    Try the following with TCP Optimizer:

    General Settings tab:
    Custom settings - check
    Modify All Network Adapters - check
    network adapter selection - your NIC
    MTU 1500
    TTL - 64
    TCP Receive Window - 128480
    MTU Discovery - Yes
    Black Hole Detect - No
    Selective Acks - Yes
    Max Duplicate ACKs - 2
    TCP 1323 Options:
    Windows Scaling - checked
    Timestamps - uncheck

    Advanced Settings tab:
    Max Connections per Server - 10
    Max Connections per 1.0 Server - 20
    LocalPriority - 1
    Host Priority - 1
    DNSPriority - 1
    NetbtPriority - 1
    Lan Browsing speedup - optimized
    QoS: NonBestEffortLimit - 0
    ToS: DisableUserTOSSetting - 0
    ToS: DefaultTOSValue - 80
    MaxNegativeCacheTtl - 0
    NetFailureCacheTime - 0
    NegativeSOACache Time - 0
    LAN Request Buffer Size - 32768
    Then select "Apply Changes" and reboot to take effect

    The ping times at hop 1 of both tracerts show relatively high values. Normal value would all be <1ms.

    Either you have a long cable connected to the router, or it is being placed in a location of strong electromagnetic interference.
