what is a problem ? and how do I solve it ?

[balaji.bandi]

what is the firmware running, try reboot the device and see if that fixes ?

[YOUNGDONGLEE8988]

I use firmware version is 1.0.03.21 on RV345.

It's a supermarket, so the reboot should be done later.

[nagrajk1969]

- whats the connection type on each of the wan1/wan2 interfaces? (is it dhcp/pppoe-wan/static-ip?????)

- Is the wan connection via a fiber-modem (with vlan-id..... something like that)

- Try with disabling "Network service detection" set to default-gateway in the Wan/Multiwan gui page for each of the wan1/wan2 interfaces, do a apply, and then apply-save and reboot once
