[Q] 5 Ghz WiFi enabled device?

[fenrasa]

Hello,

as I've read on the net, i9100 should be a dualband wifi device. 2.4 Ghz AND 5 Ghz ought to be supported.

I that true? Is someone actually using 5 Ghz-only mode or was that just marketing buzz?

No, it doesn´t connect to 5GHz WLAN

 

[Yarymo]

How could I control it ? I don't have anything related to it in my settings' panel ^^'

No, it doesn´t connect to 5GHz WLAN

it does, i´m using it once in a while

You are right! I just tried that, and it works just fine.

 

[fenrasa]

Thanks for your answers. But which one is correct?

Did you set your Wifi-AP to IEEE 802.11a which is 5Ghz or to 802.11n, which uses 2.4 AND 5 Ghz?
Please some more details. Right now the possibility for dualband is still just 66%

greetings

My case :

My house Router Setting - 2.4ghz band for Wireless G and 5ghz band for Wireless N... Both worked with my phone. But G on 2.4ghz more stable (most of the time 3bar or more), fot N on 5ghz sometime no network coverage.

My router : DLink Quadband DIR825

Sent from my GT-I9100 using XDA App

I'm using Apple's Time Capsule with both 5 Ghz N and 2.4 Ghz G and N.
As usual 5Ghz is faster but weaker in signal strength.

I tried to set my router to 5GHz mode, and it wouldn´t find the WLAN even if I´m standing next to the Router.

I only tried 802.11n, not 802.11a.

But as others said differently I may give it another try. My Firmware is still KE2, maybe the updated the WLAN-driver later?

I´d actually would like to be able to use 5GHz, as there are quite a few 2,4GHz WLANs next to me, so bandwidth isn´t always the best.

 

[fenrasa]

So, whats the case now? Are there several different Hardware/Softwarelayouts on the market or why are there these differences?
Can someone confirm that pure 5GHz wifi works or not, based on trial and error, and post his Firmware-details?

Greetings,
Fenrasa

EDIT:
i googled something VERY interesting:
[Firmware] I9100XXKG1 (Android 2.3.4) (05.07.2011) is supposed to be able to connect to 5GHz Wifis. Can someone try it out and confirm it?
Another poster to the thread wrote, that "KE2 and 7" ought to connect to 5GHz wifi as well.

No people some ROM's supporting some NOT !!
Example: Stock Rom -supporting!
and LeoMar75 Rom Revolution

My EU device with KE7 ROM does connect to 5GHz on my WNDR3700 router. IIRC I had to make the SSID visible to make the original connection; once the connection was set up, I then reset the SSID to hidden.

 

[fenrasa]

Allright!

Samsung Galaxy S2 i9100 on I9100XXKE7 logged into my 5GHz Wifi. (Buildnummer GINGERBREAD.XWKE7)

Thank you all for your help!

Just a follow up question to this:

It appears the GS2 does have 5ghz support at least to some degree.

Is this 802.11a 5ghz, or 802.11n 5ghz, or both? And on a side-note, what's the fastest speed you've got it to negotiate with wifi? On my Galaxy S, even with 802.11n and 10 feet away from my router, I usually max out at 72 mbps.

 

[3waygeek]

It definitely supports 802.11n at 5 GHz, as that's how I connect to my home network. I have no idea how fast the link is -- never bothered to check.

Now that I'm at home, I just connected to my 5 GHz 802.11n, and the link speed reported by the SGS2 is 65 Mbps, the same speed I get connecting at 2.4 GHz. I'm sitting about 2 meters from my access point, and the 5 GHz signal strength is only "good", as opposed to "excellent" for the 2.4 GHz.

Interesting, thanks 3waygeek! Glad to hear 5Ghz appears to work with 802.11n.

*Bump*

Anyone else have any experience/input?

5ghz works here too, speeds seem to be faster( not that they matter on real life conditions) but signal ill always be weaker for 5ghz as it doesn't penetrate walls and such as well as 2.4

I am quite confused about the statements here regarding the signal ranges of a....n..
can somebody have a look at "http://en.wikipedia.org/wiki/IEEE_802.11" they give the largest ranges for ...n signals. The only thing I can confirm is that yes, I can connect to all: a... and ...n..

Well it may be useful to gather a collection of working/not working stats together to find the best rom/kernel/modem combos.

NOT working (5GHz network not detected, Time Capsule with separate named 5GHz channel, picked up fine by Macbook Pro):

ROM: VillainROM 2.4.2
Kernel: 2.6.35.11 ninphetamine 2.0.5, and also 2.1.3
Modem: XXKG6

ROM: LeoMar75 2.6 - XXKH3
Kernel: 2.6.35.11 ninphetamine 2.1.3
Modem: XXKH3

 

[lumingzuiku]

well, for those who can't connect to 5Ghz band, try to adjust channel setting on your router may solve the problem.
My S2 only supports 36-48 channels currently, and I can't find any region option in the setting menu.
BTW, yes, the 5Ghz signaling strength is not as good as 2.4Ghz. However, the trasmission rate (or efficiency) is much better than 2.4Ghz due to less interfere.
