Check WWW for Software Upgrade” fails to download the upgrade
file
The IPWireless system allows the 3G Modem and the PCDialler to have
its application software upgraded with the minimum of user interaction.
The purpose of the upgrade is typically to supply additional functionality
and to provide bug fixes. Subscribers would normally be notified of the
existence of an upgrade by checking the IPWireless web site (see the
release notes for the actual web site address). One change that could be
made to the 3G Modem would be to indicate to the user directly, perhaps
by means of a flashing LED, that a new upgrade was available. This
change would, of course, be provided in a software upgrade!
If the download of the software upgrade aborts before the progress
indicator has even appeared, this may be because a more recent load is not
available on the IPWireless server. Alternatively, it may be that the
IPWireless server is temporarily unavailable. Try checking for the
download in a day or two.
If the download aborts before the progress indicator reaches completion,
then it is likely that the wireless link to the base station has been lost. Try
using the web browser to check if a connection to the IPWireless server
still exists. If it does, then repeat the WWW software upgrade procedure
again. If not, close down the PCDialler application, and restart it, then
reconnect to the IPWireless server and try the download again.
