Have just bought the iBoost wifi booster from www.motorhomewifi.com And can't say how pleased I am with it! It's not cheap at about £160, but it works brilliantly! We are on Marjal at Guardamar, and the wifi signal is dire, but this booster has made as quick as broadband! I had trouble ordering online - due to the rubbish signal - and the guys were very helpful, even offering to phone me to take my order! In the end it arrived in Spain in five days, and was very easy to set up. I have nothing to do with the firm, but have been struggling with site wifi for two years now, so this is a revelation! Thought I'd let other fun steers in on the secret!
