I have an issue with my on-board wireless card (powers down after about 5 minutes) so I'm stuck with a USB card. I don't use the on-board card and it causes the system to intermittently hang if it's powered on (once I run ifconfig wlan0 down, the system runs fine). Is there a way to power down the interface (or better yet prevent it from powering on) at boot?
View 4 RepliesI recently bought a new nettop and installed Ubuntu 10.10 Desktop. Unfortunately the on-board wlan is kind of crap so I bought a USB Wireless stick and since that stick has a pretty recent chipset ndis was needed to get the USB stick to work as wlan1.
The issue is I want to disable the on-board wlan (wlan0). The BIOS does not offer that option so it needs to be done in the OS I guess. My question is what is the best way of doing so? I've read something about blacklisting or editing 10-wlan.rules but I am unsure what the best place is and what to put there.
This the output of ifconfig:

Heres the set up I have: one eeepc running ubuntu netbook. with a usb wifi dongle, this is connected to a parabolic antenna i made out of pizza boxes and tin foil. One fujitsu laptop running ubuntu 10.10. the eee connects to the internet via the dongle. then the laptop connects to the eee. I set this up by using network manager. I created a new wirless connection and called it "UbuntuAdhoc". The on-board card connected to this without issue and the laptop was able to connect to the new wireless broadcast by the eees on-board card.
This worked perfectly untill I rebooted the eee. Now the eee is unable to conect to the internet if the on-board caard is conected to "ubuntuadhoc". also the dongle now wants to conect to "ubuntuadhock" too.
I've had a host of problems since upgrading to 11.04 Natty Narwhal, so let's deal with these 1 at a time.
I've got a Hewlett-Packard Pavilion G60 laptop. Next to the power button is a handy wireless on/off button. This has always worked well with previous editions (9.04,through 10.10). first press toggles the wireless off, second press toggles it on.
Not so in 11.04. The toggle off works great, first time. But, it will not toggle back on. Not after any number of tries, not after restarting, not after booting into other OS's (9.10 and Vista) re-enabling it there and then booting back into Narwhal. to further complicate the issue, this feature bypass the network manager, so toggling the wireless off by the switch leaves me showing no wireless adapter in the network manager. I also restarted, switched from Unity to a Gnome session, but the issue still persists.
As my only network options are wireless, this has become a substantial inconvenience.
----
EDIT: so the network util is actually saying "wireless disabled by hardware switch". Also noticed it I enable it in 9.10, reboot to 11.04 (where I inevitably fail to re-enable it), then reboot into 9.10, it will initially be disabled. The key difference is in 9.10 I have the ability to enable wifi using the hardware button. It seems that 11.04 is remembering that wireless is disabled between boots. Is there a place it might be storing this value? If so, I may be able simply to set the value as enabled, since toggling that silly button isn't working.

EDIT 2:
found this thread:"Wireless disabled by hardware switch" bug? - Natty
seems to be a similar issue. I'll be following how that one develops, too.
My wireless can connect to my router without a problem, but in order to do so (after boot) I must first disable networking in the Notification Area and then re-enable it. I don't mind it too much, but when other people use my computer, it's made painfully obvious to me, that this was never an issue with Windows 7 (as much as I despise MS).
View 9 Replies View RelatedI don't use wireless on my desktop so i would like it permanently disabled...each time i boot up it's back and receving up to 80mb of data from an unknown connection via wireless (i dont use wireless) so, to avoid any weird connections to my neighboors house or some kid hacking the neighborhood driving by with a wireless router in his truck i'd like to permanently turn off wireless. this is kind of funny because i had a hard time getting wireless to work on my laptop, but this is my desktop where i do not want it. i looked it up and your forum back in 2007 said to type in iwconfig in the shell then get the nickname of the wireless card then to black list the wireless card. i did this but it didn't work, so what do i do now? i have ubuntu 9.10
View 9 Replies View RelatedI use this Thinkpad mostly for work while traveling, and wireless connectivity is not a big issue for me. Battery life is a big issue, however. I've just converted from Mandriva. With that, I was able to disable the wireless adapter so that it did nothing at all on boot - and only started on my instruction. This made a dramatic difference to battery life! How to achieve this in Ubuntu? The file attached gives all the info about my wireless set-up as it stands.

I am doing some experiments comparing the performance of wireless under 3 different cases:
(i) without media sensing (carrier sensing).
(ii) with media sensing but no RTS/CTS
(iii) with media sensing and RTS/CTS
I know RTS/CTS can be controlled by iwconfig interface rts {N|auto|fixed|off}
However, what about media sensing? Can it be disabled? If yes, how?
My Intel 5100 AGN adapter works horribly in Ubuntu. I want to disable it, so I can use a USB wireless adapter that works normally.
I cannot find a reliable way to permanently do this.
11.04 64 bit I just picked up a new high-gain usb wireless adapter that I would like to use for a while in place of the built in wireless adapter in my desktop. It is detected and works just fine. My question is this: Is there any way I can disable just the built in adapter and leave the new one active (or visa versa?) I don't want to remove the built-in one as there will be occasions that I will want to use both.

View 2 Replies View RelatedI have a strange problem with my networking under Ubuntu. When I first log in to Gnome both my network adapters are listed as "disconnected" in the network manager applet. If I right click on the notification icon and disable networking, then wait a few seconds and re enable it, it works fine.
It's happening consistently with Maverick although it seemed only temperamental with Lucid. I did a fresh Maverick install to see if it would help but it hasn't.
It's the onboard network sockets on a Gigabyte GA-X58A-UD7. I have two ports but I only use one, it doesn't seem to matter which I use. It's connected via gigabit ethernet to a Netgear router. It works fine in Windows 7 (dual boot).
It looks as though something's not quite "ready" when gnome first launches. The light on the router for the cable is off at first, and only comes on after a few seconds. It's DHCP. Same thing happened on the live USB stick (just before the isntaller) and disable/reenable made it work.
Anyone know of a mother board with an onboard wireless nic that works with linux?
