Modify your current device and replace it with Linux Embedded Development Environment (LEDE) software: an operating system based on Linux, formerly known as OpenWRT. This is a complete substitute for software that is commercially available for this type of devices. It has a very wide list of supported wireless routers. People decide on LEDE, because they are convinced that it works better than the one provided by the manufacturer. Actually, many factors indicate that it is more stable, offers much more opportunities, is definitely more secure and has better technical support. Due to the fact that it convinced us, we can recommend it with a calm conscience. So write to us about your router or replace it with the one offered by us, which has desired system configuration and a really nice UART header which make it best.
