Wifi dont reconnect - kraleksandr - 14th Feb, 2013 01:57 PM

My PI connected to the other world through wifi stick. 20 minutes ago I rebooted my router and now I cant connect to my RPi through SSH, samba, etc. Why wifi isn't reconnects?

did you already try another reboot? and what wifi stick do you have (model)?

RE: Wifi dont reconnect - kraleksandr - 14th Feb, 2013 07:25 PM

ANother router reboot? Yes. It didnt help.
Wifi stick is "rolsen mu3-wn823n".

Did you already try connecting the wifi stick to an powered USB hub?

RE: Wifi dont reconnect - kraleksandr - 14th Feb, 2013 09:00 PM

No, you dont understand. Wifi works (60Mbit/s).Samba works over wifi. SSH works over wifi. But if I reboot my router, RPi becomes offline. Even 20 mins after RPi still offline.

The software does not automatically reconnect yet

RE: Wifi dont reconnect - kraleksandr - 14th Feb, 2013 09:38 PM

Okay. What about next version?

RE: Wifi dont reconnect - Koenkk - 14th Feb, 2013 09:44 PM

It does not have that either, however I may have found a solution, what kind of network protection do you have (E.G. WPA, WPA2, WEP).?

RE: Wifi dont reconnect - kraleksandr - 14th Feb, 2013 10:05 PM

WPA2 '

RE: Wifi dont reconnect - Koenkk - 14th Feb, 2013 10:24 PM

Can you try the following:

SSH in and change the /etc/network/interfaces file to this

Code:

auto lo

iface lo inet loopback

iface eth0 inet dhcp

allow-hotplug wlan0

iface wlan0 inet manual

wpa-roam /etc/wpa_supplicant/wpa-roam.conf

iface default inet dhcp

Now execute this command

Code:

sudo nano /etc/wpa_supplicant/wpa-roam.conf

Fill the file with this (of course change the ssid and pass to your situation).

Code:

update_config=1

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev

network={

        ssid="ssid"

        psk="pass"

        id_str="home"

}

Now execute

Code:

sudo ifdown wlan0

sudo ifup wlan0

from now on wlan0 should automatically reconnect

I think it was bad idea to try this through wifi Big Grin

Even with down && up in one row.
Anyway, Next router reboot will be between 02-09 AM (GMT+4).

I cant understand this Big Grin

Looks like it works (at 3rd attempt), autoreconnects I'll test later.

How fast does it reconnects and did you noticed any side effects?

RE: Wifi dont reconnect - kraleksandr - 15th Feb, 2013 02:29 PM

1) Faster than router connects to the Internet (full reboot 93sec)
2) I dont know what I must look for. At first sight everything works as before
