ronj1950, I hear you.
I've installed Peppermint 5 on four hard drives at this point -- two XPs, one Toshiba Satellite Laptop, and one external hard drive connected to a USB 3 port within another Satellite Laptop.
My wife's problem is that her computer -- the Toshiba Satellite Laptop -- runs on 80% Wi-Fi strength, but PCNetSpec got her computer humming along fine on our Wi-Fi after I ran some of his commands, and that was when she was running Peppermint 4. But, at the time PCNetSpec wasn't sure about the status of the ath9k driver.
Here's my problem. I don't even know what an ath9k driver is, and, secondly, I don't know if it has been updated, or upgraded, since Peppermint 5 came out. I figure PCNetSpec may know that info now.
That's why I'm waiting to hear what to do. Things may have changed internally with Peppermint 5. I just don't know.
My wife's computer is not keeping a strong signal when watching YouTube movies. We had the same problem with Peppermint 4, but somehow PCNetSpec solved the problem. My guess, but I'm not sure, is that the ath9k driver has not been up updated or upgraded, but I thought it would be wise for me to ask before I start doing crazy things with her computer.
Incidentally, she never loses signal strength when she watches YouTube movies on her Android tablet -- which is another Linux device. I figure it's a driver problem inherited from our Ubuntu parents that has yet be solved. But that's just a guess.
Peppermint is our go to OS too -- and we were crazy about Peppermint 4, even without the security updates. That thing was as solid as a rock.
Grrr to Ubuntu for not pushing out those security updates. If they had, we would have never have left Peppermint 4. I have never used a better OS in my life than Peppermint 4.
ronj1950, you may have inadvertently solved the ath9k driver riddle for us. I just need to make sure.
Truth is, I'm tired of installing OSs these days. The four installations I've mentioned is why I'm treading lightly here. I need to give myself a break.
Thank you, ronj1950. We'll see if you've stumbled upon the solution here.
