have a nice trip then!
I can recall the good old days when some IT engineers I know made it as an alibi that they still cant be able to solve the network problem in the remote site just to extend their stay. Happy vacation for them.
Anyways, if you have a way to get a cheap unlimited call to manila, then remote assistance would do, but you should make sure somebody out there can follow instructions by the letter.
Second option is to get an identical router. Configure it here and send it to Makati.
Depending which is cheaper. A new linksys router or an roundtrip airfare.
