I went for an Asus RT-N56U as it was going for £36.50 on Ebuyer and is a dual band router with decent reviews. Hopefully this will be powerful enough to reduce my connectivity issues. To be fair, that TP-Link router is better than a D-Link I had which was supposed to be good and I like the compact design of it. The other bonus with this router is the ability to plug a memory stick in and use it as a UPNP device to stream music to the iPad / other device for playback.
