    Wireless connect w/12.04 on AspireOne D-250

    Hi, I know just enough to SNAFU things. I upgraded from 11,04 to 12.04. I have wired connection. Without I do not. This issue was happening on 11.04 also. I keep getting a dialog box asking for my security password. It accepts it (or seems to) then if i open a browser window I receive "can't find server" and security dialog box for my connection comes back up.

    I've nosed around here as much as i can and found that:
    "sudo Ishw -C network" did nothing for me, "command not found", not that I actually knew what I was typing.

    Then I tried "lspci". I've pasted the result below. I'm hoping this is helpful. Any help is appreciated. Thank you 8lackie

    Re: Wireless connect w/12.04 on AspireOne D-250

    I have 5 Acer Aspite One laptop in different sites, all with Ubuntu 12.04 and have seen a similar issue when the wireless connection has problems and sometimes repeatedly asks for the password.

    After researching and trying a few things, I found that:
    1. The Aspire One wireless reception is not as good as a full size laptop. As a result it is much more sensitive to bad reception issues.

    2. It has an issue with a combined cipher of AES & Tkip or just AES. It works well when I use Tkip only (this is a setting in the wireless router, under the wireless settings).

    3. If you have a wireless range extender, sometimes those lose connection while the Aspire One connection is to the extender. That will kill your laptop's connection (you can avoid that by setting up on the laptop's network settings the BSSID to be that of the router you want to connect to always).


    So to test these assumptions, I suggest the following:

    1. Change in the wireless the cipher to be only Tkip.

    2. Remove the wireless password on the router and confirm that the Aspire One can connect to the WiFi. Make sure the laptop is close enough to the router so you can rule out reception issues

    3. Add the password back on the wireless router without moving the laptop away, and see if it connects now.

    if no good connection is made, you may have a different problem. Try to upgrade the router's firmware to the latest.

    If good connection is made, just continue to make sure you have good reception always.

    Hope that helps!

    Re: Wireless connect w/12.04 on AspireOne D-250

    Thanks for your help OM55. I'm bivouacked in the Balkans at the moment. My internet is a cablebox/wireless router in-one. I cant seem to get into it via 192.168...etc so for the time being I can't see what the setting are or mess with them.

    No wireless range extender.

    I've been sitting next to the router the whole time. I did have Ubuntu 10.04 on here once upon a time and it worked fine. Of course the question is "what changed?" I don't know.

    I found the 802.11 Linux STA driver. but don't know if this is already part of 12.04 nor do I understand how to install it, or if would be any benefit.

    I also tried "sudo apt-get install firmware-b43-installer" This seemed to be already installed.

    At least I have a good wired connection. I am stuck.

    Please avoid overusing coloured text. If you want to make code stand out and easier to read, please use [code] tags by typing them in or clicking 'Edit' then 'Go Advanced', mark out the code and click the # icon. Cheers.

    Tried any of these?

    If you can find an ethernet connection you might try looking at the following thread--post 10.

    Re: Wireless connect w/12.04 on AspireOne D-250

    I dont know if this will help, but I read hundreds of posts and tried lots of fixes without success- usb detected but no wlan. I finally downloaded the 12.04 precise image and did a clean install - the package has all the drivers to find the usb devices. The wifi airlink 101 usb - compaq was immediately recognized and connected. The upgrade from 10.4 to 12.04 left something behind.

    I did have to perform sudo shutdown now -P once after the install to get the shutdown button to work. goog luck.

    Thanks guys for responding. I'm sorry to be a pain in the butt.

    I get:
    blackie@sherpa:~$ lsmod | grep -e b43 -e wl
    wl
    2646601 0
    lib80211 14040 2 lib80211_crypt_tkip,wl
    blackie@sherpa:~$


    I'm not sure what this actually says....but took a chance it says wl is loaded so I ran dmesg | grep -e wlan -e eth1 -e wl
    and I get:

    blackie@sherpa:~$ lsmod | grep -e b43 -e wl
    wl 2646601 0
    lib80211 14040 2 lib80211_crypt_tkip,wl

    blackie@sherpa:~$

    What should be the next step?

    You now have a wireless interface eth1. Does it scan?
    Code:
    sudo iwlist eth1 scan
    Is the switch set correctly?
    Code:
    rfkill list all
    If you are not hard- or soft-blocked and it sees networks, you ought to see networks when you click the Network Manager icon.

    Re: Wireless connect w/12.04 on AspireOne D-250

    This is what I get.
    Yes I do see networks. But then I always have. Yet I still get "authentication required" over and over but no connection. Frustrating!
