Tell me the solution to the problem.
It was a router from D-Link, has been losing a connection, I thought it deal changed at TL WR740N, the problem persists.
Became sin to the provider (residents near Moscow know what Telinkom), but it was not in it, because lost to communicate directly with the router.
The level of signal may be the maximum, but even 192.168.0.1 will not open.
Tried to hang on the free WiFi channel and gertsovku changed, nothing helps.
The problem occurs on multiple devices (of course at a time).
It helps only restart the router.
The firmware version on the screen.
