Channel 14 Issue - Please Help


Hi,

I'm new to Linux so please be gentle.

I recently installed DD-WRT on my brother's router and while playing around with the settings foolishly set it to channel 14 and now can't access the router anymore. I also don't have access to the physical router for a week as he is away.

I'm trying to get a Linux distro setup so that I can connect back to the

router that is still on channel 14 and set it back to a channel that I can easily access. I've had no luck with Windows and I've made some headway with Backtrack in having my computer (Thinkpad R61 w/Intel
3945 a/b/g wireless) at least see the network as it does not under Windows.

I did this with the following commands in the Console (in backtrack 3) that I found in a forum:

airdriver-ng unload 16
lsmod #confirm driver is gone
modprobe ath_pci countrycode=392
airmon-ng stop ath0
airmon-ng start wifi0 14
iwconfig #confirm Frequency:2.467 GHz

airodump-ng -c 14 wifi0
iwconfig #Use another console session and confirmed the freq and channel 14

But now I'm stuck as I can use my computer to see the network in monitor mode but I don't know how to actually connect to the network to access 192.168.1.1 in ddwrt to change the channel. I also have access to a desktop that has a netgear wg311t card with an atheros chipset if that would help at all.

Any help that anyone can provide is greatly appreciated!

Thank you,
David

You are certainly wrong starting with Backtrack at this point.

Choose a more user friendly one, if you don't want to install it, choose a live distribution. There are many http://distrowatch.com

Seems you have no idea what you are doing, these are NOT the tools to connect to a router/AP.

Use wicd or whatever to discover the network and connect to it, and since it's your brothers network I'm sure you have the permission and the respective keys to access his router/network while he's away. If not, wait for him to come home and reset this box.

You are correct that I don't know what I'm doing in Linux. That's why I'm asking for help. I tried ubuntu and gOS first but the drivers for my wifi card in those don't seem to let me see channel 14 and found those commands online for backtrack so I used them.

Yes, I do have access to the network but I can't access it and thus have no Internet access at home and am dying without it .

If I use wicd will it let me see channel 14?

Thanks David

Try it out, it depends on your driver.

Code:
wicd
starts the server

Code:
wicd-client
starts the client (it will discover the networks available around) where you can also do adjustments such as IP, key and so on. Don't know if it is available in BT3, but it is in BT4.

I tried it and channel 14 didn't work with wicd. I'm under the assumption that I have to use the console to adjust the driver to see channel 14. Any thoughts?

Thanks
David
