Wireless Connection Wifi On My PC

I bought a wireless pcie or wifi card from Lazada the other week. It's an Ralink pcie card shown below.

My general notion in networking is that this card should work in my Arch linux GNOME setup. Well, yes and no. I installed the pcie card to my motherboard. My computer recognized the new hardware. I checked if the proper drivers are installed.

$ lspci -k
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 11)
    Subsystem: ASUSTeK Computer Inc. Device 859e
    Kernel driver in use: r8169
    Kernel modules: r8169
04:00.0 PCI bridge: ASMedia Technology Inc. ASM1083/1085 PCIe to PCI Bridge (rev 04)
system: Ralink corp. RT3062 Wireless 802.11n 2T/2R
    Kernel driver05:00.0 Network controller: Ralink corp. RT3062 Wireless 802.11n 2T/2R
     Sub in use: rt2800pci
    Kernel modules: rt2800pci


And they are being used, rt2800pci as shown.

But, when I tried activating the connection, it threw me a lot of error message. It went through the motion of trying to connect, and authenticating but it fails. I tried googling the problem. Oh and I also installed dnsmasq in the process of troubleshooting it. I don't have any idea why dnsmasq is needed here.

I was fiddling with netctl commands to no avail. I am running out of ideas.

After a day or two of leaving it to simmer for a while this greeted me today.

Password Issues On Ubuntu Login

I found myself unable to enter my login credentials when prompted to do so in Ubuntu. I think I might have changed it then forget about it. I've been running the current session for more days than I should have. I forget. So what's the solution to my problem. How do I get in to my system now? It involved getting into the grub menu somehow. I am uncertain as to how to do that exactly in your system. So there's a couple of ways to do it (finger's crossed). When booting at system start, use the esc key or the shift key. The first one worked for me. The timing is key. Wait until the bios banner shows then hit the esc key once. I am using Ubuntu 22.04.4 here. I have a current version of grub. The grub menu will give you options and the one you want is: root. Yes you want root privileges to set the root password. It should give you a terminal access where you can issue commands. Type: #mount -rw -o -s remount / ==> this command mounts the filesyste...

Pacman Has to Get Better

I finally got my printers working. I got cups (and cupsd in the /etc/rc.conf) I installed hpoj and a group of printer drivers. So to get my Arch linux to recognize there's a usb printer connected to my system I have to run a daemon (ptal-init setup) and include it in /etc/rc.conf. That finally enabled (after a reboot) my GNOME control center to acknowledge that there is indeed an HP-3900 at the end of my usb port. The real personal story behind my saga with a printer is pacman. It is now throwing 'network not reachable' everytime I start it. Every download and sync. I ran --debug and ping ip addresses and so far I will conclude that it's a really really slow ftp server. The server is so slow pacman is timing out connections. It's unusable guys. My first rolling release distro and I've decided that Arch rises and falls with the performance of their package manager. Great distro for the DIY community. But sorry I can't recommend Arch linux to my mother who jus...

Webapps in Unity

So it has been 4 months since Ubuntu 14.04 came out. This is LTS and supported for 6 years by Canonical. The first mobile device with Ubuntu pre-installed is promised to come out later this year, 2014. It's time to check out how the apps perform so far. It is a good idea. I use Gmail and Twitter and Facebook. Why not a webapp in a desktop? So I start the Twitter and Gmail webapp. So far it has crashed my computer 6 times. Not a very good sign. On the other hand it does work but not as stable as opening them in Firefox. -- Use my PGP key if you want to encrypt your replies/messages to me.
