I just got Pi Model B. I downloaded Wheezy on SD card and plugged in all of my cords. Everything works fine except the Ethernet port.
The LINK LED
flickers for a second while booting up, but then it doesn't do anything and they stay OFF. The browser shows NO CONNECTION.
I checked the cable, and when connected to laptop it shows connections, so the cable is still good.
I tried using 1A
and 700mA
power supplies as few people had suggested, but it didn't work.
I tried removing USB wireless keyboard / mouse, as it may drain power. Didn't work either. I tried removing HDMI too; it didn't work.
I had ordered 2 units from UK. 1 for me and 1 for my friend. The Unit I gave to my friend is working fine on ArchLinux and everything from SSH is working fine on that.
Can it be hardware problem? If yes can I use any WiFi adapters over USB?
I haven't tried the deep freeze method few suggested (keeping the Pi in fridge for couple of hours seem to make USB / Ethernet work for some folks) but I don't want to do it as it may damage the board.
