Hi
I am using Manjaro Linux over an old HP Laptop (HP Pavilion G6 2298SE). This Laptop has following Network Adapter:
Code:07:00.0 Network controller: Ralink corp. RT5390R 802.11bgn PCIe Wireless Network AdapterThe problem is that I am frequently being disconnected from internet (4-5 times a day). When this happens then the NetworkManager shows no wireless connection in its list. After disconnection, the "lspci" shows the Network Adapter in its results. However, "ifconfig" does not show the Network Adapter in its result. And "journalctl -xe" show following messages at the instance of disconnection:

Aug 07 16:18:54 pc systemd[1]: Starting Network Manager Script Dispatcher Service...Few months back, this used to happen rarely (once a week or bi-weekly), but now the problem is more frequent (4-5 times a day). In order to fix it, I have to reboot my Laptop then the Network Adapter again started to work fine (for a while).
So, the question is that: Is my Network Adapter dying? or Is there any other problem with it (driver, power management etc.)?
Can you help me in this regard?
