OS: Fedora 26

03:00.0 Network controller: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) (rev 01)

Very odd behavior. ISP had an issue and lost full access to the internet.

Once ISP connection was restored, my fedora 26 laptop still cannot connect to the wireless network it could connect to prior to the isp outage.

Note that other clients have been able to re-connect to the wifi without any problems. However, none of these connected clients are linux. They are windows, android and ios clients. So i know my router is working fine.

I tried to renew my lease via dhclient -r virbir0. Still does not connect.

If I take my laptop to a different wifi network it had connected to prior, it automatically reconnects just fine. So i know my wifi on the laptop is working.

I checked the passwd on the wifi and its good.

Its just my home network!!! Cannot connect to wifi anymore!!! Not sure what to do

Not sure if I should do anything with modprobe ?

tia,

Sunil

Without knowing your network settings in more detail we can hardly assist you further. But from the provided info it would seems like you have some network configuration issue on that laptop. Where does this virbr0 interface comes from? Do you have some virtual machine bridge configured on the laptop?

I would recommend going into network settings for this machine and undo any custom things you might have configured on it in order to bring back the defaults.

To help us understand this further you can provide ip addr show output as well or screenshot of your network settings.

Sure. Will provide what ever info is needed. I was surprised to see "virbr0" ifce as well. But dont remember what the wireless ifce was named before this. I have not installed any os virtualization. PS. syslog below shows trying to authenticate. I havent changed my ssid passwd. My other non linux devices re- connected just fine.

If i missed any settings info, pls let me know and I will provide.

This is the output from ifconfig: I am currently connected via a ethernet cable.

masteroman: Sorry, i had installed vpn software a long time ago. Not sure if that was what you were alluding to? It had been working fine all this time. I will have to figure out how to un-install that software and check if its any better afterwards.

I were alluding to the virbr itnerface being created by the some virtualization software. virbr is usually created by virt-manager, virtualbox and similar programs. Your wireless interface is still wlp3s0 , but seems like it could be a part of virbr interface when you connect to the wifi.

You're currently connected to the network via cable, right? Because I can see enp5s0 is active and has IP assigned to it.

Can you re-create issue and while the issue is active provide that output since that may give better info..
