"Hi Martin,
I'm really delighted with and enjoying the B2. As a new user I have a few queries that I can't find answers to in the FAQs - I'll submit them one by one as requested. First up is that I want to use Ethernet rather than rely on wifi. I've read the Ethernet section in the online user guide and am nervous about attempting this myself because I have no electronics experience. First, is this something that should really only be attempted by someone with relevant knowledge? Second, would attempting to fit the Ethernet cable invalidate the warranty? Any help you can give on this much appreciated. Best regards, Paul"

Hi Paul. Great question. No problem with warranty if you open B2. You don't need any electronics know how. I suggest you get hold of some flat Ethernet cable because its a bit of a squeeze with regular Ethernet cable - though it can be done. You just need to remove the two screws marked with chevrons on the back. The rear panel and main assembly will then slide out about 2cm. If the rear panel is fitted tightly just prise it out with a small screwdriver using the ethernet cables slots to get a purchase. I suggest wrapping tape around the screwdriver so you don't chip the B2 paintwork on the main body. Once plugged into the Ethernet socket on the Pi you will need to loop the cable around to feed it out the slot. If the rear panel was snug it will need the screws to be tightened and a bit of a squeeze by hand and it will snap back into place.

If you need to remove the ethernet cable from the Pi - you will need a bit of dexterity with a small flat screwdriver to lever up the Ethernet retaining clip. Don't force it. Don't rush. It will come out. I do it all the time.
