As a general point with Iberbanda, make a hard copy note somewhere of your IP address, gateway and DNS servers. You will need them to configure a router anyway.

The crappy wireless router that Iberbanda provided lost its memory and I had to call them to get the settings. I have junked that router as it wouldn't get a signal through even one of my old caseta walls. A Buffalo HP is now doing the job brilliantly.

You might like to know that there are various VOIP phones available which will work on a WiFi network. I use my Nokia N95 mobile at home and at various bars with WiFi to make free calls to the UK. I also get a UK 'landline' phone number which makes it so much easier to get a call back from UK parties AND I can call 0800 and 0845 numbers very cheaply. Great when dealing with the government, NHS etc.
