Hello. I'm on VIP5, got upgraded to 10Mbps few months ago.
My area is Seri Kembangan. For the past 2 weeks until today I've been having problems with the Internet, especially at night/midnight. Most of the time I can't even open any website, it'll just keep loading and loading. And whenever I think it's stable, opening ONE website will cause the ping to shoot up to a whopping 1000!
Of course, I've done the basic stuff like restarting router and all. Called up TM twice. On 11/10, operator told me there was a maintenance going on around my area and it's affecting tons of customers. Told me it would be okay the NEXT DAY AFTERNOON.
Same thing for the next 2 days. 13/10, called them up again and this operator told me there was NO maintenance, at least none that's affecting me. She helped me to only switch the port and problem still remained. Told me to wait till next day.

I don't even know what I should ask... Like, is there any real maintenance going on or what should I do?
Using wireless or wired? Try restart both btu and router. And make sure your router and btu aren't overheating. Make sure there's enough ventilation or you could use a fan.
