  2. Duplex mismatch - Wikipedia

    en.wikipedia.org/wiki/Duplex_mismatch

    Contrary to what one might reasonably expect, both sides of a connection need to be identically configured for proper operation. In other words, setting one side to automatic (either speed or duplex or both) and setting the other to be fixed (either speed or duplex or both) will likely result in either a speed mismatch, a duplex mismatch or both.

    en.wikipedia.org/wiki/TCP_tuning

    In computer networking, RWIN (TCP Receive Window) is the amount of data that a computer can accept without acknowledging the sender. If the sender has not received acknowledgement for the first packet it sent, it will stop and wait and if this wait exceeds a certain limit, it may even retransmit .

  4. Contention ratio - Wikipedia

    en.wikipedia.org/wiki/Contention_ratio

    In computer networking, the contention ratio is the ratio of the potential maximum demand to the actual bandwidth. The higher the contention ratio, the greater the number of users that may be trying to use the actual bandwidth at any one time and, therefore, the lower the effective bandwidth offered, especially at peak times.

  5. Autonegotiation - Wikipedia

    en.wikipedia.org/wiki/Autonegotiation

    Autonegotiation is a signaling mechanism and procedure used by Ethernet over twisted pair by which two connected devices choose common transmission parameters, such as speed, duplex mode, and flow control. In this process, the connected devices first share their capabilities regarding these parameters and then choose the highest-performance ...

    en.wikipedia.org/wiki/Amdahl's_law

    An implication of Amdahl's law is that to speed up real applications which have both serial and parallel portions, heterogeneous computing techniques are required. [12] There are novel speedup and energy consumption models based on a more general representation of heterogeneity, referred to as the normal form heterogeneity, that support a wide ...

    Check the physical connection - A loose cable or cord can often be the cause of a connection problem. Make sure everything is securely connected to the wall and device. 3. Reboot your modem/router - Sometimes the old "turn it off and on again" approach actually does work! Just wait about five minutes before turning it back on to make sure ...
