Internet connection down every 20 mins

[DPule1]

Hello, everyone

Today I asked my ISP to configure my modem/router as a bridge, and then connected a TL-WR541G (TP-LINK) router to manage ports and such.

Since then, after every 20 minutes Internet access goes down, I'm still connected (apparently) to the network, but with the exclamation mark and the legend: "No internet access" or "No network access". The only solution to this is to unplug the power supply, wait 10 seconds and plug it again. After that, Internet access is back. This generally happens every 20 mins, but it has lasted up to 1 hour with good connectivity before it goes down again.

The router has DHCP enabled, but I have a surveillance ip camera with an IP fixed to its MAC address (in order to let the port open correctly every time I reset the camera). The DHCP range, of course, doesn't include the ip fixed to the camera. Even so, I got a "two devices with the same IP" error a couple of times, even when this wasn't happening according to the connected devices list in the router configuration.

Modem: Motorola SBG901

Router: TL-WR541G

Connected devices: notebook (DELL Inspiron N4110, Windows 7), surveillance camera (TL-SC3171G), desktop PC, Tablet, 2 smartphones, Smart TV.

If any log or other information is required, please let me know.

Any help will be much appreciated.

Thanks in advance.

Hello misterious_guy,

If your wireless card came already installed when you bought your laptop, we highly recommend that you contact your computer manufacturer to see if they have any update for their drivers that might resolve the issue. Also checking router configuration might help. If you installed the wireless card after you bought the computer and if it is Intel's, you can check the link below that might improve your connectivity.

*Important to know: Integration, which is replacing the original wireless card that came installed in the computer when you bought it for another one, is not supported by Intel as this procedure is subject to regulatory approval and the adapter may not support local regulations. Only your system manufacturer is entitled to provide the list of validated and certified adapters that are compatible with your system so for more information you may contact them directly.

Hi, aleki_intel, thank you for your answer.

The problem is not limited to my laptop. I don't have internet access in other devices aswell when this problem occurs, so the issue is not related to the wireless card. It certainly has something to do with the router configuration, but I haven't found a solution yet and everything there looks fine to my inexpert eyes.
