Hi there.

Just installed Ubuntu. The laptop can see the router but just can't establish connection, everything seems to be in order in the setting yet it can't load anything up in firefox

Hi,

there is a bug in 17.04. Please run these 2 commands and reboot

echo -e "\n[device]\nwifi.scan-rand-mac-address=no" | sudo tee -a /etc/NetworkManager/NetworkManager.conf
sudo sed -i "s/wifi.powersave = 3/wifi.powersave = 2/g" /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

HI, thanks for the quick reply.

I placed them into terminal and then rebooted the system and now I have no wifi bar in the top right. Also when I go into system settings then to network I get "The system network services are not compatible with this version". I have the most up to date version .

What codes should i have got in return?

Please follow this guide for the wireless script and show the outputs (c/p into a txt file)

I'm a newbie running Ubuntu 17.04 as a "virtual machine" under Virtual Box (Windows 7).

(1) how is copy/paste done between Win clipboard and Ubuntu terminal ?
(2) is ** [device] ** to be entered as shown or is an existing device to be entered instead ?

Thanx.

Thread moved to Virtualisation.

Yes, entered as shown. Just c/p these commands into a txt file. Normally, virtualbox (if used) now can work with c/p or drag/drop txt files
