help haveing issues with a dell r520

Hello fellas, I'm here because I'm having very odd issues. I'm going to tell you about my network, how things are set up, and what I've tried or haven't tried. I'm also going to upload my logs just for fun, but I don't see anything abnormal. But anyways, I have Bell Internet going into my Opnsence firewall using PPOE, then from the firewall to my Netgear XS512EM 10 Gbps switch. Here is the issue: Bell isn't a normal modem. It's a modem/router combo, and even trying to figure out how to connect that is iffy. I heard I could use PPOE, and then I was told I could only use an XGS-PON or one of these:  or any of the network https://www.heyoptics.net/products/xgs-pon-10g-10g-onu-sfp-n2?fbclid=IwAR2sKorbYa1fcmR2GoJX0P8iWrVt5boeAhxLUp_DtHiRw41cMKMwME7A2l  Anyway, the tech that came out to my house did say it could get randomly disconnected if I use PPOE, and I really think this may be the case, but I would eliminate the modem entirely. Here is the issue: SAB is randomly disconnecting. which is odd, but anyway, the internet is still up because I'm remote-controlling the computer, and it never affects me. I'm remoting it from work, and I was thinking if it really is a connection issue, like the house is shutting down and popping back on, it would disconnect me. Just a very dirty test, but anyway. I have tried a new Cat 6a cable and a memory test, but I read somewhere that the memory test can't tell the difference if the ECC is bad or not. I have no idea how untrue that is. But if it isn't true, then I have two well-known sticks in the system. Also, this system came with like 120 GB of RAM, and when I had all that in there, it would randomly disconnect, even worse than it is now. I also changed out the HBA card, thinking that it had a bad flash. Also, are there any BIOS settings I should turn off? I'm starting to wonder here because it feels like I'm beating my head against the wall and I'm very unfamiliar with Dell servers. Oh, and I also have this, for which I have no clue if it matters or could be a problem or not. mcelog: Kernel in lockdown Cannot enable DIMM error location reporting. Oh, and when Sab disconnects, it like laggs out the entire Unraid server, like if I have Radar open and Sab disconnects and I refresh Radar, it will lag out until I reconnect, like I said. Also, there is a 10 GB card in this, as well as a P2000. Nothing strange, and I'm using the mini-something HBA card that I flashed. But I was quick enough to hit refresh and do an internet speed test because I was ready for it, and the internet didn't skip a beat; it was 3G down and up. So it's like Unraid or that Dell is just disconnecting for some reason, which is why I'm not convinced it's the PPE or Opnsense.
