I have a TP-LINK router. Newest firmware (Firmware version: 4.7.11 Build 101102 Rel.60376n, Hardware version: WR340G v3 081520C2). It has connected cable from ISP to the WAN port and broadcasts the Internet via WI-FI in my house. I have a few computers / smartphones that use it.
The problem is that after a few hours of work the LAN network stops working (devices don't see each other, on wireless connection). However, the Internet still works. I cannot use wired connection as all of my devices are laptops / smartphones and it will be highly inconvenient.
When I try to enter the router configuration page, it does not respond. Even
ping 192.168.1.1 does not work (waiting time exceeded). Pings to other devices does not work too.
Network configuration (on a host that I'm working right now):
IPv4 address. . . . . . . . . . . : 192.168.1.100 Subnet mask . . . . . . . . . . . : 255.255.255.0 Default gateway . . . . . . . . . : 192.168.1.1
The LAN network "works" for a few hours after I reboot the router by switching the power off and on.
Is there anything I could try to do instead of replacing the device with a new one?
