OpenWrt in a WiFi card reader (2017)

Reminds me of these SD cards running Linux<p><a href="https:&#x2F;&#x2F;hackaday.com&#x2F;2016&#x2F;06&#x2F;30&#x2F;transcend-wifi-sd-card-is-a-tiny-linux-server&#x2F;" rel="nofollow">https:&#x2F;&#x2F;hackaday.com&#x2F;2016&#x2F;06&#x2F;30&#x2F;transcend-wifi-sd-card-is-a-...</a><p>Edit also, there was picture frames at one point with bluetooth that ran linux that were hacked, I made a video years ago, funny to look back on<p><a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=FEP0i1zteVM" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=FEP0i1zteVM</a>

In reference to the other discussion recently about whether there were still new big-endian machines being made...<p><a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=16187939" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=16187939</a><p>....the SoC in this contains a Big-Endian MIPS core.

If you want a small, USB-powered wifi device running OpenWRT, and you don&#x27;t need the card reader, you might have a better time with a NEXX WT3020F[0].<p>[0] <a href="http:&#x2F;&#x2F;www.dx.com&#x2F;p&#x2F;NEXX-WT3020F-Portable-Mini-300Mbps-Wireless-WiFi-Router-80211-bgn-Repeater-Bridge-with-USB-Flash-Drive-White-916493691" rel="nofollow">http:&#x2F;&#x2F;www.dx.com&#x2F;p&#x2F;NEXX-WT3020F-Portable-Mini-300Mbps-Wirel...</a>

I use one of these running LEDE.<p>For the original porting work done on OpenWRT, check this link: <a href="https:&#x2F;&#x2F;wiki.hackerspace.pl&#x2F;projects:zsun-wifi-card-reader" rel="nofollow">https:&#x2F;&#x2F;wiki.hackerspace.pl&#x2F;projects:zsun-wifi-card-reader</a><p>For more recent work done to get up-to-date LEDE builds running on the device, check <a href="https:&#x2F;&#x2F;forum.lede-project.org&#x2F;t&#x2F;supporting-zsun-wifi-card-reader-16mb-flash-64mb-ram-ar9331&#x2F;2142" rel="nofollow">https:&#x2F;&#x2F;forum.lede-project.org&#x2F;t&#x2F;supporting-zsun-wifi-card-r...</a>

Awesome! And this device is even cheaper in China (59 RMB, or about 10 USD, including domestic shipping): <a href="http:&#x2F;&#x2F;www.dwntme.com&#x2F;h.Z0L1EYw" rel="nofollow">http:&#x2F;&#x2F;www.dwntme.com&#x2F;h.Z0L1EYw</a>

&gt; the hardware supports multiple simultaneous wireless interfaces!<p>This seems to be a somewhat rare feature... I might get one just to try this.<p>Does anyone know of other cards that support something like this? Is there a difference between being able to associate with multiple APs and being able to <i>host</i> multiple APs (or some combination of both)?

I&#x27;ve been trying to do this for a while, OpenWRT runs but the performance is sub-optimal, maybe it&#x27;s just me or my impatience (or I got a flaky device) but it freezes a lot.

Then there is the vocore2; cheaper and not a repurposed consumer device.

AliExpress link if someone wants it delivered in the US: <a href="https:&#x2F;&#x2F;www.aliexpress.com&#x2F;item&#x2F;Smart-Expansion-ZSUN-Wifi-Card-Reader-Wireless-Adapter-Support-2TB-TF-SD-Card-Wireless-Storage-For&#x2F;32833243622.html" rel="nofollow">https:&#x2F;&#x2F;www.aliexpress.com&#x2F;item&#x2F;Smart-Expansion-ZSUN-Wifi-Ca...</a>

It seems like a very good alternative hardware for the same purposes as USB Armory, for a fraction of the price.<p>I wonder how soon a nice security-oriented package set will emerge. I suppose the USB interface should work as a USB-connected NIC, offering https &#x2F; ssh &#x2F; u2f access to the host on the card.

The main issue would be the antenna. Wifi&#x27;s wavelength is 12cm.

You could set up a little mesh network using them. Very cool.
