The situation is this. A private house. There was a router
TP-LINK TL-WR940N . The speed from the provider is 100Mb / s to receive and 100Mb / s to return with a cable connection from the router to the PC with a PING of 2-8ms. A laptop in 7 meters behind one wall was also connected to it simultaneously via WiFi (measurement
http://www.speedtest.net/my-result/6412884390) , tablet and two smartphones at the same time. Everything works well. But as soon as the Asus laptop is connected (let's call it
note2 ) (Win7 Ultimate x64) at 20 meters in the next annex, then the connection on other devices starts abruptly. This is manifested in Skype: voice communication breaks into syllables; opening web pages or any video on YouTube with a long upload. At the same time
note2 YouTube is viewed (maximum 720p) and web pages.
What was done . If you turn off all devices and leave
note2 and one or the other, the hangup continues. Updating the router software and its migration did not help.
Note2 has been tested for viruses
DrWeb CureIt, Kaspersky TDSS Killer, adwcleaner, Malwarebytes Anti-Malware, Eset Smart Security, All autoload and scheduled tasks are disabled. Changing the channel does not give a result. Within a radius of 50 meters, there are no other WiFi networks.
Also
the router has been replaced on
Mi Router 3 (R3) (for verification) with international firmware Stable 2.10.38. There are no restrictions on the number of simultaneous connections. The situation has not changed. That is, when connected to the network
note2 , the use of the Internet becomes impossible. Although right there when checking for speedtest speed and PING are normal. Forcibly disable (block)
note2 everything is normalized.
I have not tried to update the driver for the adapter
note2although updates for the OS come and are installed or, for example, reinstall the operating system.
A similar situation with a friend (another provider). His father has a LG smartphone. When it connects to your home WiFi network, the Internet hangs on a smart TV, computer, smartphone.
As if the channel was clogged ... There are recommendations and considerations on this subject, or it takes an extra. information?
