I have a Lenovo B570e laptop

After installing Ubuntu 12.10 through windows 7 the wireless keeps disconnecting and reconnecting and finally keeps asking me for the wireless password again.
I show several things I have tried.
Here is some data
my wireless card is:

AR9285 Wireless Network Adapter (PCI-Express) IEEE 802.11bgn

And here is the output of several info requests (required as I found during my search in many posts)

sudo lshw -C network

Do you mean your Ubuntu wireless disconnects whilst your Windows 7 wireless is fine? Does it still do this if you move much closer to the router? I'm sure that isn't the reason, the strength is -47dBm, but it's a possibility. –  mtdevans Jan 29 '13 at 19:06
