Unstable wifi in Arch

I run i3 on my system i have a Ralink RT5392 wireless card and i have faced so many issues with stability starting with under an hr stable time before Network Manager would tell me "activation of network connection failed" and then not let me connect to the internet i tried a few things the more common of which being disabling random MAC-address randomization, removing DHCPCD, and disabling powersaver. These issues have helped extend the uptime of my system but not permanently fix it. Once it stops working i have to restart my system in order for my internet to work again a few outputs that might help are lspci which give s

the important part being  "03:00.0 Network controller: Ralink corp. RT5392 PCIe Wireless Network Adapter" iw dev and ip link say my wireless card is up when i lose wifi but some reason i can't get it to work at all.
another useful output is systemctl list-unit-files --state=enabled which gives
UNIT FILE                                  STATE   VENDOR PRESET
autovt@.service                            enabled disabled

NetworkManager.service                     enabled disabled     
remote-fs.target                           enabled enabled     

9 unit files listed.
so nothing helpful any ideas?

Re: Unstable wifi in Arch

One thing you could try is to format your post in such a fashion as to make it readable.

Things like [ code ] [ /code ] tags to wrap and separate output so that it doesn't all run together.

You could use spaces and punctuation and the like.

I don't know about anybody else but walls 'o text give me a headache.
