I have a Toshiba Satellite C55-A5300 laptop. When I run

lspci -nn

it shows

02:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8188EE Wireless Network Adapter [10ec:8179] (rev 01)

It has always had the common problem others have asked about here (and many, many other places on the web) where it would connect, then drop the connection at random intervals. I tried every solution I could find, here & elsewhere, and they always caused errors after running "make" (more details below), but as I could still connect to networks I just dealt with it.

I upgraded to 14.04 a few days ago and now it won't connect at all - I need help getting this to work.

I originally followed the instructions posted by chili555 found here: Wireless not working on Toshiba Satellite C55-A5281, but I get the following errors when running "make":

/home/dan/backports-3.11-rc3-1/net/wireless/sysfs.c:151:2: error: unknown field ‘dev_attrs’ specified in initializer .dev_attrs = ieee80211_dev_attrs, ^ /home/dan/backports-3.11-rc3-1/net/wireless/sysfs.c:151:2: warning: initialization from incompatible pointer type [enabled by default] /home/dan/backports-3.11-rc3-1/net/wireless/sysfs.c:151:2: warning: (near initialization for ‘ieee80211_class.suspend’) [enabled by default] make[6]: * [/home/dan/backports-3.11-rc3-1/net/wireless/sysfs.o] Error 1 make[5]: [/home/dan/backports-3.11-rc3-1/net/wireless] Error 2 make[4]: [module/home/dan/backports-3.11-rc3-1] Error 2 make[3]: [modules] Error 2 make2: [modules] Error 2 make1: * [modules] Error 2 make: * [default] Error 2

I have no clue how to diagnose the problem or how to proceed from here. I also don't know what information one might need from me in order to move forward. I'll be happy to share anything you'd like to know if it results in this thing (finally!) working properly.

Thanks in advance for any / all help.

ETA: I did see this post - Realtek 8188ee wireless driver SOLVED - and it looks like it is discussing the same problem I'm having, but I cannot for the life of me figure out what

I had to add the testing repository to my /etc/apt/sources.list

means, so I am still stuck.
