OK, I called up Airtel (at 198, didn't bother to mention any details to the call center people, they are morons anyway). The dude came within 1 hour of my complaint, which is surprising (I thought their customer service had gone to shit).Anyway, this dude is somewhat knowledgeable and mostly knows his stuff. He was able to navigate around
Mac OS X, and find Terminal.app where he ran a few ping tests.Obviously the issue is of random disconnects, and as fate would have it no disconnections occurred for the 30 minutes he was at my place.In the end, since I have my own
router, he blamed the issue on the router. And said that Airtel cannot provide support for third-party routers. I have
Linksys WAG54G2, which is a pretty decent router IMO, and I don't think the router is the issue.I also told him that a lot of other people are facing this issue. Specifically mentioned Sushubh's case who is living in Gurgaon. So I told him its not even a localized issue.Now, the thing to see is if this problem occurs in sync, that is if the outage occurs at the same time for everyone.So to anybody who is facing the same issue as us, I'd request you to sync your computer's clock with an Internet server (if you don't do that already) and please note down the exact time range at which the next outage/disconnection occurs. And then post the range(s) here. If it hits us simultaneously, at least we can have a case with Airtel that this issue is not on our end.He did not know anything about Airtel upgrading/modifying their backend.
