I have one client connected with MT CPE that issues IP to client device. MT device is dhcp-server. Client device is D-link wifi router.
I client's laptop directly connects to CPE with Ethernet cable, dhcp data is exchanged and everything is fine.
If client's brand new wifi router is connected to Ethernet cable, it only works some time and than looses IP address and gw and dns setting. (wifi router is dhcp-client). After that, even after reset of the wifi router, no dhcp data is exchanged between MT device and wifi router.
If wifi router is set to ´access point´ mode and thus as bridge it is not passing dhcp request fm laptop to MT device, nor does the wifi router get an IP from CPE.
Changed this brand new wifi router for other brand (TP-Link) and new router and the problem is exactly the same! These routers work normally fine in my network, I have about 60 of these running.
Both troubled routers back home at my desk don't have a single problem to request and or pass dhcp data.
We already replaced all Ethernet connectors several times and basically are out of options.
Any suggestions?
While writing this, I see in the MT log that that the dhcp-server is offering the lease, but it is not successful...
