Orbi iMac issues

Hi there

I wonder if someone can help. FURRYe38 was incredibly helpful before when I had backhaul issues - all sorted now.

My iMac is losing wifi connection intermittently. All other devices are OK.

I've attached some screengrabs from Orbilogin.net.

• The two satellites look good
• However, the iMac (highlighted in the red box) says it's connected to the 'Orbi Satellite', not a specific named satellite ('Breakfast Room' or 'Upstairs') ... this seems weird
• Also, when selecting the device (I checked this is the correct device by finding the IP address in wireless settings), it shows as a Macbook Pro 13"  and a Laptop when it is in fact an iMac. 

Could the above be part of the problem?

Any advice would be great!

Thanks

Rob
