Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Ralink RT5390 spotty WiFi performance on any kernel past 3.2.x series
I know this should be posted in the hardware forums (maybe). But I think the Slackware community is the most knowledgeable and most likely to provide help in this case. Also, I am running Slackware. :-)
If I'm running Slackware -current with the 3.8.13 (smp) kernel, my WiFi performance is spotty (my laptop is an HP DV6.6135dx, for reference sake). This isn't distro specific, I have spotty performance on any other distro, and any kernel greater than 3.2.x. I'm not sure what changed from 3.2.x to current kernels in wireless modules but my WiFi cuts out a lot, or is slow (and using wicd, networkmanager, netcfg, netctl or even just pure wpa_supplicant does not help).
I have already tried:
- Disabling 'N' speeds on router
- Compiling driver from Ralink's website (it causes a kernel panic)
AFAIC, you won't get it any better than it is. Wifi just isn't quite 'there' yet in Linux, IMO. I was having the same troubles as you, with two different routers from two different companies and still had the trouble and wicd and networkmanager.
We just need more people to get in on the wifi thing with linux, like engineers and such, to help get it where it needs to be. Until then, I suggest going back to wired - it's fast, steady, reliable and 'just works'.
Meh...it happens, I suppose. I saw it with the module build for older Philips webcams when the kernel people suddenly said they didn't want it to be able to tap in, so for a long time us Philips owners got the shaft, then suddenly it's 'built in' in the kernel but doesn't work nearly as well as the old way of installing it and using it did, so I have a perfectly good (even if it is 'old' it's *still* got a better picture than most of the 'new' webcam pics I've seen) webcam gathering dust.
Hopefully word will get out about the newer kernels not working as well as older ones with wifi and things will 'get fixed'. Can't never tell though.
For drivers that use the rt2800lib module someone messed around with the tx power. It causes the rt2800pci (and probably other) drivers to revert to the bandwidth of smoke signals on a cloudy day. The patch here fixes it:
