I got some problems with my WiFi setup.
In my setup I use a Macbook Pro and a TP-Link WR1043ND v1 (OpenWRT). WiFi Channel is set to 6 (already tried other channels and 20/40Mhz width)
If I ping my macbook or my router from my macbook, the ping is really high.

I already tried another router (Linksys E2000) but its exactly the same.
Ping is a tool to test for network connectivity, and you shouldn't put too much stock in the reported latency since it doesn't reflect real TCP or UDP performance. Another problem is that this is Wi-Fi, and you are at the mercy of whatever wireless interference you may have, including from other devices on your wireless network since it is a half-duplex medium. – Ron Maupin – 2016-02-11T19:08:45.170
2Such spikes might be caused because of using a rather busy wifi channel. Try to scan your wifi channels with inSSider to find the freest channel and set up your wifi router to use it. This might significantly increase your connectivity. – Net Runner – 2016-02-11T19:40:22.210
