SGS2 on 5GHz wifi - Galaxy S II General

I recently got a new Airport Extreme Apple router [MD031LL/A] and wanted to know if the SGS2 can operate on the 5GHz WIFI frequency?
This router has both 2.4 and 5GHz frequencies.
thanks

Yep, mine can connect to my 5GHz wifi no problem.

Yes the SGS2 has a 5GHz Wi-Fi radio, and it worked for me with v2.3.3 of gingerbread, but since flashing any v2.3.4 it has not worked, though the 2.4GHz radio works in both versions.

Awesome!, but how do I set the sgs2 to pick up the 5ghz frequency?
It is turned ON on the airport extreme, but I don't see the SSID name associated with the 5ghz listed on the sgs2.
thanks

you shouldn't have to do anything, should just find it. I do find however the 5GHz band doesn't go through brick walls as well as 2.4GHz! so make sure your in the same room.

Based on your signature, you are using v2.3.4 of gingerbread, which like I said may not work.

Is there a solution to turn on support of 5GHz on SGS2?
Router works fine, notebook recieves 5GHz, sgs2 just don't see SSID. No difference between Auto mode and 5GHz.

As I said, no difference between variants on your screenshot, my sgs2 searches only for 2,4GHz networks. Looks like 5GHz option is locked on devices for some countries

thanks. Imma try this at work.
I am confused. Did you not know the stock froyo did wifi tethering? Am I not understanding completely?

You're not understanding completely. My desktop computer does not have a built in wi-fi adapter, so I would have to use a wireless USB network adapter to get internet on this machine. Using this method, I was able to use the internet from my ISP (Cox Communications) rather than resort to using T-mobile's 3G network.
Let me do a flowchart for you:

Yeah, okay I did understand.
The phone can tether the cellular signal or the wifi signal.
It was implemented in froyo.
What is really cool is how fast it is. My computer is hard wired into my home network and when I activate tethering and disable the wired connection, the difference in speed tests and pings is imperceptible. They are both the same. Very impressive.
I like what you've done. You are tethering your computer to your phone via USB and then using your phone's WiFi connection to connect to your home's WiFi router, then on to Cox and the Internet.
In your diagram, the Internet doesn't lie between your phone and the computer. The Internet lies beyond your ISP. Otherwise nice.
Lastly, the tethering features were added by 2.2 as pointed out already.
Edit: added a diagram

By default wifi is set to sleep when the screen is off. Have you disabled this in wifi advanced settings?
Took me a few minutes to understand...
The point to note is: "tethering shares whatever internet connection is available"
1) Connect to the wifi network using your nexus one.
2) Share the internet via USB tethering.

WiFi battery drain

I have terrible battery at home, but ok at work. Looking at my graph, the first 2 and last wifi line is home, the 3rd is at work. Mostly screen off. What's going on? Is there a router setting I can change?

I had bad battery life on my S4 right after release. I tracked it down to Multicast being ENABLED on one of my Access Points. I would recommend logging into your routers and/or) access points and look for anything related to Multicast and Disable it (or uncheck it).
Granted this was for a totally different device (note that my Nexus 7 was NOT affected by multicast) but it certainly cant hurt anything by disabling multicast..If it does, just enable it again.
My S4 was using approx 5%-8% of battery per hour with multicast enabled...once I disabled it, I now drain about 1% per hour.
This took me almost 2 weeks to discover...keeping in mind that my S4 never connected to the affected AP. I use that AP for older legacy devices.....just having it on the network affected my S4.
Give it a try..if it does not work..enable it again.
That does sound logical, and I've read about that in other threads. I have a WRT54G router and see nothing about multicast other than "filter multicast" under security (block LAN requests) which is checked to prevent multicast.
The other thing that has changed recently is I switched Cable modems from Cisco 2100 to Motorola SB6141. Not sure if I can change anything in it or if could cause problems.

