internet via cable yes - via w-lan no

[london]

Hi,
my first day with kubuntu 9.10, solo running on a Sony Vaio VGN-A517B notbook.
I read in the forum to run "ifconfig". What happens? nothing, nothing apears.

So I have perfect internet acccess via the cable.

Using W-Lan, the configuration is:
SSID: ruter is seen by "scan", correct name is given
Mode: infrasructure
BSSID: is correct
Restrict to interface: any
MTU: automatic
Security: WPA/WPA2 Personal
Password: = BSSID
IP Adress/Configure: Automatic DHCP

What is wrong

Thank you very much!

What model exactly is your card? lspci or lsudb will probably give it

Are these notes you've typed, or is the above the output of some program? And how should we interpret the second-to-last line? It could mean either of:

• You're using the actual five-character string "BSSID" as your password -- which would be pretty weak
• You've entered the BSSID (usually the MAC address) of your access point as your password

I tried hard to find out, but no way to find model of the W-Lan card. Nor via my documents neither via internet.

So it could be, that it is a hardware problem and so no chance at all to get it running?

Hi,

these notes are typed by myself.
I use a 9 letter/number password.

@jpenguin asked you to run "lspci" to find out the model of the wireless device ........open a terminal and type in lspci and press enter ,,,,look for the "network controller" line ,,,,,like this

There more likely than not is a driver for whatever card you're using, i don't use wifi on my desktop- and my laptop was built for Ubuntu

That's why adding the -k switch to lspci helps; it shows in-use drivers:

steve@t520:~$ [B]lspci -k[/B]
...
00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit Network Connection (rev 04)
        Subsystem: Lenovo Device 21ce
        Kernel driver in use: e1000e

...

But lshw can be even more informative (run elevated):

steve@t520:~$ [B]sudo lshw -C network[/B]

What this information, it helps us make better suggestions for fixing problems.

I tried every trick on every forum for my wireless cable network/driver issues. Many hours later =frustration! Tried many different Linux systems. In the end it was the 32bit systems that worked for me. Tried every popular 64bit Linux based system some would connect poorly others not at all. So if you can handle going 32bit it might work for you too but expect problems with internet banking and email logins. I think I'll go back to wired for my laptop once I get the cable relocated to my living room.

[claydoh]

I can't normally recommend installing 32 bit versions on 64 bit ready systems. 32 bit support seems to be on its way to becoming secondary as most of the eyeballs are on 64 bit.

Without knowing your hardware specs and possible real solutions for for your system's WiFi problem, I would have to say that you have a very rare, edge case here.

I agree with Claydoh. A kernel upgrade during the summer rendered my wifi connection inoperable so I resorted to a cable connection as well. It was easy for me because my wifi router is only three feet from this laptop. I decided to try other kernels. The 3.11.8 kernel allowed the AR9462 chip to work again, and work well. It now gives me a reliable 150-300 Mb/s connection. My eth0 connection is only 100Mb/s. It gives me a 15.1MB/s dl test but the wifi gives me 15.5MB/s dl.
