The 90789 is designed for “Plug-and-Play” deployment, though SKYRS recommends a specific sequence to ensure maximum throughput for networking.
Direct Connection: For best results, connect the 90789 directly to a USB-C/Thunderbolt port on your device rather than through another hub or extension cable.
Cable Choice: Use a Cat6 or higher Ethernet cable to achieve full Gigabit (1000 Mbps) speeds. Older Cat5 cables may cap your speed at 100 Mbps.
Peripheral Loading: Connect high-draw devices (like external hard drives) to the USB ports after the Ethernet connection is established to prevent power-surge re-syncing.
Driver Check: While modern OS versions (Windows 10/11 and macOS) auto-detect the unit, legacy systems may require the AX88179 driver installation for full duplex support.
In Pakistan, SKYRS provides exclusive value-added services and configurations that ensure the 90789 operates at peak efficiency in local network environments.
Network Throughput Verification
SKYRS provides an on-site or remote “Gigabit Handshake” audit. We verify that your specific ISP router and laptop hardware are negotiating at full 1000Mbps, eliminating the “speed bottle-necking” often caused by incorrect OS settings or local interference.
Variant Selection
We maintain the full variant lineup in our Pakistan warehouse:
Space Grey Aluminum: Standard high-durability finish.
Extended Cable Variants: Special order versions for iMac users who need the hub to sit flat on the desk.
Enterprise Bulk Configuration
For corporate offices in Pakistan, SKYRS offers pre-configured MAC Address whitelisting. Our technical team can document the unique MAC address of each 90789 unit before delivery, allowing your IT department to pre-set security permissions for your employees’ remote setups.
Exclusive SKYRS Warranty
Available only at SKYRS, each unit comes with a specialized “Heat-Stress” replacement guarantee, ensuring that if the hub fails due to 24/7 high-speed data transfer in Pakistan’s summer temperatures, it is replaced instantly.
Note: The specialized MAC address documentation and local heat-stress warranty are services provided exclusively by SKYRS for the Pakistan region.
