Does Nexus One Froyo have 802.11n?

I'm connected at 54Mbps only. Is there something I need to do to enable it or does it not exist?

Do you have an n router?

Sorry, my bad. I had my settings all messed up from the router. Got it working. Thanks anyway.
Mods, please close =)

Nope, it's time to shame you.

Am I the only one that could connect to an N router (set up to allow ONLY N connections) when I was on my brand new EPE54B 2.1 Update 1 AT&T Nexus One when I got it 3 weeks ago?

I can connect to my N router at ERE27, with 65Mbps connection speed

i quess 2.4Ghz? Not the 5..Ghz right?

I can connect to wireless N with my ATT Android 2.1 too

I've got a dual band router. It will not see my 5ghz N band, but will connect on the 2.4ghz band. Fastest i've seen it though is 72Mbps

Does not see or connect to my 5GHz n network.

If i remember correctly, the N1 is missing an antenna for it to access a 5GHz wireless-n signal. Just like my netbook which sucks since my entire university has a 5 GHz wireless-n signal but not 2.4 wireless n

That sucks. The whole point of n is the 5GHz spectrum.

802.11n support is only on the 2.4 GHz band. 5 GHz band is not supported.
Also, it's a 1T1R radio (one spectral) vs. 2T2R (2x2 MIMO) like most common 802.11n consumer products meaning it's limited between 65 to 72 Mbps.

WiFi 802.11n

This question has probably been asked before, and i'm sorry for repeating it, if so.
But can someone tell me if it's even possible to get more than 54Mbps in link speed on A101?
I've seen screenshots of link speeds at 65Mbps, but i can't get higher than 802.11g speed. And, yes i know that the link speed is just a theoretical speed, but since this device is supposed to be able to handle 802.11n (at least for my knowledge), it would be great to get n speed working. My wireless router is a Netgear WNR1000 v3.
Thanks in advance.

But i think the WNR1000 runs at 2.4GHz. Not 5..

I'm on 2.1.03 and my 101 connects to my d-link router via 802.11n (confirmed on the router) but the 101 says 54mbps reguardless of actual rate.

Apparently, the max speed on this device is 65 mbps because of a hardware limitation. I think this is total BS because this device is marketed as supporting wireless N. The only real difference between N and G are the speeds, so saying that it supports N and not having it support the N speeds is really retarded.
Then again, I could be misinformed. I hope I am, but AFAIK, it's a hardware limitation.

Doesn't [email protected] require 40MHz channel width? Maybe the tablets don't support 40Mhz channel widths.
**EDIT**
Just set my wireless to 40MHz channel width only and the archos connected fine.
Just because the box says it supports 802.11n wifi networks, it doesn't however, make any claims as to the rate at which it connects to such networks.

I'm a little disappointed that archos chose to implement the bare minimum to qualify for 802.11n. If you do actually read the N white-paper, it doesn't really REQUIRE all that much. It doesn't require 40mhz, and it certainly doesn't require higher speeds. There is MUCH more to the N implementation than just throughput. However just doing the least amount of work to get your N badge is disingenuous.
I've connected my 70IT to a Cisco controller based network that I administer, and I can't get above a 54mbit connection either connected to a 1252 or a 3500 series AP with a 4400 WLC all on the newest code. I do connect at MSC07 which is an N code. I only have 20Mhz enabled on my 2.4 band though and will not be able to test 40Mhz...
I'm not certain if they can make updates to software that can add more N features or not. If so, I wish they would add it to their TODO.
I can't post a link to the whitepaper being a new user, but google for
802.11n mandatory optional whitepaper
and you'll find it on the 2nd link.

Ok, thanks for the information. To bad it seems that i have to stick with g speeds.

[Q] 5GHz 802.11n

I can't for the life of me get my Xoom to see my 5GHz 802.11n network... I have a Linksys E3000 running dd-wrt with one of the connections doing g/n mixed and the other doing straight up 5GHz n. It works fine when I connect with my laptop. The Xoom will of course see and connect to the g/n mixed network no problem using 2.4GHz n.

Are you using 40 MHz channel bandwidths?

Yeah, I've tried 40 MHz both upper and lower and 20 Mhz.

