None of the JioFiber ONTs are best. Every model has it's own Pros and Cons. Among them, JCOW414 was the last launched one and that was launched around 2-3 years ago.
You need to get your own router (preferably a TP Link model) and connect it to JioFiber ONT via LAN cable to get the best results.
And yes, JioFiber ONT and STB will come as refurbished only now since they are not manufacturing new ones and recycling the returned products from canceled customers.
Their investment is only towards AirFiber now (I know that's not what we (the customers) want!).
Thanks for your insights regarding the JioFiber ONT models and the suggestion to use a separate router for optimal performance. While I appreciate the recommendation to use a TP-Link router, I would like to discuss the specific issues I have encountered with the refurbished Jio router provided with my JioFiber connection.
Unfortunately, the refurbished router I received has proven to be completely damaged. Since the installation of my JioFiber connection three weeks ago, I have already replaced the router twice due to severe issues. The first replacement router was dead(JCOW411) on arrival, and the second(JCOW414) replacement exhibited significantly poor latency performance and coverage issue, which is crucial for my gaming needs.
Reflecting on past experiences with Jio routers, I recall that JCOW4032 model, which I used six years ago, provided excellent coverage and performance. However, it is now outdated, prompting my search for a suitable alternative.
Specifically, I am interested in your opinion regarding the JCOW407 model. I have heard mixed reviews about the JCOW414 model, with reported issues related to latency and coverage. I am curious to know if the coverage issue is widespread across all JCOW414 models or if it is specific to my refurbished router.
Additionally, I have heard some concerns about heat issues with the JCOW411 model. Given this background, I would greatly appreciate your insights on whether the JCOW407 model might be a suitable option for my requirements. I am particularly concerned about latency, as there have been instances where the latency has exceeded 350ms, impacting my gaming experience significantly.
