Wireless router TL-WR841N wifi network randomly dissapears
Hi.
I set up the TP Link wifi router connecting to my ISPs router via an internet cable on the blue connector.
Then, I am connecting to the router's wifi via my laptop.
My laptop runs linux.
I can connect successfully initially.
However, i notice that, after a random while e.g 20 or 30 minutes, the wifi network of the router "disappears", even though my PC is still connected to it.
I have looked for the wifi network then using my phone, and it can't be found.
In order to get the router wifi network to re-appear, I have to power cycle the router.
If i had to guess what is happening, I would say there is some kind of a time-out happening in the wifi hardware, which is switching off the wireless network identification after a while, so it becomes invisible.
This behaviour is a pain, as I have to do a reset every now and again.
When I connect to the router via a cable, I don't experience these network problems.
My questions are:-
1. Any idea what is happening ?
2. How to trouble-shoot the problem ?
