wifi problems with lenovo g580 and ubuntu 12.10
i followed the these instructions:
STA - No Internet access
If you do not have any other means of Internet access on your computer, you can install the bcmwl-kernel-source package from the restricted folder under ../pool/restricted/b/bcmwl on the Ubuntu install media.
Note: The bcmwl-kernel-source package depends on the linux-headers packages so you may need to first retrieve the appropriate package(s) from the online repositories. A running LiveCD/LiveUSB environment has these packages (allowing the wireless to work), but an installed system may not. Make sure you have the linux-headers package that matches your current kernel version, plus the appropriate generic header packages so that they are automatically updated on a kernel upgrade. To find out your current kernel use the command:
uname -r
To find what linux-headers packages you have installed use the command:
dpkg -l | grep headers
Systems installed from CDROM can add the install CD as a package source and install bcmwl-kernel-source using apt-get as above. However, if you want to do it manually then the instructions are as follows:
Navigate the install media and install the packages listed below by double clicking OR install the packages consecutively from a Terminal (in the commands below the install media is mounted at /cdrom, but yours maybe different):
../pool/main/d/dkms cd /cdrom/pool/main/d/dkms sudo dpkg -i dkms* ../pool/main/p/patch cd /cdrom/pool/main/p/patch sudo dpkg -i patch* ../pool/main/f/fakeroot cd /cdrom/pool/main/f/fakeroot sudo dpkg -i fakeroot* ../pool/restricted/b/bcmwl cd /cdrom/pool/restricted/b/bcmwl sudo dpkg -i bcmwl-kernel-source*

and after a restart wifi was working fine.

I just bought a Lenovo G580 laptop, and installed Ubuntu 12.10 on it, everything works fine except for the WiFi connection, it connects fine but keeps dropping every few seconds and even when connected its extremely slow and Ubuntu will take a while to find the network to begin with.
The connection is working fine on windows, what is the problem?
The wirelss adapter is:
Broadcom 4313
specific model:
BCM4313HMGB BGN
thanks
