I'm having a major issue with my Wi-Fi. My brother's connection is solid, but mine is terrible, and we're practically sitting next to each other—I'm about 4-6 meters from the router, and he's only about 2 feet away. We don't use Ethernet, and all other devices in the house, including my phone and VR setup, work just fine. My computer, however, is consistently lagging with about 300 ms ping. I've ruled out overheating as a cause since my PC stays cool, and it doesn't seem like there's any limiter on the connection, based on advice from my dad. Plus, when I run a troubleshoot on my computer, nothing seems to be detected. Any advice on how to fix this?

Are you both connecting using Wi-Fi 6? Also, check your Wi-Fi adapter. Is it properly secured, and what kind of antenna orientation are you using? Sometimes it's all about those small details, even the frequency you’re connecting at matters!
What kind of devices do you both have? I mean, like, what's your operating system? I see you're on Windows 10; what about your brother? Also, what's your internet provider and what model router are you using?
There's a ton of factors affecting your Wi-Fi. Things like furniture placement or even the materials in your walls can really disrupt the signal. It's frustrating, I know! Just keep in mind, Wi-Fi is usually about convenience rather than performance.
I've noticed some kids' computers struggling with slow Wi-Fi due to background updates. If you have lots of streaming or devices connected, it can overwhelm the router. You might want to check if any auto updates are running in the background!
It could be a crowded Wi-Fi channel. It might be worth checking your router settings to see if you can find a less crowded channel. Just a thought!
Have you thought about switching to an Ethernet connection? It's usually the best way to ensure low ping and a more stable connection. It might help you out a lot!

I have Windows 10, and my brother's using Windows 11. Not sure about the ISP, but I do know my router is a TP-Link Wi-Fi 6E.
