Airtel V-Fiber Modem

Airtel provides Huawei Home Gateway HG630a router/modem for v-fiber. Airtel charges Rs 1000 for this modem (billed at Rs 200/month in 5 installments).

Unlike the other A-DSL routers/modems, you cannot directly login into the web console of this router/modem. So in case you want to set different password for your WiFi or change your SSID, you need to contact Airtel customer care. Airtel would send you a one time password, using which you can set your WiFi SSID & password at http://setup.airtelbroadband.in/


But then you can work around this WiFi setup limitation by connecting Huawei modem to your own WiFi router.

Airtel V-Fiber Speed test

I let the speed test image do all the talking..



How to get it?

Visit Airtel V-Fiber site & provide your details. They would call you back for upgrade.

What they change?

Just the modem. They will replace old A-DSL modem with the newer model. No change in the wiring at-all. The newer modem has built-in Wi-Fi as well. Remember, you also need to get new A-DSL splitter. Airtel does not provide the same.

How much does it cost?

Airtel charges 1,000 Rs for the modem. Airtel charges this to your monthly bill via 5 monthly installments (200 Rs each moth). Also the new splitter costs about 280 Rs.

What about the monthly plan?

No changes in your monthly broadband plan. My current plan is 1399 Rs for 100GB.

Is it worth it?

Absolutely! Go get it..

Reviving your dead phone

Disclaimer: There is high possibility that below mentioned steps may not revive your phone. I am not responsible if below steps does not work for you.

One day, all of sudden my Samsung Galaxy Note (N-7000) was dead. I tried everything to switch it on but nothing worked. I tried removing & putting the battery back on. I tried new battery. I tried new charger. Nothing would switch-on the display of the phone.

I was about to take the phone to Samsung service center, assuming that phone charging circuit is blown out. Then suddenly I got a thought of removing micro-SD card of the phone & checking if it does any miracle. I remove the micro-SD card from phone, put the battery back-on & try switching it on.. voila, phone finally switched on!!

I quickly backed up all the data from phone, switched it off & put back the micro SD card. Even after inserting the micro-SD card, phone continued to work (I later quickly exchanged the phone in Flipkart Winking smile).

So if your phone to seems to be dead & then try to remove micro-SD card & switching it on again. It may be a worth a shot.

Lessons Learnt: Always back up your phone data. You can never trust any electronic devices  Smile
