FVS318N requires periodic reboot
I reviwed the community article titled FVS318N router keeps dropping network connectivity, which was closed due to inactivity. I'm having the same problem where the router runs for about a week or so then stops forwarding traffic. I can ping the router but can't ping through it. I cannot connect to the Web Management Interface. I have not tried to telnet into the router yet. Is anyone else having this problem?
I have not downgraded firmware because I've seen ample evidence that won't fix the problem due to posts noted in the first paragraph.
It sounds like some sort of memory leak but there is no way that I've found to list available memory from the Command line interface or the Web Interface. Does anyone know how to list available system memory? Having that capability would allow me to monitor memory over the week to see if the available system memory gets smaller and smaller.

Hello WMC,
Welcome to the community!
I suggest opening a support case for this one so it can be isolated properly. Were you able to download the logs and see anything that is out of the usual? I have seen a case logged similar to the issue you are having but it is better to get the techs involved so that we know if it is the same issue.
Looking forward to your response.
Thanks,
You ever get this sorted? I just upgraded the FW this weekend and now I have the same problem as you.
Hello joe_schmo,
What firmware version are you using on your FVS318N? I cannot confirm that there is a memory leak issue since I don't see one reported on our logged issues. Still waiting for @VMC to open a support case for this one. Can you provide me some details about your network and did the issue started right after updating?
Looking forward to your response.
Thanks,
I was watching this thread with keen interest as I never saw higher than 50Mbps on all 3 of my FVS318Ns and was hoping that someone found a solution.
Here's the solution that worked for me, and I tested it in a lab scenario for 48 hours passing over 100GB in data from the lan to wan, and then letting it sit for a day, and it still worked with speeds of 179-180Mbits from wan to lan (fastest our Internet go). Upgrade to firmware 4.3.4-1. This upgrade as so far solved any speed issues. I plan to roll it out to all our FVS318Ns. I don't know what else might be broken though, so watch for any other issues on other features you may be using such as port forwarding, dhcp, vlans, etc. Good luck!
Hi Samird,
I am using 3 SSID's on my Wifi in this router and several VLANs. have inbound port forwarding and outbound rules (default rule = deny)
used to have VPN as well and trafic meter enabled, buit VPN's no longer needed and trafficmeter aparantly reduces performance to 30/30.
What setup did you use to test 48 hours?
Running
Firmware Version: 4.3.4-2 now
I left it in bone stock setup besides changing the subnet of the lan to keep it from conflicting with an existing lan. I ran the dslreports speed tests as they consistantly would max out our connection properly.
I tested a few times after setup.
Then because this was a local lab setup, I ran an iperf to a system on the 'wan' for 24hrs reporting once every minute (iperf -c 192.168.1.11 -t86400 -i60). Once it passed that test, I again ran a speedtest and then called it good.
The next test was putting it into production where the Internet is a 60/5 connection. Normally it would be right at the 60 mark. It tested 65/5.
I would try testing with all the wifi disabled. The wifi on the 318N is terrible. I'm about to get a 802.11ac AP as 802.11ac is faster than the N anyways.
As far as the port forwards, I didn't try any.
Hope this helps.
