I have a 300mbit/s internet connection and I actually get bit faster since I download from steam around 40Mb/s when using my desktop computer and ethernet. My problem is that when I use my laptop and wifi with the same modem, the download speeds are way slower than they are supposed to be. I get about 3Mb/s speed when I download from steam on my laptop. It is only few months old laptop, wifi signal is good and windows 10 says it is using 802.11ac and 5Ghz. I am also testing it having the laptop right next to the modem and nothing between them and also no other wifi devices connected to the modem. Still I am only downloading 3Mb/s. Laptop gets the same speed as my desktop computer if I connect the ethernet cable to it. The modem is Technicolor TC7230.
Any ideas how to troubleshoot the problem and what reasons there could be for such low download speed?
Have you looked to see if you are running the latest firmware on your modem and the latest wifi driver on your laptop? Also, could the modem be stuck in eco mode?

It looks like you're mixing up your units. Based on your description I'd suggest you have a 300Mb/s Internet connection and you can download 40MB/s, which is 400Mb/s, from your desktop. Your WiFi might be downloading at 3MB/s, which is 30Mb/s. That's 10x slower, so not good, but not the apparent 100x slower you seem to be suggesting. – roaima – 2018-07-23T07:52:22.070
I try to look into if there is some kind of eco mode in modem settings. I wasn't thinking that I was suppose to get 300MB/s. I am paying for 300mbit/s connection and I am getting 40MB/s which equals 320Mbit/s using ethernet which is pretty good. I still think 3MB/s (24mbit/s) is too slow wifi connection when device is right next to the modem. – Belasan – 2018-07-23T10:03:47.557
I found something interesting in the 5Ghz wireless settings. There is 3 options for bandwidth 20Mhz, 40Mhz and 80Mhz. The setting has been set as 80Mhz, but the modem still says "Current: 20Mhz". Not sure why it uses different bandwidth than what it has been set to. – Belasan – 2018-07-23T10:26:38.100
