RBR40 Router dropping Arris TM822A, I think

Hi,

Thanks for helping!

I think the most important clue may be that we cannot login to our router when we lose WiFi. It doesn't show up as an availble network from any of our devices. 

>Tray swapping out the LAN cable between the modem and router.

I swapped out the cable with new some time ago.

>Disable IPv6 on the Orbi router.

It's been disabled all along.

>When you loose connection, can you still access the routers web page?

No. The router disappears from an available WiFi device so I can't even get onto it.

>Do both wired and wireless devices access the routers web page when this happens?

Presently I only have wireless devices on the network.

>Might have your ISP check your service signal from there side to the modem. Have them check there logs for any disconnections during >these times frames. You might check into a newer model modem. Preferably a stand alone modem. No built in router.

The symptoms of our current problems don't quite fit with dropping the ISP. We fought a long ISP battle over the course of a number of years with our modem dropping the ISP. We could always login to our router but we did not have an internet connection and the LEDs on the modem showed that a connection was dropped. We are experiencing neither of these circumstances presently. In the end, after numerous visits from our ISP's techs, we ended up with a new modem, they boosted our signal level from down the street and finally they figured out the builders did a really **bleep**ty job terminating coax cables.

I don't have a problem replacing the modem and maybe it's worth a shot in the dark? However, it doesn't seem like replacing the modem quite fits the problems we are experiencing (coming from a guy with limited knowledge).

Any wifi neighbors near by? If so, how many?

We have around 10 WiFi neighbors.
