I get high ping usually at night making it impossible to play online games i called and just talked to the broadband team today but the guy said 'nothing is wrong on our end' and also said that he just checked and found out that the high ping im getting is from the game's server and hung up which doesn't make sense because i not only get high ping in the game but also when i ping websites and check online. Really don't know whats going on and no point calling back because apparently nothing is wrong.
Thank you for trying that though I'm not seeing a new IP address assigned from here, which should happen when modem mode is enabled. I wonder if it worked correctly for you? If not it might be worth another try
Having said that, I have completed some diagnostics from here. Pings from the default gateway are fine, no packet loss and no high ping times. Pinging your modem from the default gateway though showed a different story:
1000 packets transmitted, 957 packets received round-trip min/avg/max = 0/9/150 ms
I can see that you have already been notified about a fault that might result in reduced speeds at peak times, and that could explain higher ping times during those hours. However, my checks show that Internet usage at those times has dropped and is currently reporting as very low.
