Hi ihave a old Lenovo 91z all in one pc i am trying to revive all is well so far but i need wireless drivers? Could anyone help?

Have you already installed Ubuntu MATE? If so, which version?

If UM is installed and running (albeit perhaps without a wireless connection), then you can open the "Software and Updates" app from the Administration tab of the panel menu. In the dialog, select the "Additional Drivers" tab, and let it search for drivers. Whether it does/doesn't find any, please let us know, and we'll try to help further.

As the first step I'd suggest to find out if your system lists wireless adapter in question. E.g.

$sudo lshw -short | grep -i wireless
...
/0/100/1c.3/0      wlp3s0      network        QCA9565 / AR9565 Wireless Network Adapter
...

Or

 $sudo lshw -C network
  ...
  *-network
       description: Wireless interface
       product: QCA9565 / AR9565 Wireless Network Adapter
       vendor: Qualcomm Atheros
       ...
       configuration: broadcast=yes driver=ath9k driverversion=6.8.0-85-generic

Or

$inxi -N
Network:
  Device-1: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter
    driver: ath9k

Pretty sure you have a broadcom wireless device; if so, the guide here may help: https://askubuntu.com/questions/55868/installing-broadcom-wireless-drivers

If you share the output of that command with the Community, someone may spot something specific which they can address to assist you.

Hi

$sudo lshw -short | grep -i wireless produces no output, i can see the wired LAN but nothing is mentioned about the wi-fi adaptor.

The command inxi -N shows only my ethernet adaptor no mention of wireless.

Network:

Device-1: Intel 82579LM Gigabit Network driver: e1000e

Can’t seem to see the wireless device at all. There is a option for it in the BIOS and it is turned on. I don’t see any hardware switches for the wireless. Very odd :frowning:

Let's backtrack to verify assumptions:

  • Did you open up the computer to confirm that the wireless interface circuitry is in fact present? or has it been removed?

Assuming the wireless interface IS there, if you boot from Live ISO, do you see the interface?


The command that will tell you if there are network devices is the following:

dmidecode -t 8 >dmidecode_inventory.txt

and that search in that report for entries that include "Network", as shown here:

Handle 0x000E, DMI type 8, 9 bytes
Port Connector Information
	Internal Reference Designator: LAN1
	Internal Connector Type: None
	External Reference Designator: LAN1
	External Connector Type: RJ-45
	Port Type: Network Port

You will have to look for any string that suggests wireless.

ip link show

You could also try the following (with, or without, the --short option):

hwinfo --wlan --netcard --network

Also, depending on how information was "logged", do you get anything using the command

sudo lshw -short | grep -i wi

Also, to see what you come up with, maybe poke differently with

lspci -vv -nn | grep -i net

When configured, the system should report related information using

iwconfig

Lastly, if you install hardinfo2, and look under

  • PCI Devices, or
  • Kernel Modules

is a Wireless interface reported?

According to https://support.lenovo.com/us/en/solutions/pd014555-detailed-specifications-thinkcentre-edge-91z-type-7074-7075-7077-7078-7556-7559

your wifi adapter can be

Hopefully, that's may be enough to begin search for proper Linux drivers.

I opened it up, there is a Intel Centrino N 1000 card in it, i believe it’s faulty as windows 10 didn’t see it either so i have ordered the same type but wireless AC so should work fine hopefully :smiley:
