TP-Link wireless adapter suddenly not working on Ubuntu 18.04.6

ar flag

Fair warning that I am fairly new to Linux so I need everything explained to me like a child. Apologies in advance for my ignorance.

I recently installed a TP-Link wifi adapter, TL-WN725N. Installing the driver was a full-day operation, with me trying every command I could find online in the hopes that I would eventually get it to work. It did eventually work, but I couldn't tell you how or why, and I could easily have installed something incorrectly by mistake.

The adapter worked perfectly for about three weeks, and suddenly today it doesn't. When I check the devices, it does recognize that a wireless adapter is plugged in, but the adapter is no longer connecting or flashing as it used to. I have no idea why, as it was working fine yesterday. I installed the suggested software and firmware updates, but that hasn't solved the issue.

Please advise.

not sure if I can answer why your adapter does not work but, based on your description, I would remove the adapter and see if it lights up or functions on another USB port or on another computer. Also test your USB port, plug a USB thumb drive to see if it opens it. I would also check which driver you installed as the BETA driver may have unknown bugs. There is also a question of which hardware version you have. v1,2, or 3enter image description hereenter image description here This info found here:

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.
