How do I fix a problem with a Mac using Wi-Fi networks to drop lines frequently?

My Mac is frequently dropped when using Wi-Fi networks, sometimes a few hours off, sometimes a few minutes. At first I thought it was OS X, and after a variety of optimizations and fixes, the problem remained. Frequent disconnection This problem occurs after the use of Tp-link router, before using D-link all normal, think it should be a router problem, but also a toss, toss the problem still exists. Finally, Google found a way to solve the problem.

The workaround is as follows

Open "Network" in preferences, if you have not changed before, you will see the "Location" column is "Automatic".

I don't know what the principle is, but it's this "automatic" location that causes my WiFi to drop frequently, so I'm going to add another "location". Select Edit location and add a custom location, the name is random, I use the name is "Home Office":

After adding the location, click "Advanced ..." in the lower right corner, then click "DHCP Renew" in the "TCP/IP" column, do not set the other, and finally apply our settings.

This will solve the problem of my disconnection.

If you still have the problem of disconnection, then in the router to change the wireless channel to 6 or 9, do not ask me why this change, I do not know, this is the result of my Google.
