Ubuntu: Why is my wireless very unstable, even after trying Wicd?



Question:

Here is my script output.

I'm a brand new Linux user. I installed it on an old Windows 8.1 machine. Wireless Internet will be connected for a minute or two, then I will not be able to load Web pages. I tried installing Wicd Network Manager, but it didn't remedy the problem.


Solution:1

You need to get an updated driver, with an internet connection do:

sudo apt-get install --reinstall linux-headers-$(uname -r) linux-headers-generic build-essential git dkms  git clone https://github.com/pvaret/rtl8192cu-fixes.git  sudo dkms add ./rtl8192cu-fixes  sudo dkms install 8192cu/1.9  echo "blacklist rtl8192cu" | sudo tee -a /etc/modprobe.d/blacklist.conf  

Reboot


Solution:2

Run the command iwconfig

Find what your wireless connection name is and run sudo iwconfig wlp3s0 power off

Example:

ee@sys6:~$ iwconfig    wlp3s0    IEEE 802.11abgn  ESSID:"5ghz"              Mode:Managed  Frequency:5.805 GHz  Access Point: E0:3F:49:93:3F:14               Bit Rate=390 Mb/s   Tx-Power=22 dBm               Retry short limit:7   RTS thr:off   Fragment thr:off            Power Management:on            Link Quality=57/70  Signal level=-53 dBm              Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0            Tx excessive retries:0  Invalid misc:74   Missed beacon:0    lo        no wireless extensions.    enp4s0f2  no wireless extensions.      ee@sys6:~$ sudo iwconfig wlp3s0 power off    ee@sys6:~$ iwconfig  wlp3s0    IEEE 802.11abgn  ESSID:"5ghz"              Mode:Managed  Frequency:5.805 GHz  Access Point: E0:3F:49:93:3F:14               Bit Rate=390 Mb/s   Tx-Power=22 dBm               Retry short limit:7   RTS thr:off   Fragment thr:off            Power Management:off            Link Quality=57/70  Signal level=-53 dBm              Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0            Tx excessive retries:0  Invalid misc:74   Missed beacon:0    lo        no wireless extensions.    enp4s0f2  no wireless extensions.
