I have a Toshiba Intel® Core™ i3-2350M CPU @ 2.30GHz × 4 laptop. Last month “Airplane mode” turned on even though I didn’t turn it on (perhaps I hit a button or something???)
So wifi is disabled and I have to use an ethernet cable instead. In settings under wifi, the message indicates “No Wifi adapter found”. So I googled and tried a few things but nothing worked. When I click on the plane icon in the taskbar and click on Airplane mode it says I need to “use hardware switch to turn off” which is FN + F. Does not work. I think this is all about Ubuntu not recognizing my Wifi adapter.
Using the command I got this:
description: Wireless interface
product: Centrino Wireless-N 1000 [Condor Peak]
vendor: Intel Corporation
physical id: 0
bus info: pci@0000:03:00.0
logical name: wlp3s0
width: 64 bits
capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless
configuration: broadcast=yes driver=iwlwifi driverversion=4.15.0-36-generic firmware=126.96.36.199 build 35138 latency=0 link=no multicast=yes wireless=IEEE 802.11
resources: irq:33 memory:f7e00000-f7e01fff
I went to the Intel website to download drivers for the Centrino Wireless-N 1000 but I got stuck on trying to figure out how to do that.
Also, my sound card is not recognized by Ubuntu…is this related??? I have no sound for about 2 days. In settings - sound there is no device listed. This has happened before and then corrects itself later.
Can someone assist in helping me figure this out? I would much appreciate this.
