Recently, about a week ago, I've been playing Roblox. While playing, I've realized I've been getting massive lag spikes out of nowhere. Confused, I check its performance settings tab and it says this:
FPS: 59.9/s
Physics: 60/s
Render: 60/s
Network Receive: 60/s 0.4 msec 4%
The strange thing that I'm noticing is that Network Receive is flashing between orange and red, so I've looked at my Internet speed a few days later and noticed Upload Speed and Bandwidth is lower than it typically was. Dropping to 3mbps for Upload Speed and around 4kbps for bandwidth.
Troubleshoots:
Restarted and unplugged Router and Modem multiple times
Tried the IP and DNS settings issues (one of those methods I believed because there were no comments debating the videos)
Uninstalled Roblox multiple times
Rebooted the console
