My wifi internet connection is now showing from left clicking the icon in the bottom right hand corner, should I disconnect the wired cable and try it?


Many thanks,
degsy

Okay, are you now able to create a working wireless profile by removing the ethernet cable, then clicking on the networkmanager icon in the system tray, then clicking your network name and entering your password ?

if so, does it survive a reboot ?

Spoiler (click here to view / hide)
[close]


When I try to connect by left clicking on the icon, a list of available networks is shown, I click on "degsyonline" but all that happens is the icon "circles" for a while and then says unable to connect. It doesnt even get as far as asking for a password.

Hi Degsy, could you please remember to encapsulate terminal outputs with the Insert, Code # function.  For extra long outputs, please use the Spoiler, Sp function.  It preserves the original format of the output.  This makes it easier for future visitors to relate to their own issues.  These functions are found in the forum editor, above the,  :-[ Embarrassed and  the :'( Cry emoticon respectively.  I've done this for you this time - many thanks  ;).
Backup! Backup! Backup! If you're missing any of these -  you ain't Backed Up!
For my system info please L/click HERE.

Hi Mark,
Sorry for delay in getting back to you, however, on booting up today I tried the left click on the network icon and then clicked "degsyonline" and the laptop connected wirelessly, have disconnected the wire and am now using wifi to post this response.
Will check that this survives a reboot and then will mark as "solved" providing it does survive the reboot.

May I thank you again for your advice and patience when dealing with the problems we beginners throw at you,

cheers and regards,
Degsy

Hi Mark,

Many thanks again, glad to say have rebooted and the laptop does connect to my wifi right away, so I think we can consider the topic solved.

Thanks again, my grandson will be delighted to have his laptop back and working properly.

Regards,
Degsy
