mi424wr rev F, every 2 hours WAN dhcp renew drops connection for a few seconds

I've been having issues where my pandora or streaming web video would lose connection- also pidgin for AOL,yahoo,gtalk would disconnect.  Clicking reconnect for the music, video, or message client would work.

I didn't find out why until I started writing down the timing, like right now it happened.  

Here's the log as of 1:09 am EST:

From the security log I find at around the same time NAT errors, due to losing the WAN ip for that short dhcp renew period:

I have a 3+ year old mi424wr rev F with ethernet WAN on 50/50.  Speeds are great. 

Every time the WAN dhcp renews its lease of 2 hours, it temporarily drops the connection!

I have tried many different settings in the router, to no avail.  I have also rebooted the ONT and router.

It doesn't happen if I use my linksys or netgear routers, (but they aren't fast enough to handle qos).

So, I contacted support via chat and they ran tests for both the ONT and router and see no issue with the line.

So they called me and connected me to billing to see how to get this old router replaced but we got disconnected.

Honestly, I don't need any more speed- so I don't feel like to pay extra for a router.   I just don't want my connection to drop/reconnect every 2 hours which can be annoying during a game!

Does anyone know of a fix, or is it something typical of the mi424wr rev F?

I haven't experienced it in the past, but I do see that they updated it recently.  Maybe the update is the problem, but when I tried to reset and roll back versions it would just get automatically updated by verizon push update!

Thanks in Advance for any help.
