Help Globe at Home Xtreme Full Signal Pero napakabagal How to fix?

[fgzEr01]

Medyo kakabili lang ng globe at home na white malakas signal nya dito sa area namin pero sobra bagal at baba kapag nag speed test pinakamataas na ata ay 8mbps tsambahan payan nasa 2 mbps lang sya stable at nakaregister ako ng regular na data ganyan pa din. May way kaya para mafix to? feeling ko may speed limiter yung router.
