Update :-

Connected my Excitel router with JioAirfibre IDU

and here are the results -

@raj17 @Skye Seems Excitel hardware is also shitty but i confirm that JioAirfibre IDU is pretty rocksolid. There hardware is capable of handling speeds .

@invisible007 Honestly this result surprised me too 😅
In theory when an ONT is running in normal (router) mode(not AP MODE), you usually expect bad bufferbloat, higher jitter, and latency spikes because everything is handled by ISP hardware(Excitel ONT). But here the Jio AirFiber IDU is doing the opposite bufferbloat stays at A+ and latency barely moves under load.

That clearly shows the issue isn’t the line or ONU itself. The real problem comes from router side QOS management and Wi-Fi handling AND ALSO 6GHZ (JIO AIRFIBER ONT). With the Excitel router even though the ONU is fine the router struggles under load, causing high latency and jitter.

Also one important point was this test done on Wi-Fi or LAN?
Because Wi-Fi tests can vary based on interference and client capability, while LAN usually gives the real picture of router performance. Still even on Wi-Fi, this kind of bufferbloat difference is hard to ignore. but it pretty much confirms that Jio’s IDU hardware and QoS implementation are solid, while the Excitel router is the bottleneck.

One more suggestion I’d give you try using your own separate ONT instead of the Excitel crappy ONT because their ONT can also become a bottleneck.
Ask the technician or customer care for the GPON ID / Serial Number and GPON password.

Apart from that also confirm the VLAN ID used for the internet. In some areas you may also need PPPoE username and password (if Excitel is not using DHCP/IPoE). Without the correct VLAN the ONT may sync but the internet won’t work.

GPON ID + GPON password + VLAN ID is enough but it’s better to confirm all details before switching.
 
@raj17 yes these tests were performed on wifi

now here is the test done on LAN -

unloaded latency is always 5~6 ms , and Download active is stable 0~1 ms ..

BUT

i found a few drawbacks that i need to figure out , my samsung phone is not getting connected to this wifi but Redmi phone is getting connected .
one office laptop works , but home laptop is having issues. Iam unsure what changes are still needed in jio router or may be on excitel router.
 
@invisible007
Bro Those LAN results are honestly crazy good 6 ms latency with almost zero jitter +1 ms is basically what you’d expect from a local network. The problem isn’t the connection it’s pretty clear the stock Excitel ONT is the weak link here.
1. Security mismatch - Jio IDU often defaults to WPA3. Some older laptop Wi-Fi cards and even certain Samsung models don’t play nicely with it. Try switching the Wi-Fi security to WPA2-PSK AES in the Jio settings and see if those devices connect.
2. Band confusion 2.4 vs 5 GHz - maybe your device wont have 5 GHz band
