Airtel Xstream Broadband: Frequent Disconnection Problem

[nerdseeder]

Hi Guys,

I am seeing frequent/consistent disconnection. I am running pfsense with static IPv4 config in bridge mode. Disconnection are consistent. This started suddenly from last week. I am using 8.8.4.4 as gateway monitor IP.

I checked pfsense logs for any hardware issues. I tried plugging ethernet cable to different port but no luck even restarted both ONT and pfsene box. Raised this issue with Airtel customer care/appellate but no luck. I am not sure what is going on. I would appreciate any help.

Old ONT

Optical power levels?

 

[Rickysin]

Can you share the packet loss percentage just by pinging google dns for 10 minutes through command prompt ?
also are you on gigabit plan ?

 

[nerdseeder]

@Rickysin
Yeah I am on Gigabit plan with static IP. My gateway suddenly stops responding for any incoming or outgoing traffic. I am monitoring ping in both direction. Even my gateway stops responding to ping and things become to normal after 2-3 minutes. This is happening every 1 hour or 45 mins.

 

[nerdseeder]

ONT Optical power stats.

 

[Trex]

I am not airtel user but using BSNL fiber and having same issue as you.

 

[Rickysin]

ONT Optical power stats.

-24.2 power seems to be the culprit.
raise a ticket and ask local engineer to fix this. It should be -17 to -21 for good connection

 

[nerdseeder]

@Rickysin I asked them about optical power as per them it is fine.
