3

I am running Raspbian Jessie (the latest one in the time of posting this) and Wi-Fi drops after exactly 1 minute. And it doesn't matter if its idle or not: even when I'm pinging my Pi, it drops after a minute. My PSU is 2 amps, which is more than enough for the Raspberry Pi 3 AFAIK. When I ran the following commands, the Pi was connected to the router through an Ethernet cable, so if any info is insufficient in the logs feel free to ask in the comments.

Here's the output of iwconfig:

As far as I see everything in this file is related to networking.

As you can see I modified 2 lines in /etc/network/interfaces, but they still don't help.

I am not using any Wi-Fi dongle, it's the Pi 3's built-in Wi-Fi thing.

  • Does it do the same thing with Ethernet? – sir_ian Oct 30 '16 at 13:56
  • @sir_ian Nope, ethernet works fine – Areg Hovhannisyan Oct 30 '16 at 13:59
  • The red PWR led does not flicker at all during this time period? – goldilocks Oct 30 '16 at 13:59
  • I never actually paid attention to that, give me a sec. – Areg Hovhannisyan Oct 30 '16 at 13:59
  • @goldilocks nope, its on and doesn't flicker at all – Areg Hovhannisyan Oct 30 '16 at 14:03
  • If you have other access to the Pi have a look at sudo tail -n 50 /var/log/syslog after the wifi goes down and post that if anything is obviously related to wifi or networking. If you don't, you can still look back though that file for the appropriate time period (which is easy enough if the time has been set correctly at that point, but awkward otherwise). – goldilocks Oct 30 '16 at 14:07
  • @goldilocks edited the question, (i had access to the pi through monitor and keyboard + ssh through ethernet and router) and there's the output. sorry for the long text out there. – Areg Hovhannisyan Oct 30 '16 at 14:12
  • You certainly aren't getting the .152 static ip. You may want to double check how you are doing this here: http://raspberrypi.stackexchange.com/q/37920/5538 – goldilocks Oct 30 '16 at 14:15
  • Let us continue this discussion in chat. – Areg Hovhannisyan Oct 30 '16 at 14:16
  • It may not be causing your problem, but having non-standard config files is NOT going to help. See How do I set up networking/WiFi/Static IP Raspbian no longer uses the traditional Debian networking. – Milliways Oct 30 '16 at 23:09
  • ok so today I will try to configure mt static ip with the instructions you gave and tell you what happened – Areg Hovhannisyan Oct 31 '16 at 10:47
  • Ok Im really late, but no success. But! I Swear it used to work a couple of hours ago! I don't know how, but it worked. I re-burnt the raspbian image on the microsd card,update the kernel (rpi-update), but still, it doesn't help! (I did all that stuff before it stopped working.) – Areg Hovhannisyan Nov 10 '16 at 15:59

    Did you found any solution? I'm also having a same problem here... – Bilguun Nov 22 '16 at 15:48
  • Nope. Still no. I think my power supply/usb cord might be to blame, but changing them didn't help. I'll probably have an answer after Christmas – Areg Hovhannisyan Nov 27 '16 at 15:21
  • Have the same issue. Wifi disconnects after 1 min. Doesn't matter if password and encryption on the AP are set or not. My router hardware is somewhat old. I can use that Wi-Fi just fine with other devices. When I set a password, RPi3 asks me every time to put in the password again, even though it's stored in plaintext in the wpa_supplicant.conf. After logging in maybe 20 times the message "wlan0: Disassociated from {SSID}" shows when hovering over the Wi-Fi symbol in the task bar and my network is no longer available in the list. Here is the strange thing: it works fine when I make an AP wit – Max N Dec 20 '16 at 10:26
  • I don't really know what happened, but it works now. Didn't change anything. All I did was turning my Pi on just like any other time. This is the weirdest thing I've ever seen in my life. – Areg Hovhannisyan Dec 20 '16 at 17:07
  • ...h the Android phone and share the 4gdata. (someone cut the comment off at the character limit.) I've ordered a wifi USB dongle and will test if that works better than the built in. – Max N Dec 20 '16 at 19:31
  • This is getting ridiculous. I have no idea whats wrong. Changed Power supplies, usb cables.. Just doesn't want to work! It is not stable. It works sometimes but then drops. If it drops it means it's gonna drop next time too. Does anyone have any idea? – Areg Hovhannisyan Jan 28 '17 at 05:13

  • this line "raspberrypi wpa_supplicant[549]: wlan0: CTRL-EVENT-DISCONNECTED bssid reason=0 locally_generated=1" seems to try to tell you what is going on. It looks like it's not the device itself, but the router. the internetz seems to agree that you should attempt to switch the channel your wifi router is using. – Mircea Feb 10 '17 at 17:59
  • Switching the channel does seem to help. I am still keeping track of things, because I'm not 100% sure that this is solved forever. Will keep you guys updated. You helped me so much. I love this community. – Areg Hovhannisyan Feb 11 '17 at 06:28
  • Ok just a quick update It seems like whenever my router put the wifi channel to 13 the wifi started dropping. No idea why though. – Areg Hovhannisyan Mar 11 '17 at 14:11
