Just a few minutes ago when I tried to use the Google search engine it took me to a page ASKING me for a captcha to prove I was not a robot. It also explained that it detected unusual traffic from my IP address. I tried to use the engine about three or four times before it disappeared and I could use Google normally again.

Since it went away does that mean I can ignore it or should I be concerned that something could be wrong with the router or any of my network devices?Anyone ELSE using your network/internet CONNECTION to do stuff that would flag it?My parents and sister. I'm pretty sure they don't do anything to do that. My sister has a boyfriend who has a tablet he SUES here. I think since he uses it here he must be using the network. It's been like that for a couple of months now and I have no idea what he does on it.

We also have a neighbour who knows our password but he lives like fifteen minutes away from here.See Here...I always get that message when I go to Google using Tor, which is why I chose DuckDuckGo, which doesn't seem to mind.
I don't use tor or any VPN. Which makes this especially odd. But what's even odder is that they just stopped. I can use google fine now with no message like it from them.I got a feeling more people are using your internet than you think...If this is the case what is your advice? And how can I confirm for certain that our internet is being sponged?Put a router password on it and give it only to family members.Check your settings and software for vulnerabilities. It is very risky to keep your internet so open. Put strong passwords everywhere you can and change privacy settings. The router is a device that can be exploited. Change your password occasionally and share them with your family membersKinda what was suggested...back in February...
