Reconnecting without restart impossible in Mint 17.1 Xfce

[palbertsma]

Hi,

After loosing connection with wifi, just by accident, or after being in sleep modus, it is impossible for me to reconnect without having restarted linux mint 17.1 xfce!

There must be a way to reconnect without the cold restart!

Please help, for which many thanks in advance!

Paul

Hi,

May I draw the conclusion that this IS a bug in Linux Mint (17.1 Xfce), and therefore cannot be solved?

If so, does anyone know a workaround for this? E.g. is there a third party wifi manager out there, that can be installed and overwrites Linux Mints own somehow buggy Wifi manager?

Please help!

Looking at your mintwifi output, I would say that everything seems to be working perfectly. Thus said, I would recommend you take a look at the settings in your Router's configuration, and pay particular attention to what the dhcp timeout settings are.

[palbertsma]

Richyrich, thanks for your reply.

First: in Windows XP, 7, 8 and 8.1 I use the same computer with the same network card and router, and reconnection works flowlessly!
Second: my router's configuration only says that the connection mode is DHCP: this cannot be changed in any way. It says nothing about a timeout of DHCP: also look at the attachment. Although the DHCP seems changeable, it is not.

Hopefully you have enough information to help me out; thanks in advance!

One of your mintwifi settings show that it is using ipv6, this isn't needed, clicking the network icon in the panel, and entering the settings will allow you to set it to "Ignore". But this shouldn't be causing you to lose the connection . . What drivers are you using? The following terminal command will tell us:

Code: Select all

inxi -N

This is the output of inxi -N:
