Best wifi dongle for strong range/coverage

When I had a look at the settings of the router it also had an option of 5Ghz. Can I use the 5Ghz for the one furthest away in the bedroom whilst the other closer devices continue to use 2.4ghz

Can anyone recommend a wifi dongle that they have found to have an improvement in a upstairs room or a room furthest away from their router?

The primary differences between the two frequencies are the range (coverage) and bandwidth (speed) that the bands provide. The 2.4 GHz band provides coverage at a longer range but transmits data at slower speeds. The 5 GHz band provides less coverage but transmits data at faster speeds.

The range is lower in the 5 GHz band because higher frequencies cannot penetrate solid objects, such as walls and floors. However, higher frequencies allow data to be transmitted faster than lower frequencies, so the 5 GHz band allows you to upload and download files faster.

Your WiFi connection on a particular frequency band can also be faster or slower because of interference from other devices. Many WiFi-enabled technologies and other household devices use the 2.4 GHz band, including microwaves and garage door openers. When multiple devices attempt to use the same radio space, overcrowding occurs. The 5 GHz band tends to have less overcrowding than the 2.4GHz band because fewer devices use it and because it has 23 channels for devices to use, while the 2.4GHz band has only 11 channels. The number of channels that are available to you depends on the regulatory domain. If you’re experiencing a lot of interference from other devices, consider using the 5 GHz band
