My Wi-Fi is not working on my Laptop HP Omen. Currently, I only have Kubuntu 21.10 installed on it. No Windows. My ethernet works fine. I need my Wi-Fi up and running for my class tonight. I would really appreciate your help.

These are the output I ran while doing some research:

❯ lshw -C network

Here is more information:

I tried these solutions below but still didnt work:

  1. Intel Wireless WiFi Link, Wireless-N, Advanced-N, Ultimate-N devices

  2. Linux* Support for Intel® Wireless Adapters

  3. How to load iwlwifi driver? [closed]

  4. Intel Wifi 6 AX210 - WiFi not working after Update

  5. WiFi option in Ubuntu 20.04 not appearing [duplicate]

  6. Intel AX200 Wi-Fi adapter not working

  7. Intel WiFi 6 AX200 not working on Ubuntu 16.04

Press `Ctrl` + `c` and get out of the > prompt and back to ~$ and try again: `sudo dkms status` I suspect that you have an unneeded and conflicting driver installed that we need to identify and remove.

In our chat, after searching and failing to find conflicting wireless drivers to explain this:

iwlwifi: Unknown symbol reg_query_regdb_wmm (err -2)

We decided to reinstall the package that provides your wireless driver iwlwifi:

sudo apt install --reinstall linux-modules-extra-$(uname -r)

We also found that the driver wasn’t loading and unloading properly and that iwlwifi.conf was missing. The file was written containing:

# /etc/modprobe.d/iwlwifi.conf
# iwlwifi will dyamically load either iwldvm or iwlmvm depending on the
# microcode file installed on the system.  When removing iwlwifi, first
# remove the iwl?vm module and then iwlwifi.
remove iwlwifi \
(/sbin/lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs /sbin/rmmod) \
&& /sbin/modprobe -r mac80211

Next, you said that your built-in Intel hasn’t good signal strength where it’s needed at the coffee shop. We then installed a driver for your USB wireless dongle using these instructions:

How should I go about getting a wireless connection for my desktop when I have no access to ethernet?

We agreed to blacklist the driver iwlwifi for the internal device so that the USB driver wouldn’t interfere. In order to use the Intel, remove the USB and do:

sudo modprobe iwlwifi

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
