Rogue devices showing up on windows 8 network in file exporer.

I know this is an old thread but having experienced the same with Window 10 latest, greatest & licenced.

I have noticed over the past year many devices pop up in my network, phone, laptops, tablets etc. and had the same concerns - I even upgraded my router to the UK BT Smarthub6 with increased security protection... it kept happening.

However, as was explained by an earlier post it seems that it's only devices which automatically do the hand shake thing and as long as it's not been assigned an IP address and nothing more.

I put the test by taking all my wireless devices off the network, confirmed that they were not connected and either only on cellular or non local network, seconds later my devices appeared in the list in the network, confirmed they weren't even connected but had tried the handshake when scanning for wireless network, so seems my worries are at ease now :-)

Good tips, except these two:

(b) Reduce the AP WIFI power level to 1 (one). Make sure all your devices can connect and work correctly. If...

I like my phone to connect as soon as I'm entering the building. Maximum power!!!

Power level 1 doesn't even reach the bathroom...

...Enter the MACs of the *wired* NICs into the "Not Allowed on WIFI" list.

Specifically blacklisting when blacklist/all is the policy? Pointless.

Filtering is already on and is disallowing ALL MAC addresses except the ones whitelisted. Don't protect yourself needlessly from yourself...

This is an old thread but ...

Some basic tips to protect your WIFI and AP.

(a)  Make sure your WIFI AP has a good password to protect settings.

(b) Reduce the AP WIFI power level to 1 (one). Make sure all your devices can connect and work correctly. If needed increase power in increments of 1. Test your devices at each step. Stop when they all work. Don't go higher than needed.

(c) Change your AP WIFI SSID so it doesn't contain any useful information. No family names, addresses, apt numbers. Don't give away anything useful.

(d) Collect the MACs of your *wired* NICs. Enable WIFI MAC filtering. Enter the MACs of the *wired* NICs into the "Not Allowed on WIFI" list.

(e) Use the strongest authentication type your AP supports. Don't use WEP.

i got a fix for phone showing in windows 8.1 before you check your network it is phone it showing in Network  go control panel then Administrative tool then services then look for  windows connect now right click on it  go to Properties then startup select disabled and click on apply then stop and ok and see your network you will not see a phone 

This might be an old thread, and for a different version of windows, but this solution still helped.  I was having the same issues, with a rogue device showing up on my network, I have set my router and firewall setting to paranoid levels, disabling SSID broadcast, filtering by MAC, only allowing certain devices connect,  reset my passwords for router log in and WiFi passwords to ridiculously length random keys including special characters, and a rogue device still kept showing up on my network.  I'm Running Win10 Home, not 8.1 but the problems described here seems to have carried over to 10 from 8.1.  this seems to have made the device disappear from my network screen so far, the device never did show up in any of my routers table, but only on my laptop, no assigned IP, or any other identifiable information, other than a MAC address, and i made sure to block that IP when i was resetting my router and firewall settings, only to have it pop back up again.  I am hoping that this solution has truly fixed the issue and has not just hidden it, needless to say i was/am feeling uncomfortable wondering if my network has been actually compromised.  I've seen a screen shot posted in this tread which looks strikingly like the rogue device that's been popping up on my network, just with a different MAC, and the type of device.  But for those having this same issue, it should definitely look familiar.   I'll post an update later if it seems that this doesn't fully fix the issue and only hides it.  It has been about an hour since i did this, and the device hasn't popped back up again, so, just maybe this will work, I'll keep fishing around online though for more info on the subject, does anyone have any interesting suggestions of where to continue looking??

Ok then we know now that Microsoft is lazy. I mean 8.1 had it where if you forced log off your user while using the modern version of snap with your desktop it would move your icons to one side of the screen. Don't think that was ever fixed due to the making of windows 10. Although yeah they will not fix it. (probably not) it just feels weird to see that on 8.1 and the most secure version of windows (W10) and have it still happen. Yes I know BLU phones are sold in America also. I was saying how some of these phones that do pop up are not sold anywhere around il.
