I'm a very power user of OpenWRT and also a light developer of it. I
happen to have one of the Archer C7 v2 units myself. I agree there are
definitely some bugs there but the switch config is not something we
can do much about I don't think. I agree it's quite different than
other devices but that is because of the way the hardware is built and
not because of OpenWRT. Once you actually figure out the switch
configuration it's pretty flexible, just different than what you would
expect. Because it's different than many devices the LuCI interface
for configuring it is misleading and confusing. I find it less
confusing to work with it in the /etc/config/network text file
configuration. When I get some time I hope to do a better job of
documenting it. You can definitely do VLANs though, in fact two VLANs
are part of the default OpenWRT config on this device.

Basically, it is a seven port switch. Each of the five physical
Ethernet ports (WAN, LAN1, LAN2, LAN3, LAN4) are represented and it
has TWO CPU ports. A table showing the relationship of the switch
ports to the physical and CPU ports is on the wiki at

The default configuration is to use VLAN1 to carry the LAN traffic
(connecting eth1 with LAN1, LAN2, LAN3, and LAN4) and VLAN2 to carry
the WAN traffic (connecting eth0 with WAN). You can add extra VLANs if
you so desire and change eth1 (switch port 0) to a tagged port. In
this way it will operate just like any other OpenWRT controlled
switch. The key difference is that you must always reserve one VLAN
for connecting the WAN port (switch port 1) to the eth0 port (switch
port 6).

Hope this helps clarify!
