And just in case it's running on the TG797 modem too(I think).
My apologies to all.. trial explanation here---
There are 3 separate systems running here,,
House NBN modem downstairs.
Upstairs is my repurposed W7 machine connected to house modem via wireless.
Upstairs on fridge qnap with TG797 attached. The tg797 is connected by wifi to one usb dongle on W7
Hopefully that scrapes some mud off  
Sounds like you're using that TG797 modem(in the image) as a wireless link to the home network? 
No. see above.
No, wireless to
When you say 'house modem' this sounds like the main modem connection to the outside world AND your home network too? ... but not the same one as the TG797 connected to the NAS?
 Correctamundo!
And I'm confused as to the purpose of the second USB adaptor to the NAS.
The 3 seperate systems need two dongles upstairs to function. At least the interweb told me I cant run two wireless inputs into one dongle?
The simplest way to connect the NAS wirelessly to the rest of the network would be to have it connected via cable to the main router for the entire home network. 
Agree but not feasable.
It requires no other connection other than the power cable. 
From there, you can do anything else you want with or to it.
Only other suggestion would be to fix it's IP address in the network to, by setting it in the router. 
backburner for the moment
If you can't physically do that and you're trying to connect it wirelessly via the TG797 device(in the image), then the TG797 has to be set to bridge mode or wireless repeater mode or whatever with almost all other routing services off(which the main house router/modem).
If you could do a sort of diagram-ish thing of the network topology of how it's connected/connecting.  
You wish! LOL!!
The other question which seems open to interpretation here, is: are you using a USB wireless dongle on the QNAP too?
