Identifying... No Internet Access

My Windows 7 laptop suddenly, out of the blue, started having network problems.  When trying to connect to any of our several WiFi networks, it gave the error "Identifying... No Internet Access."  Connecting to a wired ethernet connection worked just fine.  After hours of frustratingly chasing wild geese, I finally solved the problem.

Not dead yet.  Just really busy.  Sorry for the moment of silence.

Enlarging a live mdadm ext4 filesystem

My computer runs a several RAID5 arrays on a handful of drives of various sizes.  I recently replaced one of those drives with one of a larger size, which allowed me to add more space to one of my smaller RAID5 arrays.  I tried to enlarge the RAID filesystem without rebooting, which should theoretically been possible, but I couldn't make it work.  I eventually broke down and rebooted so I could finish the process.  Here's the blow by blow steps.

Plex Media Server on Ubuntu Linux

I had lunch recently with a friend who, like me, doesn't pay for TV service.  All of our viewing options are over the air or off the Internet.  During that discussion, he told me about the Plex Media Server that he uses to manage many of the Internet video options in his house, as well as many of the DVD movies that he owns.  It sounded like a pretty slick system, so that night, I installed it myself on my Ubuntu Linux 14.04 home computer.

Installing a rooted stock ROM on a Spring Galaxy Note 2

I've had my Samsung Galaxy Note II phone for a couple years now, and for the most part, I love it.  It ran Android 4.1.2 when I first got it.  Upgrading that to Android 4.3 went badly, and the custom MK4 ROM that I installed to recover from it was a constant frustration.  When Samsung finally released Android 4.4.2 (KitKat) for the Note 2, it wasn't long before custom ROM's based on it were available in the wild.  I chose to stick with a mostly stock setup, but rooted, and without Knox support.  Details of the process follow.

Rooting a Samsung Galaxy Note 10.1 2014 tablet

My son just bought a good used Samsung Galaxy Note 10.1 (2014 edition) tablet (model SM-P600).  Since it was already out of warranty, our first order of business was to root it so we could get good backups.  I've rooted several Samsung devices in our family already, so the process was pretty straightforward.  Here's how it works.

Fixing a linux software RAID degraded at boot

I have a lot of storage space on my Linux desktop box at home.  The bulk of it is spread across two mdadm software RAID 5 partitions:  one 3-disk array and one 5-disk array.  Occasionally, I've found that the 5-disk array comes up in degraded mode after the machine boots.  After much frustration, I think I finally found the fix for this.
