Just call the ISP you subscribe
Singtel, StarHub or Pacific
If it is Pacific internet, you can call their Technical Helpline
directly : 6336-6622 (24 hrs)
They should be able to help you; small problem
using internet explorer? go to tools, internet options. click on the connections tab and then go thru your list of connections. select whichever connection u r using n click on settings.
if u r using broadband, proxy server option should be unchecked.
if u r using dialup, check tat your proxy server is correct.
sometimes it just happens that there's a network problem with your ISP. like unable to connect to foreign DNS servers... you're accessing clubsnap so that means your internet is still working.. try again tomorrow ?
