The gigabit connection is limited to 100Mbps
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
After the last firmware update, my decos lan ports limited the speee to 100Mbps (M4 has gigabit ports). However my wireless speed is 300Mbps, the same as the provided by my ISP.
My network topology is:
ISP router (wired) -> M4-main deco (wired)-> 5 port gigabit switch (wired) -> 2 M4 decos
I already tired to connect directly a laptop to the main deco and test the speed. Same result, only 100Mbps. Can somebody help me? It is frustrating.

Hey
How are you running the Deco? Is it in Router or Access Point mode? From what you describe its best you use Access Point mode as this will fully enable the 1gb backhaul

However as you mentioned you connected into the main deco and it still read 100, how are you testing this? are you sure the device you have plugged in is a 1GB network card?

Hi, maybe it is the Ethernet cable issue and have you tried to change a different cable?
By the way, could you please also check the Ethernet link speed on the laptop:

Hi, I would like to forward your case to the senior engineers.
At the same time, could you please help me check the following information:
1. Did you have any IPTV/VLAN settings on the Deco?
2. Please refer to this link to change the satellite Deco as the main Deco to have a look:

Thanks for the reponse. I found the problem. There was an problem with 2 lan cables, they fit perfect with the laptop' and other devices LAN ports, but they don't fit properly with the Decos' LAN ports. So it seems that they had a bad physical connection with the Decos. I replaced them and now the whole network has a speed between 250Mbps and 300Mbps.
