GoKawiilUSB wireless dongles found to degrade Wi-Fi by crowding 2.4GHz band
Many wireless peripherals, such as USB dongles for mice and keyboards, operate on the 2.4GHz radio frequency, a congested band also used by microwave ovens and older Wi-Fi gear. This overcrowding can interfere with Wi-Fi signals and slow down networks, especially for routers that are not running exclusively on the less crowded 5GHz or 6GHz bands used by Wi-Fi 6E and 7.
GoKawiil's interpretation of the reporting above, not reported fact.
The explanation suggests that poor Wi-Fi performance may not always stem from an internet provider's network but from interference created by a user's own desk setup. It also highlights a tradeoff in newer Wi-Fi standards: faster 5GHz and 6GHz bands offer less interference but weaker range through walls, which can push devices back onto the crowded 2.4GHz band and undercut the benefits of upgrading hardware.
- Most USB wireless peripherals use the crowded 2.4GHz frequency, shared with microwaves and older devices.
- Wi-Fi 6E and Wi-Fi 7 networks using 5GHz/6GHz bands face range limitations that can force fallback to 2.4GHz.
- Reducing nearby 2.4GHz wireless gadgets could help improve Wi-Fi speeds without contacting an internet provider.
TP-Link Archer AXE75 Wi-Fi 6E Router — If your 2.4GHz band is a crowded mess of USB dongles and smart gadgets, a tri-band router with 6GHz support gives your devices a clean, uncongested lane to connect through. The Archer AXE75 supports Wi-Fi 6E, letting newer devices skip the noisy 2.4GHz free-for-all entirely while still offering solid range on the other bands. It's a practical upgrade for exactly the interference problem described in the article.
