Out of the box they were troublesome but firmware updates made them some of the better routers I've had.
As to your issue, it's too rare a setup so you should try other routers.
Hello guys and girls,
so i have a Huawei modem (Version: AV1HA35M VER.A) with an integrated router running 2.4 ghz wifi. In addition I have a powerlan setup from devolo (devolo 500 wifi). Those two are running just fine. The connection is good and the Ping is really nice (mostly under 10 ms from the pc to the modem on wifi).
However, i have an Archer C9 V2 with the latest firmware which I configured as a Bridge. When I ping my modem while being connected to the bridge WiFi from the Archer I get really poor ping.
I assigned the Archer a static IP 10.0.0.139 (modem has 10.0.0.13 and disabled the DHCP server on the Archer. I cannot reserve the IP 10.0.0.139 on the modem as it doesn't show the Archer and his MAC in the network.
I also just recognized that from time to time I cannot reach the Archer Interface on 10.0.0.139.
I cannot explain why this is happening so I was hoping someone of you can help me figure this out.
