FVS318Gv2 Connectivity Issues with Firmware 4.3.3-8

Tldr:

• Power went out again...

• FVS318Gv2 wont remain connected to the internet and locks up after 2-15 minutes
• Changed MTU from 1500 to 1492
• Called ISP and had them reset my profile (they say it’s reprovisioning the modem)
• FVS336 works perfectly, but WAN throughput limited to 30mbps (I have 60mbps)
• I currently have the FVS336 connected as this is the only way I can have stable internet.

I just got off the phone with netgear.  The call was well over an hour and the person on the phone was extremely polite.  I still have the same problem, the FVS318Gv2 will not remain connected to the internet) It’s HOT here in Texas and I guess we are beginning to have rolling blackouts.  The power went out today and I am still not able to get internet with the FVS318Gv2 for more than a few minutes before it locks up.

I have plugged/rebooted/unplugged the modem and the router in every configuration possible and the internet will work for about 5-15 minutes then the internet light will go out on the FVS318Gv2 and the router will locktup/hang and the only way to be able to access the web GUI is by unplugging/replugging in the router.

While on the phone it was suggested that I call my ISP and have them reset my profile.  I kept trying to explain that when I reboot my FVS318Gv2 and it stays connected for more then 20-30 minutes, everything works perfectly.  And that I have never had to have my ISP reset anything.

I was finding it hard to believe that my ISP (I guess while refusing the mac address of the router) could completely lock the router up… Then I remember this from several years ago.  I HAD A FVS124G AND WINDOWS LIVE MESSENGER WOULD LOCK IT UP!!!  That’s right, everything would work, but the second I opened up Windows Live Messenger, the router would completely lock up.

This problem is different, because the internet goes down sometime after a couple minutes to 15-20 minutes.  If it stays up longer than that, it will work GREAT! I can’t recreate the issue to make it go down, it just locks up randomly sometime between turning on and 20 minutes.  I also can’t recreate any situation to keep the internet connection.  At least with the FVS124G the connection/router would stay up until I opened up and logged into Windows Live Messenger so I knew what the issue was.  Oh and the router has lifetime hardware, but not lifetime software and it was never replaced because the firmware would never be updated since it was EOL.

I kept telling the person from Netgear (I told a different person last week) that I can plug in my old FVS336G and everything would work great, no lockups and no reboots.  They said, then it’s obviously an issue with the ISP, because they still have the old info and that I need my ISP to reset my profile.  Did I mention that I had my ISP reset my profile (they say it’s reprovisioning my modem) last week with the FVS318Gv2 connected?  I called my ISP after my internet was stable and they reprovisioned my modem and it worked until the power went out this week.  It was also after changing the MTU to 1492, so I don’t know what worked or if this was the magic 1% of the time the FVS318Gv2 remains connected to the internet.

But here we are.  It’s been 9 hours and I still cannot get my FVS318Gv2 to remain connected to the internet.  So far I have changed the MTU to 1492, I called my ISP and had them reset my profile (reprovision my modem is what they call it) and it still doesn’t work.

For grins I thought that I would spoof my computer’s MAC address on my router. I did that un/replugged in everything and again, it worked for a few minutes then locked up.  I plugged in my FVS336Gv2 and spoofed this computers MAC address (I don’t know if that works or what, but I have the same settings on both routers now) and it works and I’m able to post, I just don’t see WAN throughput over 30mbps.

Any help would greatly be appreciated?
