I have a Raspberry Pi. model B, flashed with Raspbian 2014-06-20, Microsoft Wired Keyboard 600 & Edimax EW-7811Un 150M 11n Wi-Fi USB Adapter... Everything was working fine, even I created an Android application to control the PI via WIFI.
Suddenly, I am experiencing some problems... 1) When connecting Ethernet or WIFI with the Keyboard, the keyboard gets frozen and does not work anymore.
2) WIFI seems not to work anymore (I don't see the blue flashing light that indicates that is working, I see it when connecting the dongle in my Laptop)
3) Ethernet seems not to work anymore. ping raspberrypi.local -> cannot resolve raspberrypi.local: Unknown host ssh raspberrypi.local -l pi -> ssh: Could not resolve hostname raspberrypi.local: nodename nor servname provided, or not known
as I can't not have connected Ethernet & Keyboard I can't follow up what's going on, with ipconfig or so on...Anyway I've checked all the config files are OK, but I don't see that PI is getting any IP from the router...
I changed the Ethernet cable as well, even I've bought another PI, woth the same result, flashing another SD Card...
I even put my PI in the fridge for 2 hours :-)
Everything is quite surreal
