The last time I booted my computer I could no longer access the wifi adapter, after some looking around I realized that Ubuntu was not finding any Wifi adapter in the system, it was working fine until I booted my system I'm guessing it was because of one of the internal updates which I get every day. From other posts, I've seen people asking for output of
lspci -knn | grep Net -A3; rfkill list
Which is:
03:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8188EE Wireless Network Adapter [10ec:8179] (rev 01)
Subsystem: Realtek Semiconductor Co., Ltd. RTL8188EE Wireless Network Adapter [10ec:8197]
Kernel modules: rtl8188ee
I have tried a lot of approaches mentioned on various platforms including the questions answered for an almost a duplicate question on askubuntu and none of the approaches solves my problem that is why I needed to ask a new question. There isn't any problem in the Wifi adapter physically because I have Ubuntu dual booted on my desktop and it works fine in Windows. Also, I have connected the computer with an ethernet cable from the wifi router and it works fine as well.
sudo modprobe -v rtl8188ee
or does it give an error? – Jeremy31 Jul 21 '19 at 19:23sudo modprobe -v rtl8188ee
gives the following error.insmod /lib/modules/4.15.0-54-generic/updates/dkms/rtlwifi.ko modprobe: ERROR: could not insert 'rtl8188ee': Unknown symbol in module, or unknown parameter (see dmesg)
And this is the answer I followed on AU. link
