So yea let me get into this right away. So basically I have a Wii U (the deluxe bundle) and have had it since a couple days after it was released back in November. I love my new system, but there is one thing that always seems to frustrate me. What frusturates me is that my Wii U can't seem to stay connected to the internet on my home's Wi-Fi connection (wireless connection). It's not that I can't get connected to the internet, it's that my Wii U will constantly connect and disconnect randomly at times. Sometimes it's every few seconds or mins, and sometimes the disconnection does not happen at all - it just seems random. For example sometimes when I open Miiverse, if I try to tap on the sidebar or go to a community I'll get a error code saying my Wii U cannot connect to the internet. Then if I click again (although sometimes it takes 3 or more tries) it will work. Another example is when I use different apps such as Nintendo TVii or the Eshop. Just like Miiverse, sometimes it works flawlessly, but sometimes I'll have to try opening them a few times before I can successfully continue without getting an error code message. Another thing to note is the blue box that surrounds your Mii on the home menu which signifies that you are connected will randomly turn orange and then back blue - showing that my Wii U trully cannot stay connected to the internet at all times. Sometimes downloading things take forever because of the constant disconnecting and reconnecting -- it literally took me almost 2 hours to download the Rayman Legends demo a few months back.
For refrence I managed to write down some of the few error codes I have gotten over time. I realize not all of them may pertain to my problem, but I'll list they ones I have written down just in case:
121-9999
121-9998 -- The first two happen to be the ones I've seen a lot
101-0704
102-2106
111-9000
102-2211
The modem that I use is a Bell 2Wire 2701 modem. Now before I go on I should also note that the Wi-Fi connection I have set up at home is reliable. Not only do my Wii, DS, DSLite, DSi, and 3DS consoles all work flawlessly on my wi-fi connection, but I also use my wi-fi connection for my house computer, my laptop, my iPhone, and as well as various other electronics that other members of my family happen to own. Of course only a few are ever connected all at once, but I have never had a single problem with my connection for anything else except my Wii U.
I also should add that I changed my connection on my Wii U to manually enter DNS settings. I did this when I first got frusturated with this problem as it what Nintendo seems to recommend for people having problems with their internet connection. I can say it seemed to work, as the disconnections happened less frequently afterwards, but they still happen nonetheless.
Just remember that this doesn't happen all the time. Sometimes I can use my Wii U flawlessly without any internet disconnections, but often times I will experience a disconnection at least one or two times when I play on my system. Anyways, any help or recommendations would gladly be appreciated.