My xoom sees my 2.4 network with full bars, 5ghz at 50% power even though I am in the same room with the access point...

do you have any other devices hooked up to the WAP?

Does the fact that the Xoom's wifi radio is 2.4ghz N make a difference?

No, this is the only device.

I don't have a xoom, but with my X I had to remove a dash from my SSID. I also swear for 5 minutes my X saw my 5ghz band (my router does both simultaneously), but I guess that could have just been the router broadcasting the wrong SSID for the 2.4ghz.

FWIW, I have an 802.11a (5GHz) network at home (nice, 'cause my a-capable WiFi devices don't have to compete with the other ~15 visible 802.11g networks in my area) and I was able to connect to that right away. Pretty surprised, actually, but the BCM4329 is an a/b/g/n capable device, after all.

I'm currently on a 5ghz n only network without issue. Netgear wndr3700.

Just wanted to update everyone in case others find this thread looking for help that I may have found my solution. I came across a post on the Motorola forums that mentioned needing to set the channel to one of a handful of channels, notably, one of the following: 36 40 44 48 149 153 157 161. My router is currently set to auto and I have confirmed it is not on a compatible channel at the moment. Unfortunately, I will be unable to test this to confirm it is the problem until I get home in a few days. Will update again then.

Where did you see the specification that Xoom's wifi radio is 2.4Ghz? Especially since some people are connecting to their 5Ghz N routers.
Please see: https://supportforums.motorola.com/thread/46417?tstart=120

Most WiFi IS 2.4GHz; what sets the Xoom apart is we have the 5GHz "N" and "A" bands, too.

Update: Well I'll be damned, that's exactly what the problem was. Changed my channel from Auto, which had selected channel 56 which supposedly is not supported, to channel 48 which supposedly is supported and it showed right up and connected no problem.

[Q]5Ghz wifi

So I've been digging into this a bit the last couple of days, and as far as I can tell the Nexus 7 doesn't support wireless N on the 5ghz range, which is sad.
I dig into this, and find others are finding the same: http://forum.xda-developers.com/showthread.php?t=1803798 http://forum.xda-developers.com/showthread.php?t=1777431
However, I have also looked into the chipset, and AnandTech.com, http://forum.xda-developers.com/showthread.php?t=1749498, and the Ifixit teardown agree that it is using a BCM4330, which supports Wireless a/b/g/n 2.4ghz and 5ghz, as well as bluetooth 4.0, and fm radio. I took a look at the radio, and the creator of SpiritFM has concluded that the chip's antenna pin isn't connected, and thus why FM isn't working.
So, my question is then; is the lack of 5ghz on the Nexus7 a hardware or software problem?
It would be nice to have the 5ghz wifi range, as my college campus actually uses it a lot.

It's a hardware issue, and I don't think the lack of 5Ghz is a problem when you consider that the wifi chip only supports single stream at a maximum 65 Mbps. There are a few other devices out there that can support up to 72 Mbps, but that's about it. Tablets and smartphones are almost always a few years behind the standards because it's incredibly expensive to manufacture wifi hardware capable of the latest and fastest standards that will fit inside of a mobile device.

Is there any evidence that its a hardware issue? The chip seems to support it, as i said.
People thought the htc dream (tmobile g1) would never run ics or jb, guess what it can! Not well, but its possible.
So why isn't 5ghz possible? No offense, but 1 person saying its not without any clear evidence wont get me to give up.
I never said speed was an issue, its mostly compatibility, cant hardly connect to campus wifi if my device doesn't support 5ghz; and the 2.4ghz bands are crowded in my apartment complex, a single 5ghz router would do wonders.

The important part to note is the "or" in the middle of that statement, which means that there are two different versions of the chip. The HTC One X, for instance, has the dual band version. We've got the cheaper single band version in the Nexus 7.

802.11ac highly underrated with Galaxy S4 launch?

I personally think that this is a major milestone for any mobile phone yet, no one seems to be talking about it. Why is that?
Isn't this sort of stuff supposed to make waves in getting 802.11ac into mainstream use? These are the type of headlines that should be discussed to death and made a big deal out of yet it just had a little mention in the launch and not a lot of new stories about what draft it was and which routers today would be best suited etc etc.
Discuss please?

