Mint 15 wifi problem Realtek RTL8723AE

Post by maramaric »

I am using linux mint 15 with mate desktop and I am trying to connect to a wireless network. When I write user name and password and press Connect I get the following message:
No certificate Authority certificate chosen
and then I click Choose CA Certificate and it gets me back to the user name and password window.

The computer is Toshiba Satelite C855-242

When I run mintWifi i get the following

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service smbd reload

Since the script you are attempting to invoke has been converted to an

Not related to your wifi problem, but are you considering to upgrade to Linux Mint 17 soon? Linux Mint 15 has reached end of support in January this year, meaning since then you no longer get upgrades for security issues found. Especially your web browser is vulnerable and you shouldn't use Linux Mint 15 online for anything serious like online banking. Linux Mint 17 is supported for 5 years.

As said in the previous reply , try using either Mint 13 or 17 which are LTS (long term support) versions.

But if you want to stick to Min 15 , consider this reply :

The guy in this thread might have struck gold : http://forums.linuxmint.com/viewtopic.php?f=53&t=171718

My theory is the following :

With the latest release (maybe the earlier ones too) ,have the opensource wifi drivers gained the upperhand when assigned to hardware. The drivers from the vendors don't play along anymore.

So you could use the technique described in this thread to blacklist the opensource driver,and next to it install your own driver that is better made for it,and force the system to use that driver.
