In case anyone else is having WiFi performance problems (I know I was) I found a setting which seems to have helped.
Go to Settings...Wireless & Networks...Wi-Fi settings. Turn-off WiFi for now. Then hit the Menu button on the bottom and choose Advanced. In that menu check "Best Wi-Fi Performance". Then turn Wifi back on.
I am also trying WPA/WPA2 PSK with TKIP encryption instead of AES.
For me with WPA/WPA2 PSK with AES and the default setting of "Best Wi-Fi Performance" disabled I was getting poor results (with a NetGear N600 WNDR3700 router). I was testing with TKIP instead of AES when I stumbled on the new-to-me WiFi performance setting so I don't know which one helped but it works now and I don't really have a TKIP/AES preference so I'm not messing with it.
Since it helped me I thought I'd share.
You may not want to use TKIP. If you check your network, it will not be running at wireless N speeds. Draft N specification does not allow use of TKIP. Plus it's generally a less secure encryption algorithm. Thanks for the wifi performance tip btw!
OK. I set it back to AES. Seems like it was the enabling of
Settings...Wireless & Networks...Wi-Fi settings...Menu button...Advanced...Best Wi-Fi Performance
was what made the difference. When I uncheck it the performance goes back to bad.
Anyone know what that setting does?
Good question. I'd assume that is simply diverts 100% power to the WiFi transmitter. Anyone ?
It increases power to the radio, yes, to increase the range and speed. Supposedly smooths out shaky/faraway connections.
In your house, you could probably get a similar boost by tweaking your router, without the battery drain.

Can you elaborate on what one can do to tweak the router settings. I'd be willing to test and report back.

I'm getting often wi-fi drop outs throughout the day and the only way to fix it is by restarting the router?!
Restarting the phone doesn't work
Turning off/on the wi-fi doesn't work
Switching bands doesn't work
yet it still allows connection to BTFON/BT OPENZONE? But won't connect to my broadband.
It's kind of annoying, because on the status bar it shows that it's still on wifi but going into settings and turning it off/on then shows it's not working. As it won't connect to the internet obviously.
Anybody else getting this? Any fixes?!
Thanks.
I have an issue where it just briefly drops the connection and reconneca, sometimes it is connected but can't access internet unless I cycle wifi.
I am on the Optus, Australia S3.
I have tried it on both my access points, it can't sustain a Skype call-keeps choking up-I am hoping a new kernel or custom ROM may help-tried Omega, but had barely any phone signal.
I have sleep set to never, have tried 2.4GHz only....a bit annoying, but Ireckon it should be sorted soon. It is the only issue I have.

Try changing the security type of your router. It's often better to pub less encrypted seucurity. For instance try removing security completely for a few min and see if the problem carrys one. Then it means the problem is from the security of your router and then change the type of security to something different than it was before and should fix it. good luck

Hmmm i just changed it from WPA2 only too WPA & WPA2.. seems to be working at the moment.
I'll report back later.
Is it a bug that it doesn't support WPA2 or something?

My S3 has no problems with my O2 wireless access point (provided by BeThere), but I'm using WPA/WPA2 rather than WPA2
You are in UK as well, are you on Orange and using the "Your Wifi" app to manage the access to free BT hotspots?
No wifi issue get it exchanged.

Oh No it's not a bug! Some times different routers are not well at making a steady connections with certain devices through high encryptions. As you remarked the problem is not an issue incase of connecting to BTOpenzone and yes pretty much. This problem can often be solved without the need of even purchasing a new router. Simply head over to your router's setting page (should be something like 192.168.xxxxxx) then see if it's possible to upgrade your router's firmware.
See this link, maybe it will give you an idea of what I'm taking about

I'm assuming you're using a bt homehub of some sort?
I'm using a bt homehub 3 and I've been getting constant drop outs when downloading files over wifi.
I tried a lot of different fixes and was clsoe to throwing the phone out of the window lol
What seems to have solved the drop outs for me is using wpa instead of wpa2.
Try a factory reset?
I'm also on a BT Homehub and i haven't had a single problem, i did a factory reset as soon as i got the phone to prevent any issues.
Anyone know of an app that will boost my wifi speed at work over others?
Server speed is good just so many other devices and pcs it makes mine very slow. Its very frustrating 
Thanks in advance

you can configure this on your wifi router. if your wifi ap is basic one it might not have this settings. but most routers come with option to set high priority, qos etc.
Im at work tho mate.. im sure this can be done with just my phone

Cannot see how a receiver can receive priority over others without it being set at source .
jje
The whole point of Traffic shaping would be lost if any device can set itself to a higher priority.
Some packets can set an URG-flag which stands for least-latency routing instead of least-cost routing however it's still the router's call if he respects this and if yes how he treats them.
Something else is probably incorrectly configured. It's been reported several times that the S3 is very picky when several Wifi AP's with the same name (SSID) and in reach of each other are configured on the same channel (frequency). However most hobby-admins even know not to do that, so if your company is doing it you might suggest basic network training for your IT guys. (The basics of the Wifi protocol are in roughly the 3. semester at university)
You might want to try whether forcing the device to 5Ghz band will make it better since that band is far less crowded.
Also you could check WHAT causes the issues. Often it's not the bandwith by itself but either the router's connection table (a VPN to an external server is a very good but cumbersome solution) or the DHCP (use OpenDNS or Google DNS)

Because, according to your latest signature, you're on ParanoidAndroid which is not Sammy-based.
This information was lacking in your prior post.
Im using omega.. is this only possible on samsung based roms? Would it make much difference in me doing it? Id be happy to flash a sammy rom if it can get me a better connection at work. It takes around 10 mins just to post on here when im at work. And thats only after turning wifi off and on. I get good signal at work, and the speed tests are good. Hmmm

