First time for me trying to install OpenWRT on my Netgear R6220. So far I have followed the steps at " Installation through telnet" (https://openwrt.org/toh/netgear/netgear_r6220). I´ve made It to "telnet IP-address and login with “root” (default: admin - password)", i used Putty. But next step I dont know what to do, If i type in "/mnt/shares" I get the message "Permission denied". What´s wrong with that command? Should I do something else? Thankful for help.
Pressing the third (middle) button on the mouse pastes.
Is there a console....in a web GUI...?
I'm not sure you understand that contradiction. There have been talks of an app that exposes the console...but you already have access via PuTTY, and I'm not sure that app is in the software repository.
