Ifconfig show 300 errors is this bad?

My router has been up for 1 hour. eth1 is showing the port is up and transmitting, but how is it transmitting if the only Ethernet port that has a cable plugged in is the wan port.

The eth1 port is not any of the wired ports. eth1 is the 2.4Ghz wireless radio. Eth2 is the 5Ghz radio and eth0 is the wan. The errors don't seem like a lot and if you want you can clear the counters to see if the problem continues. Errors can be generated for a number of reasons.

Also, I don't know if you are concerned with this but there is quite a bit of information in your post that you would normally want to keep private.

Public IP Address
Local Networks
tunnel interfaces
mac information
router model
router os

I just wanted to let you know to help you better protect your network. Hope this helps.

Having a few errors on a wireless interface is normal. The amount will vary based on how much traffic you have on that interface, and the signal quality between the clients and the router. They simply denote retransmitted packets in general.
