To my gigabit connection of KD also fully exploit I decided for this card. Software loaded directly from DeLock page. (With notebook LAN port) After restarting the router and notebook card is instantly recognized without any problems and has been running for just over a week with no weaknesses. Processing and quality are very good, solid case made of plastic and metal. No heat generation, solid connection to the RJ-45 connector. Cute Blinkelicht in green (not disturbing) displays on the left side of activity. Transfer speed is on average 93000bit- therefore more than adequate. In short: Great part at a really good price compared to an upgrade with new Lan-T1000Karte. Tip: If at KD clients / routers or no missing Konektivität appear // disable Internal notebook card and router approx.30 sec from the electrical power + restart notebook ready..
