Q3. Browsing is fine but I cannot run certain applications, such as ICQ.
Check that your firewall security setting is not too high. Try temporarily
disabling the firewall. If the application now runs, you can either lower the
security level setting, or tailor your firewall settings to allow traffic of the
application through.
Q4. My customised Router administrative password has been forgotten and
the Router control panel is no longer accessible.
Restore the Router to factory defaults. A hidden reset button is located next
to the power on/off button at the back. Using a suitable size pin, while the
Router is powered on press the reset button for several seconds and release.
All the front panel lights should come on indicating a successful reset.
