home WLAN does not work with Ubuntu 16.04 on Thinkpad

[Pooja Saxena]

Hello,
I am working on Ubuntu 16.04 with the following details [1], which is a fresh installation on Thinkpad Carbon laptop.
Since day 1, I could not manage to use my home WLAN for things like wget, update packages etc.
Here is one example trying to install some package using my home WLAN [2], and instant output of trying to install the same package after switching to my Mobile data [3].

I do not see a reason why it should happen, specially when this works for my other personal laptop (DELL).

Any suggestions to dig it further is appreciated.

Many thanks,

Pooja, you are using an unsupported mainline kernel 4.19.0-041900rc4-lowlatency. If you boot back to the official v4.15 kernel do you still have the problem?

[Pooja Saxena (nrjrasaxena)]

Thanks Anthony,
I could try doing that.
In case you have the instructions/help-page for installing v4.15, please let me know.

Thanks again,
pooja

[Anthony Wong (anthonywong)]

Pooja, you don't really need to install that explicitly, since it is the default when you installed 16.04.5, unless you have accidentally removed it. Can you see that in the grub menu?

[Pooja Saxena (nrjrasaxena)]

Hello,
thanks for the reply.
well, I had loads of issue in installing a stable working Ubuntu in Thinkpad and therefore also I went through series of problem fixing solutions. In short, there is a higher chance that I played around with Grub, but can not confirm. Besides, I am not much into Grub settings.
Please find the info of my Grub, and guide me further which one I have got and which one I should have [1].
Also, one more important requirement for me is that I am running my work-windows 10 in Oracle VM, that should also be compatible with the Grub.

Many thanks,
pooja
