Slow wifi

[Walli]

Unsure if it is our old modem (Motorola Surfboard cable Modem SB5100) or our airport express router but since upgrading to iPads, Apple TV, smart phone etc our speed has dropped and we are unsure what we need to replace. Any suggestions about how to get a new cable modem and which would be the best router to fix our slow speed. We don't think the speed into the house has dropped.
Thanks very much

I would enqiure about the netgear 3.0 high speed cable model.
