This has nothing to do with different devices. I have the same problem with my note 2. But i think its happening when the device is in deep sleep and then gets connected to a wifi router. The ping is rising to about 200 ms and the download speed gets aroun 500 kb instead of 30 mb. After disable wifi and re enable the speeds are normal again. I also experienced this with note 10.1 and s3 and htc one x. I think its a huge bug in android. Also my xoom tablet has the same problem. I tread netgear cisco and tplink routers. All with the same result. It must be 4.x android causing this

I could use it and restart it and it will still do it. Once in s while itll get s bug up its charging port and work fine for a minute and then crap out to slow again. I used my other devices as a reference. I think there might be a conflicting app that could be causing it. It doesn't matter what signal or router it wont change.

Yeah, my wifi speeds are horrible. I have 30mb Internet with a Motorola Surfboard 6580.

I was having the same issue. I found this link:
How to Fix Galaxy Note 2 WiFi Problems in 5 Seconds

I rebooted my phone, turned WIFI on my phone off then back on, then in my options I set 'Keep Wi-Fi on during sleep' to always. My download speed jumped from less than 3 Mbps to over 20 Mbps, and is working great now!

changing advanced wifi to always on fixed it for me

Funny,, I have never had any issues with my wifi. After reading what you are doing to fix yours I went to check what my settings was on and it is indeed set to "always". First time I have ever gone into them settings.

IT'S TRUE,, SIZE IS EVERYTHING!

I have a samsung note 10.1 and it starts downloading fast then slows down over time. If I restart the tab it speeds up and again slows down over time. I can download the same file with my computer or phone and there's no slow down

I am too having slow wifi problems I have the note 2 and my husband has the Galaxy 3. I just looked and we have our set up as G. Still slow as hell..How can I fix.. I got a Linksys router..

[Matt Behnken]

I found the solution. The 5ghz broadcast was causing interference. I disabled the 5ghz broadcast on my router and only have 2.4ghz enabled. No reboots and speed test went from .56 Mbps on multiple servers to 30Mbps on the note 2! Hooray

Edit: I already had ALWAYS keep wifi on when sleeping and still had the problem until I disabled 5ghz in router settings on my Cisco linksys E2500
