Realtek RTL8723be doesn't have good reception

Question

Only when I'm closer to the router, it shows any signal, but when I'm just little far from it, it is not showing wifi routers signals.

Yup ... There's no another error, only that I mentioned above.. And I almost try all the solution present in the internet... but no one method can able to solve this problem... — Swapnil Sharma, Jan 06 '16 at 18:50
I mean physical access, is it easy to replace? Some HP laptops require major disassembly to get to the wifi card — Jeremy31, Jan 06 '16 at 23:40
I don't know about it. You know It's not a external wifi card & my laptop is on warranty so I never opened it. Is it important to do that stuff as you said? There's also windows inside my laptop, in windows there's no error with my wifi card. Only when I use Linux I will get this error. — Swapnil Sharma, Jan 07 '16 at 02:47
You will have to wait for Larry Finger and the people at Realtek to come up with a solution — Jeremy31, Jan 07 '16 at 22:52

With Ubuntu 16.04 and later, go to Parameter settings as nothing needs to be downloaded

Progress from Larry Finger from here

If you installed rtlwifi-new-dkms from Pilot6's PPA, it will need to be removed with

sudo apt-get remove rtlwifi-new-dkms

Reboot, then


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

Reboot and then

Parameter Setting

sudo modprobe -rv rtl8723be
sudo modprobe -v rtl8723be ant_sel=1

Test wireless, if no change then

sudo modprobe -rv rtl8723be
sudo modprobe -v rtl8723be ant_sel=2

Test wireless again, one or the other should result in better reception

When you find that one works better than the other

echo "options rtl8723be ant_sel=X" | sudo tee /etc/modprobe.d/rtlbtcoex.conf

Where X is 1 or 2- whatever resulted in better performance, in the case of Swapnil Sharma it would be

echo "options rtl8723be ant_sel=1" | sudo tee /etc/modprobe.d/rtlbtcoex.conf

Then the parameter will be remembered following a restart

Thanks it works. But not Completely. I have to use this again and again after restarting my Laptop. `sudo modprobe -rv rtl8723be sudo modprobe -v rtl8723be ant_sel=1` – Swapnil Sharma Jan 26 '16 at 08:57
WOW... This actually works... seems to have worked for my Realtek RTL8188EE WiFi driver. Thank you so much @Jeremy31 ! This issue was really starting to bother me. – Robin Hood Mar 20 '18 at 14:00
Hi This worked fine. I faced this issue with Ubuntu 18.04 a few months back and at the time I had copied the new rtlwifi drivers from this link : https://github.com/lwfinger/rtlwifi_new After upgrading to Ubuntu 20.04, I started facing this again. This time i just checked if I needed to download the drivers again and found the link is not working. But luckily I ran the command without downloading the drivers and it worked like a charm. So all in all method is working but link is not available anymore. if Any of you has the repo for these drivers, please post it here. Cheers – Harshil Aug 01 '20 at 09:04
