Realtek RTL8188CE Unstable

Doc
Just been called on a job. I'm not ignoring you. Be back later, I hope!

I believe this is the incorrect, or at least, less-than-ideal package for you:

rtlwifi_new-rock.new_btcoex.zip-rock.new_btcoex.zip (locked)

Let's begin anew. Please walk over to the router, hook up an ethernet and do:

cd ~/Desktop

Now we know that whatever we get will end up on your desktop and, hopefully, be accessible from now on. Next:

git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install

Reboot.

Hi I've done that and got rtlwifi_new on my desktop

Hi I've done that and got rtlwifi_new on my desktop

May I assume that you recompiled and the wireless is again working as expected?

[Mel_Blakey]

I did this:

cd Desktop/rtlwifi_new

make clean
make
sudo make install

And it ended with:

make[1]: Leaving directory `/usr/src/linux-headers-3.19.0-49-generic'
Install rtlwifi SUCCESS

It has made it worse (slower) and I need to undo what I just did!

[chili555]

The easiest way to load the new module is to reboot. Did you? Is it worse after the reboot?

[Mel_Blakey]

Hi Doc

Sorry, but I needed a sleep last night....

Yes, it is worse after reboot!

I did a new wifi-info.txt. it shows stronger signal, but slower speed.

[chili555]

If you wish to uninstall it, please do:

cd ~/Desktop/rtlwifi_new
sudo make uninstall

Reboot.

I doubt, however, that this will be helpful.

[Mel_Blakey]

I did the above and uninstalled and it worked reasonably until a few days ago when I did an update. It went back to being erratic.

I did the driver rebuild and it is sometimes good but most of the time it is very slugish.

The wireless-info was run with the laptop about 3 feet from the MiFi unit.

Thanks!

How close to the router or wireless access point are you? I am wondering if this is an antenna wire problem. Can you walk the computer over to the router and let us see, again:

iwconfig

You have, throughout this thread, installed, uninstalled and reinstalled rtlwifi_new. Which is this? You may be able to get some clues with the terminal command:
