Recently I’ve been fiddling around with the nodemcu/esp8266 with different firmware’s and such and figured out that i could set it up as a WiFi repeater/range extender!
Below, i’ll provide the link to the flash-able firmware which i used the “nodemcu flasher 64bit” program to flash it with, the github recommends to use the esp8266 download tool v3.4.4 (both works).
Just follow the instructions on the following resources i provided, and if you have any issues you can contact be from the links to my social media below or comment on this post and i’ll help you with any queries.
