[SOLVED] wifi detects network yet can't connect

[marmaladeskies]

Wifi was operational a few months ago but I only logged into it yesterday. Although the system detects wifi networks and notifies me that the connection is established, I am not actually online.
I've also tried hot spot and tethering but still cannot connect. I'm pretty sure that connecting it directly to the router would result in the same.

File is too large to import so here are a few highlights:

sudo iwconfig shows wlol with SSID, strong signal level.

sudo nmcli device shows connected state

uname -m X86_64

Result of pinging google.com -
Name or service not known

Whereas pinging 68.105.28.11 was successful.

Any pointers would be appreciated.

Is it a DNS configuration problem, am I missing a network update.

[marmaladeskies]

Sorry, my typo:

mokutil --sb-state
Secure boot enabled

[sleeper12]

Disable secure boot in Bios.
Also, turn power management off:

Code: Select all

sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Reboot

[marmaladeskies]

Disable secure boot in Bios.

Code: Select all

sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Reboot

Manually disabled secure boot and all power management options in bios. Reboot. Still same result

[sleeper12]

Let's see how this looks now:

Code: Select all

iwconfig ; mokutil --sb-state

[sleeper12]

Do you still have Windows on that machine?

[marmaladeskies]

Do you still have Windows on that machine?

No, it's a dedicated Linux OS, refurbished laptop - and I had no connectivity issues with it previously. It's been sitting idle for a few months though until I fired her up yesterday.

[sleeper12]

Can you confirm that these both show as off now:

Code: Select all

iwconfig ; mokutil --sb-state

So no wireless extensions.

You can try shut down & unplug the machine, remove battery (if possible), hold the power button down for 40 seconds, & try wifi again.

For some reason I can't remove any of the screws, bar the center one so removing the battery is a problem. There doesn't appear to be an option in bios to temporarily disable the battery so my only alternative is to run down the battery and start from AC.

[sleeper12]

Just try it then without removing the battery.

Just try it then without removing the battery.

Same result

Sometimes the problem may be very basic:

Any switches (fn, bios, simple switches on your unit) turned off that should be on?

Are you using a VPN, maybe there is a killswitch?

[marmaladeskies]

Are you using a VPN, maybe there is a killswitch?

Bingo!!!!
My God, I feel so dumb but thankful also for your advice.
nordvpn set killswitch off...that's all it took. I didn't even know whether it was activated or not but it sure did it's job

[sleeper12]

Ok, good. Wish I thought of that sooner, but the changes you made earlier should be fine.
