Hi As you did not describe the problem, it will hard for someone to assist you.
In this Community forum, there are experts who could advice you to resolve your problems.
For your info, wireless is thru Router, it is not Starhub responsibility.
Unless it is due to wired connection, then Starhub will check on their end.
Hence you need to do wired connection to check confirmed.
Wired connect directly from the either; fibre ONT or cable modem; to your computer.
Just remove the router cable on the ONT/cable modem, and plug in using cat5e or cat6 ethernet cable, and the other end plug to the computer.

As what @eric3743 had mentioned,
"Whats the problem with Starhub ???? Absolutely pathetic responses to continual signal drop. Repeated calls and failed follow up. 100 mps at 9am and 1.5 at 7pm onward. Today 0 mps all day. 5 calls over past 2 weeks and not a single solution or satisfactory answer."
what do you expect us forumer to answer or provide assistance to your question?

Further to that, Starhub is an Service Provider and not a God, they can only know whats your issue after some troubleshooting on both their end and your end.
