Neither higher nor lower is universally better; it depends on your needs: lower frequencies (like 2.4GHz) offer longer range and better wall penetration but slower speeds and more interference, ideal for basic use/distance, while higher frequencies (5GHz, 6GHz) provide faster speeds and less congestion for gaming/streaming but shorter range and poorer obstacle penetration, requiring devices closer to the router. For channel selection within a band, a higher channel number might avoid congestion with neighbors, but the frequency band itself (2.4 vs 5 vs 6 GHz) has a bigger impact.
If you want better range, use 2.4 GHz. If you need higher performance or speed, use the 5GHz band. The 5GHz band, which is the newer of the two, has the potential to cut through network clutter and interference to maximize network performance. Which means this band will be better for things like reducing game lag.
Lower frequencies are better able to penetrate materials. But the difference between high and low channels within each band is probably slight to non-existent.
2.4Ghz networks have two options: 20MHz (the 'normal' bandwidth) and 40MHz (doubled). It is HIGHLY recommended that you only use 20MHz-wide channels, as using a 40MHz channel will overlap with others, causing a decrease in performance or, generally speaking, troubles.
For 2.4Ghz channel selection, consider Channel 1 first, followed by 6 and then 11. But, most importantly, choose what has the least amount of neighboring networks on. In rare cases if all three of those channels are very slow, you may be better choosing an in betwee channel such as Channel 8 or Channel 3.
Yes, 5GHz Wi-Fi can go through walls, but its range and ability to penetrate walls are generally less effective compared to 2.4GHz Wi-Fi.
On the 2.4 GHz band, which is usually Wireless-N, always choose Channels 1, 11, or 6. Try to pick the emptiest of the three, using the Wi-Fi Analyzer as your guide. Channels other than 1, 11, or 6 will receive more interference.
For gaming on 5GHz WiFi, a 40MHz channel width offers a good balance of speed and low interference and that's what we usually recommend.
Bonding channels increase throughput, which can improve performance. Thus, the difference between 20 MHz and 40 MHz is throughput. 40 MHz has higher throughput than 20 MHz thanks to channel bonding.
If you're able to use most of your devices near your router, 5 GHz is your best choice to take advantage of higher speeds. Similarly, if you're doing a lot of high-bandwidth activities online, such as gaming or videoconferencing, it's best to use this frequency and move as close as possible to the router.
On the 2.4ghz band, you can connect up to 11 devices depending on the bandwidth usage of the device. However, each device can use different amounts of bandwidth so we don't advise connecting 11 devices at once as speed and performance can suffer. This is the band for speed.
In general, 36, 40, 44, and 48 are the best 5G channels WiFi because they are least likely to overlap with other channels. However, if these channels are already congested in your area, you can try using channels 149, 153, 157, and 161 as they are also less likely to overlap with other channels.
To get the most out of film night in your living room on your 4K Ultra HD Smart TV, the 5GHz option will make it smooth and buffer-free. But if you're watching from a bedroom in the far corner of the house, 2.4GHz will be more stable (though it might pixelate from time to time).
10 tips to help improve your wireless network
For gaming, home theater, and home office applications that depend on a lot of voice and video calls, using the 5 GHz and 6 GHz bands is recommended. 2.4 GHz is the “best effort” network for Wi-Fi, ideal for sending small amounts of data over longer distances.
Within each Wi-Fi frequency band is a set of smaller bands, each having a set width; these are the Wi-Fi channels. The right channels will provide faster internet speeds, as other channels can become congested due to traffic.
Each frequency band has its advantages for use with dual-band routers, tri-band routers, and the latest quad-band routers.
What are the best Wi-Fi channels for 5 GHz Wi-Fi? Use channels 36, 40, 44, and 48 on the lower 5 GHz band. Use channels 149, 153, 157, and 161 on the upper 5 GHz band.
Gaming and Content Creation: Aim for 3200 MHz or higher (DDR4) or 4800–5600 MHz (DDR5) kits. For DDR4 gaming rigs, 3000–3600 MHz is a sweet spot – it offers good performance without extreme cost. Many gaming PCs come with DDR4-3200 or -3600 by default.
A good rule of thumb is that download speeds of at least 100 Mbps and upload speeds of 10 Mbps are widely considered fast enough to handle nearly any online activity.
As a dedicated connection, 300 Mbps can provide a good internet speed for a gaming device, especially if connected via an ethernet cable. However, if there are multiple devices and users connected at the same time, you could possibly experience some lag and higher ping.
Wi-Fi 7 implements 4K-QAM (Quadrature Amplitude Modulation), a significant upgrade from the 1024-QAM used in Wi-Fi 6E. This technical improvement allows more data to be packed into each transmission, boosting theoretical data rates by about 20%.
In crowded areas with a lot of frequency noise and interference, a single 20MHz channel will be more stable. 40MHz channel width allows for greater speed and faster transfer rates but it does not perform as well in crowded areas.
