Model : TL-WR841N

Hardware Version : V9

Firmware Version : 3.14.4 Build131129 Rel 39318n

ISP : Digiweb ltd

Hi,
I have TP-LINK cable router TL-WR841N. It randomly drops the internet connection for 10-20 second and it renews the connection itself.
Here is my condiguration.










Is it ok, that TP-LINK requests new IP address from wifi antena on the roof every minute? Please see log file:
Is my configuration correct?
When I connect my laptop directly to the Antena (located on the roof), there is no any problem no internet connection drops.
Thanks you for help.

Firmware of your WR841N is old...
Download the latest firmware and upgrade it. Reset and reconfigure it.

I did, but it is still happening.

watching video file




Downloading file




The time in the log file is not correct. 11:11:00 on the chart when connection was droped is approx. 0:20:00 in the log file

Syslog(6).txt


Any suggestions?

UPDATE:
When I turned off DHCP filter, (antenna unit managed the IP addresses), the internet connection was not dropped. It worked well. So it seems to me, there is an issue with the DHCP server on this router.
