Problem with Deco X55 Speed
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Hi, i have some trouble to get more than 100Mbps of data rate when connected by cable to my main Deco. When I do the test connected to the Internet Modem I get 400Mbps. Between the modem and the main deco there is a CAT 6 cable and I've certified that it works in gigabit.
LAPTOP ----- CAT6 cable ------- DECO ------ CAT6 cable ------- MODEM
Internet speed (100Mbps)
LAPTOP ------ CAT6 cable ------- MODEM
Internet speed (400Mbps)
Can anybody help me?
There are two common possibilities: Ethernet cable and Deco app configuration settings.
We can start with Ethernet cables, because if you have close to 100Mbps it often means gigabit link can't be negotiated over the cable. The occasional bad luck is to have Deco app configuration causing exact same drop of speed, but we can leave bad luck for later.
You have two Ethernet cables, and no simple means from Deco to figure what speed is negotiated over them. Still, there are ways.
Have this setup: LAPTOP ----- CAT6 cable ------- DECO ------ CAT6 cable ------- MODEM
Confirm the speed is still 100Mbps, using two different speed test apps: Ookla Speed Test app you can download and install on laptop, and web site FAST.com
If speed is 100Mbps with both speed test apps, do the following to narrow where the issue could be:
1. For cable between Deco and modem.
When you open Deco app, do you see "Abnormal WAN port speed" error message in it:
2. For cable between laptop and Deco.
Check what wired speed is negotiated at laptop's LAN network adapter, see How to check the associated/link speed on a wired client
