Ndiswrapper is seldom the correct solution, especially for a Broadcom. My conviction is increased when you say it works perfectly in the netbook. Let's do some diagnostics. Please insert the device, open a terminal and run and post:

Your device uses the rare and elusive module rndis_wlan. There are a few driver parameters available. Let's try the most likely sounding one:

sudo modprobe -r rndis_wlan
sudo modprobe rndis_wlan roamdelta=2

This reduces the tendency for the device to try to roam to another network, at which point it disconnects,looks around, decides home was best and asks for the password AGAIN! Sound familiar?

If it helps, we can write one file to make it persistent.

There are a couple of other things we can try. May I safely assume this a stay-at-home computer that you simply want to stick on your home router? We can probably tell Network Manager who we want to default to.

Let's try a different approach. Please run:

iwconfig

When you know the MAC address of the router, I suggest you tell Network Manager to connect ONLY to it by specifying it in BSSID here. Please see attached. Hopefully, then the device will lock to your router.

How is your network configured?

ATT7341: Infra, 20:4E:7F:627D, Freq 2412 MHz, Rate 54 Mb/s, Strength 42 WPA2

This may be a big part of the problem. Is there any transmit strength setting in the router? Please see attached. Also, we might try another driver parameter:

sudo modprobe -r rndis_wlan
sudo modprobe rndis_wlan roamtrigger=-80
