I have a modem router Telsey CPVA642, which works flawlessly with openwrt 12.9 by falshing the image [1]. However, any other versions like [2] and [3] do not work. In fact, the router seems to not complete the booting procedure i.e., no ping answer.

My problem is that I need the driver rtl8192c, which is supported only by BB and CC version.

Does anybody have an idea of what is going on?

Thank you very much
