Should I disable "Enable VLAN functionality" option?

I dont need the vlan functionality since it is a household router (WRT3200ACM). Does disabling it reduces the overhead if I dont need any vlan function?

So my question is what happens when I check "Enable VLAN functionality"?

This device has two eth interfaces, one connected to the WAN port, and the other one connected to the internal switch that gives access to all the LAN ports.

So... yes, you can reconfigure your network and avoid using VLANs; however, I doubt that you are going to improve the performance at all.


Thanks, I disabled the Vlan, how do I configure and avoid using VLAN? do I delete the second VLAN?

Do not disable it. VLANs must exist inside the switch to keep the WAN and LAN networks separate. If you uncheck the box all 7 ports (5 external and two CPU) will be fully linked to each other like an unmanaged switch.

The switch is specialized hardware. It will act at the full speed of the Ethernet ports even with VLANs operational.

VLANs don't exist outside the switch if the ports are 'untagged'. You could make both CPU ports untagged but this would have really nil increase in performance and make it difficult to add more VLANs if you ever wanted to.

Just configure WAN on eth0 and LAN on eth1.

I enabled it again. Thanks for the info.
