ask high ping/ latency for bypassed(IP binding) client

My setting is using hospot only by default , everything is working fine

only ping/ latency cases from client perspective

  1. if using login page/ hotspot, ping is small(28ms)
  2. mac/ IP set/ place to bypassed(hotspot IP bindings bypassed; without hotspot login portal) its ping/ latency is jump/ gets to higher value(123ms)
    (tried cookies, host table are cleared before make IP binding or stay as is result higher ping)
    no other firewall filter rules, anyone seeing these?..

how to fixing these for the bypassed client to get atleast from high latency/ ping time(~123) would be similar to the one has login portal(~28ms)
or what rules to makes?

Thank you very much
