RV345 Randomly disconnecting from the internet

[azimirhotic]

I just implemented an RV345 router at my company and for some reason, every 3-4 minutes the internet drops for 20 seconds. I was running a continuous ping to 8.8.8.8 and google.com and you see the response timeouts when it drops. 

The router is connected to a bridged modem with a static public IP address. To make sure it's not the ISP I statically IPed my laptop to the public IP address and ran some tests.  I never dropped ones for the next 2 hours but as soon as I went back to the router I started dropping packets randomly. 

Wondering if someone would know what could be causing this issue.  the router is at the latest firmware.

what kind of bandwidth from ISP, what is the utilisation ?

what is firmware running for now?

I am getting 450 down and 60 up.... Utilization is minimal as I have my laptop plugged into the router only. As for the firmware version I would have to check tomorrow as I don't remember the number but I know it's the latest version for the RV 345 model because I upgraded it as soon as I unpacked it.

 - Also check the logs on the  RV345, better still - configure a syslog server, to keep watching and analyzing logs in a                                                                              more flexible manner.

Hello azimirhotic,

I have had a similar (the same?) issue with an RV345 where
[1] WAN1 was configured with a static IP address and connected
[2] WAN2 was left on DHCP (per default) and not connected.

With the above configuration, there were times when everyting worked smoothly and the, all of a sudden I would packets would be dropped in bulk. Or even more strangely observed behavior: drop one, reply ok, drop one, reply ok, ... and so forth.
Needless to say, an unworkable situation.

As soon as I configured a static IP address on my WAN2 interface (and kept it disconnected) the drops in my continuous ping disappeared. I recall leaving it running overnight and when checking next morning I had onbly missed 14 out of 43900 packets, due to connectivity loss by my iSP.

Perhaps this can be of help to you.
Michael.
