Black Hole

That's what I refer to as a nano-router, and I have acquired some cheap Edimax units to experiment with. But (as mentioned above), they require (a) powering, and (b) configuring separately. If it loses its settings (as it almost certainly will at some point), a non-tech user will be stuffed without technical support, whereas they could be instructed how to reconnect a dongle through the SUI.If dongles don't work, a WiFi gadget that plugs into USB and connects to the Ethernet socket of the HDR is about £10 in the usual tat bazaar and bypasses any driver issues.
