Hey, thanks for the great tutorial! It works perfectly with Wifi to Wifi on my Rpi 3 too!

I need your help though, when I connected an ethernet cable to the Pi in order to use it as a regular TV box, it doesn't seem to have a connection after this setup. How should I set up the eth0 to be isolated from the Bridge/AP pair and just act like a normal internet connection where I can stream/ssh into the pi etc?
Thank you!

Thanks Tejas worked out of the box on a Raspberry Pi Zero W. Zero has the builtin wifi and using a USB wifi adapter bought from ThePIHut. So it works fine as such but the speed drops to less than a fifth of what the router that it's connected to can do. Is this due to performance of Raspberi PI Zero W or something else?

I got it running on an old rpi2 using dietPi on a 2gb sd card. using 2 usb-wlan interfaces. just made some slight modifications to get it pointing at the right interface.

Found this guide simpler that what I used previously including hostapd and stuff.

The signal improvement was great but the speed dropped quite a bit, but considering quite old hardware both the rpi and the interfaces it's still a success i think.

I attempted this project on a RPi Model 3B+ and did not get the wlan0 access point to function. It appears that a DHCP server is required but not installed in the project. Any suggestions?

This works great on my Raspberry Pi 3. Thanks so much! I've tried it per your instructions, and also reversed it with my external wifi dongle acting as the AP. Both ways worked fine. I may try with 2 external dongles as the built-in wifi on my Pi3 isn't that great.
Is there a way to have it use WPA2 rather than WPA security?

you might need to have a look at their man page. They have couple of examples listed.

Well, it didn't. I don't have exactly the same hardware, and to be fair, I don't really understand networking details. But this is good inspiration and a starting point to turn my old wireless router into a wifi extender. Thanks.

That is nice :)

Thanks for the inspiration. I have a spare Z and now need a wifi extender. Giving it a shot.

By the way, you probably want to change your country=IN to be your country code unless you happen to live in india.

We'll see if this works...

Yes. You would have to change it according to your location.