I was running Tomato on the WRT54G and that is the setting I was referring to (but under tomato its in FIrewall - "Allow MultiCast"
It seems that you have the "correct" setting - To block multicast - As such, I'm sorry that my fix didnt work for you..
As far as the new Modem, it may be possible that multicast is enabled on the new one. Im not even sure if that is a setting you can change as those motorolas are locked down pretty tight by the ISP's

Your Note 3 WiFi max speed?

I get only 65Mbps link which disappoints me when router have 3 antennas and supports at least 300Mbps. Laptop easily connects at 270Mbps Link speed and I get 100Mbps download speed (limited by my internet provider). Any ways to get higher WiFi speed with Note 3? What is your link speed (you can check it in WiFi settings by clicking on network name)?
I get 433Mbps connected to my AC router.

What app are you guys using to transfer files to and from your Note 3 ?
I forgot this supports AC, maybe time to upgrade router!
Anyway, for now I'm using 5GHz band on my WNDR3700 and get a rate of 150Mbps which results in an internet speed of

Wireless N on 5GHz via RT-N56U, link speed is 150Mbps and speedtest got me 104Mbps. Mind you my internet connection is 110Mbps.

I figured out my problem. For unknown reason Note3 selected to connect to slower G network, not N. Solved by setting different names for G and N networks and connecting to N manually now I get 150Mbps link. My laptop somehow prefered N network if the name is same, but not Note3.
I must be getting the worse speeds ever approx 22 down and around 2 up. I have a 30 down speed line. Test conducted next to router. N9000 Cisco

[Q] 5Ghz wifi very unstable

Just got my N910G (AUS), and I found the wifi is VERY unstable when it is connected to 5Ghz band, but stable on 2.4Ghz.
Tried it on 2 different modems/routers, same.
Never had any problem with my other phones connecting to 5Ghz (M7, Z2).
Any idea?
The phone is stock, non-rooted.

I'm not saying I get poor speed, I'm saying my connection is unstable (lots of disconnections).
Speed is fine.
Factory reset or try latest update/ odin flash latest fw.
You might also fiddle around with which channel your router is set to for the 5ghz band. Turn off the smart network switching too.

Factory reset is not a solution to every little problem. In fact, it's not a solution at all. If you don't find out what's wrong, you could hard reset your phone, set it up from scratch and still be faced with the same issue.

Agree :good:
1. Go to dial keypad and press *#0011#
2. Press menu key and press WiFi option
3. Turn Wifi Power Save Mode off

Just change the 5ghz wifi channel to that which is obviously suitable for all your devices. Also had this issue but my PC was able to connect to both 5ghz channel on my 2 dual band routers while the phablet won't. I fiddled and discovered the lower channels worked perfectly

Droid Turbo 2 WiFi problems

Is anyone having an issue where WiFi disconnects on its own and seems to disconnect the phone from Verizon's network as well.

I haven't had that problem. I only had a problem with the advanced calling feature turned on during a call.
I did where the phone showed still connected but router showed disconnected. It is not a phone issue, it was an issue with my Linksys N router

What was the issue with the router causing this? Did you fix it?
Thanks!
It seems to be a problem on both the Turbo and the Moto x pure, many people in the Motorola forums say they purchased a new router and it seemed to work. I personally won't be buying a new router just for this phone. Hopefully it will be fixed with the marshmallow update
Well I disconnected my Linksys Router and used the Comcast modem and setup WiFi with it and works great now
extremely frustrated with turbo 2 wifi
I'm having the same problem, and it's true on at least 3 different routers so far. I surely won't be replacing every router I ever need to connect to. As a frequent international traveler this is a HUGE problem for me and will result in my getting a different phone before my next international trip if it is not resolved quickly.
Are they all linksys

No. Haven't tested on any Linksys. All were Netgear routers, 2 with N (running DDWRT) and one with AC (factory firmware) protocol.
Don't know then. Mine has worked fine on a netgear R7000 on stock and dd-wrt.

Question: Are others who are having this problem on open networks because I share am open network with other people who live at my residence and I don't have this problem when I am visiting my friend who has a secured WiFi connection.
