Good internet on a PC. Poor quality at x360, high ping

Actually, your ping is fairly high for 50 miles, and could be part of the problem. Check first what others said about usage on your network.

But with a 94 ms ping, you are probably getting put in lobbies with 100 ms ping ...... and your single bar connection is the result of your poor pings coupled with the host having a poor connection.

I'd start doing some frequeny pingtests, and if they are constantly that high I'd be talking to my internet provider.

From what I understand, it's the fault of the Developers. They created a Match Making that intentionally groups Players with terrible Ping Rate to Players that have high to excellent Ping Rate in order to compensate for those
that have a poor Internet Connection speed.

Low ping = good.

The 'bar' is not ping, it's the general quality of your internet connection, and a latency timer. The higher the latency, the higher the ping, the worse the connection is, the lower the bar will go. I'd do a speed test on an internet browser to see if it's
your internet connection or not.

Ping is a signal sent from one computer to another. The time that ping takes to make it's trip we call latency (quality). So a high ping latency will cause lag. The good news is this is very rarely down to a fault with your Xbox. The problem will be with
your ISP or your internet equipment such as your router.

There are several things you can do to try and rectify a high ping. You can start by turning off your router and unplugging all cables from the back of it. Leave it for 5 minutes and then plug it all back in.

Get back to me if that doesn't help and we'll try some other stuff

Can I ask who your ISP is? (internet service provider)

The mic it's working, but his quality is poor on any game or app on the PC, I had another headphones wired and those had a good quality mic so it's not a PC issue
