After all the grief I had earlier this year with Vodafone about getting my money back on a sure signal (which I did) I also bought a sure signal as my signal didnt improve at home.  I now wonder how I lived without it!

This blog post by Mark Wilson does the business. I need say no more…..

*Edit*

I have just noticed that if you loose your internet connection. (Which I do every night when my Linksys 54G dd-wrt Router restarts at 3am.) Then the suresignal seems to need a reboot to get it to reconnect. However I got around this by plugging it into the Orange Adsl Router which is before the Linksys.
