Wifi Speed drops miserably

vn flag

Device: Dell Inspiron 15 3000 series Ubuntu: 20.04 LTS (64-bit)

Since today in my Ubuntu Laptop, WiFi internet speed drops to minimum. And on reconnecting, connection restores normalcy but only to go down again after a few minutes.

I don't think it is a WiFi problem, because speed is consistent in other devices (Windows and Android).

Look at the logs! `sudo journalctl -b 0 -u NetworkManager`. Read `man journalctl`.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
