I noticed that on my workstation (Windows 7, connected through ethernet cable) I ping between 100-500ms to my Android phone which is also, of course, connected to the same WiFi through wireless.
Strange thing is if I try to ping my workstation from my phone the ping is normal (13-15ms)
This happens as well to other phones (namely iPhones) connected to the same router but doesn't happen to laptops connected always through wireless.
Ping between other devices connected to my router through ethernet cable all ping each other under 1ms.
What could possibly be the cause?
I even tried to boot up a Linux live cd and try to ping my phone and see if it was Windows fault or something but the high ping is still there.
I tried to use another router as well but high ping remains.
