wireless net not connected


i have knoppix on a live cd, and basically this is the problem, i have a belkin wireless lan monitor that gets a signal from my router downstairs, in linux it wont let me connect to the internet and ive tried random things in the networking section which looked promising and turned out useless, it says one ethernet adapter, (eth0), is connected but its not letting me on, i trust there is a simple solution, help me out and thanks

We're going to need to know a bit more about the wireless card you're using, specifically the chipset. If you don't know what chipset it is try running lspci and see if it is listed. Also if you post the outputs of ifconfig and iwconfig it could help figure out what is going on. I'm going to assume that Knoppix hasn't picked up your wireless card, but maybe it has (and by the way, the Knoppix version your on would help too).

Yeah eth0 is not the correct connection eth* refers typically to an ethernet connection.

Wireless networks are normally wlan*. Hopes this helps.

Not necessarily. At least on my rig, the device naming is driver dependent. When I run my Broadcom4306 card under ndiswrapper, it is wlan0. When I run the exact same card using the bcm43xx, it shows up as eth1. Also, Atheros based cards tend to show up as ath*, and I've seen Ralink cards as ra*.

Basically, since ndiswrapper is so widely used, people tend to think all wireless cards are wlan*, but it in reality, there is no convention.

Hangdog,

Completely unrelated to the post, I just want to say that your quote is hysterical. It may just seem that way because I'm tired and sick. Funny nonetheless.

Regards,

Brandon

I may be having an off day, but what you just described makes no sense to me. You have to have some sort of wireless card/device/thingy and I'm assuming that the Belkin is it. What is its make/model number? When it is plugged in, try running lsusb (as root) and posting the results. And as I asked in my first post, could you post the output of ifconfig and iwconfig? As it is we're not going to be able to help without more information.

That quote is from my all time favorite Far Side cartoon. Man I miss that strip.

to the original poster,

when you say you have a 'usb thing' in your computer, does that mean that you have a USB-INTERFACE WIRELESS ANTENNA ?

If yes, then what you're actually talking about is a wireless (wifi) 'card' or 'interface' or whatever you want to call it that is built into a tiny little thing that is the same size as a USB-flash-drive (memory stick, removeable drive, whatever you want to call it).

These are a common type of wireless interface, but they have a few issues:
1- they tend to suck (just being honest).
2- there are little if no driver support for these under linux.

PCI card or PCMCIA card wireless interfaces from Realtek, Atheros (some Belkin, lots of D-Link, some Linksys, At&t, others), and Broadcom have third party drivers built for them from guys like madwifi.org.

However, with a USB-key-style interface, I'd say you're shit out of luck.

I reccomend hunting down something with an Atheros 5212 chipset. Madwifi drivers work great with that.

i dont think were communicating properly, i have an antenna as said previous, its called a "Belkin WLAN USB monitor" its an antenna with a box attached to it with a cord leading to a usb plug going into my usb slot, linux should detect it, but it isnt, im doubting theres a linux driver on their site, and even if i had it its a live cd id have to point it in the right direction every time i boot up, there should and probably is an easier way to do this, as in, i click on a configuration program under knoppix, fill in some ips and gateways and i should be on my way

What poweredbydodge wrote above is true. There is very little (if any) support for usb wifi in linux.

The problem isn't that you have bad IP info (address, subnet, gateway), that would all be handled by the wireless router that you have downstairs. The problem is knoppix can't reach the router downstairs, as there is little to no support for usb wireless cards. Yes, what you have is a wireless card, just with a USB interface rather than the more standard PCI interface.

In short, you're probably SOL unless you run a ethernet cable down to your router, or install a PCI style wireless card that has some form of linux support, either natively through the kernel, or by bastardizing the windows driver with the help of ndiswrapper.

Peace,
JimBass
