Furthermore, please be advised that Roku Express is only compatible with wireless b/g/n networks on the 2.4 GHz spectrum. Ensure that your router is broadcasting a 2.4GHz Wi-Fi network for the device to connect to.
You can also try configuring your router and use wireless channels 1, 6, or 11 which are the preferred channels in North America. Each time you change the wireless channel, you will likely need to apply/save changes before you are prompted to restart the router.
@Lydiaowen, it's because you're in the UK the North America issue affects you. Roku devices only support channels available in the US. Your equipment, especially if the channel is set to "Auto", may be using an unsupported channel. Find out what frequency band you're using (2.4 vs 5 GHz) and what channel it's set to.

For future reference, you might be confusing people by calling an Express a "stick". Roku has several "Streaming Stick" models that look basically like this:
Roku Streaming Stick+
.. with a male HDMI plug extending from one end that can be plugged directly into an HDMI port on a tv without without the use of an HDMI cord.
