Technically, it makes little difference, but nonetheless, we are talking about good practices, right now. With the amount of commands presented in your post, I would use sudo for all of them, since I am a fast typer anyway, and prefer to spend 1ms more of my time for not losing control over permissions given.įorgot to mention, that sudo su is a better practice to get to an elevated prompt within Debian. I personally change only to root, when I have to write tons of commands in a short period of time. So you don’t explicitly change to root, neither do you use sudo but it’s all clear, when you need what level of permissions. If you use su in the beginning, on the other hand, then maybe (probably) some of the commands don’t need sudo and that would be a bad practice, if used unnecessarily.Īnother thing, that I encountered often myself, what if a user did part of the work himself and only needs to execute some of the commands you are presenting? Then he should know what commands explicitly need elevated privileges and which don’t.Īn alternative way (that I personally don’t prefer, usually) is to do it like this: # mv /etc/file /etc/file.bak Your post still makes it clear, which commands need root permissions, though, even if the user decides to. So, imagine someone is reading your post and they see that every command precedes with a sudo then the user can still decide to change to root for all the command. Especially in a tutorial or guide it should be always clear which commands need root and don’t need root. Now here, what I originally wanted to say, more or It is good practice to only use root for commands that actually need it. Too many cooks and kitchens, Thanks for reminding me to chime in on this topic, since I wanted to do that some time ago, but didn’t find the time and ultimately I forgot about it.

#How to use realtek wireless lan utility install
Install Realtek rtl8812AU/8812AU USB wifi driver suĬp -R. The commands (below) are the instructions I used to install and activate the wifi drivers. I hope the new instructions method work, as I can not guarantee, it will work. I used the Ubuntu Gnome 18.04 desktop, for this tutorial, and Ubuntu allowed the use of the su command to gain root privillage (a first I must note). I do not understand why you decided to change the command line instructions.

Upon rebooting the drivers are activated, see picture No2 Now reboot your system and plug in your USB3 aerial. sudo iwlist scan | egrep -i ‘cell|chan|essid|wpa|cipher|qual’.modinfo rtl8812au | egrep ‘filen|vers|0811’.Sudo dkms install -m rtl8812AU_8821AU_linux -v 1.0 Sudo dkms build -m rtl8812AU_8821AU_linux -v 1.0 BrosTrend 1200Mbps Long Range USB WiFi Dongle AdapterĪnd now run these commands one after another: sudo cp -R.My computer nor the programs provided for TP-Link will recongnize my WiFi adapter, it will only show and register the Realtek Network Adapter.Īny ideas what could be causing this? I'm unsure of where to go from here.Screenshot from 19-58-05.png 1200×675 167 KB It was working perfectly before Win 10 build 1903 was updated for my system 3 days ago. I've completed a ipconfig renew, release, dns flush & drive reset through both powershell & command prompt I've changed ethernet settings & disabled the adapter as well I've reset my modem/router and no change, all other devices connected have great connection and speed. I've reinstalled all drivers & updated fully. I've uninstalled all system files for the adapter and WiFi profiles, and restalled. I have changed and reverted all configs for the device itself & it's profiles. I have to disable and enable my WiFi adapter every 2-3mins, or run troubleshooter. I can't maintain a stable connection to the default gateway. Second adapter driver: Virtual Wireless Bus Driver (Microsoft OS)Īlright, so I got the basic information out of the way. Network Adapter: Realtek RTL8188CU Wireless LAN 802.11n USB 2.0ĭriver for Network (WiFi) Adapter: rtwlanu_oldlC.sys I'm going to lay out what I'm currently facing as well as give some information on what I've done so far to combat the issue. I'm good with computer and usually figure out driver & device compatability issues without much problem.
