The primary pain point of the original UDR was the CPU bottleneck, which limited throughput to ~700Mbps when IDS/IPS was enabled. UDR7 features a high-performance processor capable of 2.5Gbps+ with full security features. It also introduces Wi-Fi 7. If you are moving to a 2500Mbps fiber plan, UDR7 is a necessary upgrade.
Detailed Comparison Table:

In Hong Kong, concrete load-bearing walls are the ultimate Wi-Fi killers. While UDR7 supports the new 6GHz band, physics dictates that higher frequencies have poorer penetration. If your flat is over 500sq. ft. or has a complex layout (e.g., diamond-shaped living rooms), a single UDR7 in the living room will not suffice for the bedrooms.
Deployment Scenarios for HK:

• 300-500 sq. ft. (2-Bedroom): Central placement in the living room should provide adequate coverage.

• 600+ sq. ft. / Long Hallways: Utilize the PoE+ ports on the UDR7 to run a LAN cable to the back room and add a U7 Pro Wall. Enable MLO (Multi-Link Operation) for seamless roaming.

It is highly recommended to buy Official HK Stock (Authorized Distributor).

1. Warranty Pain Points: Parallel imports (e.g., US versions) might save you a few hundred dollars, but if a port fails, you must pay for international shipping back to the origin for repair. HK Official Stock (Distributors like Hin Kwong Computer) offers 2 years local 1-to-1 replacement.

2. Power Plug: Official stock comes with the UK 3-pin plug, ensuring stable power delivery for PoE devices without flimsy adapters.
