Arnova 10 supports b/g wireless network. Try to setup your router not to establish n wireless network.

No, WiFi only.

To hard reset a tablet, hold the power button down until it shuts off then press it to turn back on. Should take about 5 - 10 seconds for the device to power off.

Go to the Android Market and search Kindle and install

back up arnova and reflash the firmware. that solved it for me. still the wireless is fickle. sometimes, I tell it to forget network and then refind it. and sometimes it doesn't and I have to manually add it. My hunch is this model may have wireless issues.
