Right now my hardware consist to Raspberry Pi OpenWRT trunking down port 8...Port 1 is is connect to the cable modem.. everything works great...I am trying to create a vlan ID 2 on port 7.. for guest...

Thanks for reply. I found out one of my device is bad.. so nothing is wrong with my cpe 510...

My CPE 510 keep disconnecting and I would have to reboot once a day. Does anyone here uses Openwrt?
