I constantly lose my Internet connection. After analyzing the problem I found that my router, TL-WR741ND [TP-Link], changes its MAC address by switching through the WLAN's, LAN's and WAN's MAC addresses.
If I clone the MAC address of the router's WAN to the one I want, it doesn't change automatically. Probably a bug.
I am using DD-WRT v24-sp2 so I should be able to change something in the OS.
How do I set a MAC address to the device and make sure it doesn't change its MAC on the WAN port?
