Hi, I need help with my problem. I own an Ultrabook LENOVO IdeaPad Flex2 15 notebook, which I bought about a year and a half ago. I noticed my problem with wifi after the purchase, but at that time I really needed a laptop, because the old one left and I had to write a bachelor's degree, so I didn't complain about it. The point is that connecting via wifi is a nightmare on my ntb, I live in a village and use the local municipal internet, which is free. Speed is not much, but when I connect via cable it reaches over 3 MB / s, which is plenty enough for work. On a mobile phone or other laptops, the speed via wifi is about 20% lower, unfortunately on my laptop about 90%, ie. that it runs at about 300 kB / s. As I wrote, I didn't solve it, I connect the laptop to the cable and it runs normally. But now I won't have the opportunity, I'm going to the apartment and I don't know if it will be possible to pull the cable there. I decided to try to solve it, I updated the drivers, at first it seemed to help, I even drove HD videos, but then it came back to normal. As for the driver settings (Realtek RTL8723BE Wireless LAN 802.11n PCI-E NIC), I don't know about it and I didn't want to "turn it off" even more. I would be grateful for the advice, please don't write me that I should have complained about it, I know, but back then I really needed a laptop to write. In addition, he has been there once and I definitely do not have good experience with the complaint center in Germany. Thanks for the advice :)
