Ethernet local network communication issues.
Model :
Hardware Version : Not Clear
Firmware Version :
ISP :
My local network uses a "TP-Link ADSL2+ Gigabit Double Bande AC1750". It has three computers: two connected by ethernet (let's call them 200 and 202) and one by WiFi (called 201).
I'm experiencing network issues when 200 and 202 want to talk to each other.
There are no problems when communicating with 201, the modem router or the Internet, it's just between PCs of the local network connected by ethernet.
Using the ping command from 200 to 202 revealed that packets whose total size exceeds 1487 do not get replies. This goes both ways.
The maximum total packet size when pinging from either 200 or 202 to 201 is 1500, as expected. Here again, this works both ways.
Connecting 201 to the network using ethernet instead of WiFi make the problem occur between all 3.
My modem-router is in Wireless Router Mode, using the EWAN port to get its Internet (again, Internet works fine, it's the communication between computers of the local network that doesn't).
