Wireless Wi-Fi USB connection works and then suddently drops connection

[grofaty]

Hi,
I have installed ndiswrapper after having several problems like bug 1550915 on Ubuntu 14.04.4 (with latest updates).

All details I have performed are stored on forum: http://ubuntuforums.org/showthread.php?t=2315366 (I don't want to waste too much space on bug report).

Two commands output:
lsusb | grep Wireless
Bus 002 Device 006: ID 13b1:0039 Linksys AE1200 802.11bgn Wireless Adapter [Broadcom BCM43235]

sudo ndiswrapper -l
bcmwlhigh5 : driver installed
 device (13B1:0039) present

And wireless USB Wi-Fi key is working fine. But problem I have that wireless connection is frequently dropped. For example I execute command: sudo apt-get update
to update packages and command is executed successfully and informations from various data sources gets downloaded, but just in the middle of this download wireless connection is dropped and update packages command output freezes in the middle of download.

Sometimes I can make it work again like reboot Ubuntu, but sometimes it just stops working and reboot does not help, then after some time several try and fail wireless starts to work again. But only for couple of minutes.

I am not an expert on this field, so I don't know if this is a driver problem or ndiswrapper bug or even something else.

I hope some expert can look into this problem.

P.S. I am attaching a print-screen to prove that sometimes wireless works fine.

Thanks a lot.

This is of course very unfortunate, but there's nothing that can be done here: ndiswrapper has no active upstream developers more (last upstream change was in January 2014 (!)) and downstream we just focus on allowing it to build with newer kernel versions.

I can only *strongly* recommend you to get a wireless card natively supported by Linux.
