Airtel V-Fiber (VDSL) - Link Drop & Other Issues [HELP]

[Abhi1136]

the airtel guy came and replaced the Huawei 630 router with binatone dt 920w. speeds are fine but my mobile is not getting connected to wi fi?

 

[Sushubh]

maybe he created a different wireless password on the new device?

My Huawei was replaced with a binatone 920w as well but i noticed a peculiar problem with it. Even though the vdsl link itself was stable with no resyncs, after about a day or so of uptime there would be heavy packet loss and only a restart would fix it and the cycle would repeat itself. So, I got them to replace the binatone with a D-Link dsl 224 and it worked well for 3-4 days but today after approx 2 days of uptime there was packet loss again (20-25%) and upon checking the dsl stats i noticed the CRC errors count rapidly increasing and as was the case with binatone, it became normal after a router reboot. I don't know what to make of it because i never faced this problem with the huawei .

@waterloo_sunset Your stats don't seem good for a stable VDSL connection. They are still good for an ADSL+ profile. As per the Airtel guy who came to Install, the min SNR in VDSL should be more than 12db for average to good connection and 15+ for excellent stability. However, on ADSL the SNR can go as low as 7db and still remain somewhat stable for 16mbps profile.

Guys ,
I am on 40 Mbps Connection (From Lucknow) and my speed keeps on Fluctuating during the day.Its only during the late night OR early morning I get 40+ Mbps speed..I have complained innumerable number of times.They have even changed my wires and got some sort of testing done but still no improvement.During the day speed keeps on fluctuating between 10-35 Mbps.It's very annoying.

Can anything be done regarding this.

Here are my stats:

@yougotmehere I'm aware that the line stats are not ideal but the only thing that's changed is the router. The connection was trouble free for 9 months with the Huawei.

Facing random disconnections for the past 2 days and getting only 3 mbps downstream.
No reply from Airtel yet after my complaint

Because Huawei has the best hardware chips among the three routers and it still can hold on steady till the last breath unlike others. I am not sure if those modems will ever come back as homemade (Binatone) routers are in circulation. Might wanna try bribing some service engineer to get you the Huawei one.

@raj2007 Check with your local service engineer as he can tell you in a sec. Usually they downscale the sync rates when their is some upgradation in the process or some kind of breakage or even a server glitch (My profile got corrupt at the server end and sync rates got randomly assigned)
