Hello everyone! I'm using Lenovo Z50-70 notebook with Intel AC 3160 network card inside. I have a modem with 100 Mb/s download and I'm recieving download speed of 45 Mb/s on the notebook while my friend gets around 70 Mb/s on his ThinkPad. Has anyone else had this problem before? I tried to change bunch of settings in driver's settings according to some other forum posts from different sites but nothing helped.
I'm using Windows 10 64 bit. Driver version is 184.108.40.206
I really appreciate any help.

I'm sorry for not respoding for a long time, I was unable to get to my PC.
I attached the system information file into this message.
Also my router model is ZTE ZXDSL 931VII
It's likely that the slower download speeds are being caused by your adapter connecting at a slower rate to comply with your 802.11n router, plus it being a 1x1 model (one antenna supporting one data stream) as opposed to 2x2.
For optimal performance, we can recommend upgrating to a wireless AC capable router. However we do have some simple suggestions that could help while keeping your current hardware configuration.
We normally don't recommend using the 40 MHz channel width in the 2.4 GHz band, Channel Bonding could help increase your download speeds. The only problem is that it will also make you more vulnerable to interference.
From your router's menu, you'll simply need to change the "Channel Width" setting up to 40 MHz to enable channel bonding, or back to 20 MHz to disable it again, if it turns out to hurt more then it helps.

After this we can also switch your wireless adapter to a mode that will be more compatible with your router. For this we'll need to open the Device Manager from the Control Panel. Then we'll expand the Network Adapters category, and double click on your Intel(R) Dual Band Wireless-AC 3160 to enter the Properties menu.
Under the "Advanced" tab you will need to scroll down and set the "HT Mode" to "HT Mode." By default this is set to VHT (Very High Throughput), which enables Wireless AC. Lowering this setting to HT (High Throughput) may help decrease data loss when connecting to a Wireless N network.
Please let us know if this helps, or if you have any questions.
We're following up on your thread since we have not heard back from you.
Has your issue been resolved? Please let us know if you need any further assistance.
So the thing is, most likely my ISP has disabled changing Channel Width option in my router settings. I think that because I can't find that option anywhere.
Thanks for your help. Looks like I will have use my router as it is and that's it.
You're welcome. Thank you for you patience.
If you need any further assistance, please let us know. We're always happy to help.
What i found in https://guideusermanual.com/product-name-z50-70-laptop-manual&po=331389&lang=English Lenovo Z50-70 Laptop Manual is go to network connections and click on the wifi adapter. What is the link status and signal bar strength? Right click the adapter and go to properties. From there click on configure button and advanced button. In there switch it to performance and auto speed negotiation to auto if it's set manually or set it to just G only. Some wifi cards have very basic settings in there and some have a lot more. Some of those settings can mess with the link speed. Instead of 10/10 full duplex set to 100/100 full duplex etc. Maybe turn on/off packet offload etc
