Questions and answers
Product and performance
Does every USB-C computer reach 10GbE-class throughput?
No. A 10GbE-class target requires a suitable host USB mode and a complete network, cable, driver, CPU, and storage path.
Which host USB mode should I use?
USB 3.2 Gen 2x2 20Gbps is recommended for 10GbE-class targets. A 10Gbps USB host can still provide useful multi-gig networking with a lower ceiling.
Does Thunderbolt or USB4 guarantee full speed?
No. Confirm the USB peripheral mode exposed to the adapter. Port branding alone does not establish the active USB link mode.
Which Ethernet speeds are supported?
The adapter supports 10G, 5G, 2.5G, 1G, and 100M RJ45 auto-negotiation. The connected network equipment and cable determine the negotiated link.
What Ethernet cable should I use?
Use Cat6A or better when planning a 10GbE link. Cable length, condition, and the connected ports still affect negotiation and stability.
Do I need a driver?
Driver needs depend on the OS and environment. Use official or verified sources, then confirm detection, driver version, USB mode, and Ethernet speed.
Is it normal for the aluminum enclosure to feel warm?
Some warmth is expected during sustained multi-gig traffic. Keep the enclosure uncovered and provide airflow. Contact support for instability, damage, odor, or abnormal heat.
Orders and support
How long does shipping take?
Orders normally process in 1–3 business days. US standard shipping is free; other supported destinations are USD $5. Most deliveries are estimated at 6–12 business days after dispatch. Remote areas are not served.
Will I pay import duties or taxes?
Unless checkout states that charges were collected, destination duties, VAT, taxes, or brokerage fees are the recipient's responsibility.
Can I return it if it does not fit my setup?
Eligible returns may be requested within 14 days after delivery. Contact SumoLink first and keep the adapter, cable, packaging, and order details together.
What warranty does SumoLink provide?
SumoLink provides a 12-month limited warranty for eligible manufacturing defects. Throughput limitations caused by an incompatible host or network path are not hardware defects.
What is the relationship between SumoLink and WisdPi?
WisdPi manufactures the WP-UT9 hardware. SumoLink distributes this product and provides storefront sales and customer support for orders placed here.
