RTL8723BE PCIe Wireless Network Adapter Issues -- Information+Fix

[Wirezfree]

This is for information. (mods, if in wrong place, you can move it)


I was having an issue with 2X RTL8723BE WiFi devices,
Intermittent loss of connections/slowness after a few hours after boot. (they where cheap @ $7.00/£5.00)
Device info:

Code:

dave@jetway0:~$ lspci | grep 8723
03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter

After research it appears it was added in Kernel 3.16, given I have 3.13 and is working fine, I looked for an alternative.
I found the following in a number of references, and after 5.0 days no more drop-outs or slowness occured.



First Install Driver:

Code:

sudo apt-get install linux-headers-generic build-essential git
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install
reboot

Then:

Code:

gksu leafpad /etc/modprobe.d/rtl8723be.conf

and then add:

Code:

#To "disable" certain power saving features which can cause dropouts
options rtl8723be fwlps=0 ips=0

Important reminder, If you update kernel to less <3.16 , you will need to re-compile.

Code:

cd rtlwifi_new
make clean
make
sudo make install
sudo modprobe rtl8723be

"NOTE: This code will build on any kernel 3.0 and newer. It includes the following drivers"
rtl8192ce, rtl8192se, rtl8192de, rtl8188ee, rtl8192ee, rtl8723ae, rtl8723be, and rtl8821ae

I have a device using rtl8192cu, do you know if the above would work with it?
LL2.6 -- 3.13 kernel
- I used the following link for mine, it was dropping too  https://www.linuxliteos.com/forums/netwo...ops-a-lot/

I'm not broke right now - but I have 2 of these usb adapters and should I have a use on another box..

TIA - I'll be bookmarking this one too

That is a good question..??

On the github lwfinger at the very end it states for:

rtl8192ce, rtl8192se, rtl8192de, rtl8188ee, rtl8192ee, rtl8723ae, rtl8723be, and rtl8821ae

But if you look up above at the devices listed it also lists: rtl8192cu


Maybe it was omitted from the list by accident, or maybe there is reason..??


A quick google for:  ubuntu 14.04 install rtl8192cu driver


It shows a lot of methods for rtl8192cu, but not exactly like I used.
I think you need to do some googling,
Take note of the various fix methods, then look for ones where people confirm the fix.


That is my best suggestion, I would not like to suggest you use my method, it may break something..??


GL..

Thanks!! The Ole same but different  :o  LOL
I'll poke around; most files in "cu" are 8months or older except 1 (I would assume mostly the same)

So far the thread I mentioned has it working fine. Think I better keep to the if it ain't broke don't, don't fix it. ;D
Or at least I better make solid a back up  :-X
