Connection reset repeatedly, also can see downstairs neighbors devices despite having separate wifi networks

Title pretty much describes it. In any sort of download or long-term connection, many devices experience repeated connection resets. During problematic periods (which seem somewhat intermittent dependent on device), devices experience constant dropping of connections, and are dependent on app and websites to re-establish connections.

I am also able to see and manage all the devices on my downstairs neighbor’s network, which worries me. I suspect they may have the same power over my devices, which is frightening, not knowing my neighbors.

First. Is this a Comcast rented gateway device ? If so, check to see if the MoCA feature in it is enabled. If it is, and if you do not have a POE (Point Of Entry) MoCA filter installed on the coax line, yours and your neighbor's gateway devices will be able to connect with each other like one big network. Disable it if you aren't using it. If you are, install a POE MoCA filter to keep the signal in your premises and to keep the neighbor's signals out. Your neighbors should also have POE filters installed.

To disable MoCA on your device go to the gateway login http://10.0.0.1

Default login info is:
Username: admin (all lowercase)
Password: password

Once in you will find the drop-down on the left of the screen that is labeled “Connections”.

Click the drop down---> click MoCA---> right side of screen click “disable”---> save changes.

Bear in mind that we've seen many posts here that the MoCA feature gets turned back on with their overnight re-boots / updates for the device. Best policy is to be sure to use that POE filter ! Amazon has them: https://www.amazon.com/SNLP-1GCW-Filter-Eliminate-Multi-Room-Interference/dp/B07SLD9QPH
Or you can get one for free at your local Comcast / Xfinity store.

@EG This took forever to accomplish given my landlord situation, but I just want to say thank you! Installing POE filters on both of our cable/modem combos has gotten our network working flawlessly.

For anyone else with a similar problem, installing the POE filter on my device prevented my downstairs neighbor from controlling our devices, but the packets being sent from our devices still seemed to get picked up by the downstairs network. This meant that connection problems persisted until my downstairs neighbor installed a POE filter, just like you said. Thank you so much again!
