Hi, guys. I have a wr843n v1 router, running this firmware: openwrt-15.05.1-ar71xx-generic-tl-wr843nd-v1-squashfs.
There is a problem: My pc connects to the router and I can search the Internet normally. Several minutes later, I can not access to the Internet, although the wifi icon on the pc is normal. I ping the router, but fail. I have to reconnet the wifi, and the problem comes again.  The same as I use a mobile phone.
How can I solve this?  Have any good suggestions?

The problem came at 17:45 and below are the logs.

Thanks for reply. I use logread and find nothing. For example, I cannot access to the wifi at 14:37, but there are no logs at 14:37.

I would not look for messages at the exact time of the problem happening, problem might have started a few minutes before.

conanyangqun, check, if problem persists using wired connection. You can also compile and install last version of firmware. Yes, provide logs for a period -3 minutes, +3 minutes from the moment of loosing connection.

I have little knowledge on openwrt. The problem came again at 17:45, and here are the logs. Any good suggestions? Thanks.

conanyangqun, check, if problem persists using wired connection. You can also compile and install last version of firmware. Yes, provide logs for a period -3 minutes, +3 minutes from the moment of loosing connection.

The problem came again at 17:45 and Here are the logs. Any good suggestions? I am using the OpenWrt Chaos Calmer 15.05.1. Maybe I should sompile a new one.

I can't see anything strange. I've seen also forum message about WiFi problems with standard version Chaos Calmer 15.05.1 So I think, you should compile actual version of firmware yourself.

Thanks. I will learn how to compile.

Does it always happen after the "WPA: group key handshake completed" messages?

I did not notice. I will keep an eye on it and paste logs on here if I get some useful messages. Maybe it will help someone else.

The discussion might have continued from here.
