Got question lah:

I use Maxis coporate plan with 21mbps mifi modem. My area , setapak have high Ping and lots of packet lost. Cannot play online games.

Downloads can reach max 4-5 mbps during non- peak hours (but not stable, got packet lost) . But 7pm -12am, browse also cant

Signal i get -60dBm, HSPA+ .

I know it maybe congestion problem, but u think change LTE modem or add antenna or DIY parabolic dish would make it better?
