I haven't tried a wired connection yet, it's a pain to do because of the router's location but I will try that tonight. I had tried to use a wifi analyzer app on my phone, which shows my 5ghz network at around - 50 to - 60.

When I did the fresh install, I ran a speedtest using fast.com with Edge and I got 220mbps. A few minutes later I'd installed chrome, and the speeds have dropped. I'm not sure whether the speeds dropped the way they were doing anyways, or if somehow installing chrome is the issue? I have restarted the PC a couple times and only run Edge to do a speedtest, and the speeds were very low. THe only two programs I've installed since the fresh system install are Steam and Chrome.



I'd tried to change some of the WiFi settings, so changing from "auto" channel to specific ones, trying the "low" vs "high" setting on the 5ghz network, changing from a/n/ac to n/ac etc. I changed everything back to what I'd found it as - nothing seemed to work in any case but as you can probably tell I don't really know what I'm doing.

Chrome reducing speeds like that is definitely a coincidence. There is no way it could have that sort of effect.

The drop is some sort of throttling applied somewhere along the chain, whether that's your ISP, your router, or your hardware. Given what you've tried, it might be worth speaking to your ISP and seeing if they can find any issues their side.

I will post my doubt again:

I currently have the following build and I have a 1440p 165Hz monitor as of now.:

- Intel Core i9-10900K
- Asus ROG STRIX Z490-E GAMING ATX LGA1200
- G.Skill Trident Z Neo 32 GB (2 x 16 GB) DDR4-3600 CL16
- ADATA XPG SX8200 Pro 1 TB M.2-2280 PCIe 3.0 X4 NVME SSD
- Gigabyte GAMING OC GeForce RTX 3080 10GB
- be quiet! Pure Base 500DX ATX Mid Tower Case
- Corsair RM850 (2019) 850 W 80+ Gold Certified Fully Modular ATX Power Supply

I don’t know why but it struggles with MSFS2024 so I was thinking on a new build similar to this one:

- AMD Ryzen 7 9800X3D
- ASRock X870E Taichi Lite EATX AM5 Motherboard
- Acer Predator Vesta II RGB DDR5 6000MHz 64GB 2x32GB CL30 Plata
- Gigabyte GeForce RTX 5080 Gaming OC GDDR7 DLSS 4 (I cannot justify the overprice of almost €1,270.00 for a Gigabyte AORUS GeForce RTX 5090 Master)
- Acer Predator GM7 2TB Disc SSD 7400MB/S NVMe PCIe 4.0 M.2 Gen4
- Corsair HX1000i 1000W 80 Plus Platinum Modular or Corsair HX1200i 1200W 80 Plus Platinum Modular
- NZXT H7 Flow 2024 Cristal Tempered USB 3.2
- Be Quiet! Pure Loop 2
- NZXT F280 RGB Core (is this needed?)

I'm doubting on whether going for a new build or upgrading the CPU, GPU and RAM of the existing one. If I go for the new build, is it a balanced one?

Unless you have it in hand a 5080 is going to be difficult to come by. You may want to wait and see how the 9070XT performs.

If you can find a 5080 it will (likely) be the better performaning card.

I agree re Chrome, I expect Edge would have shown the same speed reduction after a few minutes as well.

Re: the ISP point, does that still apply if all my other devices are running just fine? Phone, laptop, smart TV and everything else runs at healthy speeds without any interruption or issue. I also forgot to mention I tried using my phone's hotspot network, with the same results.

Tonight I'll be looking into BIOS settings and trying an ethernet connection.

Ah, I forgot about the other devices. I don't see how or why your ISP would limit for one device, so that's that possibility crossed off the list.

I'm now home with a chance to do some proper googling, and found a few bits that may be of use. Some suggest Windows/drivers could be the culprit.

Redirecting

If the fixes in the above link are of no help and nothing stands out in the BIOS, then it might be worth setting up a USB stick with Linux on as an alternative OS to test with.

Question - Could a BIOS update throttle USB wifi adapter download speeds?

Hello all! Apologies if this is posted in the wrong area, I'm really unsure who could best help. I'm really at a loss trying to fix this particular issue I've been having, with no luck looking elsewhere on the world wide web. The thread title may seem ridiculous but I'm so frustrated and out of...

This link from last year suggests BIOS won't be the issue, but that it could be a physical problem with something causing interference with your WiFi receiver(s). Replies also have a Powershell script that fixed that guy's problem.

[SOLVED] - Issues with internet speed capped at 100Mbps and possible solution

I have 300MB connection and didn't noticed any limitation until today after I formatted my PC and reinstalled Windows 10, the speed was capped at 100MB afterwards (downloading at 11MB/s maximum). I thought it could be something related to drivers so I formatted again and manually installed the...
