Public bug reported:

at the request of penalvch I've used ubuntu-bug linux to repost the bug
originally reported in
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/947697/

Please refer to the other bug report for other people suffering from the
same problem.

The problem: Wifi range and stability is still many times better in
Windows than it is in Kubuntu Linux (this is a dualboot system). In many
places like public libraries, where the laptop can be quite far from the
actual wifi receiver, I still have good signal and multi-MB/s download
speeds in windows while in ubuntu I cannot see the network, cannot
connect to the network or sometimes can connect but it drops every
minute or so.

Moving closer to the wifi receiver improves quality and sitting next to
the wifi receiver I have an excellent and uninterrupted connection, so
generally speaking, the driver works, but the problem is simply a much
more limited range than I have in windows 7 (again, this is a dual boot
system).

This problem has existed ever since I bought the laptop (A lenovo b570e,
running kubuntu 12.04 at that time, now kubuntu 13.10). The behavior is
consistent across all wifi networks. I've conducted quite a bit of web
searching, tried to install alternative drivers, etc but to no avail.

If I can run any additional tests or anything else that will help you
fix this issue, just let me know . My daily frustration using ethernet
cables or my daily hunts for buildings's wifi receivers results in
considerable motivation to help fix this :)
