Pros & Cons
Pros
- ✓ AX1800 dual-band: up to 1201Mbps on 5GHz, 574Mbps on 2.4GHz
- ✓ USB 3.0 interface, not USB 2.0, so the bus can actually carry 5GHz speeds
- ✓ WPA3 support alongside WPA2/WPA/WEP for old and new routers
- ✓ Driverless on Win11/Win10 - Windows detects and installs it automatically
Cons
- ✗ Windows 11/10 only - no macOS, Linux, or Windows 7 support
- ✗ No Bluetooth, unlike many PCIe WiFi 6 cards in the same price range
- ✗ External antenna adds bulk despite the nano-size body claim
- ✗ Needs a WiFi 6 router to hit 1201Mbps; older routers cap it far lower
Manufacturer description
The Nineplus USB WiFi Adapter brings WiFi 6 (802.11ax) to desktops and laptops that shipped without it, using a USB 3.0 interface instead of an internal PCIe card. The dual-band radio reaches up to 1201Mbps on 5GHz and 574Mbps on 2.4GHz, for a combined AX1800 rating, so 4K streaming and online gaming have headroom that older 802.11n dongles never had. USB 3.0 matters here: the bus itself has to carry more than USB 2.0 can before gigabit-class 5GHz speeds mean anything. A high-gain dual-band antenna handles reception, and the nano-style body keeps the adapter from crowding the USB ports next…
SpecPicks Verdict
SpecPicks scored Nineplus USB WiFi Adapter for PC Desktop using a rating × review-volume × price-fit model applied to published specs and reviews across the retro networking cards category. Nineplus's retro networking cards lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for retro networking cards of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.
Frequently Asked Questions
Does this WiFi adapter work on Mac or Linux?
No. Nineplus lists Windows 11 and Windows 10 only. macOS, Linux, and Windows 7 are not supported, so check your OS before ordering.
Do I need to install drivers?
No. On Windows 11 and Windows 10 the adapter is plug and play - Windows detects it and installs the driver automatically.
What speeds will I actually get?
The adapter is rated up to 1201Mbps on 5GHz and 574Mbps on 2.4GHz (AX1800 combined). Real speeds depend on your router, distance, and plan.
Can I use this in a USB 2.0 port?
It will connect, but USB 2.0 does not have the bandwidth for the 1201Mbps 5GHz link. Use a USB 3.0 port to get the rated throughput.
Does it support WPA3 security?
Yes. The adapter supports WPA3, plus WPA2, WPA, and WEP, so it can join current WPA3 networks and older ones.
