Have you already optimized your setup? That's where I'd start. make sure your gaming device is hardwired in.
Also, are you that good of a gamer that a little lower ping will help? If you're a casual gamer, a little lower ping might not be worth the cost. If you're a dedicated gamer who's dropped a bunch of money on equipment/gear, then it might be that extra edge you need.
Or if you're already needing to buy a router, then a little extra might be worth it.
If the gateway device can be set to a transparent bridge mode, then the XR1000 can potentially provide a benefit.
The main thing that determines if a gaming router will be of benefit to you, depends on your connection throughput, as well as what other activities go on while you are doing multiplayer gaming.
For example, you doing something like streaming a lot of video while gaming, or downloading multiple large files, or are running some cloud backup software, or do things like sync your local NAS with a remote one as a form of offsite backup, or really anything that will cause WAN saturation, then a gaming router will help.
If you rarely have other activity going on your network while you game, them from a latency standpoint, a gaming router will not help much unless you are running a game that has really poor matchmaking where it will pair you with people far from you where ping times with other players will be horrible.
In those cases, the XR1000 is useful.
I currently use it, and it offers a noticeable benefit in maintaining performance for gaming, as well as streaming. For example, making sure youtube gets enough bandwidth while I am downloading a large file.
Overall, it all comes down to having well implemented QOS where you can dynamically slow traffic that is more friendly to handling a slowdown. e.g., if streaming a 4K youtube video, then a drop from around 12Mbps to 10Mbps will mean lots of freezing and buffering, while having steam download Ark survival evolved download slightly slower while you are watching a youtube video, will not be much of a noticeable issue.
I have a modem one because the internet provider uses cable to being internet in so I have bad latency and lag with it right now and was wondering if I added this router to it and gamed off of Xr1000 it would get rid of lag and bad latency
The router would be able to solve two major causes of lag: Distance to game servers & local congestion. So in that way it can optimize your connection as much as possible. If you have inherent issues with the ISP then the router couldn't help with that. It might help make it more bearable but that issue would still be there.
