Jio is using

Deep packet inspection

Carrier-grade NAT

Poorly configured stateful IPv6

Almost completely locked down router with some non-sequitor options

Clueless customer service, who just say “we can’t talk about X or Y or Z” and who often do not even understand the question. If you ask about IPv6 settings, they’ll say they can’t help you, and then proceed to misinterpret it as a request for a static IP address.

The first two are reasons enough to not use this shitty ISP.

To explain in more detail:

Every bit of data transmitted on the internet is transmitted as a packet. Think of this packet as a matryoshka doll. What Jio does is open these dolls to see what the innermost dolls look like. That obliterates your privacy. Jio is using software that is good enough to deny you service even if you use strong encryption. I believe that heuristic analysis and the use of known signatures is a part of the firewall.

Before the days of IPv4 pool saturation, you would get a public IPv4 address (or even more than one) from your ISP, while your LAN would have a private IP address from a range reserved by the IETF (such as 192.168.×.x or 10.×.×.x). When these addresses became more scarce, ISPs moved to dynamic allocation, so unused addresses in their range would be recycled for other customers to use based on uptime. However, each customer still received a unique public IP address. Eventually, people decided that the principles used on large enterprise LANs could be applied to ISPs as well. On a service with CG-NAT, your public IP address is now shared with many other customers.

This is bad for several reasons, and performance and reliability are two of them. For instance, you could have trouble transmitting UDP packets across two routing tables. On a poorly configured network though, security is an even bigger concern, because you can expose multiple customer subnets to each other. The firewall on their router is a major cause for concern. The default is to allow all connections, rather than only established or related connections, while blocking others.

IPv6 was introduced with the aim of mitigating the shortage of network addresses, and to also reduce the workload on network infrastructure, by changing the way addresses are assigned. I will not get into too much detail as I am no expert on IPv6 networking and haven’t really messed around with it until I got Jio, but I can assure you that they are not following the guidelines or best practices for deploying IPv6.

For instance, WAN is assigned in a stateful manner, with only a /128 address being given to your router. Your LAN is by default configured to be stateless, with a /64 prefix length. However your LAN prefix is not assigned by the ISP, but is instead assigned from a reserved linked-local IPv6 range defined in an outdated RFC. So you literally get none of the benefits of IPv6, and all of the downsides of IPv4, as a NAT is involved in your connection.

Bridging mode is completely broken. You still need to configure your WAN interface even when you want to bridge the Jio router to your own equipment.

Jio’s customer service is brain-dead retarded, and will simply refuse to help if you want anything more than basic troubleshooting. They also don’t have any L2 or higher technicians available on the phone. Also, the best part is that their TSP and ISP divisions are separate, yet they seem to use the same customer care number! God help you if you call from your registered mobile number, because then you will be quickly connected to a human from one department, who will promptly refuse to look at issues involving the other department, and you will completely fail to connect to that particular department. They won’t even transfer your call! Also when you use a non-registered number to get around this and provide them your registered mobile number, they have no means of identifying which service tickets belong to which department.

When I raised a complaint with the fiber department, and then called the jiofi department to register a separate complaint, the jiofi team would insist that the ticket was raised for jiofi, and when I raised a ticket with the jiofi team, the fiber team would insist that the ticket was raised for fiber!

I will admit that I am still using the JioFi connection, but that is because I paid for a year of service, and that only gets used for things like netflix and amazon prime when I am on the move. It’s not ideal, but I’m kinda stuck with that one.
