Got RV320 for 6 weekes.
Configured for replace a RV042 running for years with 18 VPN tunels to remote offices.
RV320 worked for 16 hours (12 night hours, no activity, 4 working hours) before first failure (no ping response an LAN side, no VPN tunnel up, interface on WAN side loading one screen in 2-3 minutes. Reboot and after 3 hours had second failure.
RV042 returned to service, RV320 got back in box, waiting for some time to look at.
Tested also mobile network with Huawei 3131 usb modem and had no trouble. Got connection etc. Have not tested VPN over mobile network.
I bought mine a week ago and had nothing but problems. I noticed my ISP speed was much slower so I sent it back and went back to my old RV 082 which has been fine for me. I am sorry I had so many issues with this product I was looking forward to upgrading my old router.
I have made new discussion about RV320. If you have had similar problems, plesase
