wifi connection to specific devices is flakey. keeps dropping at random.

@XfinityJay​ I appreciate your response. As it is... I've spent a fair amount of my holiday weekend dorking around with this. The fact is... when I put the XB7 in bridged mode and use my Google Nest Wifi gear, all my problems go away. The tech support for these little devices I referred to recommended I turn off "band steering". So... I took the XB7 back out of bridged mode to try it. Of course this involved splitting my network into two different SSIDs. This was a major hassle. And... it didn't solve the problem. Thinking it might be a firewall issue, I then completely turned off the advanced security features. That also did not help. So... I once again put the XB7 into bridged mode and put my Google Nest Wifi gear back into place.

What I don't understand is... the XB7 was reporting speeds exceeding 1200Mbps. But my Google Nest Wifi router, connected directly to it... only reports speeds in the neighborhood of the 880Mbps.

You mention "signal levels". The devices I have that are being troublesome are within 18 inches of the XB7. I'm going to hazard a guess that signal strength is not the problem. But the real issue is... I'm so weary of messing with this for now, I'm not willing to take the XB7 out of bridged mode unless you have some sort of suggestion (other than pointing fingers at signal strength).

Not sure how you measure signal strength. But the devices I have that are not getting along with the XB7 report in the neighborhood of -19 dBm.

You can continue to use your modem in bridge mode. The Google devices may have a limitation on them that would keep them around the speed you are seeing, you would need to check that out with Google. It appears your services are working correctly and you have service into the home. 

I realize I can use the XB7 in bridge mode. But I'd much rather get the problem worked out. Using bridge mode doesn't fix the problem, it works around it. I went with the XB7 gateway specifically so I could get the speeds I'm paying for. If I can't do that, then I may as well downgrade back to using my own modem and a lower speed plan.

We would still need you to send us a Private Message if you would like us to look into this further. We'll need your full name and address to see if there is anything concerning with your signal levels.So far the issues you've described don't appear to be pointing to the connection we are providing you directly which is why the recommendation of consulting Google on their devices was given. We will do our best to troubleshoot considering there are third-party devices within your home network but because we don't fully support third-party devices, we may need you to consult with them if we don't find a singular indicator that would be a reason why this is happening.

@XfinityBenjaminM​ You are correct. The problem I'm having is not with the connection, it is with the equipment. I am going to resort to leaving the XB7 in bridged mode. I have purchased a router that has a 2.5Gbps WAN port. In theory... this should connect up to the XB7 and give me full speed, correct? One of the XB7 LAN ports is 2.5Gbps if I'm not mistaken.
