Hi All i have this wierd issue.. I just tried a couple of time to flash my Linksys Cisco EA 6700 and everything was perfect.. When it was done i cleared the NVRam and router rebooted. Everything was perfect. I started configure my router WIFI and works perfect.. After a reboot the 2.4GHz WiFi disapears and the 5GHz is more limited in the settings. Plus it reset the WIFI config back to standard. I searched and search and found this guide: https://blog.adriel.co.nz/2017/09/05/advancedtomato-on-the-linksys-ea6700/amp/ and i tried with Fresh Tomato and Advanced Tomato with same result.. After i have tried these things i tried to reflash again, claer NVRam and when it got back then i rebooted the router again and allready there the WIFI disapears. Are someone farmiliur with this issue, when i see on google this is a known issue from advanced tomato. Update: i tested with DD-WRT Firmware: DD-WRT v24-sp2 (02/19/14) std and it works perfectly.
