singnet is crap with their troubleshooting.
different CSO gives different troubleshooting methods and
explainations, which totally defers.
i was once told the channel settings thing and when i got d/c again
some time later, i'm told another story for the channel
settings.
obviously singnet and singtel wouldnt admit if they have a problem,
which you wouldnt know if they do. they die die ask you to
toubleshoot and insist nothing wrong is with them.
they will push blame to your 1) router, 2) wireless adapter, 3) pc
settings/compatibility, 4) because it is wireless but never their
fault.
