Kerala Vision Broadband FTTH - User Experience

@Massivesiege There shouldn't be an issue with that ONT, should work okay bridged as a dumb modem / ONT.

However I'm not sure if it would be available for that price considering the shortage due to Covid19.

If you are interested in a Huawei HG8120C (1GE, 1FE and 1TEL, works in both GPON and EPON mode), please PM me.

@varkey I can't seem to figure out how to send a private message on this forum,i will confirm with the lco if i can use a bridged ont with there olt and get back to you
thanks for the offer

New members can't start a private conversation, I've sent a message. 😅

Did anyone try this
Rs. 1,394.90 | Original hua wei single model SFP module single SC port PTXM167-431 B+I Module for GPON ONU FiberCore


The price and shipping makes economic sense for me to order and give it a try and it would arrive fairly soon as special line is gati and speed post for the last mile also since package is so small will be exempt from tax if i can convince seller to declare a commercial value of 200rs and cif of thr same amount

@Massivesiege Doesn't seem to have free shipping to India?

Also, Special Line Yanwen is no longer through Gati, it's being sent via Malaysia Post Registered. Comes in about 20-30 days. I've got couple of packages recently. There shouldn't be any duty though if the seller marks it for less than 10 USD or so.

From my tiny research a while back (and I could be completely wrong too), the Huawei GPON SFP modules can only be managed through the OLT, there is no web UI or any management options. If your LCO validates ONT serial number etc, you wouldn't be able to clone it like you'd do for other ONTs, and you would need to get them to whitelist the SFP module's serial.
It's definitely worth a try though, I'd have tried if I already had a SFP supported switch or router 😅

@varkey For some reason i thought I saw it being shipped via special line yt maybe I saw what I wanted to see


all the Netlink modems which the lco has no issues recommending seem to be out of stock on the website and lco wants to sell a genexsis ont with wifi for 2750 Rs which I don't want as I would be paying for stuff that I wouldn't even be using

Anyone tried the ZTE modem f601 ? As this seems to be cheapest now that netlink isn't selling anything anymore

Hi all,
I am new to this forum. In my area Varapetty in Kothamangalam, Ernakulam district, we have KeralaVision. LCO dont support BSNL ( thats what he said)
I opted for KeralaVision 60Mbps and the speed is very good except some pressing issues below.

1. Disconnects 10 - 15 times for short times during the day.
2. Less often during night.
3. I am in work from home mode and I loose my SSH connection many times due to this. (broken pipe)
4. I also connect to my work servers via ZeroTier and issues aside from ZeroTier which is a bit sluggish to recognize routes, it also seems to be slow on KeralaVision. Does KV have a thing against VPN tunnels ?

I have a Jio HotSpot device as backup and everything seems to work normal when using hotspot which gives max 6Mbps in my area.

But things are not good with KV which gives 60Mbps, I see latency of 250ms to ping google and 100% loss during continuous pings at random times during day & night.
I do not see LOS light in the modem during these times at all.

What else might be the problem then ?

I am using Netlink HG323RGW GPON ONT device.
Is there a latest firmware upgrade I can download ?
My local operator is PPPoE.
Is my default MTU of 1492 ok ?
Please see attached screenshot of Optical Tx/Rx power and firmware version.

@netcat99 A firmware update should fix it , disconnects stopped happening for me when i kept the ont in bridge mode and started using a router .

Thanks for the reply. What fixed my disconnects was downgrading the firmware.. I was on the latest and greatest firmware. I downgraded to 1.0.29-200319 and it seems to have fixed the problem. Now no more disconnects and I am happy with Keralavision for now 🙂

Hey guys,

At the end of the plan cycle, does the internet disconnect when it hits 12 AM post 30th day or at the exact time when we last recharged, i.e. 6.59 AM on the 31st day?

Can someone help me. I'm new to networking and I would like to switch my Netlink modem from route to bridge mode so that I can use my router (TP-Link Archer C6) for routing. Currently using my router in access point mode. It would be helpful if someone can provide a step by step guide. Thanks

@aKrRaC , If the connection is KV , I guess either your LCO has to register the mac address of your C6 or you will have to clone the mac of existing Netlink ONT to C6. I would suggest you should go with second method.

Then change the Internet profile type to Bridge in Netlink , bind the port to LAN2. Connect C6's WAN port to Netlink's LAN2 and provide the KV username and password as shown in the fig.

Try to dial the connection , if it succeeds , you are all set , now you may disable the WiFi in NetLink and enjoy C6's Wifi.

@vu3knb Can u help me in cloning the mac Id of my ont into the archer c6 . I cannot find the options to do it
