I have a SamSung Galaxy S 3 running Android 4.1.1
My Router is a Netgear Dualband WNDR3400

I have been having problems with my wifi connection going in and out constantly on my phone.

First thing I want to mention is that I have 3 PCs, a 360, and several Apple Devices connected alongside my Galaxy S3. My Galaxy S3 is the only device that gives me problems.

I have tried a solution posted here---> http://androidforums.com/samsung-galaxy-s3/566171-wifi-issues-disconnects-etc-fixed-me.html

Unfortunately this changes nothing as I can literally watch the connection go in and out on the debug menu and on the notification bar up top. The only constant is the IP Address which I have verified with the rest of my devices whether it is causing conflicts or not and it is NOT.

I have disabled the option to turn wifi off during sleep as well. I have reset the connection at the phone's end(deleted the network and readded it).

The solution I found was posted here --> http://androidforums.com/samsung-ga...-s3-wifi-connection-problems.html#post5135368

This is the latest solution I have found to this problem and before I go and do this I would like confirmation from the community that it works.

My alternative solution, which I would need confirm also, is an upgrade. In Octoberish I am due for an upgrade and am looking at the Galaxy S4. However before I invest in such product one of the most important points would be is this problem still present in the Galaxy S4?

 

Actually to be honest I think I am broadcasting both. I could have sworn I disabled the 5 ghz a couple of months back. Not everyday I am fussing with the router's GUI .

How would I be able to ensure that only one of the bands is broadcasting?

I dont know if the GUI is the same for all Netgears but mine is similar to this ---> https://www.google.com/url?sa=i&rct...x6KXlDZFOngLOfZ681sf7cfQ&ust=1372609922284727

 

Just checked my settings. 5ghz is actually turned off. only the 2.4 band is currently broadcasting. Now I noticed that inside the regular Wireless Settings(as opposed to Advanced where I was able to turn the radios on/off) I can broadcast on different channels. Could this have some kind of effect as well? Would I have to reconnect all my devices from scratch?

Currently the channel for the 2.4 ghz is set to auto.

Also before I forget, my room sits right on top of where the router is.
