Was in Reddit chat one to one yesterday and also another site but not sure if I can name it without getting banned. Anyway my phone has been disconnecting and I am not being able to sign into WiFi. Keep gettting error message saying ’ Connected to device, cannot provide internet’. It most likely is not a hacker or someone trying to get my IP address but just wondered how easy it was?
Can they? Theoretically is possible. In all likelihood however it’s not feasible.
The biggest concern you should have if you aren’t port forwarding is a router exploit. If your router is past end of life then the manufacturer may not be providing any more security updates for it and that could leave it vulnerable.
TP-Link a few years ago refused to patch some older routers that had an exploit because they were 10 years old. So, it happens.
Google your router name/model number and exploits to see if anything exists for it. If not then you’re fine.
