After restarting, pc can't recognize router and LAN led is off, so every time I must restart router.
There are no problems with WAN and WLAN.

Reset the router to have a try. By the way, does this happen to all your computers?
I’ve already tried that.
It is the only computer.
I think that is something wrong with cable (wired connection) or with network card in computer.
I don't know, all cables and network card are working fine without router.
I replaced router with new one, but problem persists.
This is my router configuration, you can check it - LINK
how about using a static IP address with the particular computer?

These settings are wireless related and I don't have problem with it. I can always connect phone or tablet.

It sounds unreasonable that router's LAN ports don't like PC's ethernet port.
Did you try all the four LAN ports with your PC?
I think it could be a problem of the cable you use, or the LAN port on the router, also the ethernet port on your PC. I do suggest you test with another laptop. If you have the same problem with the laptop when it is connected to router's LAN interface, it probably is a hardware problem on router's LAN interface.
TL-WR740N Router looses WiFi connection and needs reboot/Restart to connect
I have purchased the TP-Link TL-WR740N router on 6th April 2013 at 8PM from a consumer electronics market. At my residence i already have a 2.4 GHZ SMC a/b/g router with speeds up to 108mbps on Super G turbo dynamic/static modes but i wanted to upgrade it with a new latest low budget N150 router. I have heard a good reviews of TP-LINK and hence selected same as it was also fitting right in my budget.
I came home and installed and configured the router as soon as i reached home on Saturday. The router worked fine for few minutes and then it lost connection. Though when i scanned for the router on my mobile phone it used to appear in the list and i was able to save it by putting the WAP security key. After saving it when it tried to obtain IP address it showed an error " Authentication error occurred". So i deleted the router from the list and again searched and tried to connect by inserting the WAP key but it again showed the same error "Authentication error occurred". I have a wireless adapter in my desktop computer as well so i scanned for WiFi networks and i was able to find my TP-LINK router but it did not connect. Then i connected the RJ45 cable from my computer and hard wired it to the router and it worked. I was able to connect on internet and also open the routers management page 192.168.0.1. but when i removed the RJ45 cable neither the internet nor the 192.168.0.1 page did nott worked even when the WiFi led on the router was glowing green.The only way to connect wireless was to either Reboot or power off and then Power on the router. Please note even if i don't reboot or power cycle the router i was able to go to internet by physically connecting the RJ45 cable to the router.
Please help on this issue as the WiFi is only a day old and i am experiencing problems with it. I have already tried reseting the router couple of times to factory settings and as well as updated the firmware to latest version i.e TL-WR740N_V4_130322 from the TP-LINK website but that did not help. Also i tried calling the technical support whole day yesterday but nobody was answering my call.
Hussein, where are you from?
Can you plz mention what is hardware version of your router?
As I already said, I tried everything.

After all, I think that problem is RTL8111B PCI-E Gb LAN controller on ASUS P5LD2 SE, but it works fine without router.
Hussein, from your post, i am a bit confused..
1. " Authentication error occurred". This authentication error occurs when you remove the network from the list, search the network, when it appears, connect it and enter the WPA key...I am wondering have you entered the correct password? such a stupid question..But you'd better make sure the case-sensitive wifi key has been entered correctly.
2. "The only way to connect wireless was to either Reboot or power off and then Power on the router" It seems you can successfully connect to the wireless network. But the connection drops out? How many wireless client do you use to connect wifi at the same time?
