some connect problems with a Digitus wireless 150N USB adapter (ubuntu 14.04 LTS)

have just installed the latest Ubuntu, and am very happy with it (>>>>>XP)

the only problem it seems to have is the wireless connection seems to drop out intermittently. the wireless does work, but consistently drops every so often - 15 minutes or so. sometimes it reconnects fine, sometimes it reconnects and just keeps asking me for a password. restart sometimes helps, sometimes not.

i am totally new to linux & almost totally computer/internet/scripts etc illiterate.

there are linux drivers of some sort on the cd that came with my DIGITUS WIRELESS 150N USB 2.0 ADAPTER (DN-7042-1 Rev. 1-0). the system seems to think that there are no additional drivers. i have copied the linux drivers folder from the Digitus cd to my desktop. (i went that far!) the included documentation for the driver is way over my head.

using the lsusb command i found out this:
Bus 001 Device 002: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter

so just wondering if i shd try to install/update driver manually, etc. & how do i do this if so.

last thing: when using XP the wireless card had its own little wireless manager program that was useless to me but inoffensive; maybe the card needs this program again (made by REALTEK)?

thanks for any of your time & advice that you can spare.

It appears that this is a known issue and bugs have been reported by the Ubuntu folks. First, here's the link that seems to resolve the issue with another user:

Be sure to read page one before implementing the fix so you can see the OP's initial post and get the whole picture.

Second, here's the relevant bug link:

I found this by typing RTL8188CUS intermittent into google's search box, FYI.

Hi, thanks for the links! My friend seems to have solved the problem by using the Windows driver off the CD, thru NDISwrapper. I guess this is an ok solution for now...
