Hi there,

my Wifi stopped working from one day to the other. When I am trying to connect with my router at home, Easybox 804, the connection appears to be toggling on and off. The easybox recently had a firmware update and I can imagine that there's an incompatibility now. Vodafone could not help me. However, my wifi still works with all other networks and other devices connect well to the easybox. Could you think of anything that I might want to try out? Any changes to default settings? I tried to establish a static IP connection and tried 2,4Ghz and 5Ghz seperately from side of my router. How can I enable/disable one of them in fedora?

Operating System: Fedora 28 (Workstation Edition)
Kernel: Linux 4.18.14-200.fc28.x86_64

Welcome to ask.fedora! I appreciate your giving us as much information as you did, rather than simply telling us that your Fedora box has lost WiFi access and expecting us to guess what's wrong. Two tests you may be able to make that might help. First, can you connect properly via Ethernet and have a working connection. Second, is there any other WiFi hotspot you can connect to and find out if it works? The answers to these questions will probably tell us where to look next.

Hi, try to make a new connection to your home router, i.e. remove it in network settings (or use 'forget this network' button), and connect to it again (providing current password). Also make sure your system is up to date, kernel and firmware updates can improve your network card behaviour.

Check your router's settings to see whether it's using same settings (SSID / password) for 2,4 and 5 GHz.
