kali linux 2017 continuosly disconnecting from wifi

[Arijit1080]

I have installed kali 2017..and using Lenovo laptop having rtl8821ae wifi card.I have dual boot of windows 10 and kali linux .When i am connecting it with wifi it is working,webpages are loading but suddenly webpages getting stop loading.it is disconnecting from wifi and it is happening in every 5 to 15 minutes after 5 and the i have to reconnect it but in windows there is no problem.I have installed the Network drivers but that did not solve my problem.If you need any further details plz inform me i can give yu any kind of information.can anyone help me plz....

I am facing the exact same problem.

I had already been looking in the forum for a solution but nothing worked until now.
To solve it I tried the following:
1. edit "/etc/resolv.conf" and changed nameserver from "192.168.0.1" to "8.8.8.8".
2. edit "/etc/NetworkManager/NetworkManager.conf" and changed "managed=false" to "managed=true".

My current workaround is to run "service network-manager restart" but as I have to do it every few minutes it's kind of a mess.

I'm also having this issue however mines not even generating the nameserver did you figure out a better fix for it?

To all,

Have you ruled out any hardware problems (i.e. router, ISP, etc)? Anything nearby causing signal interference?

[AlphaMars]

While this happens I am still connected to my router and can access its web interface. Only my Kali stick is facing this problem, other devices run fine. So the router (DNS) configuration should be fine.

Right now I am using this script as dirty workaround. It will restart the network-manager if I am loosing connection:

#!/bin/bash

while true;
do
echo "Check if connected..."
x=`ping -c1 google.com 2>&1 | grep unknown`
if [ ! "$x" = "" ]; then
echo "It's down! Try to restart."
service network-manager restart
fi
sleep 5s
done

Maybe you need to adjust the "unknown" to your system language settings.

(Realtek RTL8192cu) still the problem continues. I am using another usb wireless adapter (Ralink RT3072). no freezing on connection, no interruption in data flow, no breaks. Only the signal looks low.