Since this problem has not been resolved on other threads where it has been asked, i'll start a new thread for this
I have a Rogers (GSM) EVO 3D.. Got it last month.. On stock RUU and as well as Yoda's ICS ROM (Yoda's Kernel), the wifi automatically keeps turning off and on when its enabled.. tried flashing Stock RUU again but that also is unable to solve this problem..
Can this be a Hardware issue?? any insights plz..
It's definitely not a solution to your problem, but you might try installing Wifi Analyzer which is free from the Play Store to gather more information. WiFi drops can sometimes be attributed to channel conflicts between multiple access points, and that tool will help you see how strong your signal is and what might be interfering.

ramjet73.. thanks a ton.. interesting observation.. my wifi router is placed hardly meters from my desk with almost no blockage is between. normally the signal strength is -85dBM. but when wifi analyzer is switched on it increases to -65dBM(goes down once its closed..
Its currently on Channel 6 and all the channels are with full star ratings.
Only devices attached to my router is a wired desktop, and on wifi a laptop and 2 android phones.
The problem has not occurred while wifi analyzer was switched on.
Will update after further observation.
another option could be to go into you settings and while in the wifi section, hit menu and and go to advanced and check the box for best wireless etc...
That might help as well.

Did That.. After this and ramjet73 work around.. noticed that the drop is happening only when its in sleep mode. wifi always awake is ON.. but stil its better then before.. will flash a new hboot, kernel and rom and see if that works..
ps - i have stopped using wifi for a day and i mostly keep phone on 2G (main use is whatapp and gmail) the battery life doubled
My Internet speed is roughly 50 down and 5 up. I use a Netgear modem/router (this was the router that worked correctly with all of my demands). I have an iMac that will get the full 50 download speed via wifi. My iPad gets around 30 (not the full 50 but satisfactory)... but my Note 3 is around 1Mbps. Maybe sometimes it'll spike up in speed for a few moments... But it's so inconsistent. I tried using different channels on the router.... No improvement. (the upload speed is fine though. It'll usually be the full 5mbps)
Any ideas on what's going on? Any settings on the router I can try to help improve this? (stock note 3).
Any help is appreciated. Thanks

Digital Trends has an article that has some tips on this issue:
Glitch: Wi-Fi issues
Some Note 3 owners are having trouble connecting to Wi-Fi networks, finding that the Wi-Fi is very slow, or that the device keeps dropping the connection. There are a ton of potential reasons for this and consequently there are a ton of potential fixes. Here’s what you can try:
Workaround:
Some people with stability issues have been able to get solid Wi-Fi connections simply by making sure that mobile data is switched off. Just drag down the notification shade and toggle Mobile data off.
Potential solutions:
Go to Settings > Wi-Fi and tap Menu > Advanced and then uncheck Auto network switch. That seems to have helped some people.
Try turning off the Note 3 and your router for a few minutes and then turn them both back on again.
Go to Settings > Wi-Fi and long press on the problem connection, then tell the device to forget it and set the connection up again from scratch.
Try out the free Wi-fi Analyzer app and see if crowded channels could be the issue. If so then change the channel on your router.
Make sure that your router firmware is up to date and check settings like MAC filtering.
If you’re having stability issues then you might try disabling the apps Wi-Fi Direct and Wi-Fi Direct Share via Settings > Applications manager on the All tab.

Thank you for the reply. Unfortunately nothing seemed to of helped.
I do not know how to tell which type of router I have. I can tell you it took many routers to find the right one (NetGear C3700). I went through a bunch of Time Warner crap and several from Best Buy......even Motorola's flagship modem/router. It needed to do the following:
Provide open NAT type for Xbox live
Allow my Android device to recognize the Xbox One as a device on my network (pics, vids & music through the console)
Allow Android Youtube app to communicate with the Xbox One Youtube app.
Allow proper connection to my iMac via Wifi (One of Time Warner routers would not work with my iMac)
My BT and Wifi havent worked the same since the KitKat update - Thanks again

Man that sucks, I had serious issues with 4.3. since KK I've been rocks solid with WiFi,
You might try to old factory reset (which sucks I know) just backup first so if there is no change you can restore easy enough.
What ROM are you running? Stock?
Set your wireless channel away from everyone elses. There is a setting where you can just set it to just 802.11N save it. Try setting your wifi port to static for your device. Check your wifi settings on your device. Make sure your using the same channel on your device as for the router.

I've already tried a factory reset since the KK update (for Bluetooth issues). No help.
The phone is stock.
I've tried changing around the channels a little bit with no success so far. How can I change the channel on the device? How do I set the port to static for my device?
Thanks
So I've seen a few posts about slow wifi on the G5 here on XDA but can't remember there was any solutions really.
Has there been any progress regarding to this?
Seems like my wifi suddenly drops from time to time (like every 2-3min or something), the "wifi bar" doesn't drop for even a second though so I guess it stays connected but isn't able to pull/send requests.
Getting quite annoyed with this since it's faster with my 4G network on than 100mbit wifi.
Also, might be a coincidence but overall I feel like my wifi got slower when I got the G5, on my Macbooks etc that is. Could of course be some router issues but not likely.
Any ideas? Kinda bummed out since I love the phone.
Might be a ip6 issue it is on my g4 use an app called disable ipv6 and it helps. Dont know if g5 suffers from the incompatability either
I would replace the phone. I get no wifi drop out and wifi is blazing fast when my internet connection at work and home isn't playing up.
If you can, disable IPv6 on your router, or if you have the European Varient and have root, there is a script to disable it on your device. I had the same issue and that was the trick. Get an app to test for an ipv6 leak before-hand, just to be sure.

ALSO, If you head into your developer settings, you can enable "Legacy DCHP" I have found this useful on a number of devices that were having issues with WiFi.
