Lenovo G50 keeps disconnecting at random intervals

[VarSwrd]

Was asked to make a separate topic for my issues. Running Mint 17.2 (Rafaela) on a Lenovo G50 and a situation keeps happening when I can't connect to any website all of a sudden but the connectivity icon on the bottom-right shows as still connected. The other topic recommended I check here:

https://sites.google.com/site/easylinux ... BE-chipset

When I ran lsusb I got two different RealTek devices and a bunch of other stuff that the page does not mention.

Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

What should I do?

[JeremyB]

Did you follow the instructions from the linked site? You can ignore the lsusb results, the first realtek device is the bluetooth and the second is a memory card reader

[VarSwrd]

I read the instructions, and it said I needed to run lsusb to determine the chipset. What part of the output determines the chipset, then? I didn't see anything in the output listed in step 1.

I am completely new to using Linux. What am I doing wrong?

[JeremyB]

Something must have got messed up, do

Code: Select all

echo "options rtl8723be fwlps=0" | sudo tee /etc/modprobe.d/rtl8723be.conf

Reboot

If you want the bluetooth to work, I can help with that

[VarSwrd]

Okay. I ran that command, and after a while the disconnection problem is still occurring. The only difference is that the WiFi indicator now properly shows that I am disconnected when the problem occurs.

I ran lsusb again and the output is the same. What to do next?

[JeremyB]

Don't worry about lsusb, post the results of

I didn't see what I was expecting, so I will have you run this in terminal

Code: Select all

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && \
chmod +x wireless-info && \
./wireless-info

I don't need to see the results from terminal but just the contents of the wireless-info.txt file that is created

The disconnects might be caused by the encryption used by your wifi router. If you can change it, change it to WPA2 only

I have this same Realtek RTL8723BE wifi card in my Lenovo G50-45 and it's working fine. If you are having disconnect issues it could be the router or its settings as previously said or perhaps your wifi card is flaky. Try changing your router config - reset it to factory defaults and try using it like that for a while. Swap a spare or a friends router to see if it still occurs. Purhase a new RTL8723BE wifi card - they're only US$10. Those are all things you can try. See my post here:http://forums.linuxmint.com/viewtopic.p ... 1#p1063693

updating this thread to another one with more info and a potential fix... http://forums.linuxmint.com/viewtopic.php?f=53&t=204172

Probably a too late reply to this but the G50 doesn't get on with some access points. I have a friend with one and it doesn't like Broadcom SoC based routers in windows and Linux. Think it's a firmware problem. We got a cheap USB WiFi stick and that works fine.

I'm using 100meg Ethernet cable dangling everywhere now as I've had enough of troubleshooting wireless problems. It's a breath of fresh air to be honest.
