Poor QOS on Airtel Broadband.

[nishantt6969]

I have two Airtel Fiber connections, both running on 300Mbps and both are from same Distribution Box (FAT box). The problem is unstable speed everytime I try do speedtest. Speed never really touches. Today I did speedtest starting at the same time on both routers, and their combined speeds equals to 300-320Mbps. There are already 3 connections from that FAT box except mine. How to get it fixed?
Help will be appreciated.

Upload speed is fine, always hitting 360+
Only issue is download speed.

It can be because of saturated bandwidth?

Have you tried resetting the Routers?

Also what's the power level on both routers?

Is it LAN or WiFi?

-20dbm, -21dbm.

I did reset multiple times.
Wi-Fi. But its kinda strange that every speed test upload shoots to 360+ whereas download doesnt.

It's wifi channel congestion issue.

My TP-Link Archer C6 does the same thing.
Upload goes up to 500+

But downloads are always 200-300 ish (300 Mbps plan).

But when Wifi 6 router is connected it shoots up to 600+ Mbps downloads & Uploads also.

Except replacing router or playing with different channels there's nothing much you can do.

replaced router 8 times.

Yea... no I don't think it's FAT Box issue. We have 20 airtel connections out of 1 fat box including 1 giga connection I.e., my neighbor. 1 fiber at all times will not be shared by more than 8 customers.
Likely poorly configured router at first ISP node or a bad policer.

anything which can be done by my side to fix this? @Lolita_Magnum

I tried speed testing again, issue remains same but I found out something. When one router is running at maximum speed offered(300Mbps), there is packet loss, ping breaks. It means our connection is shared and bandwidth is saturated?
