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 s...

Hi joe_schemo,
Kindly try to uncheck then re-check "Enable Stealth Mode" as shown below:
About the logs, it would be best to open an online case with NETGEAR Support then attach the logs to it as well as indicate your concern/s. The online case will be escalated to the engineering team for the logs to be analyzed.

I have A FVS318N running latest firmware. Recently changes over from DSL to Cable with 190 MBit / 30 Mbit connection bandwidth. I'm able to attain these speeds without the Netgear firewall in place all the time.
I created my configuration for the Cable setup from scratch and am able to get the speeds advertised with the Netgear FVS318N in place. however, after a certain amount of time (I have been unable to determine how long) the speeds achieved throu the FVS318N drop to below 30 Mbit down and up.
The only solution to regain the 190Mbit down speed is to reboot the firewall
The firewall log contains several indicators that there is a memory leak in the current firmware:4.3.3-6

Hi rlcarper,
Welcome to the community!
Does it mean that the problem started when you have switched from DSL connection to cable internet connection?
Have you tried to uncheck Block TCP/UDP Flood as shown below and check if same problem occurs?

The DSL conenction was only 8 Meg down and 1 Meg up. SO I never reached the limitations of the unit. A couple of months ago I posted this problem on this forum, under another username (noibla) seems taht the profiles have been removed on the forum.
I have enable Block TCP flood, with 100 packets per second ( maximum setting)
I have enabled Block UDP flood, with 100 ( minimum is 25)
Stealth mode is enabled.
disabling TCP flood does regain some performance, but only back to 140 Meg instead of the 190 Meg available.
What are the recommende security settings for TCP and UDP flood for this connection speed?
Is there any better product from Netgear available that can achieve the 250 Mbps or higher through put with security enabled?

Hi rlcarper,
Have you already tried to reset the FVS318N back to factory default settings then reconfigure it from scratch and check if same problem occurs?
If ever you want to consider other NETGEAR VPN Firewall, you may want to check the FVS336Gv3. For more information about FVS336Gv3, check these links below:

Hi Danea,
As from the previous community thread I had already completely rebuilt the configuraition from a factory default starting point to the current configuration. In the previous case I found out that enabling traffic manager impacts the performance of the device. Now it seems that overtime, the device's performance drops. Maybe time for an upgrade on the memory and the processor?
The alternative firewalls lack wireless connectivity, and are not really an option
- rlcarperMay 21, 2016Tutor
After disabling the Attack checks for TCP, without reboots, the performance drops to 5 Mbps down and below 1 Mbps upload.
Time for a new firmware?
- DaneAMay 22, 2016NETGEAR Employee Retired
Hi rlcarper,
I do not have any news if NETGEAR will release a new firmware version for the FVS318N. Also, we cannot conclude yet if this is a bug on the firmware.
Here is my suggestion. Access the Packet Capture Tool on the web-GUI of the FVS318N. Go to Monitoring > Diagnostics. Then on the Diagnostics page, see the Router Options. Click the Packet Trace button then choose WAN on the Select Network options. Check pages 379 on the FVS318N reference manual here.
Once you have started the packet capture, begin to surf the Internet until the speed drops down from 190Mbps to 30Mbps. Stop the packet capture only when the problem occurs. Then, download the packet capture on your PC. For the packet capture to be analyzed, I suggest you to open an online case with NETGEAR Support then let them know about your concern. Attach the packet capture on the online case you have opened for it to be analyzed by the engineering team.

DaneA

I believe that the packet capture would be so big that the memory of the router would be already full before finishing the capture.
how about the analysis of log entries? They clearly indicate a memory leak...
- DaneAMay 25, 2016NETGEAR Employee Retired
Hi rlcarper,
It would be best to at least try using the Packet Capture Tool of the FVS318N.
About the logs, you may attach it on the online case that you will open with NETGEAR Support for it to be analyzed.

Hello,
The issues is not resolved. When I enabled teh PCAP to run, the resulting PCAP did not contain all of the generated traffic. So the PCAP tool is of little/ no use here.

Hi rlcarper,
Firmware v4.3.3-8 has just been released for FVS318N. For the meantime, kindly try to update the firmware of your FVS318N to v4.3.3-8. Be sure to reset the FVS318N back to factory default settings after upgrading the firmware then reconfigure it from scratch. Observe if same problem occurs.

2M: This is what the culprit was eventually. If you enable the traffic manager, the unit will warn for performance drops. I removed this and was able to get my 190/30 speeds, but now after a while, the speeds drop, hence my comment on memory leaks...

Hi noibla,
I am sorry to know about that. :( If only its possible for you to open an online case with NETGEAR Support in order to forward the logs to the engineering team.

I'm very disappointed in the support from Netgear. I have stripped down the router configuration so that minimal logging is enabled and still the loggin seems to be garbled and overrunning. With the Latest software release form august 2016 nothing has changed.
I was never able to create a case with techniocal support due to the impossible menus to input the serial number of the unit which I really have, but seems to be linked to another account (???)
I have trusteed Netgear for many many years (20+) as a reliable networking and firewall product company and the products suited the existing needs, but the Internet connection moved on and now the products seem to be capable of providing the performance, thy don't after 1 day or even sooner.
I reboot the router once in a while and then I'm able to get the speed that I have with my ISP (190 Mbps down and 30 Mbps up). but after a while this drops back to 56/30.
Very disappointed with a product that has a datasheet that claims 250 Mbps throughput. That is unacceptable for business grade products such as the FVS318N
Get this fixed!

It seems that you have opened online case # 27489789. I believe that the NETGEAR Support expert assigned on your case has already responded to you and is asking for the serial number of your FVS318N as well for it to be registered. Kindly reply into it and keep us posted.

Hi All,
The support case had led to the unit being replaced but something else happened too. 2 new firmware releases took place. 4.3.4.1 and 4.3.4.2. The 4.3.4.1 release note have the following comments:
Bug Fixes:
- Fixed the issue where the logs are not displayed properly in the GUI and on Syslog server.
- Fixed the issue where the firewall logs contain incomplete logs messages.
The unit was replaced under RMA afer good response from the Netgear team. I returned my old unit and the new unit came in a box where the specs still referred to the old datasheet (95 Mbps WAN-LAN).
Both units (witn 4.3.4.1 software ran fine with the 190 Mbps consistent download. I also further looked into differences in the hardware platform used (Cavium CNS3411 Network processor). Both units were the same.
To summarise: it was likely a memory leak issue in the prior firmware in relation to the log messages prior to firmware 4.3.4.1

Hi rlcarper,
Thanks for the update.
I'm glad that both units you have are now running fine. It seems that the new firmware has solved the problem.
Since your concern has been resolved, I encourage you to mark the appropriate reply as the “Accepted Solution” so others can be confident in benefiting from the solution. The NETGEAR Community looks forward to hearing from you and being a helpful resource in the future!

I guess we celebrated too soon. Performance dropped back to 50/30 Down/Up.
Case needs to be reopened
- DaneANov 28, 2016NETGEAR Employee Retired
Hi noibla,
Since there is a problem with the replacement unit, you may go ahead and contact again NETGEAR Support. Let them know about the previous case number or the RMA number given to you as reference.

We're back to sqare one. However, Netgear support is still trying to find options to address the problem.
Currently the daily reboot results in a temporarily speed to 190/30, but within 7 hours, the performance is below 50 Mbps down again
