I am very interested in the IdeaCentre Q180.
Does the Ideacentre Q180 wired network support jumbo frames?
The Q180 should support Jumbo Frames based on its use of the Realtek ATL8111e Gigabit Ethernet controller as noted in the spec sheet on the Lenovo web site. A cross reference to Realtek's ATL8111e spec sheet confirms Jumbo frame capability - up to 9,000 bytes of payload per frame.
Please note that other components in the network chain including the DSL / Cable modem and interconnected Wireless routers must also be capable. Specific configuration changes and compatibility with other devices connected within the subnet may impose limitations.
