Broadband outside?

[LauraDavies]

I have just built an extenshion which a outside the house probably about 20 feet away. The internet is terrible in the office. I have spoken to friends to have recommended a mesh network and it is not grat still 14mbps on a 150mbps connection.  I been recommmended a hard wire in to the office Cat 6 cable I belive. 

Who would I contact to get this done? I am not with BT. What trade would do this, an electicion?  Was wondering if anyone had layed Cat cable outside the home befour and me doing it is out the queshtion can't be drilling holes. 

Thanks for any help.

Running ethernet cable is not a specialist task: the only slightly tricky bit is crimping connectors on the ends which requires a little knowledge and a purpose built tool.  Punching down cable ends onto a faceplate doesn't even require that.  An electrician with some networking knowledge might be appropriate (although some have no idea that ethernet doesn't run in rings) or a competent handyperson.
