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 ifconfig

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.

Likewise, rfkill list yields the following when the WiFi is not working:

1: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no

Some system information:

lspci -v:

    Flags: bus master, fast devsel, latency 0, IRQ 141

I just installed Ubuntu at my HP Pavillion H8 computer with 8gb RAM and a Intel Core i7 CPU, and for some reason I can't boot into Ubuntu. When looking in the msconfig boot menu, the only OS listed is Windows 7. Also I can't seem to find the "OS selection screen" in my boot menu. When the HP logo appears, I press esc to interrupt normal boot, and I get this screen with a lot of options. I tried all of them, and none of them seems to have a "OS Selection Screen".

I installed Ubuntu 12.04.2 using a CD.

Thanks in advance.

EDIT: I read this article, which said that Ubuntu made itself the default OS when installed. That's not the case here. I can't even get into it. http://www.psychocats.net/ubuntu/bootmenu

EDIT2: I've just checked my remaining space in the C: drive in Windows. And yes, the partition were successfull, I have less space for Windows (which means more space for Ubuntu, I think). So from that I can conclude that my installation weren't cancelled.
