A frame is a single unit of transportation on the Data Link Layer. It consists of header data, plus data that was passed down from the Network Layer, plus sometimes trailer data. An Ethernet frame has an MTU of bytes, but the actual size of the frame can be up to bytes byte header, 4-byte CRC trailer.
Common failure indications include the following:. If you are not experiencing a problem, do not change the MTU value. Usually, an MTU value of works.

Another trick that has worked in the past is disabling the ICS service in the services. You can also try using windows compatibility mode.

Oh yeah Hope this helps somebody! Tuesday, July 28, AM. Thanks - I have a Lenovo xs - did all the same steps - tried many client versions now 5.
