I have recently been having a problem where I leave my raspberry pi on connected to the internet as I am running an a apache server on it and when I come back to the Raspberry Pi about a day later the dongle isn't flashing blue like it usually does. I go to the wpa_gui and it says as the status 'Could not get status from spa_supplicant'. I tried taking out the dongle half way and then pushing it back in. This seems to get it working again but I had it working before where I could just leave it and it would stay connected to the internet. Does anyone have any ideas what I could do to stop it disconnecting?

    Have you checked the logs? /var/log/udev and /var/log/dmesg might be good places to start. – Jacobm001 May 14 '15 at 22:03
  • what do i look for inside the dmesg? – Matthew Haywood May 14 '15 at 22:07
  • I have changed the usb ports of the dongle to see what happens because before it all started to happen I seem to remember that i had my dongle on the bottom usb port and the usb hub on the top one. – Matthew Haywood May 14 '15 at 22:19
  • It might also me a problem with your router. You should look into your router settings and see if it refreshes the router on a 24 hr basis for example. – NULL May 15 '15 at 01:32
  • Actually this issue drove me crazy for weeks. It turned out I hadn't installed proper drivers for the dongle I choose. I just double checked.. Mines been up now 202 days, so I think the problem is solved... Originally I would get 12-36 hours before I couldn't ssh in anymore. Google the dongle's model number. – Tyson May 15 '15 at 01:38

    great you got it sorted. Please add your solution as an answer with as much details regarding the driver versions and how you identified/updated them when you get the chance. – rob May 15 '15 at 07:22
  • I think I had a dongle like that -- at first it used to disconnect regularly and I used this. Then at one point I noticed the blue light, which previously blinked slowly, stayed steady, and connecting without that script was fine. My guess is the driver was upgraded, but I never looked into that. – goldilocks May 15 '15 at 09:50
  • WRT logs you want to try and pinpoint when the connection went down and look in /var/log/dmesg or /var/log/syslog (which contains everything by default on Raspbian) around that time for anything that is obviously a wifi device failure. – goldilocks May 15 '15 at 09:53
  • I think I have got it working again, I did what i said in the comment yesterday and it has been over 24 hours and i haven't had to take out the dongle and put it back in yet. – Matthew Haywood May 15 '15 at 23:30

Maybe your wifi dongle entered in power saving mode, toit, you have to add "wireless-power off" in your "interfaces" file

1/ Type

sudo nano /etc/network/interfaces

2/ Add at the end of file

wireless-power off

3/ Reboot by typing :

sudo reboot
