Hey,I have a strange one that is really starting to puzzle me, so am looking for some assistance pleaseIn my home network we have the following:1 x ISP provided router2 x ethernet over powerline adapters2 x unmanaged desktop switches in my home office---A couple days ago we started to notice our internet speed drop randomly, and also intermittently kick us off the network completely. We put this down to the bad weather in our area. Fast forward a day or two and the issues persist, so I contact my ISP and they run some checks and find no issues on the line so must be something localI browse to my routers IP address and login with my admin credentials fine. I then close the browser and come back to it a few hours later, enter the same IP address that I connected to previously and I am presented with a different looking browser.My home internet is with Sky (UK based), and the router I am now connected to is a NOWTV router. I can also see devices showing on the dashboard devices which I have no clue what they are. A couple stand out are a Google Nest, Amazon Firestick, and a desktop PC with the default name of DESKTOP-[random-string] (i name my devices for instances like this...). I can also see a string of devices with the Device name of UNKNOWN, but I have cross referenced these UNKNOWN devices' mac addresses with a few of my own devices, and they match up.I can also see the SSID name the device is broadcasting is not mine. It is an SSID I can see being broadcast on my devices which I assume is a neighbour.I refresh the page again, and I am now on a Sky router's page, this time I am able to see my SSID, and my own devices with their correct names, but this time more UNKNOWN devices, again, this time cross referenced with the other devices mentioned previously, the Mac addresses match up with the Google Nest, and the Amazon Firestick for example. They were also all getting IP addresses which I could see when doing an IP scan on my local network range, but I couldn't ping themInstantly this sets off alarm bells, so I factory reset my router and unplug all of my powerline ethernet plugs.I have now got my router back to factory settings with a new SSID and password, and I can only see my devices. I have also done a number of refreshes of the browser, and different devices to see if I get the "other router" and I haven't seen this for the past couple of hours. So, I assume this is something to do with the powerline adapters.We are in a block of 4 semi detected/attached houses. Is it possible they were bleeding into one of my neighbours' houses networks and we have an issue with our electrics crossing over?I have done a virus scan on my PC just to make sure there is nothing malicious going off and nothing has come up.Does anyone have any suggestions or possible causes for what might be causing this? I am at a loss really; I have never seen something like this beforeEdit: I have done some digging and have repaired my powerline adapters, didn't realise this could be quite common with these things. I have also generated a new security key using the TPLink software to be safe. Currently keeping a log of all device's Mac address that I reconnect to my network, and then will cross reference again. Should this resolve the issue?
