I have put the wireless router near the porch at the front of the house this is where the phone line comes in i have run the earth net cable under the carpet to the back dining room so there is no no visible wires ,well hardly so far so good Sky broadband seems to be ok.
would like to borrow a laptop to check the wireless router out and see what coverage we get through the house,i might invest in a net book or a cheap second hand laptop if it was decent enough download speeds .
