Dell Laptop Internet Problems?

I bought a new laptop from Dell 2 weeks ago. The Wi-Fi does not work really well in my home. In the university, the connection is always made immediately, at home (Unitymedia + Huawei router), I must always go through 5 times the troubleshooting, until it works… As an error message comes: Problems with the network adapter… I already reinstalled the driver…

can I do anything else?

Maybe your router is too bad?
