Networking for dummies (like me): September 2009 Archives

I always pull the trigger too soon when declaring success with a new WiFi adapter/software/hardware combination, and I'm hoping that's not the case with the Airlink 101 AWLL3028, Ubuntu 8.04 LTS and my aging Toshiba Satellite 1100-S101.

But today I first had trouble connecting with my WEP encryption key (I know I shouldn't be using WEP ... and I will change to WPA2 once I resolve a few issues and get the rest of the house's computers on board ...).

Then when I finally did connect (had to reboot) I had the typical screen-freezes-and-ctrl-alt-backspace-AND-ctrl-alt-delete-have-no-effect-so-I-have-to-do-a-hard-reset.

That's the beauty of blogging where absolutely no one is making any damn money from the entire enterprise: I can just spin out a fake word with 30 or so hyphens and just move on.

OK ... I was reprimanded once for using the kind of language that flows continuously through my favorite podcast, and I considered just chucking the whole blogging-for-the-man thing and doing this on my own time, on my own site and enjoying the tens of dollars yearly I could earn from Google AdSense.

OK, I pretty much do this entirely on my own time as is ...

Anyhow, I'm ready to return to the raw meat of this blog post, which is my trouble with wireless networking.

So I did the hard reset, booted back into Ubuntu and while things seem a bit slow, networking-wise (that could be anything), it's working OK for the moment.

Here's what I'm thinking:

The problem might not be the specific wireless networking adapter; it could be an issue with USB (1.1 in the case of this old hunk of saved-from-the-garbage hardware). Whether Linux-related or not, perhaps the Toshiba just can't handle using the USB inteface that intensely.

I don't recall having any problems with the PCMCIA adapter I use with every damn PCMCIA-equipped computer known to woman and man, namely the Orinoco WaveLAN Silver (all I'm saying is if you don't have one of these, go to eBay and get one; for me's it's the geek-networking equivalent of the Swiss Army knife or Leatherman.

So a "newer" Cardbus adapter (maybe another $10 Airlink?) might work better for this particular laptop.

Another thing: If whatever problem I'm having is related to software, it's possible that performance will improve and crashes will diminish (or end entirely) with newer versions of everything from the Linux kernel (remember, I'm using Ubuntu 8.04, which is pretty much a year and a half old; ancient in Linux terms) to the dreaded NetworkManager in GNOME or anything else in the stack.

But given my recent experience, I'm extremely gunshy and more worried about regressions than either a lack or abundance of "improvements." That's what screwing up Xorg for probably half the PCs out there will do to you, O Xorg developers who decided that working Intel video is for other people, meaning people who don't have Intel video chips embedded in their PCs.

Can you tell I'm bitter? I thought you could.

Of course with the super-fast USB 3 on the horizon for Linux — yep, first for Linux and then for the other 99 percent of the world, I expect we'll be getting more USB-connected hardware and not less, and that includes add-on network adapters, which I suspect will be with us in various forms for quite awhile as PCs' built-in networking (wired and wireless) are superseded by newer devices and protocols.

I'll continue testing the Airlink 101 AWLL3028 USB adapter and even consider entering the modern era and slapping Ubuntu 9.10 on this laptop. I'll try an in-place upgrade from 8.04-8.10-9.04-9.10, and if that doesn't work I can do a reintall with a fresh 9.10. That'll keep me (and my office's ample bandwidth) busy for awhile, I suspect.

I'm always hopeful; "It's only one crash," I say to myself. But one crash usually begets many more. I say usually hoping for the unusual and simultaneously wondering to myself why things have to be this hard (and remembering that these kind of problems reared themselves very well during my time running Windows 98/2000/XP and Mac OS 7.6/9.x/10.x).

Right now with the built-in wired networking, this hardware/software setup is pretty much problem-free (OK ... suspend/resume is a disaster, but I wasn't expecting anything more with hardware of this now-7-year-old vintage).

It's a good time to put my optimism hat atop my head, leave the friendly confines of the Ubuntu LTS behind and leap into the world of the six-month upgrade cycle and hope that improvements drown out regressions.

After all, I can always initiate my own regression and return to 8.04 (or chuck it all for something safe like Slackware 12.2 ...). I called Slackware "safe." Time for more coffee.
