thanks for the input cakewey, DTIM on my router was set to 100....with a beacon interval of 100ms.. which meant my wifi devices were ocassionally sleeping for 10 secs! am not sure if these are the default values though.. and can't be bothered to do a factory reset to see if thats the case

Have read that setting it to 1 will definitely solve the problem, though it'll be taxing on the connecting devices as their wifi modules will pretty much be powered all the time. Should be able to tweak around that value to get to a middle ground between connectivity and battery life.
