Upgrading firmware on Apple imac Netgear.

Hi i am used to upgrading firmware on a windows PC in the past for various firmware versions of a netgear router,pretty basic you download the zip file and then just upload it as a zip file into the correct upgrade section of the router.

However these firmware versions on a imac come down as a img file and when i upload and try and do a upgrade it does not work.

Am i missing something here and do i have to do something to the file to turn it into a zip file or whatever,do i need another extracting program or what as i am in the dark as to how to upgrade both my netgear routers using a Imac.

Mac is not my thing but......IMG files are similar to .ISO files and can be burnt to their correct disk format by most burning software

That sounds like a disk image file. Double-click on it and it should appear as a mounted disk. The firmware is probably on that disk.

From the Netgear site, it's a .IMG file, not zipped. You just d/load it your PC. Does not matter what type of PC it is; it is just stored there but not processed.

You then use the Web i/f of the router to do Maintenance => Router Upgrade and from there Browse to where you stored it on PC. It is then actually processed by the router's processor, not that of the PC.

You did obtain the firmware from the pukka Netware site? It will work from there on any PC.

To avoid any misunderstandings:

.img files are NOT disk images *. As stated above, in this case they are just compressed images of the Netgear operating software. You download the image file to your Mac, then install it onto the Netgear router using the router's web interface - typically at the url: http://192.168.0.1/. You can do this using Safari or Firefox or any other web browser you want to run on your Mac.

Log in as "admin". If you haven't changed the password (you should, you know!), it will still be the default one listed on the router's label.

Click "Upgrade Router" in the left hand column, and select the .img file you downloaded.

* .dmg files are disk images on a Mac.

Parrot!

I never implied they were! You must have the misunderstandings:

.img files are NOT disk images

That's news to me, and to Apple. .img files may not be disk images, but they also may be.* As the OP stated that he had tried uploading the image file to the router, and it did not work, I was suggesting alternative possibilities. It's not that difficult to at least test the possibility.

* It's true that disk images are often .dmg files, more often than .img, but that is not exclusive. Apple know best.

I guess Alan replied to the wrong post. But, in any case, he was completely wrong to state that .img files could not be disk images.

It's irrelevant! The .IMG files supplied by Netgear are solely intended to be processed by their routers via any PC.

I think you may be (unintentionally) confusing the issue...

"PC" implies what used to be known as a an "IBM-compatible" and doesn't include Macs. Any computer with an Ethernet port and a browser should be able to update the firmware on a router, from a hacked ZX81 to a Cray!!!
