OK... I have a lovely office in my garden (converted from a brick built shed) but no INTERNET    I have several ideas how to get it out there, but would welcome some suggestions and advice.

My MAIN TELEPHONE socket is at the front of the house in the living room.  I have an extension of about 8 metres running into the dinning room where the netgear wireless router is PLUGGED in (this currently supplies my laptop wirelessly around the house).  The outside office is then about 30 metres from this, through two brick walls (one two brick and one single brick) and a false plywood wall.  The desktop I need to connect to out there doesn't have a built in wifi card.

I bought a -N netgear router (this was plugged into extension in dining room) and adapter for the desktop out there, but the 30 metres and walls meant a very very poor signal that came and went very quickly. 

What would be your advise for best signal strength and usuage, this is going to be very important to me, as I will be using log-me-in to access a computer remotely over the internet.

Thanks everyone, your time and thoughts would be very very much appreciated 

I have a suggestion. A long Ethernet Cable.

My room is about 8 meters from my router but I get my internet using a 10M Internet Cable that I have running from the computer room to my bed room.
This may be applicable here.

Just an idea. Besides expense, you could always place another wireless router outside, if there is an area such as a back deck with an overhang to protect it. Then just bridge the mainrouter to the outside router. the two routers are closer, therefore the connection should be better. Just a thought. GOOD luckYou might be able to make use of a WiFi antennae like this, or this, or maybe this, or that, or even one of these!
