I recently got a new laptop (a Dell Inspiron 15 5000) and have been experiencing stability issues with the wireless connection ever since I installed Ubuntu 18.04. The WiFi will disappear seemingly at random for somewhere between 30 seconds and one minute, then reappear. I have been unable to make it function any quicker by restarting the adapter using
The issues are very similar to those described in this askubuntu question. I checked
/var/log/syslog as suggested in this bug on Launchpad and did indeed find entries with
avahi-daemon[xxx]: Withdrawing address record for xx.xx.xx.xx on interface_name. The suggested solution to disable ipv6 and reboot did not solve the issues.
I am unsure how to properly diagnose the issue and progress from here.
I have tried pinging various addresses while the WiFi is not working, all of which have resulted in the following message:
ping: [xxx]: Name or service not known.
rfkill list yields the following when the WiFi is not working:
1: phy0: Wireless LAN Soft blocked: no Hard blocked: no
