RPi3 as a Wifi Repeater-Bridge

Mon Mar 27, 2017 9:50 am

Hello,
I try to find solution over internet but "nothing" describe my problem (or I'm searching n00b - sorry :/).

Introduction:
In my location I use 2 routers - Asus N56U [R1] configured as a main router (get WAN - gives LAN via wifi/eth), second router Linksys WRT54G [R2] with DD-WRT configured as Repeater-Bridge (get internet from [R1] via wifi - gives internet via wifi (new SSID) and eth ports - I switch off dhcp on R2 and all clients in my network gets IP from R1). It is possible to get the same things on my RPi3 (gets internet over wifi - gives inetrent over eth0; routing on R1) ?

What I have:
RPi3, eth cables, basic knowelage in linux.

What i want:
RPi3 connfigured in this way:
- RPi3 gets connection from R1 (ie. IP: 192.168.2.3)
- RPi3 has connection to internet (ie. I can open web pages on it, makes update etc.)
- RPi3 gives connection on eth0 and connected devices gets IP from R1 (they are in the same network)

Any solution will be helpfull ;)

Best regards,
lordo4

Welcome.
You can't bridge a wifi card in client mode. Some atheros cards/drivers will accept violating the wifi standard but the one in Pi 3 does not (like most others I've seen.)
Routing is the usual way people do wifi->ethernet, like: https://frillip.com/using-your-raspberr ... h-hostapd/
If you're looking for sheer pain and frustration you can still try something around proxy arp: https://wiki.debian.org/BridgeNetworkCo ... nsProxyArp

Hmmm... why proxy arp is "sheer pain and frustration"? I use it and it works great with RPi3. Installation and configuration was very simple. All my devices "are in the same network" (they get IP from R1). For now I can't find anything better.
