No internet connection when wifi is connected

[X J]

I'm using the newest version from ppa.
The following log doesn't look like an internet connection error to me.

chroot apt-get -y update
chroot: cannot change root directory to 'apt-get': No such file or directory
Purge the GRUB of sdb1
SET@_label0.set_text('''Purge and reinstall the GRUB of: sdb1. This may require several minutes...''')
SET@_purgewindow.set_title('''Boot Repair''')
SET@_purgewindow.set_icon_from_file('''x-boot-repair.png''')
SET@_label0.set_text('''Purge and reinstall the GRUB of: sdb1 (tst). This may require several minutes...''')

hi Jon,
it's strange you cannot ping google.
if you encounter this issue again, you can use the 'Disable internet check' option in the Advanced Options as a workaround.
