Hi Adrian, Thanks for the information. Unfortunately from the information you have given below the Router is only capable of a 802.11b/g - 2.5GHz wireless network. NOT a Dual-Band 802.11b/g/n - 5GHz - 2.5GHz Wireless Network.
If this is the case, the only option you have is to perhaps try changing the Channel from 11- to channel 1 or 6 or 13 which don't overlap, and see if it makes a difference. If the channel numbers are 5 or more apart, they don't overlap each other. If they are less than than 5 apart, they do and you'll get interference. You can download iStumbler <http://istumbler.net> which will show any other wireless Networks (neighbours) within range of your Network and show if they are using Channel 11. If so you need to select a channel away from 11. But, if this problem has only arisen since you updated to OS X 10.7.4 I would think it is not due to channel or 2.5GHz wireless network; but with the Wi-Fi driver IO80211Family.kext (version 4.2) that ships with OS X 10.7.4. Some iMac users have found replacing this .kext file with IO80211Family.kext (version 4.1.2) which came with OS X 10.7.3 stopped the Wi-Fi drops. Test with trying different channels to see if it helps.
