How can I give internet priority to wifi instead of ethernet?
I have an old acer laptop (Aspire 5315-2077.) I'm using it to mainly browse the internet with while I'm using my more powerful system for gaming. I connect to the internet via wifi on the ubuntu system. I also have a wired LAN that does not connect to the internet. If plug the Ethernet cable into the LAN port on the laptop the wifi suddenly drops connection to the internet. I unplug it and I get internet. I suspect that ubuntu assumes that the wired network is faster for internet and assigns a higher priority to it. In my case, however, I need to keep priority on wifi for internet. Windows 7 allows me to assign a value to what's called an "Interface metric" no each of my connections. How can I do the same with ubuntu 13.04's connections? I have been looking for a solution for awhile and have not found it. I have found it is possible but, the person just asked if it was possible in their question and all the answers were basically yes without further explanation as to how. I am quite a novice with linux distros so, I don't have much more info about my configuration. Thank you for your help.
For Ubuntu 15.10, the procedure is more precise where your wired network does not advertise a default route.
Again, follow Network Connections into your Wired Connection and IPv4 Settings. Click Routes... and tick Use this connection only for resources on its network.
Now can you can proceed with more than one interface but retain Internet connectivity via your choice of interface.
You could try this:
- Open
Network Connectionsby searching for from Dash or open from its indicator on the top panel. - Select the wired tab;
- Select your network and press Edit
- Uncheck the option: Connect automatically.
- Now on your wireless tab select your network and be sure to keep on connect automatically.
Ok, my initial problem is solved. I figured it out myself. So you don't have to go through the stressful process yourselves, here's how to do it:
1: Click on the networks icon in the upper right corner from the desktop.
2: Click on "Edit connections".
3: Click Wired connection and choose Edit...
4: Click the IPv4 Settings tab.
5: Click the drop down menu next to "Method:"
6: Choose "Link-Local Only" in this menu
7: Click "Save" in the bottom right corner of the Editing Wired connection dialog box.
You may use your LAN and your wifi simultaneously.
