Hi! Got me a WT-2 today. Installed it by the book and it connected ok. But the transfer-time is lousy. I have an Airport Extreme (54Mbit/s) and a powerbook 17" (54MBit/s). The WT-2 uses 54Mbit/s also and connnects to the camera with a USB2 connection.
My NEF-files takes about 20-30 sec to transfere. Both in FTP-mode and in Peer2peer mode (Nikon Capture 4.3.2)
WT-2 running in peer-to-peer mode (Ad hoc) will only support speed up to 11 MBits/s (IEEE 802.11b page 27 in user guide), which will allow a transfer rate of approx. a little more than 1 MB per second. A D2X NEF file will take around 20 seconds to transfer including verification in Capture.
In "Infrastructure mode" you should be able to get five times the transfer rate e.g. up to 5 MB per second. Try to check the transfer rate of your access point and see to that you also have a 100% signal from your D2X.
I did that too! Still around 20-30sec per NEF. I even set up a network just for the camera and the powerbook so there could'nt be any bandwidth loss from other apps and computers. 100% signal strength... And I have it set to "infrastructure" too...
Unless you're using something like a Sandisk Extreme III CF, you may find the card is the limiting factor, especially if you are shooting (and writing to the card) whilst transmitting. With my WT-1 on a D2H, I have to shoot slowly or just accept the fact that the images will take their time to transfer.
But it can't be THAT slow! It's useless in a real photo session then... I'll try the faster card to see if it's any different... I have the other scan disk cards, not the extreme kind. Don't know the name right now though...
Before spending money try shooting just one image with auto-FTP on and see what speed you get. If you connect at 54Meg and it shifts it quickly then unfortuneately you just have to slow down! The Sandisks below the Extreme III are Ultra II which I have - I've brought the 8Gb ones so I can keep shooting even if the FTP slows down (or I don't have my laptop with me). I can see a difference , even with the D2H file size, if I keep shooting whilst trying to FTP the files. It is a case of "what do you consider most important, transfer or shooting speed" and adapting to it.
I totaly agree with you there but there must me something wrong! I get about 5-6 Mbit/sec instead of (the unreachable) 54 Mbit/sec (calculated of 20MB sent in about 30 sec. 2/3 MB per sec = 5.6 MBit/sec) If I only could get like 20 MBit/sec I would love it. I get same speed regardless of using infrastructure or Ad Hoc.
The Ultra II CF card maxs out at 10 MB/s transfer. Extreme III does 20 Mb/s. These are from the Sandisk website. It doesn't say for the older CF (pre Ultra II) but they would be slower so you might want to see what your card specs. are on www.sandisk.com
I've heard a roumor that the intern Airport card isn't that good togeather with the WT-2 and that you should use a PCMCIA-WLAN card instead. I will try that out on monday at the resellers place... (YFO in sweden)
You'd think if you were set up to handle 54Mbps, it wouldn't matter what card you were using. Can you check your bandwidth in general to isolate the WT-2 as the issue? If you get 54 Mbps on your card using FTP or other applications, it would suggest that your card isn't at fault (necessarily). My experience with Apple wi-fi is that it usually works right the first time. However, I don't have a WT-2, so I can't say for sure.
What if you do this-- hook up your PowerBook to the Airport Base station physically via Ethernet. Then try to communicate via the base station with the WT-2. Then you can remove the card from the equation altogether.
