If there are multiple users trying to perform certain high-bandwidth activities at the same time—streaming HD video for example—then the 2.
To provide faster speeds, and limit the impact of interference from other devices, manufacturers added support for the 5 GHz frequency in the latest generation of WiFi routers. With two frequencies bands available, these dual-band routers can handle much more traffic.
The 5 GHz band also has many more channels than the 2. Like the 2. Dual-band routers support both the 2. In most cases, the device you are using to connect to WiFi, such as your laptop or smart phone, chooses the band. For example, your brand new phone might stay on the 2. It will only switch to the 5 GHz band if you tell it to or if it can no longer connect to the 2.
These standards are basically rule books that make sure routers and online devices are on the same page, ensuring that your Roku plays just as nicely with your router as your tablet does. A single-band router is limited to, as you might've guessed, just one frequency band—the 2. Older, single-band routers operate on the The iPhone 3G and 3Gs use this standard, for instance.
More likely, though, a single-band router operates on the somewhat newer Though single-band, 2. It breaks down something like this:. In addition to supporting the 2. At their theoretical best, that means they support aggregate speeds up to 2, Mbps or more. For most households, 5 GHz connectivity is what makes these routers really shine. Imagine that the 2. Having been around for more than a decade, there are a whole lot of 2. This is especially crucial if you live in a well-populated city or a big apartment building.
If both bands of wifi are being broadcast under one single name, a few devices will let you manually choose 2. The good news is that means less for you to worry about—just carry on using your wifi and your router and connected devices will take care of switching between 2. The downside is less manual control over your network, and fewer troubleshooting options should something go wrong.
While most routers now automatically combine the two bands under a single name you can usually turn this feature off in the settings allowing you to choose which band your devices connect to. If you find your router is being stupid and connecting devices to the less optimal band this is an easy fix—though it does make things more complicated for guests looking to borrow your wifi.
It never even crossed my mind when my recent IPS gave me access to both bands. Is there a list somewhere about which devices benefit the most from which band? Or is the optimization not that significant?
