Frequently Asked Questions
Will the FENVI AX5400 fit in my PCIe x1 slot?
Yes. The card works in PCIe x1, x4, x8 and x16 slots, so a spare x1 slot is enough.
Do I need a WiFi 6E router to get the full speed?
To use the 6GHz band, which is rated at up to 2400Mbps, you need a compatible WiFi 6E router. On an older router the card still connects over 5GHz (up to 2400Mbps) and 2.4GHz (up to 574Mbps).
Does it work in a small form factor or slim desktop?
A low-profile bracket is included, so the card fits most slim cases. It is listed as compatible with major desktop brands such as Dell, HP, Lenovo, ASUS, Alienware, Acer and Gigabyte.
Which operating systems does this WiFi 6E card support?
The listing names Windows 10 and Windows 11 64-bit. You download the drivers from the FENVI website. Check with the manufacturer before relying on any other operating system.
Why is the card not working after I installed the drivers?
FENVI recommends disabling any old WiFi and Bluetooth drivers in Device Manager before you install. Conflicting adapters are a common cause of setup problems. Check the FENVI website for the latest driver package.
