If you are seeing wifi connect but the Qolsys upgrade servers and Internet communication fail, that would usually suggest your router is blocking communication in some way.
You do have an old firmware version on that panel, but without internet connectivity with the update servers an updated version could not be applied.
One thing you might try as a test is using your smartphone as a hotspot and connecting your panel to the phone hotspot network. Do you get internet connectivity that way?
If so, it may be a good idea to try to update the firmware first.
