Fortunately, there are many reliable public DNS servers known for their speed and reliability, including Google Public DNS and Open DNS. If the DNS servers used by your ISP are far away or overloaded, you'll likely notice poorer internet speeds overall.

Using your ISP's default DNS servers might be slowing down your downloads. If there's no way to minimize obstructions, switching to 2.4 GHz can improve your download speeds.

Physical obstructions, including walls, tall furniture, and glass from mirrors and windows can also interfere with your connection to the Wi-Fi router, especially if you're using 5 GHz.

And, if you live in an apartment or condo, your neighbors' Wi-Fi connections can overcrowd 2.4 GHz bands.

2.4 GHz is more vulnerable to interference than 5 GHz, such as from microwaves, baby monitors, garage door openers, and security cameras.

So, if your computer can be in the same room as your Wi-Fi access point, switching to 5 GHz will improve speeds.

While you'll get better wireless coverage using 2.4 GHz Wi-Fi in your home or office at further distances, your data transfer speeds will be lower than with 5 GHz.

X Research source If your router supports both frequencies, switching to the other might benefit you. 2.4 GHz Wi-Fi travels a farther distance at lower speeds, while 5 GHz provide faster speeds at shorter ranges. It may be beneficial to switch Wi-Fi frequencies depending on your home or office layout.
