WiFi issue in Ubuntu 10.10

[binilbenjamin]

Hi.

I'm facing a strange problem after upgrading my Ubuntu to 10.10.
After I start up the system, the wifi is not getting connected by default ( which was getting connected automatically in the earlier version). So I right click on network manager and click on 'Enable Wireless' option and it gets connected. So far so good. Now I close the laptop lid - it goes to sleep mode and after it wakes up, the wifi never gets connected. When I right click on the network manager icon, the 'Enable Wireless' option is disabled! I have to reboot my machine to get connected!
Here are the details:

Laptop : Lenovo U330
lshw -C network output:

Could someone guide me to fix this please. Thanks in advance.

Exact same problem here.

I think I found a solution:

sudo rfkill unblock wifi

Hey, that worked! Thanks for that command
But isn't there any permanent fix for these two issues:
1. Enable wireless automatically on startup
2. Automatically connect to wireless rather than running the above command everytime system is back from sleep mode. (even after running the command, I've to right click on network manager icon and click on Enable Wireless option to get connected)

Same problem for me - I'm running on a Lenovo IdeaPad S12 with proprietary driver enabled - this is my lshw:

Same problem here and also I can't connect to the wireless networks that I create !!!

Running 10.10 on a Lenovo IdeaPad Z560 , didn't have this problem in 10.04.

Still having the problem. Lenovo ideapad V460...

Looks like we lost something from 10.04...

Lenovo U series with Intel 5100 AGN

Once enabled again (from link above) Wireless N connections are locking up
after a while. This device was working perfectly in current 10.04 with all
updates. It seems stable on G connections. I saw this exact behavior on
earlier versions of 10.04

Anyone know if there is a "backports" package that will fix it for now?
