google.com, as opposed to accessing the non-routeable IP address OS X has been notorious for DNS problems for the last couple of releases. Cycling WiFi seems to restart mDNSResponder or discoveryd, depending on your flavor of OS X. – MMB May 6 '15 at 18:47
  • @Dan Yes, the firmware is latest. It is automatically updated as the router is modem/router combo. – Fabian May 6 '15 at 19:44
  • @MMB I think it has something to do with DHCP lease between the router and the Macbook. If I renew DHCP lease, the connection is normal again. What's strange is that this phenomenon only happens between my Macbook and the home network. I've also increased the lease time to almost unlimited but the lease still expires every half hour or so. – Fabian May 6 '15 at 19:48
