No, it doesn't, but I was unsuccessfully trying to connect to an adhoc network the other day myself - using my phone to create the network. An xp computer in the house and other phones were having no issue connecting to it though. I didn't really care to troubleshoot it, so I just switched to using bluetooth for the connection. Possibly related. I'll try it again tonight just for grins.. -Greg > 2010/1/19 Greg Oliver <oliver.greg@xxxxxxxxx>: >> On Tue, Jan 19, 2010 at 11:23 AM, Giuseppe Fontana <gfontana13@xxxxxxxxx> wrote: >>> Hi! >>> ping from .1 -> .99 >>>> No ping >>> ping from .1 to <ip of nokia> >> I don't know how to determine Nokia >>> IP.
