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.
