The answer to your question depends on a couple of things:

1. Does your netgear router support SNMP? If it doesn't, I don't believe your request will be possible to do.
2. You want a trigger that goes off for a percentage of what? Percentage of 100Mbps? 1Gbps? You'll have to define that to create your trigger.

The way I would create this is to have items for both inbound and outbound traffic. Then I would set up a trigger something like this:

100*(({g2t0347g.austin.hp.com:net.if.in[{#IFNAME},bytes].last(0)}+{g2t0347g.austin.hp.com:net.if.out[{#IFNAME},bytes].last(0)})/[your_max_bandwith_in_bytes])>[your_threshold_percentage]
