>solved> realtek RTL8723BE PCIe Wifi adapter not working.

humorgoesalongway · Post by **humorgoesalongway** » Mon Dec 19, 2016 4:18 pm

I am relatively new to the linux mint scene and just installed 18.1. The driver for the realtek wireless is working and I tried some commands from various topics in the forum that made the wifi adapter pick up the router I have at my house(some helped but I'm still having the same problem). However, whenever I activate the wifi on my computer I can only see my wireless network for a quick sec and then the switch for wifi goes from on to off and nothing else happens. Could use any help.

Is this an HP laptop?

I've tried another WiFi adapter I got and I get the same problem... The driver is recognized for the Adapter but when I turn the WiFi on it won't stay on

See the wireless script link in my signature and post results. When you replaced the card was there 1 antenna wire or 2?

The card listed here is the internal wireless card. I tried another realtek 802.11e card that came on the screen but both did the exact same thing. I turned them on and then they shut off almost instantaneously. Here is the results of the script.

Should be an easy fix

Code: Select all

echo "blacklist acer_wmi" | sudo tee -a /etc/modprobe.d/blacklist.conf

Reboot

Awesome!! Thank you so much. One more question if you could answer it. the realtek 802.11n Wlan external adapter picks up the wifi signal at 60% but the internal wifi adapter realtek rtl 8723be pci does not pick up the wifi signal barely at all(not functionable). It's just a usb port and not that big of a deal but if you could answer it i'd appreciate it.

humorgoesalongway · Post by **humorgoesalongway** » Mon Dec 19, 2016 9:23 pm

I'm sorry even with the realtek 802.11e the wireless is intermittent. I am in my house and so is the router. it should be pretty high and the signal should not disconnect.

Post by **JeremyB** » Tue Dec 20, 2016 7:00 am

Some newer HP laptops use only one antenna with the rtl8723be, the following code should help you set the ant_sel parameter to the correct antenna

Code: Select all

sudo modprobe -r rtl8723be

Code: Select all

sudo modprobe rtl8723be ant_sel=1

Code: Select all

iwlist scan | egrep -i 'ssid|quality'

Then we check the second option to find which one works better

Code: Select all

sudo modprobe -r rtl8723be

Code: Select all

sudo modprobe rtl8723be ant_sel=2

Code: Select all

iwlist scan | egrep -i 'ssid|quality'

If ant_sel=1 is better

Code: Select all

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

If ant_sel=2 is better

Code: Select all

echo "options rtl8723be ant_sel=2" | sudo tee -a /etc/modprobe.d/rtl8723be.conf

humorgoesalongway · Post by **humorgoesalongway** » Tue Dec 20, 2016 10:08 pm

I did ant sel 1 but in the network settings the realtek rtl8723be pci internal modem is only picking up 34% while in the results it shows different statistics. The realtek 802.11e external modem now shows 0 signal strength. Hear is what it said.

It might be a module glitch for the external USB wifi that causes it to report 0 signal strength as I know Pjotr has talked about it before. Let's see if the settings were changed correctly

Code: Select all

humorgoesalongway · Post by **humorgoesalongway** » Wed Dec 21, 2016 11:28 am

Alright maybe it was a reboot that was needed. THe signal strength of the realtek rtl8723be pcie wifi adapter is at 86% which is functional, but the 802.11e is at 60%. I'm just curious why the difference.

humorgoesalongway · Post by **humorgoesalongway** » Wed Dec 21, 2016 11:49 am

Another wierd thing is that when I reboot the signal strength seem to swith. The realtek internal card picks up 60 and realtek 802.11e picks up 100. Reboot and the signal strength seems to reverse the internal card is at 100 and the 802.11 is 60. I just want to see if I can get both cards at 100. Also. I'm picking up a wifi signal at 100% that isn't in my household. Granted I live in a twin, but I don't understand why there's would be stronger than ours. Thank you.

Post by **JeremyB** » Wed Dec 21, 2016 6:05 pm

I don't really know how to increase the signal strength but if your wifi router has the option to use a 20MHz channel width instead of 40MHz it may help with the signal strength
