Title: Building a WiFi access point
Post by: eno on January 01, 2015, 12:30:59 AM: Ive ordered and received the Edimax EW-7811Un (See http://www.amazon.com/gp/product/B003MTTJOY/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 (http://www.amazon.com/gp/product/B003MTTJOY/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1)), a USB WiFi dongle. I would like to create a WiFi access point. Im assuming Ill need to figure out which kernel modules will activate this dongle, add config settings, dhcp and some routing. Im wondering what the preferred way to do these things in Tiny Core Linux?

...very cute :)
Wasn't you thinking about disassembling this dongle, cutting off the USB-port, connecting the dongle board to RPi board using small, thin wires and soldering them right on the RPi board?
This may save you even more space and ports...

True dat. But this is my first time building something substantial from a Raspberry Pi and its literally been years since Ive done any soldering. Also, being able to swap out the WiFi dongle when it fails or if I want to upgrade is kinda useful :-)

What wou;d be really cool is to add a 4G USb dongle and being able to provide fallback routing via cellular if no decent Ethernet is available...

hostapd added to 6.x repo

Is iptables available for 6.x yet?

Code: [Select]

Looks like RealTek provide their own version of hostapd for this device...

I was able to build their version of hostapd after installing the linux headers extension. I will test configurations and report back.
Title: Re: Building a WiFi access point
Post by: eno on January 13, 2015, 10:42:47 PM: So good news: it seems to work as advertised. I built hostapd from their sources and used the sample config files with SSID and password changed. The setup involved setting up forwarding with sysctl, Im routing between eth0 and wlan0 using iptables and running udhcpd and hostapd on wlan0.

Dont know if its worth building a special extension for their hostapd ?

Hello Eno,
I'm interested on the hostapd for realtek compilation. Are you going to create a hostapd versioned packaged? or at least could you provide the one that you have compiled?

Thank you

Post by: gpulido on February 11, 2015, 01:45:31 AM: BTW, I have been playing with the hostapd provided by adafruit (check https://learn.adafruit.com/setting-up-a-raspberry-pi-as-a-wifi-access-point/install-software) and
wget http://adafruit-download.s3.amazonaws.com/adafruit_hostapd_14128.zip

It seems to work.
