Bug Description

1) install maverick UNE on eeepc 901
2) upgrade all packages to current version
3) put machine to sleep
4) resume

Expected action, wireless reconnects automatically or I can reconnect manually

Actual action, 20% of time I can reconnect if I have not changed networks
The rest of the time, the network either spins without connecting (60%) or locks up everything (20%).

My fix is to reboot. I probably could reset something, but am stilling finding my way around the Unity interface and reboot works. I will trigger this when I have a minute and add the dmesg output.

WORKAROUND: Work around (mostly) by adding the following to /etc/modprobe.d/blacklist.conf

blacklist rt2800pci
blacklist rt2800usb
blacklist rt2x00lib
blacklist rt2x00pci
blacklist rt2x00usb

I also downloaded and compiled the current version of rt2860 drivers based on instructions I found here:

See post #3.

WORKAROUND: disable power saving script for pcie_aspm and wireless.

See post #3. Not sure it was needed, but I did it. Works OK, but sometimes when I am out of wireless network range for a long time (like an hour) network-manager greys out and a red exclamation mark appears. When returning to a network, the only way I have found to reconnect is reboot. No idea if this is a driver issue or a n-m issue or something else.

With Natty, this bug is still here.

Asus eeePC 901, wifi chip Ralink RT2860, driver RT2860sta, WPA-PSK wireless network

Wifi works on boot or restart, after suspend wireless does not reconnect when resuming from sleep. BUT only on battery! If power supply is connected, then wifi reconnect after suspend normally.

Attached is dmesg with succesfull (power supply) and unsuccesfull (battery) attempts.

I found a similar bug - 773018 and suggested workaround - disable power saving script for pcie_aspm helped. Now wifi reconnects after suspend.

Thanks. I disabled both wireless and pcie_aspm and it seems to work.

Jim McKean, thank you for reporting this and helping make Ubuntu better. Maverick reached EOL on April 10, 2012.
Please see this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

We were wondering if this is still an issue in a supported release? If so, could you please provide the information following https://wiki.ubuntu.com/DebuggingKernelSuspend ? As well, can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ . However, note you can only test Suspend, not Hibernate, when using a LiveCD. If the issue remains, run the following command in the development release from a Terminal (Applications->Accessories->Terminal) as it will automatically gather and attach updated debug information to this report.

apport-collect -p linux <BUGNUMBER>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. As well, please comment on which kernel version specifically you tested.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream', and comment as to why specifically you were unable to test it.

Please let us know your results. Thanks in advance.
