I have a Galago Pro running Fedora 29. The computer went into suspension because of low battery. Now, Fedora does not detect the wireless adapter -- meaning the gui manager returns "No WiFi adapter found...". The adapter was working correctly prior to the suspension.

rfkill list shows no hard or soft block.
lspci shows:

03:00.0 Network controller: Intel Corporation Wireless 7260 (rev 73)
    Subsystem: Intel Corporation Dual Band Wireless-AC 7260
    Flags: bus master, fast devsel, latency 0, IRQ 32

    Kernel driver in use: iwlwifi

ip link shows:

link/ether a0:a8:cd:df:ff:84 brd ff:ff:ff:ff:ff:ff

ip link set wlp3s0 up has no effect

I have tried a hard (cold) reboot, restarting networking, and restarting network manager.

Run an

rfkill list

followed by an

rfkill unblock x

where x is the correct index taken from the list.

  • You did see that rfkill list shows no blocks, right? I still need to run this?

  • Sorry about that. Read too fast. I thought it was a power saving feature, disabling the wifi. Does the keyboard have a function key to enable wifi?

  • NP. No keyboard function, nor hardware switch

  • It's not in Airplane mode?

  • No, not indicated anyway. Shouldn't rfkill list show that? I'll double check that bluetooth is working, just to be certain

Posting for anyone who comes across this thread in the future.

It turns out that the low battery suspension must have caused some file corruptions. I did a DNF upgrade, and afterwards everything works correctly.

Thanks to all who helped.
