# Solve the problem of failing to connect to certain Wifi occasionally when using NetworkManger on archlinux

I use archlinux and network-manager, and every now and then, I failed to connect to a certain wifi, while the other wifi worked pretty well. I didn’t figure out the reason, but I found a solution.

First check which wifi connections do you have.

Suppose we have a problem connecting to OpenWrt15, what we need to do is just run the following command to move OpenWrt15 to another location(Warning: make sure you know the wifi password of OpenWrt15 before moving the file, because you will need to re-input the password again later on. Usually you can find the password in the OpenWrt15 file)

Then restart NetworkManager.

And try connecting to that wifi again. You will need to re-input the password. If you don’t know the password, you can probably find it in the original /tmp/OpenWrt15 file.

Happy Hacking!
