@lsdlsd88 Check this comparison - it would be easier to compare. C88 has 4 antennas while C86 has 6 antennas. Other than that the case is different and their physical dimensions.

@Sofia-D No, AX20 doesn't support RE mode or WDS feature - you can use its AP mode only but involves cabling.

@akb_here Do you have access to C80 web management interface ? If you login C80 WebGUI you can definitely check what's the C80 WAN and LAN IP addresses: If you don't know the answer to my question...

@Gokul_Nair That's a serious issue, don't plug the RE into the power socket anymore. Good luck with the warranty claim - it should be honored.

@akb_here From your diagram there must be something going on in Server0 (probably with couple of network cards) which causes this issue. What device and interface (WAN/LAN) is set with IP address...

@Gokul_Nair You can contact your local tech support here. You can probably contact Amazon.in by an e-mail as well. Can you post a picture of the burnt hole ?
