Change your laptop settings to prioritize 5GHz Wi-Fi.
Hi there, you're looking to restrict your laptop to only use the 5GHz band of your router. Since your Dell XPS 15 9560 uses an Intel ac8265 card and the ZTE h2640 is dual-band, you might need to adjust the router settings or consider firmware updates. Check if your router supports strict 5GHz enforcement and see if changing its Band Steering mode helps. Also, ensure your laptop's network adapter is set to prioritize the 5GHz channel. If the issue persists, contacting ZTE support for your specific model could provide further guidance. Let me know if you need more details!
With an Ethernet cable, you might begin by checking the connection and see if hardwiring resolves the stuttering, just as a test would. If successful, you may need to configure your router to broadcast two SSIDs—one on the 2.4GHz band and one on the 5GHz band.
I already checked that and didn’t mention it. Ethernet performs flawlessly without any lag. When I’m back home, I’ll adjust the router’s settings—probably creating a dedicated guest network, which shouldn’t interfere with the primary connection.
I turned off the 2.4GHz radio on my router completely. There are no devices needing it, and they’re all near the router, so 5GHz works perfectly. That could be a viable option.
Ensure each network is assigned a unique frequency channel. The router might handle this automatically. Ideally, your router supports separate 2.4 GHz and 5 GHz networks. In Windows settings, disable any existing connections to that router. Switch to the 5 GHz network and enable auto-connect. This should resolve the issue.
At the router setting... Assign distinct SSIDs for 2.4GHz and 5GHz, such as MyWiFi_2G and MyWiFi_5G. If your router supports adjusting antenna power, boost the 5GHz output and reduce the 2.4GHz signal. For smaller spaces with clear 5GHz coverage, turn off the 2.4GHz broadcast. On the client side... Join the 5GHz network you configured (optional automatic mode) and turn off automatic joining for 2.4GHz. Adjust adapter preferences to favor 5GHz and set moderate roaming behavior. If using 5GHz, ensure there’s no obstruction or distance causing issues; otherwise, interference from nearby networks may be the cause. You might need to perform a wireless scan and fine-tune your channel to avoid signal clashes.
You could skip using the 2.4GHz port on the gadget (to avoid unexpected switches) and/or adjust the network settings to rank the 5GHz option above the 2.4GHz one, making it the preferred choice.
I avoided the 2.4GHz frequency since 5GHz can't reach some areas of the house. Following Falcon's advice worked mostly well now—just occasional glitches remain, not as frequent or intense as before.
