MR60 Ethernet keeps disconnecting at random times

[JacksonBroome]

Every so often while I am using the wifi extender, my Ethernet and Internet will keep disconnecting at random times

1. what modem/gateway is the router connected to? 

2. what extender do you have? 

3. Why are you using an extender versus the MS60 satellite?

[JacksonBroome]

I have it connected to a Nighthawk pro gaming XR700, I have the nighthawk MR60 extender, I've never heard of the satellite version before so I believe I bought the MR60 when it came out before the MS60

The MR60 isn't an extender. Its a router. 

And the MS60 isn't an extender either. Its a satellite for the MR60. 

If you have the MR60 connected to the XR700, the MR60 should be in access point mode. 
you should also have it set with a separate ssid and different channels from the main router or they'll interfere with each other. 

Not sure who told you the MR60 was an extender
