Laptop loses Wi-Fi

Question

WiFi

When connected via 802.11n, the laptop periodically loses the network (more precisely, the network remains, but the signal drops, and the speed drops to zero). When switching the wireless card to g-mode, everything is fine. (Plus, even in n-mode, windows shows a maximum speed of 150 Mbps, although the access point adapter (ZyXEL NWD2205 EE) supports 300. Encryption costs AES).

Notebook: HP Pavilion dv7 6152er
Network card: Intel Centrino Wireless-N 1030 BGN 1x2 HMC WiFi/Bluetooth Adapter.

Answer 1

I don't know if it will help, but I had a similar "problem". It manifests itself when downloading large files in utorrent.
The reason turned out to be that during a fast download, utorrent does not have time to reserve space for the file and writes something like disk overloaded. After half a minute it lets go and you can use it again. Everything looks so that the connection with the Internet has fallen off, while the laptop seems to be working normally.

Answer 2

1) Install the latest drivers from Intel
2) I saw how Wi-Fi fell off on Sony laptops when Bluetooth was turned on. Try to work with Bluetooth turned off
3) Download a program for monitoring Wi-Fi networks - to show which networks hang on which channels, what is the noise level. It is quite possible that the “failures” coincide with the fact that the neighbor starts downloading a torrent on the same channel or talking on a radiotelephone. Manually correct the channel on which your network works
4) If nothing helps, try changing the type of network encryption
300 Mbps, most likely, your adapter in your laptop does not support.

Answer 3

Here in the settings, select 40MHz.

Answer 4

If the problem only occurs when running on battery power, check the network interface settings. It may have a power-saving mode in which a large percentage of packets are lost. I had the same problem, disabling power saving mode helped.
