I updated my machine manjaro x force and wifi card isnot configured any more …so how to downgrade ?or what is the solution?
Is this meant to be XFCE ?
We dont have any information.
Downgrade is a last resort, and we wouldnt even know what to downgrade.
Instead maybe we can start with:

Any other commands?
So: what got updated?
A new kernel?
Try installing a newer one - or simply a different one from those that are available
and then use this.
The wifi driver should be part of the kernel.
From the outputs you provided:
your system does not even see the presence of any wifi hardware.
it’s simply not there
The card might be switched off (some laptops have a hardware switch)
or it might have come lose and lost connection, or it might simply be broken.
Easiest is probably to boot the same live system you used to install from and see whether it still works there like it has been.

If that real tech wifi was using a dkms driver try:
sudo dkms autoinstall
then reboot.
If it wasn’t it will just show an error. I had a problem with my dkms package at the last stable update and I noticed a fair amount of similar realtech wifi issues afterwards. Worth a try.

Actually from two it worked then again the issue happened…there is no issue in Hardware
I update every thing sudo pacman -Syu
I don’t comprehend what that means. 
Good that you know that - yet your outputs do not even show the mere presence of any wifi hardware.
I didn’t see any anyway …
lsusb
might show it - the device may be on the USB bus
but that should have shown up in the inxi output above
When looking at the machine type - we are looking at a firmware dated July 18. 2011 and a CPU built 2010-12 - being that old it is safe to assume that drivers are present with Linux
It appears your system has a Atheros AR3011 Bluetooth
WiFi and Bluetooth usually comes on the same card although that may not be true in this case.
From the info on rfkill it appears your device is powered down by hardware switch.
I suggest you look at the top keyboard row and locate the key for the wifi toggle - it may also be a separate key or touch area above the keyboard.
Don’t ask me which one - or where - I have no idea - but since you claim it worked - I believe you have - by accident - hit the hotkey combination disabling your wifi.

before it was happened then I just press Fn+F2 and usually worked but now nothing is happening , I will try to upgrade Kernal
Sorry, the realtec component was the ethernet adapter, I missed that.
I found a hw probe of a matching inspirion 5110 that shows an intel centrino-n wifi adapter: HW probe of Dell Inspiron N5110 #3f21759342 (the Qualcomm atheros might be a usb device)
If that’s correct this might be a problem with the intel centrino iwlwifi driver.
There’s a Bios setting to enable/disable wifi, please check it’s on. (Sometimes a weak cmos battery can cause weird changes of values)
