There have been several recent reports whereby users of the D-Link DSL-G624T are not able to perform valid tracert and each hop is timing out. There could be several reasons for this.

~ Ensure its not a software firewall blocking access.

~ Ensure that its not an MTU problem and that ICMP isn't turned off in the router.
