[Solved] Cannot ping my Arch linux pc from other devices

Question

My newly installed arch linux pc is connected to my home network via wifi. I can successfully connect to the Internet. Also, I can successfully ping other devices on my network. However, I am unable to connect to my Arch linux pc from any other device on the network. As I said, I cannot even ping it from these other devices.
Does anyone have an idea as to what would cause this?

I switched my Arch box to Dhcp. I thought the problem had resolved, but the issue has come back even with Dhcp enabled. I have isolated the problem to the wireless router. If I refresh Dhcp on the router, I can then ping my Arch box from other devices again. Is there anything I can do to the router to resolve this? Again, the wireless router is an Asus RT-N66U.
