Preventing unwanted devices on my xfi

Preventing unwanted devices on my xfi

I have been receiving texts on my phone regarding "a new device has connected to your internet" and now, I have a long list of devices on PAUSE. I do not want my internet for Public Use. I chose this somewhere but these unwanted devices keep showing up. My family/friends are all labeled to use my internet and they are the only devices I want to keep tabs on. I tried calling Xfinity but it is impossible to contact another human on that side. Any help/advice is appreciated, thank you for reading. Have a nice day.

Re: Preventing unwanted devices on my xfi

I get those messages when a device i own connects through wifi but I have been able to identify them; some are my TV's some are my family's devices, android and apple.  My printer shows up.  But they are all ones I allow except for "sneaky" wifi devices like home appliances even my weight scale.  As long as you have only given your SSID passwords to your allowed users, you might not have any issue.

 

Give us some examples of device names you are suspicious of.

Hi Robert! These devices are Apple, loads of numbers and other peoples phones......these are not appliances in my home. All my devices have been entered and are labeled on the XFINITY acct. We do not have 25 devices that have not been used.

Re: Preventing unwanted devices on my xfi

I have had this same issue! I noticed my WiFi really slow so I looked into it finding several new unknown devices. Changed passwords and names only to find twice as many the next day. I have also called Comcast but was disconnected several times. After many changes, pausing everyone, and no longer broadcasting my network I have only had one new unknown device. I am afraid to use my WiFi and fear I can no longer trust some of my devises .

Just how are these people connecting their cellphones without our password. Funny thing is they are never connected more than a few minutes or seconds.

Has anyone found a fix? My public WiFi signal has already been turned off for a few months but I’m still having this issue...

Re: Preventing unwanted devices on my xfi

xFi will only show devices that have successfully authenticated and joined your private network. To confirm that the device is fully authenticated (correct WiFi name and password were entered), you can check the Device Details for an IP Address. A valid IP Address means the device connected to your network. 

The Device Details also provide some data points that can help identify the device - brand, operating system, model, etc. Most of this data can be determined after a few short minutes of the device being active on your network, and can help with device identification.

 

If you have concerns on a specific device, I would recommend forgetting the device in xFi and changing your WiFi password and then seeing if the device reappears in xFi. This may help pinpoint which device it is.

Re: Preventing unwanted devices on my xfi

I have public wifi turned off and I've changed my password. Immediately after changing my password, the same random devices and some new ones keep connecting to my wifi.

I have several devices that do not need a password; for instance, my Chromecast dongle shows up in xFi Devices.  I have 5 X1 STB's and they are connected to xFi.  Also, my router and my modem are in xFi.

Could you give us more information about your devices, like device name and MAC address?

Re: Preventing unwanted devices on my xfi

I had the same issue...received a "new" different modem...went to my xfi app and there were 55 do devices showing up. These were ALL coming through the "new" modem I had just received. The tech I spoke with On the phone had to manually remove them.

Re: Preventing unwanted devices on my xfi

That's real strange. The first time I set up my Chromecasts and I have both Chromecast and multipe Chromecast Audio I had to enter in my xfi router's password to connect them. You might want to rethink that or explain how your router does not require only your Chromecast a password to connect. 

BTW I and most folks here have named all their devices and know what devices they have in their home. The unwanted devices mostly show up for a short period less than 5 minutes and are gone. Changing password does not keep them from connecting. This really needs to be explaines by someone from xfinity but they refuse to help and just keep saying issue is solved or going to be solved but never is.

Re: Preventing unwanted devices on my xfi

Have changed password several times. New devices show up again. They had no way of knowing password. Again most devices only connect for less than 5 minutes. I know all my devices and have them named.