Ok agreed, this is a monster on paper, but it will be suitably replaced next year with a 16 core device maybe. or better yet, some sort of cloud service driven by LTE network speeds with hundreds of supercomputers working in tandem, only to fall back on local CPU power if the cloud is not available or loss of signal (I love speculating).
BUT !!! and its a big BUT!, 802.11ac will be here for a good few years, way past the Galaxy S4's shelf life.
This phone will drive the prices down for ac wifi routers and hotspots, however I dont think that this is the final version of 802.11ac which is why they are all hush hush about it?

Launching
I can't wait till April. The launching of the new Samsung Galaxy S4 is one of my most awaited event. This phone is taking us to the next level folks!

Are you saying that there will be no 16 core CPU's in the future? Its like Bill Gates saying back in the 80s that no one will ever need more than 8kb of RAM. If you are referring to the S4, yes, I know 4 cores for processing and the other 4 for battery saving lighter tasks. This however has not stopped Samsung marketing the device as an 8 core beast.

Only because they are bloody expensive to buy. What if the S4 can turn this around and make these affordable for all? With the launch of this device, maybe, just maybe, the following happens
1. Demand intensifies
2. Competition want to offer the same functionality and hardware (APPLE, HTC, NOKIA, HEAIWEEEEEEEEEE, LG)
3. Hype and buzz intensifies
4. News stories pop up all over the place faster than ever about the AC spec and how amazingly super fast it is
5. A lot of manufacturers trialing and testing AC routers and hardware
6. Prices become affordable as volume units start making their way worldwide
7. Price come down futher by retailers trying to outsell each other with deals / discounts / coupons / promotions
8. Eventually ISP's start giving these out for free to their ADSL and fibre customers
9. People begin to reap the benefits of up to 1.7GB speeds over wifi
10. The whole world forgets about 802.11n like it never existed

Wonder why this thread has made its way to the Q&A troubleshooting area?

To be honest 802.11ac in the first wave is going to be kind of pointless. In reality it is basically just 802.11n with wider channels. 802.11b ---> 802.11g are big changes. 802.11g ---> 802.11n are big changes. 802.11n ---> 802.11ac, not so much.
It doesn't say buy I am guessing it is going to be a 1x1:1 like the SIII. I would rather have a 2x2:2 802.11n that a 1x1 802.11ac
Here is how it works out.
SIII - 802.11n 1x1:1 at 40mhz = 150mbps
Nexus 10 - 802.11n 2x2:2 at 40mhz = 300mbps
S4 - 802.11n 1x1:1 at 80mhz=325mbps
the Nexus 10 has two antennas and radios compared to the SIII or S4. It should be able to hear and transmit better.
WiFi has a **** load of overhead so you normally get about half of your connection rate in real throughput. With that said I only get about 90mbps with iPerf when my Nexus 10 is connected at 300mbps. It is like the bus on the thing can't hang. Copying files from a server with ES file explorer is super slow.
I haven't played with an s4 but the bottleneck on the other devices isn't the wifi.

AC router
I currently own an AC router... Since I live in the UK and Broadband Speeds are just well totally b**l s**t, there's not really much of a point of ac on that basis N is more than capable of reaching speed of up to 300 mbps
Till broadband speeds dont catch up with the N there's not much really any point of ac
only time i think ac will actually benefit a user is particular when media streaming or wifi file-sharing and that also having the actual host connected via Ethernet or ac.

So what? The majority of internet service providers in most countries don't even provide enough bandwidth to saturate 802.11g.
802.11n and 11ac are good for transferring huge files from a desktop to a laptop, but really, not of much use on a phone. g alone is sufficient to stream a 1080p H.264 stream.

I'm located in the USA and currently using a Netgear R6300 AC Dual-Band Router and can only get the S4 to connect at 802.11G @ 54Mbps. I see no options to change the band speeds to 2.4Ghz/5Ghz which 802.11AC runs on the 5Ghz band. Very disappointed on Wifi and feel Samsung made false advertising... I realize AC is technically [draft] but the S4 should atleast connect using 802.11N.
