defender offline cannot update no internet connection

HI,
I read the posts, and could not find an answer for this. ... so I am posting it here.
I downloaded the defender offline 64 bit on a usb drive.  I run windows 7 64bit.  When I tried to boot from the drive, it says the definitions are outdated, however when I try to updated it tells me that there is no internet connection. I do have internet connection of course. I also tried to plug in the laptop rather than use wifi. No difference. Why doesn't it recognize my internet connection? Is there another way to update the program? Thank you.. this is puzzling truly.  
PS
I don't have any problems with my computer, but I wanted to see how this defender worked just in case I will in the future. prevention.  Oh I have AVG free antivirus. thanks

The good news is that you were only checking it out. The bad news is that you have encountered two problems with WDO that are common.

1. When you created the USB boot media from the WDO download it installed the latest definitions. WDO doesn't need to update when you boot the laptop from it. However, in some scenarios that I still don't fully understand (one is a multi-boot system where more than one OS is installed) WDO doesn't look on the WDO meda which should be %system% for all intents and purposes, but looks on your hard drive, and thinks it needs the definitions. This is, in my opinion, a defect.

2. Support for updating WDO over a wireless network is pretty much non-existent. I am not aware of any supported WiFi adapters. Updating over the hard wired network connection will only work with a limited number of network cards and there is no published list of supported NICs.

So, unfortunately, you won't be able to use this version of WDO. Perhaps in the future these limitations/defects will be addressed.

In the meantime, there are alternative rescue scanners you can use:

Each rescue scanner will miss things – because none of them will have a perfectly complete and up-to-date set of definitions; so you might need to use several of these rescue scanners, or something like the Shardana Antivirus Rescue Disk Utility, which creates a custom bootable CD or flash drive that includes multiple rescue scanners:
