Hi guys when I am at home I like to play mobile games,and I don’t use my wifi because so many people are sharing and it’s very laggy.Whenever I play the game,it’s kind of unstable and laggy or delay,but my mobile 4G is showing full bar.I am playing inside my room though,is it that mobile data is really not good for gaming or is it the game server problem??I am playing a game by konami

Mobile data is not suitable for low latency gaming experience...
even Wifi is not 100% stable for gaming...

4G for general use is already unstable and yet u using it for gaming? Sure worse la!

Using 4g alone adds around 40ms latency at its ideal condition. This is on top of routing and local hardware latency and also increased packet loss as well cell congestion.

But cannot adjust 3G,only 4G on mobile data and 5G haven’t come to maxis yet…I am not playing on my wifi,because it’s so unstable when other family member stream Netflix or YouTube,lag like shit

What plan and isp u are using?
If using fibre internet,then mostly the problem is on the router end.
(If using unifi,u might want to change your router 1st and if the wifi router signal low or distance too far use mesh to extend your wifi)

change to u mobile. maxis data is absolutely crap since a few months ago.

Wifi situation can be improved somewhat with QoS. Especially useful when you are on baseline plan like 30mbps. The result depends on router and qos mode selected. Doesn't magically make your internet faster, but it does make it apparently faster where it matters the most.
