All of a sudden, I couldn't connect to my wireless connection. What is going on?

I've had my Xbox since November 2022 and I've always been connected to my home's wireless network, no problem. Today, I got on and noticed I couldn't use anything that required for me to be online. So I went to setting to try and see what was up. I wasn't connected. The reason it was telling me was that my network wasn't set up. Mind you, the Internet was working just fine on every other device in the house, including my brother's Xbox. I've troubleshooted and everything, but nothing has worked. I tried adding a wireless connection because my Internet thing wasn't available, so i put in my SSID yet it didn't work and it said to restart my wireless connection. I continued to do that and it still didn't work. It then asked me to see if my MAC Address was being filtered out by my modem and it told me to go to xbox.com/networkhardware to find out about filtering MAC Addresses and on how to change it. I continued to the website and searched every variation of the question i was looking for, yet found nothing. At some point I decided to clear my MAC Address, which seemed to work for a second. I was connected to my Internet but the wireless connection kept switching between "could not connect to wireless connection" and "connected". I restarted my modem as it asked me to, which then left me fully unconnected. I recorded my MAC Address to see if I could get what little hope I had left back, yet nothing happened. It says I have 2 hardware problems. I've searched endlessly through the website, I've called Xbox support, I've ran so many tests, I've troubleshooted, yet nothing. It just randomly started doing this, it was completely fine yesterday and the other days I've used it. I've never had this problem before. I'm considering on just trading it in for a different Xbox because I've got a 1 year warranty on this, but I wanted to come here to see if there was any hope or chance I could save or fix my Xbox. (I do have an Xbox one, it is one of the older ones because it's bigger, as I've previously mentioned my brother has one of the newer Xbox one's as it is smaller.)
