XR500 drops internet

I installed the firmware that you provided and it seemed to address the wireless portion of the problem but the ethernet connections still malfunction. To sum up the issue again, everyday the connections would still be there but without internet access. When this would occur, I would still be connected but unable to access the router menus until a reset had been completed. After installing the firmware that you provided, the issue doesn't happen over wifi and I'm also able to reach the router menu through those wireless connections. It would appear that my wired devices are showing a failing static ip although nothing is static. It also shows my ip address on these wired devices as random ip addressess and not those that were assigned through DHCP. This problem only seems to occur the next day and it will last until the router has been reset. I wanna get this fixed in the next few days before my return window expires and I'm stuck with a $300 brick.
