I experienced dns lookups that timeout and web sites that fail to resolve until I do a refresh, and I've attributed this (without much substantiation) to something to do with Starhub's DNS servers. It does seem to have improved recently though. Have you checked whether - DNS queries to your router actually resolve? - is the slow resolution caused by querying the router? I've also considered switching to other DNS servers, eg. opendns, google public dns, pacific internet or singnet dns, etc. Conclusion was that switching would make overall browsing slower, as content distribution networks based on anycast dns would serve content via non-optimum network paths (eg, via servers in hong kong or the US instead of servers within starhub's velocity program in singapore). So I'd just about given up and resigned myself to reloading where necessary - but seriously, my perception is that this problem isn't as bad as it was in the past. The other alternative, of course, is to run your own dns resolver. Perhaps on your wireless router.
