[Bug 1430509] Re: Realtek RTL8723AE can't connect and it's slow
Hello.
Today i've done some more accurate tests.
I've downloaded the ISO from UBUNTU.COM. Same ISO, same version (amd64),
same WiFi network with same connected devices, i've tired to download it
twice from each kernel, almost 5 mins in download before record the
speed.
---------
Windows 8.1:
starts at 1Mb/s and then it goes stable to 800-850 kb/s
---------
Ubuntu 15.04 with Kernel 4.0 RC3:
starts at 90 kb/s and then goes up to 190 (stable). Some times it speed up to 400 kb/s but it's not stable, e.g. It downloads at 400 kb/s, then stops for 2-3 seconds and downloads again. I think that the medium speed is always about 190 kb/s...
---------
Ubuntu 15.04 with Kernel 3.19
It often doesn't connects to the wifi. When it connects the speed is stable to 100 kb/s
---------
Ubuntu 15.04 with kernel 3.16
It seems to connect every time, and it's a little faster than 3.19. It goes stable at 110-120 kb/s
---------
Ubuntu 14.10 (LiveDVD) with kernel 3.16
Works live in 15.04 with kernel 3.16
-------------
So the Kernel 4 seems a little better than the others. 3.19 on Ubuntu
15.04 is the worst because it has connection problems and slow speed

Title:
Realtek RTL8723AE can't connect and it's slow
Status in linux package in Ubuntu:
Confirmed
Status in linux source package in Vivid:
Confirmed
Bug description:
My wireless card "Realtek RTL8723AE PCIe Wireless Network Adapter" doesn't work fine on 15.04. It works pretty fine on 14.10 and previous versions, but it's unstable on 15.04 and the most of times it can't connect to my WiFi network. Sometimes I can solve deleting the network from "Edit connections", but when i can connect the connection is unstable and really slow (40-50 kb/s in download).
The same wifi card with the same wifi networks worked fine until I've updated to Ubuntu 15.04 so i can suppose that it's a Vivid's bug
