Ok, so here goes. I have an Emachines D725 laptop and Ubuntu 11.04 installed on it. I was pretty much happy to be trying Ubuntu ... installed it ... rebooted and then logged on. However, when I tried to access the internet, it wouldn't connect. Worse, I couldn't see my list of wireless networks. I tried connecting through my Windows OS; it worked. However, it won't in Ubuntu.

I read this thread http://ubuntuforums.org/showthread.php?p=6183681 and followed all the instructions, and now I would be putting the link to all the results of these commands. Pardon my lengthy explanation; I just want to clarify things. And I REALLY want to be able to use Ubuntu. Hope anyone can help. I KNOW you guys CAN help. :)

OK, here it is:

(1) Machine Brand and Model
Emachines D725-432G32Mi
Model No. MS2268

(2) Wireless Brand Model and Chipset

If anyone can explain the steps I need to do to start connecting to my wireless network, I'd very much appreciate it. Thank you.:popcorn:

Sorry for the late post. Just got home from school. And switching from Windows Xp to Ubuntu takes a ridiculous amount of time.

Anyways, here are the results:

This will be just temporary until the next boot, but try

sudo rmmod -f acer_wmi

and then run the rfkill list all again and see if the block is removed.
(Try your wireless again!!) If it does work we will make it permanent.

I did what you told me to do and it displayed this result:

Hi, it is no longer blocked, so make sure you have wireless enabled by clicking on the internet icon in the top right corner of the screen and unplug your wired connection then restart your system and see if it will connect.

Please if we need to run more commands please post the results here not in a link, I need to see them all on the page so I can refer back to them easily and when I tried to view them at the link it was small text and it was hard to read and when I clicked for full screen they started playing a slide show changing every few seconds.
Thank you

WOW those pictures make it difficult huh? Nice catch bkratz..

My eyesight is not good enough for more..viewing

I had a heck of a time--used the zoom function of Chrome to see them, but they became really fuzzy. Just good luck I guess!

I think the name you are looking for is in the stickies first post



Solution 1: System > Administration > Synaptic Package Manager > Search: firmware-b43-lpphy-installer > Click Mark > Click install > Close

Just wanted to say THANK YOU SO MUCH WILDMANNE!! You even don't know how many hair-pulling #-oand nerve-wracking ](*,)](*,)](*,) hours you saved me. I can now access the internet, and right now I'm updating some files through the Update Manager.


Oh yeah, I'll mark this post as SOLVED. I'm totally addicted now to Ubuntu. Keep up the good work, and thanks again. Kudos! :lolflag:
