Questions[ath5k](ubuntu)

I have a Samsung N210 and just installed Ubuntu. I'm new to Linux and I have some problems.

I'm using Linksys WRT110 Router. When I'm connected via ethernet cable everything's fine but when I unplug the cable and try to use wireless it's really problematic. The connection is unstable. I can use the internet for 5 minutes and then for a couple minutes it's gone and it comes back again and so on. But the thing is, it always shows that it's connected, but I can't connect to any websites. As I said, no problems with ethernet cable.

I made some research, installed Samsung-tools (and then came here to ask) and Realtek 8192E wireless driver for the latest kernel for Samsung netbooks with no luck. Also I uninstalled Network Manager and installed wicd, that didn't work either. What may be the problem?

Here is the output of the lspci command:

Thanks in advance for all the suggestions.

P.S.: When I open System > About Ubuntu, it says "You are using Ubuntu 11.04 - the Natty Narwhal - released in April 2011 and supported until October 2012." Why does it say 11.04? And April 2011, huh?

I sometimes connect to a defective wireless AP in my office, whose 802.11n is somehow faulty. My Maverick netbook has an atheros AR9285 wireless, which supports 802.11n and wants to connect the AP with 802.11n, failing.

I managed to fix the thing in Windows by disabling the 802.11n mode and enabling only 802.11b/g. Is there a way to do the same in Maverick?

I have been struggling hard since i have installed Ubuntu 10.10 but it has been difficult for me to get my wifi working.

So here is what i tried.

• First i checked whether i have the driver using the ifconfig command and it shows the wireless lan driver as wlan0.

• Next, i tried the command iwlist wlan0 scanning by becoming the root which gave me the output as no scan results.

• Next, i visited this link https://help.ubuntu.com/community/WifiDocs/Driver/Atheros to see as to what problem my laptop may have. I do own have an ath5k chipset. And as i followed the instructions in the above link in one of the blacklist-ath_pci.conf file had this written in it.

For some Atheros 5K RF MACs, the madwifi driver loads buts fails to correctly initialize the hardware, leaving it in a state from which ath5k cannot recover. To prevent this condition, stop madwifi from loading by default. Use Jockey to select one driver or the other. (Ubuntu: #315056, #323830

I am not that good at Linux but i have given it a try. I am desperate to have my wifi working and i would be glad if this community could help.

• ADDED: If anyone would like to know as to what drivers i am using this is the output.

How can I install atheros drivers to my Toshiba laptop (64bit), manually?

I need AR9285 wireless adapter, and AR8152(v1.1) wired, fast ethernet.

I cannot connect my UberStudent1.0 (linux OS, Ubuntu10.04,equiv.) to the net. I have on the laptop Mint8 which connects well and able to download any drivers. Please, would you kindly show me how to install them if they are not .deb formats. Tarballs, zip,etc, still give me a hard time to work with.

I've recently bought a Toshiba Satellite C655. It came with Windows 7 preinstalled. I've never had a notebook before, but as a desktop user, I was a Ubuntu user since 2 years, and I've never had a problem with drivers, wifi, etc.

When I tried to install the Ubuntu 10.04, and also the new and fresh 10.10, in my new laptop, I experienced some troubles with some of the componentes of my computer. For example, I was not able to activate my wi-fi card, although I know the kernel recognizes it correctly, because when doing "lspci" at the terminal, it was listed.

Anyhow, I'm not able to "activate" the wifi, or whatever it's necessary to do in order to be able to search for public networks available, and to connect with them.

The wifi-card the laptops brings is the (the lspci output):

03:00.0 Network Controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) [168c:002b] (rev 01).

It's anything in you can help me? Thanks a lot in advance!

Edit

Neither solution seems to work. In first place, i've tried installig what hhlp told me. After the installation, nothing seems to change: on right-clicking the wireless icon, it seems to recognize the card, because the option "Enable wifi" was ticked. But, once again, i was not able to "turn the wi-fi" on.

In second place, i didn't try installing the drives, because the card is already recongnized. The issue is that i cannot seem to turn it on!

One thing i've probably missed is that the Toshiba cames with a windows sofntware that allows you to enable / disable the wifi tools. So, it does not have an external "button" to turn it off. I don't know if that's the problem, but i have the feeling that the issue may be aroud there: in how to turn ON the wifi-signal (or to verify if it's on or off) in my ubuntu.
