hi. can anyone confirm the wifi spec of the gt-i9100. the samsung site states :
802.11 a / g / b / gn (2.4GHz / 5GHz)
but i believe there are other things that have to be taken into consideration. i have a netgear wn802t-200 access point which is an 802.11n 2.0 device supporting single band 2.4ghz and dual channel 20mhz & 40mhz, which in theory is up to 300mbps. my sgs2 will only connect at 65mbps which suggests to me that it only has one antenna and only supports the 20mhz channel. is this correct or should i be able to get a higher link speed with this access point ? i can't find this definitively answered anywhere so am hoping the good folks here can confirm. cheers.

We don't seem to have a Q and A section yet for the SII. Just ordered mine but still finding out more about it. The Samsung website mentions it has dual channel wifi and that means it is much faster. Sorry but what is dual channel wifi? Can't seem to find a simple explanation. Do you need to have a particular router or anything else to benefit from it?
TIA

you don't need a particular router... it just means it has a wi-fi antenna for the 2.4 ghz band and the 5 ghz band... this means the phone should support wireless A/B/G/N(2.4ghz)/N(5ghz).
While a dual band router would give you all of these options you don't need it....
Summary:
Dual Band WiFi in phone = Able to access any type of WiFi hotspot
I own a dual band router and I was glad when I read a few weeks back that it had indeed dual band wifi, just like my Galaxy Tab. HTC phones don't have it, so it's an advantage in comparison with the HTC Sensation.
Usually the 5GHz band is faster, probably because it's not as common and thus not as crowded as the 2.4GHz band...
it is faster but not necessarily for the reason of less devices using it... honestly when it comes down to it it's band width... higher frequency typically = greater bandwidth
Does It support 5.0Ghz frequency band?
I would would really like to know thanks in advance
Sent from my Samsung GNexus <3
Yes, the XPS has a BCM4330 chip which supports 802.11a/b/g/n.
http://www.broadcom.com/products/Wireless-LAN/802.11-Wireless-LAN-Solutions/BCM4330
How come my XPS will only connect at 65mbps to any wireless n router?
My dlink supports 300mbps and my laptop will connect at 300Mbps but not my phone
Also,
those specs say its bluetooth is version 4.0, but isnt the XPS version 2.1+EDR ?
Anyone successfully connected the Mediapad to a 5Ghz wifi AP?
(It should be supported according to the specs: 802.11b / 802.11g / 802.11n)
My Mediapad seems not to find the AP, while I had no problems with an ipad2 to connect to the same AP (channel: 48).
The AP does not show up in WiFiFinder either.
Any ideas? Thanks!
Mediapad wifi don't operate on 5GHz band, only 2.4GHz. The N standard don't mandate devices to use 5GHz.
I see. Thanks for the clarification!
802.11a is 5GHz wifi

so as n, which is dual band
The s2 has a Broadcom BCM4330 wifi chip.
This chip supports till 72Mbps connection, while I get 65Mbps max on my router.
The router is configured on 802.11B/G/N (speed: MCS7).
11N is 20/40Hz.
As I see on wikipedia here, that the speeds at 20Hz 65Mbps on 800ns GI and 72,20Mbps on 400ns GI
I am still getting max 65Mbps on my phone if it's connected to my extender which can get up to MCS15.
Is there a way to maximize connection speed?

in the WIKI link of ur post i see the below
Deployment strategies
To achieve maximum output, a pure 802.11n 5 GHz network is recommended. The 5 GHz band has substantial capacity due to many non-overlapping radio channels and less radio interference as compared to the 2.4 GHz band. An 802.11n-only network may be impractical for many users because they need to support legacy equipment that still is 802.11b/g only. Consequently, it may be more practical in the short term to operate a mixed 802.11b/g/n network until 802.11n hardware becomes more prevalent. In a mixed-mode system, an optimal solution would be to use a dual-radio access point and place the 802.11b/g traffic on the 2.4 GHz radio and the 802.11n traffic on the 5 GHz radio.This setup assumes that all the 802.11n clients are 5 GHz capable, which isn't a requirement of the standard. Quite a few wifi-capable devices only support the 2.4 GHz, such as iPhone 4S, and there is no practical way to upgrade them to support 5 GHz. A technique called "band steering" is used by some enterprise-grade APs to send 802.11n clients to the 5 GHz band, leaving the 2.4 GHz band for legacy clients. Band steering works by responding only to 5 GHz association requests and not the 2.4 GHz requests from dual-band clients.

my router/modem is 2.4GHz only (i think), I have the huawei hg655d.
so no possibilities?
ps on my pc I get 300Mbps connection (atheros ar5b93 wif card)
From what i read on the specs the Snapdragon 400(MSM8266) supports 2.4/5GHz WiFi bands and a/b/g/n/ac classes, but devices like Moto G (XT1032) support only the 2.4GHz band.
On the other hand devices like Xperia M2, that share the same SoC, apparently support the 5GHz band.
Is there some kind of software restriction to remove the 5GHz compatibility? I can't understand why it shouldn't work...
