Weird internet issue.

[Graverage]

Hey everyone, hoping you guys might be able to help me as my ISP and I are a bit stumped atm.

 

So for some reason using something like speedtest shows about double the amount of download speed I am supposed to have, but my ISP sees the correct download speed (upload is fine on both ends).

 

This came about as I've been having some internet issues recently and was hoping it was my ISP and not my new motherboard, however with this odd difference it's becoming more clear that it's probably my motherboard.

 

I have disabled quite a few "offload" settings and it seems to have mostly fixed my internet issues, tho not completely as I still get some odd lag here and there when playing games or watching Twitch. It's as if my internet just stops working for a few seconds.

 

Hopefully someone here are able to help, or at least have some suggestions that I can try. Can unfortunately not test with another PC as my laptop doesn't have an ethernet port.

 

Motherboard is Gigabyte X570 AORUS ELITE

 

Speedtest is showing 500Mbps.

What CPU do you have?

My 3700X can only use 900mbits of my 1000mbits download rate because it gets tanked at 100 % when downloading on steam.

That's unrelated to actual bandwidth. Steam compresses the game so it uses less bandwidth, so your CPU needs to decompress the download in real time. Apparently 900-1000Mbps is the fastest your 3700X can decompress steam's download.

 

With a normal speedtest, it's not a matter of CPU resources.

Thats what i meant but failed to formulate the right way .

When runnin speedtests i get 1000Mbps, its just the decompression bottlenecking my downloads on steam.

I find issues like these to be more router related than issues with the computer NIC. How old is the router provided by your ISP?

My router is a few years old by now, at least 4 years.

Yea I would be suspicious about that thing then. ISP provided routers are typically cheapy made, even if they're manufactured by industry leaders like Cisco. I've told this story a few times on the forum before. But I had a conversation with the technical support team for my ISP when I was having issues of internet periodically going down. And the guy straight up admitted yea, these routers are not great for reliability and these issues will pop up after one year of service. And for good reason, cheaply manufactured devices that run 24/7 on end, it's about what you would expect. If I were you, I would see if you could get a replacement router first and see if that resolves your problems.

I will try that. Thank you for the quick reply.
