[SUMMARY]
For optimum speed when downloading to Wii U:
- Use an external USB HDD/memory stick
- Use a Wii LAN adapter not WiFi
- Use a local proxy server to help keep a sustained download speed
Downloading to the internal memory is bad, it averages around 400KB/s. With the changes above I can get 2.5MB/s which is still not perfect (my connection can do 10MB/s) but much improved.
[WII U UPDATE 3.0]
Dramatic improvement in performance!
I was able to get an average of 2.5MB/s from the USB adapter downloading to a HDD with the proxy enabled. Without the proxy it fluctuates wildly but still seems much faster than before, I suspect it may average around the same but its harder to measure when it fluctuates so much. Either way its a big improvement.
Downloading to internal memory still is garbage at an average of about 400KB/s, it did peak a few times at 1MB/s but then seemed to stall for a second or two (while it saved the data to the storage no doubt). As previously suspected it seems the internal storage has very slow write speeds which is bottle-necking the download. Its annoying as if I had known the built-in memory would be this bad I might not have bought the Wii U Deluxe. This is particularly relevant as saving to a cheap USB memory stick performs almost as good as an external HDD, doing between 1-2MB/s even while playing LEGO City Undercover at the same time which is excellent compared to PS3/Xbox 360 which slow down to 500KB/s when background downloading.
One of the big problems with the Wii U is that the downloads seem to be split into many different smaller files which slows down things a lot as the nature of TCP/IP is you start off slow with each connection and gradually speed up as it detects you are capable of handling it. So its far better to download one big file rather than several smaller ones.
The new background installing seems to be a huge problem too now as when its stalling the Wii U becomes unresponsive when trying to move between sections of the UI. I just tried to view Download Management and its just sat there on the loading screen for about a minute. The same thing happened when I tried to go into settings earlier, I had to wait several minutes for any response at all, the home menu just locked up.
There is one good thing though, background downloading/installing doesn't seem to affect actual retail disc playback at all. Clearly the issue is downloading to the internal storage while also trying to read the OS from internal storage, is a bad idea. I While in a disc based game you aren't really doing anything with internal storage (except when saving the game) so things work smoothly.
Netflix still doesn't seem to work very well for me though, PS3 continues to remain the most reliable device to playback Netflix in top quality.
[ORIGINAL POST}
I just encountered a strange Wii U networking issue.
I was trying to watch something on Netflix yesterday and noticed it was stuck on Medium SD quality after previously being on Medium HD quality. So I finally decided to order a Wii LAN adapter to see if it would help. It arrived today and its the strangest thing, as now Netflix is stuck on Low SD quality. So I decided to do a test.
I deleted the FIFA demo and set about re-downloading it.
First I tried the LAN adapter and was astonished to see it averaging 50K/s. After swapping between WiFi and Wired a few times it managed to sustain around 300K/s.
Now here is the odd part, WiFi does between 500K to 800K/s.
Neither is particularly good seeing as on the best client (my laptop) my WiFi can easily max out my 65Mbit broadband and even get 80-110Mbit from the LAN. I get at LEAST 30Mbit on my phone, often twice that.
So what exactly is going on here? It makes no sense for the LAN adapter to function slower than WiFi. At worst they should perform identical, if the slowdown is happening on the Internet itself or the Wii U networking stack.
Now for the record, this IS an unofficial adapter, but by its nature it HAS to be using the same chipset as the official adapter or it wouldn't work at all. I suppose it could be using a slightly different revision of the chipset that has compatibility issues with the Wii U driver, but it seems unlikely.
I must also note that I tested the LAN adapter on Windows 8 and got 100Mbit down, 81Mbit up, so its clearly not faulty.
Has anyone used the official Wii adapter and gotten better results?
