Ethernet Speeds Capped on Acer Predator Helios 300 2019

Hello,

I just received a new Acer Predator Helios 300 2019 (PH315-52-78VL) from Amazon. So far I have LOVED this laptop. It is a huge leap forward compared to my ancient 17.3" MSI GT70 from 2012. However, I seem to be having some issues with the Ethernet. I noticed I'm only getting up to 100 Mbps speeds with my new laptop. I know it is not the cable or internet connection because my old laptop, using Ethernet, gets speeds up to 700 Mbps.

Looking in Device Manager at 'Advanced' tab for the 'Killer E2500 Gigabit Ethernet Controller,' I see that for 'Speed & Duplex,' it is set to 'Auto Negotiation.' The max value options are '100 Mbps Full Duplex' and '100 Mbps Half Duplex,' which are 1/10 of the claimed gigabit speeds. Does anyone know why this is happening? I really want to like this laptop but I do big data transfers over Ethernet all the time, so this is a deal breaker.

Thanks!

Sincerely,
Exper1mental

Hello man i just read your problem and i have the same one here
if you got any solution please help..

Since I was still in the returns period, I ended up returning the unit (which also had some minor physical damage) and exchanging it for another unit instead of sending it in for repairs.

If you’re having this issue and outside the return window, I’d talk with support and follow the steps they suggest. If what they recommend doesn’t work, after trying other options they should eventually ask you to send in the unit. Patience is key in getting to this point.

Hope that helps!

UPDATE: I contacted Acer via chat support.

They told me to open a Command Prompt (Admin) and run:

netsh int tcp set global autotuninglevel=disabled

This did not work (including after waiting the 2 hours they said it might take to have an effect), so they are having me send the unit in for repairs. I thought I'd pass this along in case anyone else has this issue in the future.

It's quite strange to tell you that my G3-572 from 2017 has "1 Gbps Full Duplex" option in Device Manager.

On the Killer website, they say that "1 Gbps Full Duplex" should not be an option with their network adapters. They say 1 Gbps can only be achieve using 'Auto Negotiation'. Very strange stuff.
