How did we come up with the list, you ask? How did we create this buying guide?

  • First, our algorithms collected as much information available about these products from trusted sources.
  • We employed both Artificial Intelligence and large data volume to validate all collected information.
  • Then our AI ranked them on their quality-to-price ratio using industry-standard criteria that let us pick the best Modem For 400 Mbps currently on the market!
The products aren’t chosen randomly. We consider several criteria before assembling a list. Some of the criteria are discussed below-

  1. Brand Value: What happens when you go for a not-so-reputable brand just because the price seems cheap? Well, the chance of getting a short-lasting product goes higher. That’s because the renowned brands have a reputation to maintain, others don’t.


Top Modem For 400 Mbps brands try to offer some unique features that make them stand out in the crowd. Thus hopefully, you’ll find one ideal product or another in our list.

  1. Features: You don’t need heaps of features, but useful ones. We look at the features that matter and choose the top Modem For 400 Mbps based on that.
  2. Specifications: Numbers always help you measure the quality of a product in a quantitative way. We try to find products of higher specifications, but with the right balance.
  3. Customer Ratings: The hundreds of customers using the Modem For 400 Mbps before you won’t say wrong, would they? Better ratings mean better service experienced by a good number of people.
  4. Customer Reviews: Like ratings, customer reviews give you actual and trustworthy information, coming from real-world consumers about the Modem For 400 Mbps they used.
  5. Seller Rank: Now, this is interesting! You don’t just need a good Modem For 400 Mbps, you need a product that is trendy and growing in sales. It serves two objectives. Firstly, the growing number of users indicates the product is good. Secondly, the manufacturers will hopefully provide better quality and after-sales service because of that growing number.
  6. Value For The Money: They say you get what you pay for. Cheap isn’t always good. But that doesn’t mean splashing tons of money on a flashy but underserving product is good either. We try to measure how much value for the money you can get from your Modem For 400 Mbps before putting them on the list.
  7. Durability: Durability and reliability go hand to hand. A robust and durable Modem For 400 Mbps will serve you for months and years to come.
  8. Availability: Products come and go, new products take the place of the old ones. Probably some new features were added, some necessary modifications were done. What’s the point of using a supposedly good Modem For 400 Mbps if that’s no longer continued by the manufacturer? We try to feature products that are up-to-date and sold by at least one reliable seller, if not several.
  9. Negative Ratings: Yes, we take that into consideration too! When we pick the top rated Modem For 400 Mbps on the market, the products that got mostly negative ratings get filtered and discarded.
These are the criteria we have chosen our Modem For 400 Mbps on. Does our process stop there? Heck, no! The most important thing that you should know about us is, we're always updating our website to provide timely and relevant information.
