Recently I’ve come around an old access point that I completely forgot about.
It’s a Wi-Next Naawigo Mini N that, years ago, I put in a closet bacause it had a locked firmware that made it useless.

When I saw it again I tought it could be of some use if only I could manage to flash OpenWrt on it.
Well, I took it apart and discovered something very interesting:

A quick visit to Google Search and Google Images revealed that this board is a common Compex WPE72, already supported by OpenWrt!
I also learnt that its stock firmware is based on a customized OpenWrt distribution by Wi-Next.

McOnsen Netpad O’2 (orgogliosamente spacciato per italiano, ma rebranding di un prodotto cinese) è un tablet Android dalle limitate capacità.

Sorvolando sul pessimo supporto fornito dal produttore (non hanno mai risposto ad una mia mail di richiesta di assistenza) sul loro sito mancano specifiche tecniche, manuali e download di software o firmware.

Per fortuna, la comunità di hacking attiva su questa famiglia di prodotti basati sul SoC WM8650 ha prodotto una buona ROM con pieno supporto all’Android Market.

Prima di cominciare,
vi ricordo che quelle che seguono sono operazioni rischiose, che potrebbero danneggiare il vostro dispositivo.
Nel mio caso è filato tutto liscio… ma non mi assumo alcuna responsabilità per eventuali danni a terzi!

Riporto qui una vecchia guida, che scrissi nel giugno 2008, il cui scopo è quello di riconfigurare il Maxtor Shared Storage 2 per abilitare lo streaming dei file DivX verso la PS3.

Oggi scrivo per tutti gli sfortunati possessori di questo fantastico router ADSL, ebbene sì! Vi illustrerò come salvare gli € spesi per questo baracchino, cambiando il firmware (quello originale è pessimo e buggato) e risolvendo il problema del surriscaldamento che causa i frequenti blocchi riscontrati soprattutto in condizioni di alto carico di rete.

Ecco come si presenta la cavia, prima di diventare il frankenstein informatico di turno...

La procedura non richiede di aprire il router, ed è relativamente facile. Per installare OpenWrt bisognerà modificare le partizioni della flash, tramite il server FTP modificato del bootloader ADAM2. In caso voleste ripristinare il vecchio firmware, dovrete ripartizionare la flash coi valori originari (che io non mi sono segnato! ma sono facilmente individuabili nel programma CICLaMaB) per poi ricaricare l’immagine del firmware D-Link. Detto questo passiamo ai fatti! Read the rest of this entry »

Awesome post title… anyway,

This is how I built a powerful Wi-Fi ADSL router, using my ALIX2D3 (previously running PFsense), a spare USB ADSL modem (Trust MD-3100) and a CM9 atheros-based miniPCI card.

I’ve got some spare ADM5120 boards with 1 ethernet port and 1 miniPCI slot.

I tried to build an Ethernet/Wi-Fi bridge box, but I were a little disappointed when i found out that the bridge package didn’t work with my Atheros AR5414 based miniPCI Wi-Fi card set in sta (managed) mode. Why? I don’t know!
Both eth0 and wlan0 enters promiscuous mode, but packets aren’t forwarded.

In old Whiterussian release, you just had to put your Wi-Fi interface in wet mode, bridge it with your ethernet interface(s) and everything worked out-of-the-box.
Unluky me… Kamikaze seems to have lost this wonderful option!

So, after an afternoon spent googling, I found parprouted: just what I needed.  The man page states: “parprouted is a daemon for transparent IP (Layer 3) proxy ARP bridging“. Seems complicated, uh?! Anyway, it just fakes ARP replies on both interfaces acting as a proxy for the hosts’ ARP request on both sides of the bridged lan. Just like a hacker’s man in the middle attack.

To install parprouted, you may have to rebuild and reflash your OpenWrt image if your router hasn’t opkg. That’s my case, since my board only has 2MB of flash and I removed it to free up space.
Anyway, I’ll explain both ways (rebuild or opkg), since it’s very simple.

UPDATE 20 June 2009

I’m working with Gabor, the ADM5120 target mantainer of OpenWrt. He’s interested in officially supporting this boards. Our purpose is to dump the original bootloader to build OpenWrt images that doesn’t need bootloader replacement. Stay tuned!
OpenWrt forum discussion is located here: http://forum.openwrt.org/viewtopic.php?id=19682

UPDATE 25 June 2009 12:50

Gabor officially relased the port this morning!
Details here:
https://dev.openwrt.org/changeset/16558
And forum thread here:
http://forum.openwrt.org/viewtopic.php?id=20811
Original bootloader dump should arrive soon!

UPDATE 25 June 2009 13:00

Original bootloader download:

HowTo install OpenWrt Kamikaze 8.09 on OSBRiDGE 5GXi/5XLi wireless CPEs… I’ve been working on this port for months so, please, leave a comment if you find this page useful!
At the moment, works only in NAT mode, no eth0/wlan0 bridging. For this feature, we’ll have to wait for future releases.
If you get poor data rates over your wireless it’s ath5k driver fault, it’s not stable yet, and lot of features arn’t yet implemented. What? Madwifi you say? Oh well, it just don’t fit in our flash while ath5k does! 🙁
And forget dropbear and web interface, there’s no room for them. We’ll use telnet for remote management. (unsecure… I know)
