Make sure the BSSID is not set to anything (is blank) so that you can use multiple access-points and roam across the network.įirst, you will need to edit the system-connections file that corresponds to your network. NOTE: If you used the method above, you will need to do the opposite before you begin. Method 2 - roaming on a network with multiple access points like a college campus or public wifi This feature prevents your computer from switching networks. The BSSID you are connected to at that time should appear when you click on that arrow. Method 1 - for use at home with a single wireless routerįirst, connect to your basic wifi network under "Infrastructure". You should now be connected to the 5Ghz network, and you would have to explicitly do the opposite process in order to connect to the 2.4 Ghz Network. Disconnect from your network and re-connect.Uncheck the checkbox that is labeled: 'Automatically connect to this network when it is available'.Select the BSSID Matching the 2.4 Ghz Network (11:11:11:11:11:11 in this example) OR leave the BSSID empty if there are multiple other secondary access points.Click on the other 'your network name' entry.If there were 2 entries for 'your network name' in your Network Connections list, proceed with next step, otherwise go to the last step.Rename the Connection Name (not the SSID) to 'your network name'_AC.Make sure to check the checkbox that is labeled: 'Automatically connect to this network when it is available'.Select the BSSID Matching the 5 Ghz Network (22:22:22:22:22:22 in this example).(there could be 2 entries, any will do).You should find 2 entries for the network, for example: Cell XX - Address: 11:11:11:11:11:11 // This will be different in your machineĮSSID: "name of your network" // This will be different on your machineĬell XX - Address: 22:22:22:22:22:22 // This will be different on your machineĮSSID: "name of your network // This will be different on your machine Hopefully this is some useful info for you to help me further. ** (nm-connection-editor:5577): WARNING **: Invalid setting Wireless Security: Security not compatible with Ad-Hoc mode Also a error occured then in the terminal: Using sudo gnome-control-center didn't help either. However I get no pop-up asking me for a password. However when I want to change the mode from infrastructure to ad-hoc the "save" button tells me that I have to authenticate myself. "Network connections"->"Select the appropriate wireless network and click edit"->"In the wireless tab"->"Change the mode from infrastructure to ad-hoc"->"Choose 5 GHz band" I can't seem to save the settings when I change the setting and choose to use only the 5 GHz band. So I hope somebody can tell me how I tell my wifi that it should stay on the 5 GHz network and not disconnect and switch to the 2.4 GHz firstly thank you for your help. And unfortunately again they only knew the windows solution xD. Unfortunately I don't know how to do this is in either Linux or Windows. They asked me if I could acces the driver settings of my wireless card. They figured out that my wifi is switching all the time between the 2.4 GHz channel and 5 GHz channel. I told them that my wifi tears down all the time and then reconnects. Now as a coincidence there were some tech guys running around here and where asking everyone if the wifi was doing fine. This is really irritating since it happens a lot. In this building my wifi often breaks down and then restores connection again. Currently I'm in a new building of my university.
