Helping people with computers... one answer at a time.
Regularly losing internet connectivity does not indicate that your router is being hacked. Start by looking at connectivity issues.
My question concerns a possible security breach to my network. When my router goes offline, and this happens quite often, would I be wrong in thinking that someone might be trying to hack into my network via the radio signal being beamed from my router? The way I usually resolve this is to unplug it and then replug the router and I can get right back online. What can cause this sudden loss of internet connection through my router? Can you think of ways of preventing this from happening again? Or the ways of stopping it all together?
In this excerpt from Answercast #97 I look at some problems with a router that disconnects regularly. It's probably not a hacker.
So to answer the very first question, yes, I believe you're wrong. No, I don't think anybody's trying to hack your router.
I think you just have a connectivity problem. I think that there are a couple of different things that can be diagnosed here.
To be honest, the very first thing I would do in a situation like this (since it all seems to be focusing around that router) is I would try swapping that router for a different one. It's very possible that the router is simply having an issue staying connected.
The other thing that I would do is, of course, take a look at your internet connection itself. It is very possible that the internet connection itself is dropping out. That can happen for any number of different of reasons. I've had it happen here at my home simply because a wire outside my house got wet.
There are many reasons that that kind of thing can happen and it's very rare that it has anything to do with a potential security breach.
So I would actually start investigating the router. I would start investigating your internet connection itself, possibly with the help of your ISP.
I do have an article, "My router disconnects every few days. What do I do?" That also covers the same kind of topic that I would refer you to.
But ultimately, I want to put your mind at rest to begin with. I really don't think this is security related at all. I really think that this is something a lot more benign; a lot more boring; and that is simply a router or a connectivity problem.
