Topic: Do your Wii U disconnect from your Wi-Fi often?

Use this, 90% it works (worked perfectly on mine, went from not working at all to flawless)
1. Go into connection types, Hit "Manual Configuration"

2. Input your SSID

3. Input the correct security type, this is key.

4. Put your password in properly

5. For ip address "Do not auto obtain".

6. open up cmd in your computer, type in ipconfig

7. Now input that ip address but add 10 to the last number so "192.168.0.1" will be entered as "192.168.0.11"

8. Enter the rest of your info inside such as subnet mask and default gateway exactly as you see it in your ipconfig.

9. Now hit next, hit configure now for your DNS. When asked about DNS hit "Dont auto obtain".

10. For the first server put in 8.8.8.8

11. For the second server put in 8.8.4.4

12. Hit Next, when asked about a proxy hit no proxy

13. Leave mtu as the default

14. it should work, if not check the ip and that it is the internet ip + 10. Good luck

I had to do that when I was setting it up,it would not connect for me.Now though I am having some problems downloading from Eshop.Some downloads get an error and say data is corrupt and I need to delete.This had only happened with several demos so I wasn't too bothered but now it's happened with Resi Evil I bough yesterday.It gets to 99% and stops saying its corrupted and I need to delete.Tried 3 times now.Done some searching online and some guy said to do something similar to what you just wrote but with slightly different numbers.Problem is it didn't work

Different numbers probably wont work. IP changes from one internet to another.

I make sure that my wireless router is up to date, whether that be by firmware or hardware, so that I don't have to do any of this.

I have the newest AirPort Extreme - never had issues connecting with the old one either, but I guess the DHCP in all wifi routers isn't that great. I gave my old AirPort Extreme to my partner and switched off wifi on her BT Hub and her network connectivity is a lot more stable.

Fixed IP seems like a good solution to that issue, good suggestion. Just FYI their are three IP ranges that exist for internal use depending on the size of your home network: 192.168.0.0-192.168.255.255, 172.16.0.0-172.31.255.255 and 10.0.0.0-10.255.255.255. Most routers are configured to use either the 192.168-net or 10-net in my experience.

Re: DNS I find OpenDNS very reliable and free and offers some nice filtering options for parents. I find a lot of ISPs can't be bothered keeping their DNS servers well-maintained so again, good suggestion on defining them yourself, though I don't recognise the addresses you're suggesting.

or just buy a USB to Ethernet adapter. download speeds and online stability has never been better

My Wii U never disconnects from my router.

I have never had issues.

I can vouch for this method. I used it when I first got my Wii U at launch. Only back then the information wasn't as plentiful as it is now. It took me many hours of Google searching to figure that out.

On the subject of fixed IP an alternative is to set up a DHCP reservation on your wifi router. When the Wii U is connected note down the IP address assigned and then get the MAC address off the Wii U and assign that IP to the MAC address, that way the Wii U will always be assigned that IP when it joins the network. Obviously the method will depend on your router make-model, but the Wii U MAC (Ethernet or hardware address) can be found in the network settings.
