I recently ran into a problem where I was not able to ping, SSH, or otherwise connect to a computer on my home network. My router is using DD-WRT. Both machines were wired in.
In the DD-WRT admin page navigate to
Enter these commands (both lines at once) and click
swconfig dev eth1 set enable_vlan 1 swconfig dev eth1 set apply
This should fix the problem immediately.
Occasionally, I encounter an error when running these commands. I do not understand why.
To troubleshoot this. I will do the following (not necessarily in this order, and often, multiple times).
- Run the commands one at a time.
- Wait a while.
- Run both commands at the same time again.
Eventually, the commands run successfully.
