anyone know of a supplier, I can't seem to find one that's the right version.

One here on ebay Mt8

Cheers for that mate but a bit pricey, I was looking to spend about a tenner but can't find one with the correct version number.

My bad, I need one for my dm800

cant you use homeplugs,i know they abit dearer on what you want to spend
but i think they better imv

Vonet Wifi bridge or any standard wifi bridge will work fine. I use a SMC Networks 54G wireless bridge. Theres no USB port on a Dm500 so traditional USB dongle cant be used,
