Regular blog here, 'microblog' there

Many of my traditional blog post live on this site, but a great majority of my social-style posts can be found on my much-busier microbloging site at updates.passthejoe.net. It's busier because my BlogPoster "microblogging" script generates short, Twitter-style posts from the Linux or Windows (or anywhere you can run Ruby with too many Gems) command line, uploads them to the web server and send them out on my Twitter and Mastodon feeds.

I used to post to this blog via scripts and Unix/Linux utilities (curl and Unison) that helped me mirror the files locally and on the server. Since this site recently moved hosts, none of that is set up. I'm just using SFTP and SSH to write posts and manage the site.

Disqus comments are not live just yet because I'm not sure about what I'm going to do for the domain on this site. I'll probably restore the old domain at first just to have some continuity, but for now I like using the "free" domain from this site's new host, NearlyFreeSpeech.net.

Fix for Ubuntu 16.04 with Qualcomm Atheros AR9485 WiFi adapter and Time Warner modem

Update: This issue went away in a normal install. I presume that the added firmware during installation took care of the WiFi issues.

Original entry begins here:

I was just saying how compatible my now-3-year-old HP Pavilion g6-2210us laptop is with Linux at its advanced age. Everything in Fedora works with no tweaking, no modifications.

So I wanted to try Ubuntu 16.04 (with Unity even). First I used Unetbootin to put the ISO on a USB key. That didn't seem to work, though I had enough trouble getting the display to work that the problem could very well lie elsewhere.

So I used dd to put the ISO on the USB:

sudo dd if=/path/to/ISO of=/dev/sdb bs=8M

That worked. I booted into Ubuntu 16.04. Then I still had a blank screen. I tried to switch to a virtual terminal with ctrl-alt-F2, and eventually hit all the ctrl-alt-number combinations, after which ctrl-alt-F7 got me the graphical desktop.

That very well could have worked with my Unetbootin-created bootable USB stick.

Meanwhile, once I had Ubuntu running, I could connect to my older Netgear router running WEP but not to my newer Time Warner modem/router (I can't remember the brand or model) with WPA.

My laptop uses the Qualcomm Atheros AR9485 WiFi module, and that was where I looked first for ideas.

I found something pretty quickly.

In a terminal, enter this line:

 echo "options asus_nb_wmi wapf=1" | sudo tee /etc/modprobe.d/asus.conf

After that, I was able to connect to my WPA-enabled router, and all was well.

I didn't think I needed to resort to this kind of filthy hack in 2016 and on a laptop that has been in the wild for three full years.

But I did.

I'm not sure what I think of Ubuntu 16.04 just yet. I'll need to do a Citrix test. Running the big Citrix-enabled application that I use for my day job is pretty good in Xfce but horrible in GNOME Shell in Fedora. If it is in any way better in Unity, that will carry a lot of weight.
