I have a personal Ubuntu Server that works just fine. I took an old work laptop (Dell Vostro) that used to have win7 installed. Since installing ubuntu, every 20 min or so while I am using Chrome, all the bars on my wifi signal disappear and the internet does not work. It was def not the router because everything else was working fine. At first I just rebooted and it came back. I figured it was a fluke thing until it continued. It doesn't have any issues if I am just using the laptop. But if I am using a browser, it keeps happening.
I tried to reset the drivers via the terminal.
$ sudo /etc/init.d/networking restart
$ sudo service networking restart
stop: Job failed while stopping
start: Job is already running: networking
Neither cmd did anything.
I then tried unchecking Wifi Enabled via the GUI. When I re-checked it, wifi started working again. Since then, this has worked every time.
I am wondering if anyone has any ideas on what the problem is and if you know of a permanent fix.
I am currently trying to figure out exactly what checking and unchecking the WIFI does.
答案1
well, i dont know how amazingly this would work, but you could try:
ifconfig wlan0 down
ifconfig wlan0 up
sudo service network-manager restart
or even use wpa_supplicant, for which you can find a great guide here: Connect to WiFi network from command line in Linux - blackMORE Ops

If sudo service network-manager restart fixes the problem, you can make a script and run it through cron every 10 minutes or so.
