As my computers & router are upstairs I was keen for a device that would play my video/music/pics from my computers direct to my main TV downstairs so cutting out the need to convert everything onto disk.This Hauppauge WMVP seemed perfect.
However when I set it up,using the wireless connection to my Sky Netgear, it detected the router straight away but could not obtain an IP address no matter what I tried (I have 30+ yrs computing XP,both hardware & software).I checked the Hauppauge forum and,sure enough,I was not alone as the problem had been discussed throughout last year with no solution provided by the firm.I emailed the UK office but got no reply after a week so I phoned them."Yes, it's a known fault but all the techies are in the US so you need to email them", which I did.After another week of silence I returned the unit as not fit for purpose - all credit to Amazons great return procedure - and I am now looking at a similar product by D-Link.
I did connect the WMVP via cable and that worked reasonably well but I do not want a Cat5/6 cable running all round my house.
I am sure this unit will work with some routers,trouble is there is no list to say which ones.
