I recently had my internet upgraded from the 100/40 package to the 250/40 (L to XL) and I’ve noticed that the speeds I get aren’t quite 250mbps or 40mbps. I am using a Draytek Vigor 165 VDSL modem which is able to use annex 35b supervectoring. This is connected to an Asus GT-AX11000 router.
My modem has four different firmwares, each with different modem codes (reference) but before I go down the rabbit hole of flashing the firmware multiple times to try each modem code, I wanted to see if there’s any point. I am currently using the STD one with the default modem code.
Speedtest.net shows ~187mb down and ~33mb up connecting to the syseleven server. Netflix’s fast.com test shows 190mb down and 28mb up. This is a fair amount short of the 250/40 advertised. While this is much better than the 100mb speeds (nearly double), it’s still 60mbps short. I’m missing out on 25% of the advertised speeds.
These speed tests were done on a computer connected to the router over gigabit ethernet.
The modem’s firmware says that has an attainable rate of 308mb down and 47mb up, but I’m not a DSL expert, so I’m not sure if that’s the max for this modem or the specific line or connection as it’s currently operating.
Below is the information copied from my modem directly.
