CONNECTING SHED TO INTERNET

[Sydswan]

We are connected to the Internet via Satellite.

The modem is in the house, which has metal walls and roof. 

The wifi does not extend much beyond the house unless the door is open.

I am wanting to have some sort of wifi in my shed which is approx 20 metres away, is made of cement sheet and has a metal roof. 

Any suggestions on how this can be achieved economically would be appreciated.

Many thanks Syd

   Define "expensive".  We could go on like this for quite a while.

   I've dealt only with unshielded twisted-pair in (more-or-less) free
space.  I don't know if metallic (or buried non-, for that matter)
conduit would cause problems.  You might want to do some reading, or
wait for more free advice to roll in.  In free space, you should be good
up to 100m.  I'd guess that 20m of almost anything would work, but what
do I know?

   What you'd need would be a wireless access point.  Almost any router
can be crippled enough to make it work as a wireless access point.
Conceivably, you might find a purpose-built WAP which costs less than a
similar full-function router.

   Define "economically"?  The shed has power?  Other constraints?

   If running an Ethernet cable is unacceptable, then a pair of
Powerline adapters might serve.  These use building power wiring to
emulate a real/simple Ethernet connection.

   Then, if you need wireless in the shed, some kind of wireless access
point (possibly a wireless router which is configured as a WAP).

Thank you for your response; 

Economically for me is not acquiring expensive equipment.

I could run an thernet cable in conduit across to the shed; 15m shouldn't cause much loss of signal?

i would then need to acquire a second router. 

I will follow up your suggestion re power line adapter- sounds like a plug and play system.

much appreciated Syd
