Wifi connection drops down. [SOLVED]

astinx · 2015-02-08 18:26:07

Hi, I'm having some issues with the wifi, in my notebook lenovo b5070. The main problem is that the connection drops down after 20, 30 minutes. I tried to change from NetworkManager to Wicd, but that didn't change anything. I also tried to create a profile and connect me through netctl, but again that didn't change anything. Other issues that I'm having are: Sometimes I can't even connect to the wifi, or if I can connect finally, and I try to request some website, the browser keeps idle and finally shows a "Server not found" message. Also the wifi signal seems pretty fine. I also tried change the tx, rts to the max with iwconfig, but this didn't change anything. I'm running out of ideas. Any idea?

Here is some info:

Hi, first of all, welcome to the forums! Second of all, try to eliminate the Great Wall of Text by using [ code ] tags.Preferably a few in this case

Edit: try disabling all other internet related service except the one you use as they conflict. As a test, try disabling and stopping the modemmanager.service and wpa_supplicant.service and just use your networkmanager.service

As frank604 says, [ code ] tags are your friend. They make posts much more readable.

That said, Realtek wifi tends to have issues with power saving. Try loading the rtl8723be module with ips=0 fwlps=0

astinx · 2015-02-08 21:35:55

So long I tried as Gusar said to loading the rtl8723b module with those params:

sudo modprobe rtl8723be fwlps=0
sudo modprobe rtl8723be ips=0

So far by now, the connection hasn't dropped (one hour since I made the change)
But is quite strange that when I do

[astinx@compu ~]$ more /sys/module/rtl8723be/parameters/ips
Y

I mean, the parameters changed or not? I also tried with setting with N instead of 0.

EDIT:
The drop downs come back shortly after. I find quite strange that I cannot manage the power from iwconfig

[astinx@compu ~]$ sudo iwconfig wlp9s0 power off
[sudo] password for astinx: 
Error for wireless request "Set Power Management" (8B2C) :
    SET failed on device wlp9s0 ; Operation not supported.

frank604, I do as you said and I disabled both services:

[root@compu modprobe.d]# systemctl disable wpa_supplicant.service 
[root@compu modprobe.d]# systemctl disable ModemManager.service

I will wait to see if the dropdowns comeback.

frank604 · 2015-02-08 22:09:24

You need to stop the service too. That just disables it from starting at bootup.

systemctl stop wpa_supplicant.service

etc. Check to make sure any other network managing services are stop/disable. I've only used netctl-auto, so not sure if wicd has a service but since you tried many of them, make sure they are all turned off and only using 1.

Not strange at all, you need to specify all options in a single modprobe call. So:

sudo rmmod rtl8723be
sudo modprobe rtl8723be ips=0 fwlps=0

iwconfig is outdated, try iw instead.

Thanks, the

sudo modprobe rtl8723be ips=0 fwlps=0

worked!
