I have Airtel Fiber 100 mbps plan. I mostly play games on my tab and whenever I play efootball with airtel fiber there is delay/lag which makes gaming experience bad. But when I play same game with Airtel 5g hotspot from my phone there is no or minimal lag/delay. Contrary to this, cloudflare/cloudping/other speed tests report better results for my airtel fiber as compared to 5g. Cloudflare reports gaming/streaming/video call as great but Its always poor/bad for Airtel 5g still game works better in 5g. Is it due to AOT-4221sr router? Can router be the issue behind this? I have optimised through airtel app too but still not solution. And sometimes twitter/insta loads very slow on wifi but no such problem on 5g.
