Frequently Asked Questions
Why is Wi-Fi 7 not connecting on Lenovo Slim 7 Gen 9?
The Lenovo Slim 7 Gen 9 has an Intel Wi-Fi 7 adapter, but it can fail to connect to a Wi-Fi 7 or 6E router if the driver is outdated, the 6GHz band is disabled, the router firmware is old, or regional 6GHz settings differ. It often falls back to slower bands instead.
How do I fix Wi-Fi 7 on Slim 7 Gen 9?
Update the Intel Wi-Fi driver from Lenovo Support for Slim 7 Gen 9, update the router firmware, ensure the 6GHz band is enabled on both the laptop adapter and the router, and confirm the router is set to a Wi-Fi 7 or WPA3 mode the adapter supports.
Does the 6GHz band need enabling on Slim 7 Gen 9?
Yes. Wi-Fi 7 and 6E use the 6GHz band, which must be enabled in the router settings and supported in your region. In the Intel Wi-Fi adapter Advanced settings, confirm 6GHz is not disabled so the Slim 7 Gen 9 can use the fastest band.
Why does the Slim 7 Gen 9 connect at Wi-Fi 6 speeds only?
If the laptop connects but only at Wi-Fi 6 speeds, the router may not be broadcasting 6GHz, or WPA3 security required for Wi-Fi 7 is off. Enable 6GHz and WPA3 on the router, then reconnect the Slim 7 Gen 9 to the 6GHz SSID.
