To know if your network is performing well, you need to match your results against theoretical hardware limits. Hardware Setup Theoretical Max Speed Expected Real-World LAN Speed Test Results 12.5 MB/sec ~10 to 11.5 MB/sec Gigabit Ethernet (1 Gbps) 125 MB/sec ~105 to 118 MB/sec 2.5 Gigabit Ethernet (2.5 Gbps) 312.5 MB/sec ~250 to 290 MB/sec Wi-Fi 5 (802.11ac) - Close Range ~30 to 80 MB/sec Wi-Fi 6 (802.11ax) - Close Range ~70 to 150 MB/sec
Understanding your metrics helps you identify if your hardware is performing up to its theoretical limits. Connection Type Theoretical Max Speed Expected Real-World LAN Speed 100 Mbps (12.5 MBps) 90 – 95 Mbps Gigabit Ethernet (1G) 1000 Mbps (125 MBps) 850 – 950 Mbps (105–118 MBps) Wi-Fi 5 (802.11ac) Varies (e.g., 866 Mbps) 200 – 400 Mbps (depending on distance) Wi-Fi 6 (802.11ax) Varies (e.g., 1200 Mbps) 500 – 800 Mbps (close range)
The v3.5.x series introduced several advanced capabilities that remain essential for network administrators: LAN Speed Test - Totusoft
While newer versions like v4.4 are easy to find on official sites, version 3.5.0.0 (your "v350ph") is an older release. As such, it's not hosted on the developer's main site anymore. lan speed test v350ph link
If you are a home user trying to figure out why copying files to your NAS is slow, or an IT pro needing to certify that a new run of Ethernet cabling is performing correctly,
Unlike generic benchmarks that rely on standard browser-based tests, LAN Speed Test measures true local network performance. It achieves this by writing and reading a dummy file of variable size directly across the network. Key Architecture Features
Currently, direct download repositories index a file named . This version is compatible with Windows 7, Windows 8, Windows 10, and even older systems like Windows 98. The file size is notable for being extremely lightweight, often listed as around 439 KB (for the installer package) or as low as 122 KB for the standalone portable executable. To know if your network is performing well,
Outdated Realtek or Intel network interface card (NIC) drivers can cause severe packet loss and throughput degradation.
This comprehensive guide covers how the tool works, how to configure it for accurate results, and how to interpret your local network speeds. What is LAN Speed Test v3.5.0?
Since the PH variant is niche, here is the verified hierarchy to locate the correct binary: As such, it's not hosted on the developer's
Versions like 3.5.0.0 were the stepping stones to the modern version 4.0 and 4.4 releases. Many legacy hardware users prefer the v3 series because it is slightly smaller and runs perfectly on older Windows Embedded systems or Windows XP environments where modern version 4 might have compatibility hiccups.
No installation is required. You can run the executable directly from a USB flash drive or a shared network folder.
