Hi there, I'm writing this to you from an Ubuntu 7.10 system running kernel 2.6.22-14-generic via a Netcomm NB9W. I've not experienced any network connectivity problems other than getting the modem to connect to the outside (which usually has more to do with the ISP than me).
I can't comment on the SPI stuff. I can say that the NB9W uses linux inside, and appears from the logs to be Linux version 2.6.8.1 ([EMAIL PROTECTED]) (gcc version 3.4.2) #1 Tue Mar 20 19:14:41 CST 2007 I did have a lot of problems with the telephony section of the device, with dropping audio, and then with a lack of echo cancellation. These issues seem to have been resolved with the last firmware I installed, which is NB9W_C201-S300NCM-C09_R10.bin . I have been running this firmware for nine months now and I only have to re-boot the device every month or two. I have the wireless part turned off. I hope this helps you to make a decision regarding this modem. Ben. On Fri, 2008-02-01 at 14:38 +1100, elliott-brennan wrote: > Hi all, > > I'm with TPG and thinking of using their VOIP > service.
