Thanks for that. Is that a Lenovo H30-00? Lenovo's site is not very helpful with precise product specifications... I've been through the product page and both the user manual and the technical service manual, to no avail. Is it really that difficult for them to list what features their products have?!?
Anyway, most third party websites list the model as having a Fast Ethernet 10/100 adapter. Example. The Realtek "FE Series" driver that Speccy shows is for 10/100 speed ethernet chipsets too, so I'd say with 95-99% confidence it's a 100 megabit capable interface and not gigabit.
With internet connections faster is always good, but I'd say the really fast 100mbit+ services are really only going to come into their own when you have multiple devices connected.
