Cisco RV082 - upgraded to firmware 4.2.3.07 - DNS is not working

So on the previous firmware, v4.2.2.08, the RV082 lost it's configuration for me to log in.  I couldn't even log in with the defaults.  Luckily, the router lasted for a few weeks without any other issues.  So I power cycled the router a few days ago and it reverted back to factory defaults!  I configured it for our network again and upgraded the firmware to v4.2.3.07 and everything seemed fine.  Now, DNS doesn't work.  When I set the DNS (issued by our IP), the client connections work fine for about 5 minutes, then DNS stops working.  If I manually set DNS on the client adapters, it works.  I used the same DNS that is configured in the router.  

Anyone experience similar issues?  I don't know about reverting back to a previous firmware because what other issues will I find?  I don't think there is anyway for me to not set DNS correctly?

***Update: I think I have

***Update: I think I have resolved the issue!  It looks like there are two sections where you can set the DNS.  The first one is under Setup | Network | WAN1 - Configuration.  This is where I set the DNS because they are required.  The other section is under Setup | DHCP | DHCP Setup | DNS - I set the dropdown to "Use DNS Below" and set my DNS in the boxes.  This is not a section I configured with the previous firmware.

I feel like the firmware upgrade now looks at the DHCP DNS section to determine how to route the clients.  Why this isn't what the WAN1 section takes care of.....who knows!
