Perhaps you need execute `sudo deepin-feedback-cli` or @admin.
Some of us got the same problem.

I encountered the same issue since the September 8 update pack. I suspect that the network-manager update is causing the issue. Also the wired connection does not work anymore. Strange thing is that I get an IP from my router and the configuration looks OK from the network config manager view.

@ Yuri, thanks for the suggestion. I posted the output to http://feedback.deepin.org/

Same here. There's a big issue related to the last network-manager upgrade. Something's broken with DNS resolution

Thanks, but that's not the issue, problem occurs with wired network too...

I  have the same problem,too.   since the lastest update.   my wireless  is  RTL8187.  

If this is really a DNS problem,you can temporarily fix it like that:
sudo gedit /etc/resolv.conf
Delete the content of the file,then add this two lines:
nameserver 80.80.80.80
nameserver 80.80.81.81
Do NOT restart your connection,it's very likely that this will restore the old /etc/resolv.conf and your DNS stops working again.

Please edit the file '/etc/NetworkManager/NetworkManager.conf', comment the line 'dns=dnsmasq', then reboot.
