dont know if this is enough to get started, but any suggestions would be brilliant, thanks in advance

[JeremyB]

You might need to

Code: Select all

echo "options iwlwifi 11n_disable=8" | sudo tee /etc/modprobe.d/wifi.conf

and reboot

[<bill>]

thanks for getting back.
i tried that and got

"options iwlwifi 11n_disable=8"

reboot and tried wicd to connect- still no go - "validating" then stops with "bad password"
i checked that, all ok. i see others have similar problem.

i see that in wicd properties the password is set under
WEP(Hex[0-9/A-F])

is that relevant

many thanks

[JeremyB]

Did you disable the Linux Mint Network Manager?

[<bill>]

not intentionally, but i have been trying for a while to get wifi (sorry),
looked in software manager (searched "network manager") and see that;
wicd
wicd-gtk
python-wicd
wicd-daemon
are all installed, none others. but i realise installed does not necessarily mean enabled. how do i check please.
thanks for your patience

PS i tried

cat -s /var/lib/NetworkManager/NetworkManager.state

and got

NetworkingEnabled=true
WirelessEnabled=true
WWANEnabled=true
WimaxEnabled=true


Any help to you?

[<bill>]

ALL SOLVED!

having done all above, I then put the password in WPA, and not WEP and it worked. dont understand why but it did (others have had same thing)
thanks for looking

Great that you got it solved as I was led to believe that wicd worked with WEP better than the standard network manager

[Pjotr]

Good! WEP sucks anyway; WPA is much better. WPA2 is optimal: can you set that as well?
