How to connect a Flex 6400 to a LAN via a wi-fi extender LAN port

jerryh Member
Hello All,

I'm a new Flex user and am trying to initially connect a new 6400 to my LAN. My access to the LAN is via wi-fi. I have near my station a Airi wi-fi extender which has two ethernet ports. I'm assuming I should be able to connect to the LAN by connecting the 6400 RJ-45 port to the LAN port on the extender. However, I'm not finding the 6400 on my Windows 10 pc.

I've looked in the Community data base and haven't found any articles or forum posts on this. Any help would be appreciated! I'm assuming the Flex 6400 should show up on my networked devices that I see on the Control Panel Networking tab. Should I be looking somewhere else? If there is a step-by-step process someone is aware of please let me know!

Many thanks,

Jerry, K7JPF

    Could be a lot of things, but generally WiFi especially through an extender may not be a satisfactory approach. WiFi can have significant latency, especially with the quantity of real time data in the operation of the radio. Maybe for an initial test try connecting the computer directly to the radio with the supplied cable (or equivalent if more length is needed). Don’t even need an antenna connected, just to rule out radio/computers issues with the connection process.

    John, Many thanks for your comments. I have the networking running now using the extender. So far, latency has not been an issue. I will monitor.

    What steps did you take to make it work?

    I’d also like to know how you did it. For example, does,your Wi-Fi extender have LAN ports where you have devices connected (my scenario) or are you running all components on Wi-Fi?

    Duane, IDK your configuration, but from my experience WiFi extenders are a lower choice. TP-Link, among others, has power wiring adapters that work well. These were recommended by Mike.

    i installed one at the router near the service entrance and another in the shack at the other end of the house. Both ends use wired connections. In the shack, the adapter connects to a switch which is connected to the radio and the pc. Works well.

    Ok, I’m up and running again but I’m not positive why. I pulled the switch out of the arrangement and now have PC, Maestro and 6600 plugged directly into the extender’s LAN ports. This was the config that sort of worked except the transmit would drop (FT8) anywhere from 1 to 10 seconds into the exchange. What I see as different now is that the PC is definitely connected via the ent port and not Wi-Fi. That may be the key as someone gave a clue to it above. I will test it more thoroughly over the next few days and if it holds I’ll disable the PC’s Wi-Fi adapter. I’ll report status after more testing. Thanks all for suggestions and ideas.

  • Similar problem. Have a WiFi extender that has a WAN address of When the radio boots, it DAX and CAT show IP of doesnt work of course. However; that is the same IP I get when I connect the Flex direct to the computer. Or, when I get the, when trying to connect remotely, I see the radio, then when I try to connect, it disappears.
