Issue: Wi-fi connection drops every hour and now can't be found anymore, but internet works with a cable.
I was recommended by D-Link support team to update firmware but when I'm trying to do that it shows me the error message:
-------
Invalid upgrade file!
Please make sure you have correct file.
(Error code: -150)
The device is rebooting...
Please DO NOT POWER OFF the device.
-------
Where can be the problem?

- Are you wired or wireless connected to the router?
Always be wired to the modem when doing FW updates.
Web Browser Configurations
What browser are you using?
Try Opera or FF? If IE 8, 9, 10 or 11, set compatibility mode and test again.
Disable any security browser Add-ons like No Script and Ad-Block or configure them to allow All Pages when connected to the router.
Clear all browser caches.
Be sure to log into the Admin account on the router.
Try turning off these features in Chrome:
Top right corner, little bars for options > Settings > Settings (on left) > Show advanced settings.
Uncheck these:
Use a web service to help resolve navigation errors
Use a prediction service to help complete searches and URLs typed in the address bar
Predict network actions to improve page load performance
Enable phishing and malware protection

- Ensure the default (dlink) SSID name is changed. Can be anything and not something that's already in use by any neighboring WiFi routers. Under Setup/Wireless/Manual.
- What wireless modes are you using?
- 2.4Ghz Routers only: Try single mode G or N or mixed G and N?
- Channel Width set for Auto 20/40Mhz or try 20Mhz only.
- Try setting a manual Channel (http://en.wikipedia.org/wiki/Wireless_channel) to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear.
- What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES (http://en.wikipedia.org/wiki/Advanced_Encryption_Standard), so you might want to try TPIK (http://en.wikipedia.org/wiki/Temporal_Key_Integrity_Protocol) only or Auto TPIK and AES.
- What wireless devices do you have connected?
- Any 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by?
- Any other WiFi routers in the area? Link> Use InSSIDer (http://www.metageek.net/) to find out. How many?
It recommended to download the FW file to your connected PC and send the file from there instead of having the modem update from the UI page.
If you do want to update FW, please follow this:

Point is: it worked perfectly during a month but later started drops out wifi so it is a Router problem not a software, I created a hotspot on my MAC and Wi-Fi works fine through it, but still not working through the router, just doesn't see it at all.

Tried everything you mentioned nothing helped, how can I send it to technical support for repair?

Just because it worked for a while doesn't mean that other WiFi routers could have moved in to the area and now maybe causing interferences...If it was working then something has probably cause the router to no work well now...
