Orbi Pro (SRK60) Wifi problems with online gaming

It sounds like you may be experiencing issues with your Orbi Pro router and fiber-optic internet connection when playing online games like car parking multilayer. While your internet speed is good, the lag and difficulty connecting to game servers suggest that there may be some settings that need to be adjusted on your router.

One thing you could try is to prioritize gaming traffic on your network by enabling Quality of Service (QoS) on your Orbi Pro router. This will ensure that your gaming traffic is given priority over other types of traffic on your network.

Another setting you could try adjusting is the channel width for your router's 5 GHz band. Some gaming devices may have trouble connecting to wider channels, so you could try adjusting the channel width to a smaller setting to see if that improves your connectivity.

Finally, it's possible that there may be some interference in your area that is affecting your wifi signal. You could try using a wifi analyzer app to check for any competing wifi signals on the same channel as your Orbi Pro router and adjust your channel accordingly.
