In this case a Feb Smart card because I found it listed in an Ubuntu compatible list.

sudo lshw returns

sudo lshw -class network produces

I have:

  • downloaded and installed the latest version of the firmware from Intel
  • tried the Atheros drivers through Ath10k. They're all now blacklisted.

Only the iwlwifi driver got the Wifi and Bluetooth icons to appear on the toolbar.

When I try to connect to my Wifi netowrk, I get the password screen but the connection always fails. During the initial connection

sudo lshw -class network -short && nmcli device status

returns

When the authentication screen is presented,

After entering the password H/W path Device Class Description

The connection always fails. "neonjohn" is the SSID of my network. The antennae are about 4 ft away from the router. I've reset the router several times.

With the bluetooth, the menu appears but it does nothing when I select "devices" even though I have a BlueTooth speaker sitting next to the antennae.

This is the third day I've been working on this problem and I'm at my wit's end. Please Help

More information

If I reboot and uninstall the driver and then reinstall it, the WiFi connects immediately.

sudo modprobe -r iwlwifi Producing

remove (/sbin/lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs /sbin/rmmod) && /sbin/modprobe -r mac80211 rmmod mac80211 rmmod libarc4 rmmod cfg80211

then sudo modprobe iwlwifi producing

nsmod /lib/modules/5.4.0-65-generic/kernel/net/wireless/cfg80211.ko insmod /lib/modules/5.4.0-65-generic/kernel/drivers/net/wireless/intel/iwlwifi/iwlwifi.ko

The WiFi connects immediately.

Anyone have any thoughts about this? Thanks John

UPDATE 02/11/2021

Taking the above action disabled my wired ethernet port. I had to remove the driver to get my wired connection back.

I have now purchased and returned 3 PCIe cards recommended as being compatible. A WiFi dongle that worked on 16.04 also fails. It looks like Canonical screwed the pooch on networking on this release.

Two questions:

Does anyone know of a PCIe combo wifi/bluetooth card KNOWN to work with 20.04 LTS?

Has the networking been fixed in 21.04? I want to stay with LTS releases but I also want networking.

Thanks, John

  • Does iwconfig show power management on when it won't connect? – Jeremy31 Feb 08 '21 at 11:28

I never solved this problem. I bought and returned 3 other linux-compatible PCIi cards. None would come up. Neither would an WiFi dongle. Looks like wireless networking is really screwed up on this release.

Anyone know whether 21.04 solved the network problem?

Thanks for all the help

John
