problem with wireless Ethernet on HP/Compaq Presario CQ61-420US


Greetings. I am presently experiencing a problen in not being able to use my new Compaq CQ61 laptop's wireless communications circuitry. I found a posting from a year ago at http://ubuntuforums.org/showthread.php?p=7717667 that describes the problem with another model of the CQ61 and gives a solution, which involves installing a package called "linux-backports-modules-jaunty," which I can't find, and probably doesn't apply to newer versions of Ubuntu Linux anyway. I can't get wireless to work under Ubuntu 1.04, Mint9 and Debian 5.04 (all 64 bit versions), but it works fine under Knoppix and Win7, so I know it's not a simple hardware issue.

I'm wondering whether finding a more recent version of this package could be expected to fix the problem also, or if "all bets are off" at this point. I did find something called "linux-backports-modules-wireless-2.6.32-24-generic," but it fails to install, apparently due dpkg not liking the downloaded module (see http://pastebin.ca/1943245 for the details of what happens when I try doing that installation).

Has anyone heard of this problem, and/or does someone maybe have any suggestions for approaching it?

Thanks much in advance!

more information regarding my recent problem report

[ Thanks to TobiSGD for alerting me to the fact that I had the wireless device turned off when I ran a few commands to produce an earlier version of what's shown below. I have now turned it on, re-run those commands and edited my original posting accordingly. It took me a few tries to get things right, so apologies if you saw an earlier incomplete rendition. ]

Further to my original posting, I have just found a thread in the "Linux - Newbie" forum at http://tinyurl.com/3yq4cwg in which senior member schneidz says (07-23-10, 10:01 AM) that it's useful to provide information obtained from looking at a few files and running several commands. Here are my answers to those questions...

"iwconfig" produces:

"lsmod" gives a bunch of output. But since I don't know which bit is relevant for our purposes, I'll omit it for now.

I hope this info helps. Please let me know if there is anything else I can do to provide more details and/or point me to sources of what might be useful in the way of background reading.

Thanks much!

There is no wireless device found in the output of lspci and lsusb. Is there a switch to turn wireless off?

Ah - silly me! Indeed there is. I've just turned on the device and the wireless feature of my router and re-run the commands above. I amended my posting accordingly.

BTW, I have mixed feelings about wireless routers and mobile phones and have collected a fair bit of information about the dangers of both. The latest discovery I've made comes in the form of an interesting short news documentary (about ten minutes) played recently on the Canadian Broadcasting Corporation's "The National" nightly TV news program. It talks about children being especially vulnerable to the radiation emitted by wireless routers and looks at a couple of cases of children becoming ill at school (headaches, nausea and other symptoms).

The video report is at http://cbc.ca/thenational/blog/2010/...e-worried.html .

more info: output from "mintwifi" command

Hello again. I just discovered a Linux Mint forum (I'm running Mint9) and have posted a slightly amended version of what I posted here yesterday to http://forums.linuxmint.com/viewtopi...320724#p320724 . I added some info to the post, based on a rule there that something called "mintwifi," which probes the device and provides more info, must be run before posting. I'm supplying that info below, in case anyone here would find it helpful.

If I get an answer in that forum, I'll post it here, and vice-versa.

Thanks again!

"mintwifi" produces (run with wifi enabled, but with an Ethernet
cable plugged into my router and wifi turned off on the router,
though it was enabled):

lo no wireless extensions.

eth0 no wireless extensions.

How the problem was solved

The problem is now solved, thanks to the assistance of Marco Braida, who replied to a copy of this posting I placed in an Ubuntu forum:

https://answers.launchpad.net/ubuntu/+question/126770/

Please see that forum for a description of the procedure I followed, which Marco suggested. Just after the problem was solved, another mostly-unrelated one emerged, which is described toward the end of the thread. However that issue was ancillary to my main problem, though it was quite vexing while it lasted.
