I installed openwrt to test for fun.. it worked fine and since then, I have only been able to manage/change my ISP details and change wifi passwords.
Rest everything is bounced off my head.
However I wish to upgrade my router software.
This is my existing router details:
|Model||TP-Link Archer C2600|
|Architecture||ARMv7 Processor rev 0 (v7l)|
|Firmware Version||OpenWrt 18.06.1 r7258-5eb055306f / LuCI openwrt-18.06 branch (git-18.228.31946-f64b152)|
|Local Time||Mon Jan 20 23:49:34 2020|
|Uptime||6h 12m 30s|
|Load Average||0.34, 0.25, 0.18|
Please guide me to write/correct software link and also guide on taking backup in case something fails.
