Link to Check Your Home Router
Here is a link to an online utility that can check your router to see if it has been hacked. In the last couple of months, the number of routers that have fallen victim to certain vulnerabilities has risen drastically. I will add that this appears to be more of an issue with European countries, but for the sake of a minute to run the check, it is worth it as these compromised routers can give an attacker full access to your home network and all of the devices on it.

The page explains what is going on and the button for the utility is about half way down – once again, just for the peace of mind, I would urge you to run this. The site also gives some suggestions if it comes back with a vulnerability detection.
