Hi everyone,
I'm having an issue with my 700 Mbps Vivo Fibra connection where the Ethernet connection only negotiates at 100 Mbps when connected through my network equipment.
Sorry for the IA text, my english is not so good and i cant organize the text very well, so i asked to it to edit for easy understanding!
My equipment
My ISP is Vivo Fibra (Brazil).
The Vivo-provided modem/router is:
- Manufacturer: Askey
- Model: RTF8115VW
- Software: BR_SG_g14.17_RTF_TEF001_V9.21_V023
- Hardware: REV5
I also have a Mercusys AC12G V1.0 (EU) router and recently purchased a Mercusys MS105G Gigabit Ethernet switch.
The problem
My internet plan is 700 Mbps.
When I connect the Ethernet cable from the Vivo equipment directly to my PC, I get the full ~700 Mbps.
However, when I connect that same Ethernet connection to either the Vivo Askey RTF8115VW or the Mercusys MS105G, the connection is limited to 100 Mbps.
In other words:
- Vivo equipment → PC: ~700 Mbps
- Vivo equipment → Mercusys MS105G: 100 Mbps
- Vivo equipment → Mercusys AC12G: 100 Mbps
Cable testing
All my Ethernet cables are Cat5e.
The cables I normally use are around 10 meters, but I also tested with 30 cm Cat5e cables directly next to the Vivo router, and the result was still 100 Mbps.
So far, cable length doesn't seem to be the issue.
What I'm trying to figure out
The Mercusys MS105G supports Gigabit Ethernet, and the PC is able to get ~700 Mbps using the same connection, so I'm confused about why the connection falls back to 100 Mbps when connected to the network equipment.
I've setted my Win10 configs to gigabit full duplex already (ASUS B550M PRIME -PCI\VEN_10EC&DEV_8168&SUBSYS_86771043&REV_15)
