Im frm Subang as well. Problem started yday midnite around 2 when there was a few seconds power trip. Cant connect ever since then.

update:
after many calls to their call center, just gave up on their typical responses. last time a maxis technician gave his number and asked me to call him if there was an issue. so i called him and he asked me to hard reset the thomson (use something sharp to poke the hole between the 2 usb ports).
then wait for it to restart, connect to the wireless (the new SSID and password will be defaulted as per the label at the bottom of the router).
go to the main thomson page and run the configuration wizard. it's quite simple as the values are already stored in the text boxes, just click next all the way through. for the password, it's the username + the digit '1'.
once it's configured, then u may change the ssid and wifi password to one of your choices.
phone wasn't working now (got engaged tone). called the call center and she said the password for the voip phone is your phone number + the digit '1'. after registered the phone, it was working.

hope this helps. but i'm worried theproblem might happen again. this thomson junk has way too many problems.
