we've literally just had fibre optic installed, stated speed of up to 38 mb/s to the house, however the guy has used a 15 meter cable going from the phone socket (rj-11?) to the modem to connect it, does this slow the connection down as i am only getting speeds of 15-17 mb/s, also the router connected to the modem is wireless N rated and the adapter im using is wireless G rated adapter, im a realist and expected to lose a bit of speed but not that much!!!! so my question is: is there a bottleneck? or are these speeds normal?

Not even close to correct. RJ11 is a physical plug that can have 3 pair if you really wanted it to but this is not really related to what is run into the house. In almost all cases you will find rj11 connection on dsl type of service. Even the old basic DSL could run 8m at short distance. The newer vdsl that they extend optical with runs 52m or even more. Nobody has used old analog dialup protocols for 10 years. Besides the wire is all that is important I could build a adapter to run ethernet on rj11 jacks as long as I had cat5e cable.

You always...

Yes there is a bottle neck. RJ11 is a 4 wire standard and is intended for analog communications - I.E. Voice. (I Think around 56Kbps for speed - though I am not sure.) RJ45 is an 8 wire standard - with Cat5e it is capable of 1000Mbps.

So - in plumbing terms - you have an 8" main water pipe connecting to 1/4" copper. If it were possible to connect via Coax or RJ45 (or better yet - FIBER) - you could get a lot higher flow of data.

Using the water analogy - the wireless is a sprinkler system. No matter how much you try to push through it - it has a limit to what it can handle.

The ideal situation for a home network is to have hardlines (cat5E or better) to your work computers and high bandwidth devices and have wireless for your various other devices.

You always want to test speed with ethernet cable plugged directly into the router. Wireless is too unpredictable to know if it is the wireless causing the issue or you have a actual network issue. It would not be uncommon to only get 17m using a old 802.11g adapter but you need to test with wired to ensure that really is your problem.
