I follow this (http://www.andreagrandi.it/2014/09/02/how-to-configure-edimax-ew-7811un-wifi-dongle-on-raspbian/) guide to connect my RPi1/2 to my network and it always works flawlessly.
I just installed the 3.0 beta to try on my RPi2 and now it doesn’t seem to want to get an IP address.
I get the following lines while it tries to connect to my Netgear R6100. Mind you, this hasn’t happened before.
DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 3
No DHCPOFFERS received
No working leases in persistent database – sleeping
The first line will repeat 4-6 times with different numbers after “interval” each time. This seems like a bit of a bug. Can anyone reproduce it?max0rParticipant03/29/2015 at 13:21Post count: 7
# /etc/network/interfaces auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlan0 auto wlan0 iface wlan0 inet dhcp wpa-ssid "YOUR SSID" wpa-psk "YOUR PSK" iface default inet dhcp wireless-power off
This is all I did to configure my wifi. But i didn’t use the retropie-3.0 sd card image, I installed retropie binaries with the setup script on a fresh raspian from 2015-02-16.
Does your wifi dongle work? Check with
iwlist wlan0 scan. Have you tried using a static ip?vincegunParticipant03/29/2015 at 14:39Post count: 12
Yes, it works. It’s the same one as in the link I provided. The Edimax ew-7811un.
After the system boots it just sits there and the led blinks on and off regularly a few times, then stops, then starts again. Over and over.
I haven’t tried a static IP and I wouldn’t know how to set one on this system. I’ve only ever used the raspbian wifi scan tool or the modified /etc/network/interfaces to just automatically grab one.max0rParticipant03/29/2015 at 15:42Post count: 7
You can try a static ip with
# /etc/network/interfaces auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlan0 auto wlan0 iface wlan0 inet static address 192.168.0.2 netmask 255.255.255.0 gateway 192.168.0.1 wpa-ssid "YOUR SSID" wpa-psk "YOUR PSK" wireless-power offvincegunParticipant03/30/2015 at 00:29Post count: 12
Thanks for that info. I have to go to work soon (damned third shift), but I’ll be trying this as soon as I’m able.vincegunParticipant04/03/2015 at 02:13Post count: 12
Finally got around to trying this. It seemed to half work. The unit took the IP that I gave it, but I couldn’t connect to it via winscp.petrockblogKeymaster04/04/2015 at 01:30Post count: 1827
did you reboot your router just to make sure ? I know it’s obvious, but worth checking at least.
DHCP does work on the latest image as I use it myself. Nothing specific to retropie has been changed in regards to dhcp from raspian. Could be some new incompatibility with latest kernel and your wireless chipset of course.
