I recently bought an HP OmniBook 3 14-inch laptop with a Qualcomm FastConnect 6900 wireless adapter. It connects to my home network, but usually reaches less than 15 Mbps, while other devices in the same house get around 400–700 Mbps. The laptop works normally on networks at work and at other homes. Strangely, moving two floors away from my router increases its speed to roughly 200 Mbps, while connecting near the router is consistently very slow. My internet service uses Spectrum, with a separate modem and router, and the laptop appears to be connected over the 6 GHz band when the speeds are low.

First check which Wi‑Fi band the laptop is actually using when the slowdown happens: 2.4 GHz, 5 GHz, or 6 GHz. Windows may show this in the network properties, and you can also run `netsh wlan show interfaces` in Command Prompt. Since the Qualcomm FastConnect 6900 supports 6 GHz, the issue may be specific to the router’s 6 GHz connection or configuration. As a test, temporarily connect the laptop to the router’s 5 GHz network or give the bands separate names and compare the speeds.
Windows network properties show 6 GHz, and `netsh wlan show interfaces` reports the same band when the connection is slow.
