   - <color red>In failsafe mode, the router will not respond to network traffic from outside the 192.168.1.0/24 subnet, so you cannot telnet or ping it unless the source is also in this range of IP addresses. You may need to temporarily set a suitable IP on the device used and/or ensure that any routing and firewalls will allow packets if accessed across a network.</color>    - <color red>In failsafe mode, the router will not respond to network traffic from outside the 192.168.1.0/24 subnet, so you cannot telnet or ping it unless the source is also in this range of IP addresses.

   - If the router does not boot in safe mode despite clicking the button, it may be a timing problem, missing the brief window when OpenWrt is looking for a button press. If so, immediately after turning the router on, rapidly click and keep clicking the button on the router for about 60 seconds to try to not miss the safe mode boot window.   - If the router does not boot in safe mode despite clicking the button, it may be a timing problem, missing the brief window when OpenWrt is looking for a button press.
