Is it possible for a wifi router to work without modem?
Of course it will work without a modem.The router will provide a wifi connection to your devices, and provide them all IP addresses. You can send files from one computer to another, stream a video stored on your phone to your tv or chromecast, and can print files just fine.What it will not do is provide you with an internet connection.The internet connection comes from your ISP, since it is not feasible to send data over ethernet wires over long distance you need a modem, or more correctly termed a ‘media converter” to convert the medium they provide (cable, phone for dsl, 4g cellular signal, or fiber) into ethernet (or usb) that your router/computer can use.There is an unfortunately too common of a misconception that WiFi and Internet are the same thing and are completely interchangeable words.WiFi = a communication protocol and standard that allows a device to join a computer network without needing a physical hard wired connnection.Internet = a connection from your local home network (all the devices connected to wifi and lan ports of your router) to other networks. The internet is just a collection of other people’s computers/routers/web servers.The internet and the connection to it existed well over a decade before the WiFi protocols where commercialized.
How fast is 25 Mbps internet?
25 Mbps is the minimum broadband speed as defined by the FCC.25 Mbps may be adequate for a single user or multiple users with light use.Remember, Internet bandwidth is shared.The more users and devices that you have, the more Internet speed you will require.Many people would likely be surprised at how many active connections their router has. I have dozens. cell phones, tablets, iPods, game consoles, laptops, desktops, ROKU boxes, Internet enabled devices such as TVs and audio receivers, Amazon echo and smart-home devices and the list goes on.Demands are increasing, streaming a 4K movie from Netflix could eat up all of a 25 Mbps connection. Here are Netflix minimum connection speed recommendations.I have multiple TVs and had previous buffering issues when simultaneously streaming even with a 100 Mbps connection.I have since upgraded to Cox Gigablast Internet, which solved any Internet bandwidth problems.That being said,You could be happy with 25 Mbps, just a few years ago 25 Mbps was considered very fast, and in some areas still is.For general browsing, game playing and streaming, you’ll likely be fine. However, multiple HD video streaming, many simultaneous users, etc. may stress a 25 Mbps Internet connection.If your 25 Mbps speed is not sufficient, the only real way to speed up your Internet connection is to get a faster ISP or speed tier.First contact your existing ISP and see if they offer a faster Internet plan and what kind of deal they will offer if you threaten to switch providers.If they don’t offer a faster plan, or the price is too high, then it will depend on what Internet providers are available in your specific area and what levels of service they offer in that location.To compare speed and prices of your local competitors, go to a ISP comparison site that lets you input your address, and compare the pricing and terms of the offers that are available in your area. In the US you can use this one , otherwise do a search for "ISP comparison" at your favorite search engine.You'll want to pick the fastest plan that fits your budget. In some areas this can be 1000 Mbps+. But these high end broadband plans can be expensive. You may find that something in the 50 to 150 Mbps range might satisfy your needs at a much lower cost.Good Luck...
