I've been having performance problems with the wifi connection of my<br>
Mele-A2000 and have finally got around to try and track it down.<br>
I thought at first it was a problem with the 8192cu driver in my (stock<br>
Android) firmware (e.g. its reporting large amounts of dropped RX), but<br>
it seems like this is not the problem.<br>
<br>
The symptom:<br>
TCP connections (e.g. rsync-over-ssh) between the Mele and other<br>
GNU/Linux machines on my home 11g-with-wpa2 wifi tend to be *very* slow<br>
(while the speed can go up to around 1MB/s occasionally it often crawls<br>
below 100KB/s), and while such a transfer is on-going interactive SSH<br>
sessions between those same two machines are barely usable, sometimes<br>
waiting tens of seconds after each key to see it echoed back on screen.<br>
Sometimes the communication completely freezes for a minute or so.<br>
<br>
This happens with the stock Android 4.0.4 firmware (running kernel<br>
"3.0.8+"). It also happens with the kernel 3.4.29 from the Fedora-18<br>
boot image. And it also happens with that kernel-3.4.29 using an<br>
external USB dongle (using the rt2800usb driver).<br>
<br>
During those events, the Mele is mostly idle, and neither dmesg nor<br>
syslog shows anything enlightening. And the wifi network is also mostly<br>
"idle" (and communication between other GNU/Linux machines on that<br>
network never display such behavior).<br>
<br>
In all those cases I'm using the userland is a Debian testing<br>
distribution, installed in the /dev/sda1 partition of my HDD (in the<br>
case of the stock Android, it's running in a chroot on top of Android).<br>
<br>
I'd appreciate some help trying to fix this problem (this Mele is meant<br>
as a home server, so wifi connectivity is very important), or at least<br>
some help tracking it down.<br></blockquote><div><br></div><div>You could try this if it helps: <a href="http://linux-sunxi.org/Wifi">http://linux-sunxi.org/Wifi</a></div><div><br></div><div>-Jari</div></div>
