I have the 50 Mbps-600GB plan. For the past couple of days, the internet has been fluctuating a lot, with speed down to around 1 Mbps at times, then back up, and ping around 90, and high jitter as well. Since morning, the speedtest have shown improved speed (~40 Mbps), but the internet is still very slow and download speed is less than 50 KBps. I can't understand why is that even the the tests are showing good speed results. Any help would be appreciated. Thank you!!
