Internet connection is lagging at 2.4GHz frequency.
Internet connection is lagging at 2.4GHz frequency.
hey everyone, i hope you're doing well. i'm working in c++ and recently faced some internet issues. i have a 200Mbps connection via modem and router from my ISP, but it's been acting up lately. when trying to connect wired, i get 180Mbps, while wifi only gives 10Mbps even when close. after replacing the router with a tp-link dual-band model, i set it as a bridge and connected my tp-link as the main router. surprisingly, 5GHz gave me 140Mbps, but 2.4GHz was still very slow with poor range. i checked wifi analyzer and saw no signals on 2.4GHz, so maybe that's the issue. i'm unsure what to do next—should i replace the router or adjust settings? any advice would be greatly appreciated!
Additional gadgets may also disrupt the 2.4GHz signal. Key factors influencing interference include nearby devices. Microwave appliances Using a microwave near your laptop, Bluetooth gadget, or Wi-Fi router can lead to disruption. Direct Satellite Service (DSS) Coaxial cables and connectors in certain satellite dishes might generate interference. Inspect the wiring for wear that could emit radio frequency leakage; consider switching to new cables if needed. Power lines and electrical equipment Certain outside power sources such as utility lines, railway tracks, or substations can interfere. Keep your Wi-Fi hub, router, or Bluetooth device away from electrical wiring in walls or near circuit breakers. 2.4 GHz or 5 GHz phones Cordless phones operating in these bands may interfere with nearby wireless connections. Wireless video transmitters and audio systems also fall into this category. External screens and monitors Some displays produce harmonic noise particularly between channels 11 and 14 on the 2.4GHz spectrum. This effect can be amplified if you’re using a laptop with the lid up and an external monitor connected. Switching to a 5 GHz channel or a lower 2.4GHz frequency might help. Loose or damaged cables Poorly shielded cabling can cause signal loss. Devices like hard drives that use unshielded connections may affect performance. If turning off or moving the device resolves the issue, try replacing the connecting cable. Other wireless equipment Any other devices operating in the 2.4GHz or 5GHz range—such as microwaves, cameras, baby monitors, or neighboring Wi-Fi networks—can also disrupt your connections.
It’s better to try it with a different router as well to confirm whether the issue persists. Did you check speeds using multiple devices?
I noticed the 2.4 frequency and there are no signals from other routers around (the houses are close together). It might be something like a microwave or another device, but I don’t think so. This is my first time dealing with this issue, and there aren’t any wireless devices nearby in the house. My best option is to try purchasing another router and see if it works.
