Ethernet-Wifi Repeater

Hardware Questions and Recommendations

I got a non-openwrt, preferably inaccessible, upstream linksys e8450 that provides me with an ethernet cable which i want to extend by connecting it to a openwrt netgear ac1200.

How would i achieve it?
I came across relayd and kmod-trelay.

Is kmod trelay used to connect a router to the ethernet of another router?
Could i get more info on such a problem?

Thanks

what do you mena it's inaccessible ? not in your possession ?

why not simply make the AC1200 a wireless client to the E8450 ?

3

Inacessable means i am not admin to configure protocols etcetc. Could you share me info of connecting to the E8450 as a wifi client , using the AC1200 , and acess internet via the AC1200? Again i cannot control the protocols on the E8450.

Network > wifi > scan > join

Put the connection in the WAN zone.

Make sure your LAN subnet isn't the same as the subnet of the E8450.

I'm slightly confused about the topology that you're looking to create -- let's make sure that we're on the same page.

  • Are you trying to simply make an ethernet to wifi bridge (i.e. plug ethernet into the AC1200 device, create a wifi SSID)?
  • Are you trying to connect an ethernet only device (like a computer) to the a wifi network, thus requiring a wireless > wired downlink?
  • Are you trying to extend a network wifi <-> wifi?
  • Or something else?

Hello,
I am trying to plug the ethernet from the E8450 to the AC1200 and then use wifi. I cannot control the E8450.

Could you help out?

how about you answer the questions asked ?

Please confirm -- it sounds like you have an upstream connection (to the internet) coming to you from the E8450 via an ethernet connection. Your intent, then, seems to be to simply setup a wifi network from that connection, right? And is it correct to say that the wifi network will be the same as the upstream network (no routing)?

If that's the case, you want to create a dumb AP configuration:

Connected by cable gives you the choice of bridged (dumb AP) or routed. With the dumb AP, your router is strictly a wireless to wired converter and the upstream E8450 controls all address assignment, routing, and firewall. If you configure your device to route between the two networks, then you can firewall other users of the 8450 out of your devices.

Hello,

This is exactly what i want to do.Setup wifi network with that ethernet conenction.

Could you clarify on the address assignments of the wifi network? I assume only 1 client can be connected to the wifi as it sends the data via ethernet?

What do you mean the wifi network will be the same as upstream? It wont because it uses the ethernet of the upstream while clients connect to the AC1200?

The dumb AP guide lays that all out.... if in doubt, set the device to DHCP client mode for the ethernet connection, and it will obtain an address automatically.

No. Multiple devices can use the wifi simultaneously without issue.

The 8450 has a lan with a bunch of devices on it. Do you want those devices to exist on the same network as your devices such that they can all talk to each other? Or do you want your network to be firewalled (i.e. the other devices connected directly to the 8450 will be unable to reach your devices)?
