Um, linux isn't really that bad with wifi as people seem to think. All
you need is a good chipset. ANYTHING RALINK WILL DO. Why? because they
have provided the source for their drivers to the linux community and
now there are good high quality drivers native to linux, no ndiswrapper,
no windows drivers, just a straight up kernel module code which you
download from rt2500 at sourceforge and compile from source, so you know
it will work on your system no matter what.
The Source code even comes with a GUI wireless configuration and signal
monitoring utility - it's as easy to configure as if you're using
windows XP. There are Ralink chips all over the place on wireless usb
adaptors, PCI cards, you name it. Ever heard of them? No? Of course
not because you didn't do and RESEARCH before trying your wifi network.
Let me ask you this then. If wifi is so bad and has so many
disadvantages, why did you even try to use it as your first choice??
I'm using wifi in my mythtv box with a ralink2500 chipset, and have been
happily ever since I built my myth box. I get a constant 54MBps with
the router a few rooms away. In fact, I never had a single problem at
all anywhere along the whole process, which took me 4 minutes to compile
the driver and then install the kernel module. It was the easiest thing
in the system.
Here are a couple more pointers for you. Everyone in the neighborhood
can see your computers huh? Ever heard of Mac address filtering and WEP
or WPA encryption? Your signal is too low? Did you EVER even consider
getting an external antenna that connects to the SMA connector on your
wireless card? Put a $10-$20 antenna on your wireless and then put the
same on your wireless router. Don't get signal on floor 1? Put one
router on floor 2 and measure signal on floor 3 and 1, put another
router as a repeater on the floor with the weakest signal.
For Christ's sake, I am absolutely amazed that you even got your mythtv
box up and running at all, someone who can't even do some simple
research and install a simple wireless network.
I think all the howto guys like Jared Wilson need a big round of
applause because this means that the howtos are getting GOOD.
By the way I hate it when people send out emails with all caps subjects
telling the whole world to shun an entire industry because that person
was too inept to partake in it. You probably noticed.
