I've been having crazy ping spikes in Roblox.

Hi Carlos B, my name is Jose and it is my pleasure to help you.

Just to check if the problem persists, can you create a mobile hotspot to share the internet from your phone to the PC? With this, we could see if the problem is your router or the account in general.

Note: If the ping issue disappears when you connect to your phone's mobile hotspot, it could be caused by your router or ISP. Is the router yours, or is it managed by the ISP? Try resetting the router and then reconfiguring it again, then try again.

Let me know if the mobile access point has temporarily solved the problem or if it still persists. I will be careful.

Greetings,
Jose.

This page has some useful steps to help with slow network performance:

@mikity: try searching for games with the DLC disabled(press select when you loaded up mp). also what is your upload and download speed?

you should find games between 75-100ms, if you don't then i would call my isp and have a line check up.

You realize doing a speed test while you are playing would be almost like running one while downloading a movie or something. Your game is eating up the bandwidth. Other games dont each so much.

Lag comp has absolutely nothing to do with your actual connection to the internet.

Best suggestion .... watch the search ping. Whenit hits 100, back out and search again.

Same thing here OP with the exception that my ping normally sits around 50.
