to John Elson, thank you for your reply glxgears works fine (once I found it);-)
the latency test runs below 15000ns with glxgears and internet working the worst it has been is just under 20000ns the usb wlan adapter was chosen because it would work with linux, the driver is ZD1211b which appears to be in the lib/firmware/2.6.24-rtai folder, which is why I thought it had been disabled. It has worked with Ubuntu since Hardy Heron was released and with later versions. I'll try editing the ini file later when my head stops spinning ;-) cheers JD On 5 July 2010 18:20, Jon Elson <[email protected]> wrote: > John Dunn wrote: > > With this computer I normally use a Usb WLAN adapter to get online but I > > believe this has been disabled in EMC2. > > > If the correct driver for this device is available, then it should > work.
