We live in a house where 5-10 devices can be connected at any time.

When a specific laptop connects to the network, the whole network seems to degrade to either not working, or slower than a snails pace.

We've spent a few hours trying to debug this. Here's what we learned.

  • Wifi card on the laptop has a connection type of 802.11ax. Other devices are running on 802.11n.
    • Changing the connection type of said laptop to 802.11n does not do anything
  • We've enabled 5GHz and 2.4GHz on the router. However when the laptop is connected to 5GHz, and the other devices to 2.4GHz, the internet still isn't working.
  • We hotspotted another laptop (call it laptop B). When laptop A connects to laptop B hotspot, internet is working fine 👍. This isn't a good solution though as laptop A and B may not be in the house at the same time.

Laptop A is a HP Envy 15 with an Intel WiFi 6 AX201 wireless card. Our internet is mobile broadband, and the router is Huawei H122-373.

  • Try laptop A with another network card, to check if its own is broken in a way that monopolizes the router's bandwidth (unless throttled through a hotspot).

  • Does the laptop run a dhcp server or have a hard coded static IP address?

You need to disable Throughput Booster on the device that is booting the other devices off the network.
