Realtek RTL8723BE weak wifi signal

Looks like there might be some ground-breaking progress on this one with a s/w fix: https://github.com/lwfinger/rtlwifi_new/issues/28.

I tried the driver from rock.the new_btcoex branch and it is working fine on my HP x360 13-s laptop.

Here is what I did:

I downloaded the code from https://github.com/lwfinger/rtlwifi_...ock.new_btcoex , unzipped it and then:

$ make
$ sudo make install
$ sudo modprobe -rv rtl8723be
$ sudo modprobe -v rtl8723be ant_sel=2
sudo ip link set wlp2s0 up
sudo iw dev wlp2s0 scan

The scan then showed all networks with expected signal strength.

To make the settings permanent:

sudo echo "options rtl8723be ant_sel=2" > /etc/modprobe.d/50-rtl8723be.conf

Note:
I had to use the parameter ant_sel=2 even though my antenna is connected to antenna input #1 !
Using ant_sel=1 (what I tried first) did not work.

That's awesome. This is a much better solution than having to take the box apart. I'm going to leave mine as-is, though. The downside is that you need to co-locate your laptop initially right next to the Wi-Fi router (within about 3 to 5 feet) in order to download the new driver, but it is a portable laptop after all!

This worked for my HP Stream 11. I selected ant # 2 and now I have excellent reception and range using Linux Mint 17.3. Best part is I didn't have to rip apart the laptop.

SOLUTION for my particular case (HP Stream 11-r010 Cloudbook with N3050 Celeron and HP Model No. 792204-001 30x22mm M.2 Wi-Fi card): Moving the single antenna cable from one connector to the other (as shown in the attached diagram) solved the problem. This would explain why the laptop worked only when sitting right next to the Wi-Fi router: With Linux the card is configured to use the other connector compared to Windows. Now I am two floors up from my router and connected well with Xubuntu 14.04. With Xubuntu, all the hotkeys work. I tried Mint 17.2, but I was unable to adjust the display brightness. I am still going to test out the Panda Wi-Fi dongle when I get it.

Awesome! My Wi-fi now working fine on my HP Notebook 14-af105AX - thanks for the help, pic and follow up instructions!

Hello guys.
I have the same problem but this post is a bit confusing, I don't really get what I have to do to fix the problem.
I already tried post #52.
Can you please help me with this?

Thank you!

Thank you!

Please replay the steps you took following post #52 above. If it isn't working, then I suspect one of the steps ended in an error. Please post any errors and we'll try to help you fix them.

If you are having trouble remembering, you can see the last (1000? many??) commands you issued in the terminal with:

ErmenegildoRos remember to take the correct name for your computer. The post #52 say wlp2s0, you can look what is yours with the ifconfig command (discard eth and lo).

By the way, I try it in a hp stream 11 2015 (r000ns) with no result. May this is a fix just for some computers...

I suggest you start a new thread and post the wireless script mentioned in the stickie at the top of this forum and we'll be glad to help.

Hi,

I have successfully installed rock.new_btcoex.zip on my system and changed the antenna to 2. Now I can see all the available WiFi networks around and also the signal strengths are good, However, for some reason I am unable to connect to my network. It simply fails to connect.

I am using HP-15 AU006Ax
