Seminar and Workshop - Introduction to APRS at RSMY on 3rd May 2014.

We would like to thanks all participants who made themselves available for the seminar. They were coming as far as Kelantan and Johor to be in the seminar. As the organiser, we're really grateful for all of them and when we planned for this seminar, we did not expect that we're going to get more than 40 participants, but the seats were booked quite fast and we added another ten seats extra.

TP-Link Archer C7 V2 - OpenWrt (trunk - Barrier Breaker)

Was looking for the best AC wifi router to replace my Buffalo WHR-G300NH and found that TP-Link has just released an Archer C7 V2 which has wifi card supported by ath10k driver based on the information found here.

Here is the packaging, it says that it supports Unifi & Maxis Fiber but the support is not out of the box. You need to ask the seller a beta firmware which has VLAN support but I couldn't get mine working using even the beta firmware on my Maxis Fiber. Emailed TP-Link support but got a reply saying that they don't have Unifi/Maxis Fiber ready firmware and asked if I want to swap with one that already have, but nah, I bought the router not for running the stock firmware anyway.



Ver 2.0 hardware as per the sticker.

Anyway, I waited for a week or so and someone came up with the new hardware profile which creates the correct firmware image for OpenWrt. If you've this new V2.0 hardware and wanted to run OpenWrt on it but couldn't wait to get the patches into the trunk, check this patches:


To build your own OpenWrt firmware for this ver 2.0 hardware, followed these steps:

1. Have Debian 6.0 or any development system which could cross-compile the OpenWrt firmware. There are many guides available on the net, but for me, I've a VMWare Debian 6.0 VM ready on my Hackintosh machine. 
2. Follow the guide found in: http://wiki.openwrt.org/doc/howto/obtain.firmware.generate. Follow the steps to get the trunk, untar the file and apply the above patches.
3. To generate the image, I was using the following command, I need the ath10k and luci support in the image:
$ make image PROFILE=ARCHERC7V2 PACKAGES="ath10k luci"
4. The generated image ready to be flashed can be found in the bin/ar7xxx/ as openwrt-ar71xx-generic-archer-c7-v2-squashfs-factory.bin
5. Go and flash the firmware, do remember, the default IP address for OpenWrt router is 192.168.1.1.



To get Maxis Fiber to run, just go to network->vlan and have the following, surely don't forget to set the PPPOE userid and password:


That should be it.
