HP Probook 455 G2 RTL8723be WiFi not working for Mint 17.1

Post by drhodes »

I am having an issue where my WiFi is not functioning. I am using a RTL8723be chipset, and after a clean install of Mint 17.1 Network Manager shows wlan0, but says the state is down. I can toggle the WiFi off and on, however there is no networks showing. I have done a ton of researching solutions and have followed several suggestions for other issues. Nothing I do seems to help. Here is some of the things I have tried:

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
sudo reboot
------------------------------------------------
wget https://www.kernel.org/pub/linux/kernel ... 1-1.tar.gz
tar -zxvf backports-3.19-rc1-1.tar.gz
cd backports-3.19-rc1-1
make defconfig-rtlwifi
make
sudo make install
-----------------------------------------------
I have tried changing from kernel 3.13.0-37 to 3.13.0.39 and to 3.16.0-33. Everything I try seems to have the same result, WiFi can be toggled on/off but no networks are showing and the IF state says down.
Here is the result of a inxi -Nnx:

Network: Card-1: Realtek RTL8723BE PCIe Wireless Network Adapter driver: rtl8723be port: 3000 bus-ID: 02:00.0
IF: wlan0 state: down mac:

driver: r8169 ver: 2.3LK-NAPI port: 4000 bus-ID: 01:00.0
IF: eth0 state: up speed: 100 Mbps duplex: full mac:

Here is the log of toggling off the WiFi then on again:

Any assistance would be greatly appreciated.

Re: HP Probook 455 G2 RTL8723be WiFi not working for Mint 17

Post by JeremyB »

I would definitely try this

Code: Select all

echo "options rtl8723be fwlps=N ips=N" | sudo tee /etc/modprobe.d/rtl8723be.conf

Code: Select all

sudo iw reg set US
The card seemed to be working when the script was run but had no scan results for some reason, are there wifi access points around and are the antenna wires attached to the wifi card?

You might be stuck in hotspot mode since it looks like you may have tried it, lets delete it from Network Manager with

Code: Select all

sudo rm /etc/NetworkManager/system-connections/Hotspot
Reboot and see if the results are different

I did both of these commands.

Yes, there are access points where the laptop is. The WiFi card only has one antenna connected with this HP model, however I know that it does work because the card\driver works with Mint 17.

Rebooted and still the same result.

I just wanted to say that I really appriciate your help on this. If there is anything else that you can think of, I would really be grateful.

Re: HP Probook 455 G2 RTL8723be WiFi not working for Mint 17

This is still an issue for me. I installed the 32-bit version of Mint 17.1 and the default WiFi driver included in the install works fine. I am not sure if that is helpful information or not. My lasted attempt at troubleshooting this issue was to change to kernel 3.16-25-generic and then install the driver from https://github.com/lwfinger/rtlwifi_new.git. Any other suggestions for the 64-bit Mint 17.1?

The drivers do work. A poster on Ubuntu Forums had weak receive signal on his Stream laptop and he found that HP used only 1 antenna wire and he switched it to the other post and it works fine now. The Probook 455 may have the same issue
