WiFi and bluetooth don't function on Asus Vivobook 15 in Ubuntu 23.04

cn flag

I just received a brand new Asus Vivobook 15 and installed Ubuntu 23.04 on it. I noticed that the wifi connection wasn't available in the "Try Ubuntu" USB-mounted OS, but proceeded to install Ubuntu 23.04 anyway, checking the box for installing third-party drivers. I ran lshw -C network with the following output:

  *-network UNCLAIMED

The output for lspci -nnk | grep -iA3 net is:

    Subsystem: Micron Technology Inc Device [1344:2100]

After installation, there is no wifi device available. I have searched for solutions, but I have only come across an old thread about Mediatek wifi devices not working on Ubuntu 20.04 and recommending updating to kernel 5.12+ and Ubuntu 21.04.

Another set of instructions recommend connecting over ethernet (which I don't have) or bluetooth tethering (I also cannot turn on bluetooth on the laptap). The last ditch effort is to mount the Ubuntu ISO as a cdrom, but that was also not detected by the Software Sources application.

Does anyone have any idea whether Mediatek devices function on the newest Ubuntu kernels, or should I return the laptop to the seller?

Edit: As of May 13, 2023, the Mediatek MTK7902 wifi/bluetooth card is not supported in Linux 6.3 kernel.

What is the laptop model number?

It doesn't seem that the mediatek mtk7902 devices are supported in the kernel yet

I spent a lot of time trying to find a solution for this.

July 21: It seems the card is not supported:

But someone from another site shared this repo:

I contacted the emails but no one replied. seems for the USB though not for the card.

So last resort was external USB-WIFI, I tried Elecon USB-WIFI WTC117 but it does not work, so I purchased TP-Link USB Wifi TL-WN725N and it works well for now. Someone from reddit used BrosTrend AC1200 adapter and it works well for them!

I hope some can help in integrating this card because now with wifi-usb we can connect but the Bluetooth is not working.

Best of luck!

Update Aug 6: replacing the wifi_card is also an option, but it would void the warranty, check your laptops architecture first before buying a card.

I sit in a Tesla and translated this thread with Ai:

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.
