WiFi adapter uninstalling automatically

[CF4]

Hi

So what are the results in Ubunt Mate?

Copy and paste the script below into a text editor and save it with a meaningful name like cf4.scr and then run it in a terminal something like this ./cf4.scr

OR Just use the individual commands:-
ifconfig
iwconfig
lspci -nnk | grep -iA 2 '^[^[:space:]].*net' | sed '/^--$/d; /^[^[:space:]]/ i\\'
lsusb
rfkill list all
lsb_release -idrc
uname -srvmpio
lsmod

as and when needed.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


#!/bin/bash
clear
printf "Very BASIC Report details for WiFi. \n"
printf "NB:-Some commands might not run. \n"

printf "\n##### ifconfig ##########################\n"
ifconfig

printf "\n##### iwconfig ##########################\n"
iwconfig

printf "\n##### route ##########################\n"
route -n

printf "\n##### DNS ##########################\n"
nmcli dev show |grep DNS

printf "\n##### lspci #############################\n"
lspci -nnk | grep -iA 2 '^[^[:space:]].*net' | sed '/^--$/d; /^[^[:space:]]/ i\\'

printf "\n##### lsusb #############################\n"
lsusb

printf "\n##### rfkill ############################\n"
rfkill list all

printf "\n##### Distro Release ######################\n"
lsb_release -idrc
uname -srvmpio

printf "\n##### Modules ######################\n"
lsmod

Hi

Either the Hardware has actually failed  or you have a config problem.

I see a Gateway of 192.168.42.129

I see a DHCP IP of 192.168.42.129

Also a DNS IP of 192.168.42.129

Why?

Gateway is the entry port onto your router.

DHCP serves up/allocates IP addresses on the local network.

DNS IP's are usually external bodies, EG: 8.8.8.8. and 8.8.4.4

You have a lease time of 1 hour, at least a Day is my choice (preferably a week).

So maybe go thru your settings.

I don't use a router. I had an Ethernet cable back home which I plugged in directly, so had some settings for that. How can I know for sure that the hardware has failed? The WiFi symbol simply doesn't appear once it disappears from windows. And this time, it is gone forever. It's not even coming back after lots of restarts.

Hi

I just refreshed my PC and the wifi didn't come back. Probably the WLAN card is dead. Thing is, it also had Bluetooth, so that is gone too. Any idea where I can get a new combo card?

Update: The WiFi is back up. On its own. I did some updates last night. Last time I did the same thing, and the WiFi didn't come back.

Edit 1: Its gone, even when I didn't restart. Yep, definitely a hardware problem. I am closing this thread as resolved. Thanks for your help.

Prego.

How unfortunate that it looks to be hardware failure. Hopefully it is either a case of reseating the Wi-Fi adapter or replacing it, which should be relatively inexpensive. I hope you can find an acceptable permanent solution.

I just bought a new USB Wi-FI adapter few days after posting this thread. The Wi-Fi options for the inbuilt adapter often comes on. Unfortunately, it also had the bluetooth module, so that's gone too.
