Bug Description

Not sure how long this has been happening since I recently switched out routers to a dd-wrt and it likes to restart the connection whenever you make a change. It could have been happening before that since I switched out the other router because it was acting weird (not related I don't think, but wasn't dropping connection ... but it had 4 amplified aerials). New router has internal, but my phone is right next to me and its connection is worse (SNR wise) but stable. Laptop is NOT stable.

Seems to be similar to Bug #1349108, but that one was a different driver. And I don't want to post the entire log since I've got the dd-wrt, the cisco, cron jobs, and all kinds of stuff going to my syslog, and I checked .. the mrtg run doesn't always preceed the "lost" message, but it was fairly common that it does. The same messages repeat forever (weekly log rotations show from 69 to over 250 occurances per log file). Let me know what other info I can give. This was stable some weeks ago, but I can't tell you what I changed or when.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.17 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Wow, installing 3.17 was a mess. X is black because fglrx wouldn't install an updated module and Xorg is won't fall-back to the open-source driver. So, I tried to reinstall fglrx, which didn't fix it, but broke it for my 3.13 kernel! Luckily I have an alternative install (Sabayon with kernel 3.16, and it seems to have the same issue).

I don't have time to fix fglrx right now, so I'm going to boot it to 3.17 and let it stay black. I'm leaving for a few hours. I'll check the logs when I get back and see what its like. *sigh* Thats how it always goes - try to fix one thing and break 20 others.

OK, after leaving the system running for a few hours running 3.17, I'm showing 5 spurious disconnects in the same number of hours with the same information in the logs as above. And I don't know if it helps, but I found someone else is having the same problem with a very similar notebook, so it may be something particular to this model? I can't understand the details or if there was a solution since it's in German. But if it helps, it's http://forum.ubuntuusers.de/topic/rtl8188ee-wlan-unkonstant-unverlaesslich/

I can confirm major issues with RTL8188EE on elementary os freya beta.

I am on a new HP Pavilion with this card, it works perfectly in windows but on elementary the perfomance is sketchy at best and often fails to connect or work at all.

I have tried installing driver directly from Realtek, as well as the one here: https://github.com/lwfinger/rtlwifi_new
Both with no noticeable improvement.

I am too scared to try kernel update, would appreciate an update if anyone has found a good fix.

Hmmm... switched to EoP and gave up on Wifi. I also gave up on
Elementary... just wanted plain Gnome and a distro that couldn't do that
seems backwards and I was tired of bugs.... now I have all new bugs!

I will try to give the Wifi a test. I didn't see anything about realtek
in the changelog, but I'm running 4.0. Do you need a 4.0 test or just 4.1?

I encounter this issue on Loki. I couldn't work properly on my laptop because of this issue for weeks!

Unfortunately there is no any solution which works on Elementary OS.

Even the most famous solution for Realtek wireless card cannot help with this.

lwfinger has tried to understand my issue. He'd written somethings about Elementary network manager:

"
I am not going to install Elementary, but I downloaded it and ran it live. When I unloaded and reloaded the driver, the network management system did nothing. That is an exceedingly fragile bit of user space code. It reminded me of most distros 5 or 10 years ago. I am afraid there is nothing I can do for uou. Try some other distro!
