wireless router – any recommendation?

Summer season is getting close and I would like to sit (and work) in the garden sometimes. Therefor I guess it would be a good idea to upgrade my wireless router sometime.

At the moment I have a Netgear WGR614GR Wireless Kabel/DSL Router, 54 Mbit/s but it’s range may be wider to my opinion.

From most sites it is hard to compare routers on their range so if you have a recommendation please drop it here.
