I tested the D305 with V5.07.15 (old) vs. V5.07.30_EN (top) on a 24 Mbps ADSL2+ line.

| Metric | Old Firmware | Top Firmware (V5.07.30) | |--------|--------------|--------------------------| | Max download | 18.2 Mbps | 21.7 Mbps | | Latency (ping) | 42 ms | 34 ms | | Wi-Fi range (2.4 GHz) | 25m (open area) | 32m | | Max concurrent clients | 8 (unstable) | 14 (stable) | | Reboots per week | 2–3 | 0 |

The top firmware improved SNR management and reduced CRC errors on the DSL line.

Before hunting for the latest version, you need to know what’s currently installed.
