Question: Does WU-1a work with Nikon D90
Document: After noticing that it didnt it my camera. I sent an email to Nikon and they answered my question by saying that this product WU-1a or the WU-1b did not work on the d3100. I will be returning the item. :(
For the what I was going to use the WU-1a for, didn't work well. I wanted to set my Nikon D7100 up remotely, and use my iphone to take pictures of wildlife. The problem is the delay. If the subject moves any, you won't get the shot you want.
iOS version for this adapter has just been released.[... ]Hopefully the links work but if it doesn't just do a search (Google Play or iTunes) for:  nikon wireless mobile adapter utilityThis is for your supported Nikon DSLR (D3200 for me) and the WU-1a or WU-1b adapter. This allows you to take pictures wirelessly from your iPhone/Android device. I have used this on the iPhone 4 and the Samsung Galaxy Nexus.Works as advertised for me.
I can take pics with my Nikon D3200, plug in the WU-1a Adapter and instantly send them to my iPhone no matter where I am. I didn't expect it to work so easy. I just used it the other day on the soccer field (no WIFI) and was able to send the pics to family. For some reason I thought I'd have to be on a WIFI network for it to work, this is not the case. I'm so glad I bought this and would highly recommend it.
It came as part of the Camera kit for a D7100 and I really looked forward to setting it up. Unfortunately, it doesn't work with ANY of my 5 Android devices. I don't know if anyone is working on updating the app to include more devices but I'm not going to wait and will purchase the CamRanger. Anyone want to buy a new WU-1a cheap?
The WU-1a Wireless Mobile Adapter would NOT connect to my Nikon D7100. Nothing I tried worked. Download and installation of app to my Samsung Galaxy 3 was fine, but module did not function. Returned to Amazon.
I hope Nikon fixes this, what promise it could have! With my Galaxy SIII 6&#34; from the WU-1a it won't stay connected for more than one picture and then takes me 10 minutes of setting and resetting over and over until it wants to connect again. The software for taking a picture is an extension of &#34;live view&#34; and all its disadvantages.
I was very hesitant to buy the Nikon 3200 because many reviews I read said the Nikon Iphone app had issues. Well I bit the bullet and bought it for Christmas along with the WU-1a wireless Mobile adapter. It took 5 minutes to set up and it works as advertised. Love it. So Glad I bought this over the Canon EOS
I'm a gadget lover, so naturally I wanted to find a way to connect my iPhone to my camera. This appears to be the only option for our Nikon D3300 so I paid the $60 to try it out. I've been forcing myself to try and love this thing ever since, but it's just not that great.Ours will disconnect often between an iPhone 5S and D3300. Even when I turn on Airplane mode and only connect to the WU-1a.
Additionally, every time I activate the mobile app, it&#8217;s in German. No matter how many times I set the language to English, it always loads in German. And as so many other people have complained, the mobile app icon stays permanently in the phones notification bar.The WU-1a wireless mobile adapter is a great idea; it&#8217;s a shame that a company like Nikon can&#8217;t make one that works.
Answer: No.  Only the D3200 for now.  It doesn't look like the D90 has a wireless adapter.  Seems to be only available on the newer cameras.Click the "Compatible With" at the link below:http://www.nikonusa.com/en/Nikon-Products/Product/Wireless/27081/WU-1a-Wireless-Mobile-Adapter.html?cid=prt-0512-wu1a
