Deco M4 Ethernet connection to PC has lower speed than direct connection from router
Dear TP-link,
I have the following situation:
- Multi-unit Deco M4 deployment, all Decos have Ethernet backhaul towards modem/router
- Access Point mode
- my line is fiber up to 1 Gbps UP/DOWN
- all connecting cables are Cat6.
Here the issue:
- If I connect the PC to the other Ethernet port of each Deco (one port is used for backhauling) I get a maximum speed of about 550 Mbps DOWN and UP (wired)
- if I connect the PC to the wire that is backhauling Deco, I get a maximum speed of about 900 Mbps DOWN (350 Mbps more!).
- I also tried to swap ports, without any enhancement (i.e. same issue/result). I also tried to reboot network, again without any improvement.
It seems that each Deco unit is downcapping the maximum speed at about 550 Mbps, but I don't understand why.
-> Why do I get such behavior? Which setting or setup could be affecting the speed?
-> Could you help me in improving wired speed of devices connected to my Decos?
Thanks in advance
Thanks for your messages. I checked the post and the references provided, and actually to me it seems everything should be fine and should work... but unfortunately I still have the issue:
- Let's consider one of my Decos (the system in working in AP mode), the same applies to all
- In each room where I put Decos there is an ethernet plug directly connected to the modem/router
- I used wired PC and Speedtest for making tests.
Then:
a) When I connect PC directly to the plug, I get more the 900+ Mbps in down and about 600+ Mbps in up (see screenshot below).
In this case I have the following network topology (for each Deco):
Router -> cable Cat6 (3 cables and 2 wall plugs actually) -> PC
b) When I connect PC to any of the two Ethernet ports of Deco, I get about 550+ Mbps in down and about 500+ Mbps in up (see screenshot below).
In this case I have the following network topology (for each Deco):
Router -> cable Cat6 (3 cables and 2 wall plugs actually) -> Deco -> cable Cat6 -> PC
No other changes are done. Two tests are executed close in time, just the time needed to change connections...
-> Why do I get such strange behaviour? It seems that Deco is "down-capping" ethernet speed... Is there any setting or setup to improve the situation?
Hi, thank you very much for the feedback.
Have you also tested the wireless speed directly from the Deco?
Could you please also send me some screenshots of the network map on the Deco APP, such as:
I don't have other suggestions yet and would like to follow up on your case via email.
Please check whether you can receive my email later.
Wait for your reply.
Best regards.
