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?

Did you check for firmware updates for the router? Or search to see if this is a common issue with this router model? –  CharlieRB Jan 3 at 15:04
    
Yes, before I asked this question I had installed the newest firmware from tp-link.com.pl/support/download/… I could not find any similar issues in the web. –  Wojciech Frącz Jan 3 at 15:36
    
You should update your question with that information so others know what you've done without having to ask. –  CharlieRB Jan 3 at 15:37
    
when LAN stops do you mean Wi-Fi or Wired connection? If only Wireless you should connect PC to it using network cable and check the settings. –  Vladimir Oselsky Jan 3 at 20:22
    
Have you also reset it to default via software AND the hardware button it has? Sometimes they just get stuck in a bad state... I checked and it is not listed as supported by dd-wrt so that option is unfortunately not available. –  Andrew M. Jan 22 at 23:17

Heat can make a failing device worse. An easy test is to open the case (if possible), blow out any dust and use a regular house fan to cool it.

If that works, I would suggest replacing the unit soon. Sometimes the fan will buy a little time though.

I have also seen devices fail because of low temperatures. Utah is fun like that! –  Andrew M. Jan 22 at 23:49
