We recently bought a new router, and we are now experiencing some issues. As the topic says, the wireless connection and the regular internet connection are not working at the same time. Not only that, the internet on the computer, which the Ethernet-cable is connected to, is not working fully. Some homepages are not accessible and some are. We made a connection setup on D-Link's homepage and after that the internet worked properly on the computer but not on wireless devices. After that we did the setup again to see if we had missed something regarding internet connection to wireless devices (for example an iPhone). This resulted in that the internet on the computer went back to the state where some homepages worked and some didn't (plus that Spotify and other programs that require internet connection stopped working).
We think that this problem might have something to do with either setups or that the modem is too old for the router to collaborate with.
This problem does not occur when the router is not plugged in.
