How fast is Galaxy S2 Wireless N?

I have just got a new broadband contract with O2, here in the UK.
I have a wireless Box IV (4 in roman numerals) which supports wireless N.
My phone is connecting to this wireless box at 65mbps. I had expected it to connect significantly faster, because wirelss N supports up to 300mbps.
Can anyone tell me what the fastest wifi N signal available on the phone is?
Thanks!

Mine is consistent @ 65Mbps also.

Never seen mine higher than 65 mbps.
Using an AP D-Link DAP 2553 (Wifi N 300 mbps max) at 2.4 GHz

As far as I know the fastest available Wireless N-chip on any phone is 65mbps. If what I've read is correct this is because phones only have 1 WiFi antenna and speeds higher than 65mbps requires multiple antennas (google "MIMO").

is the galaxy s 2 Draft-N or 5.0GHZ N ?

Thanks guys. Ok, it's good to know it's not a problem with something.

I don't understand your question, SGS2 is dual band (2.4GHz N and 5.0 GHz N).
N-draft is gone since a long time ago, the N-draft standard was approved so basically all units sold as N draft is also "pure" N. But support for 5 GHz is always optional.

65mbps also.

[Q] 5 G Wi-Fi (802.11ac)

does Nexus 4 has 5 G WI-FI (802.11ac) chips built in ?

i thought its just b/g/n but Phil Nickinson (AndroidCentral.com) states it does

Yes the nexus 4 does have the 5ghz band. It is under wireless, and from there it is under advanced settings

guys, forgive my ignorance. Im a little confuse here.
Just for clarification.
In tech world terms, is the WIFI 802.11ac chip is the same as a dual band wifi 2.4 and 5 GHz chip ?

5ghz is not ac. Both n and ac use 5ghz, but they're not the same thing. It's like how wireless a, b and g use the 2.4ghz spectrum but they're not the same standard.

so in conclusion in this thread, the Nexus 4 does not have WIFI 802.11ac chip but has a WIFI 802.11n dual band chips.
by the way, which do you think is better in a smartphone device in the future?
a single band 5GHz WIFI 802.11ac chip or a WIFI 802.11n dual band (2.5 and 5 GHz) ?

802.11ac will be available in the Snapdragon S800, the technology was "apparently" not available when the S4 Pro was considered.

I do not believe the Nexus 4 supports AC. However it does support 5GHz 802.11n

I know that it might be off topic, but I think that most wireless routers you'll encounter today - and a couple years from now - will probably not even have dual band, let alone 802.11ac. I'm not trying to push back technology but it takes two to tango, and most routers aren't in a "dance" mode.

wifi speeds

wondering what wifi connection speeds people are getting on their oneplus 2,
according to ifixit teardown it has a Qualcomm QCA6174 802.11ac Wi-Fi 2x2 so it should have two antennas.
https://www.ifixit.com/Teardown/OnePlus+2+Teardown/45352?utm_source=oneplus2teardown&utm_medium=Description&utm_campaign=YouTube
but I am only getting single antenna speeds, same connections speeds as G4 and basically half of the speeds I got with my nexus 6.

I also would like to know oneplus 2 wifi speed. Seems like beside Samsung Galaxy S6 or Note 5, all other smartphone today can only support 802.11ac up to 433Mbps. Hope Oneplus 2 support 2x2 866Mbps.

I am getting half or less the speed I get with my Oneplus One! ! Tested both a few minutes ago, 21mbps on the 2, 68mbps on the OPO. Seriously.

Same issue, 1x1 speed @433 instead 866. Pfft.

Maximum AC wifi link speed?

I've been searching for a while and i just cant seem to find the answer. I just upgraded from an AC 1200 to an AC 1900 router. My note 4's wifi link speed on the AC 1200 maxed out at 867 mb/s. on 5ghz which is the max for AC 1200.
Now with the new router it still only connects at 867mb/s and not the max link speed the new AC 1900 router should provide.
I know it dosent matter, has nothing to do with why i bought the router and is plenty fast enough... but it's bugging me.
I just want to know if the N4 tops out at 867mb/s? Has anyone gotten anything higher for a link speed?
thanks!!

I certainly haven't gotten anything higher than that with my RT-AC87 and my Note 4. Only topped out at 700-something Mbps while being in the same room as the router itself.
Usually, the bandwidth numbers on these routers are inflated for marketing reasons anyway. Sometimes they mash together the total theoretical bandwidth for the 2.4 GHz and 5 GHz bands, sometimes they assume you're using 3x3 clients (I'm pretty sure the Note 4 and most other smartphones and laptops are just 2x2), and sometimes they conveniently ignore the fact that Wi-Fi is an inherently half-duplex connection (transmit OR receive, not both, so your bandwidth's halved for bidirectional communication).

Your new router is probably only a dual band. Two channels of 433 Mbs. = 867Mbs. I have a Nighthawk Tri Band router which will combine 3 channels to allow 1.3Gbs. However I have no devices that support triband connections. My Surface Pro 3 and Samsung Tab S only connect at 867Mbs. Even the new Note 5 specs say Dual Band for the .AC radio spec. I haven't seen any new phones with a Triband spec yet.

Le pro 3 wifi ?

Hi.
I am getting 50 to 70 Mbit/s wifi speed with my Le Pro 3 Al.
How come i can't get any faster wifi speed ?
And how fast wifi speed do you get in 2.4 and 5.2 Ghz with your Le Pro 3 ?

90.7 Mbps down and 10.6 Mbps up on my x722 on 5 GHz. Tested with the Amplifi app (for Amplifi routers only). But there are a lot of factors at play when it comes to Internet connectivity. Like the speed testing website or app you're using, as well as your proximity to your router.
My router is about 10 feet away from me. If my router was in the living room (I'm upstairs), I would be at around 30 to 50 Mbps down right now.
Also, add peak times for your ISP to the list of factors. My ISP (Rogers)'s peak times are in the evening. That's when everyone here is streaming Youtube and Netflix in HD. Some ISPs will throttle you during certain times too.
Another factor could be your Mediatek processor and your device's WiFi chipset. When it comes to wireless or LTE, Qualcomm has it down pat. I saw that the Pro3 AI does have MU-MiMO and two-stream WiFi like its Snapdragon counterparts, but I can't find any official specs on it.
Have you tested other Android devices on your WiFi connection? You'll know if it's just your device with those speeds then.
