    No, a *.iso is an image of the ISO9660 filesystem ... in other words it's like having a disc in a file. You need to "extract" the file onto the CD, several burning tools can do it automatically -- I recommend ImgBurn (free)

    You can save things on most live distros these days without needing to write to the hard drive. Most distros provide a "persistence" mode that uses a usb pen. Takes a little setting up, but once it's done it's rather seamless.

    I tried Ubuntu after I saw near 100 unresolved WLAN questions in knoppix's forums. I can now get on the internet with ethernet but still missing drivers for WLAN.

    Unfortunately, in the case of many WLAN chip producers do not publish specifications for their chips (so it's very hard to write a driver for those chips), and the company that makes the chip does not produce Linux drivers. There is a "Windows compatible" driver shim - this means you can use a well-behaved Windows driver in Linux. But I'm not clear on all the details of it.

    Are there any linux distros that provide any wireless support at all?

    For WLAN? matsp wasn't speaking in just the case of Ubuntu but Linux in general.

    Yes, but make sure you tell the chip manufacturers, not the Linux developers - it's the formers fault, not the latter. It's hard work to write drivers for a chip you KNOW how it works - it's near impossible to do for a chip where you don't have any instructions on how the chip actually works.

    The average network chip has some 50-100 registers, most of which have more than two fields in them (of varying width, say bits 0..3 represent something, bits 4..15 some other thing, and bits 16..32 another thing). So there may be some 3-400 different values that need to be in the correct state at any given time. Obviously, figuring out what 300 odd registers do without a manual is like trying to solve a jigsaw puzzle with hundreds of pieces with no pattern to identify which goes where.

    Most of them just need to be set up the once (to match the OS's view of things with the chips view of the world, and to match up with the actual hardware design), but some need to be reprogrammed when:
    - a data packet has been received.
    - a data packet has been sent.
    - there is an error in receiving data.
    - it didn't work to send the data.
    - many other more or less common situations.

    Wireless chips are further complicated by having a radio and encryption units that also have a few registers each.

    There is some useful (at least I think so - I have never actually set up a WLAN chip on Linux) info here:

    Of course I understand it's the chip manufacturers and not Linux's fault. I am just going to dual boot with windows whenever I need WLAN. Also, what is the latter? Iv'e heard the term a few times and now im really curious.

    Former and latter are references to the first and last of something mentioned before. For example (sentence made up as I go along ...):
    C is a programming language, so is C++. The former (meaning C) has no direct support for object oirientation, where the latter (meaning C++) has classes to help in an object oriented design.

    I have a number of Linux boxes that use wireless. I either use a wireless card with a native driver (anything Intel seems to work fine and if you need to buy one look for the edimax brand - that uses chipsets with good linux support) or use ndiswrapper with the windows driver.

    Either way, you need to understand that things arent as easy to setup under linux as with windows (mainly due to poor support from hardware vendors) so you are going to have to spend time googling problems, reading tutorials and generally fiddling with stuff until it works.
