Anyone been able to connect to a 5GHz WiFi network witht the Galaxy Nexus?
Forcing the "Wi-Fi Frequency band" setting to 5GHz only just results in an empty list of available networks, despite the phone being sat underneath a very decent enterprise-grade dual band AP (Ruckus 7363, Atheros chipsets). Have tried a bunch of different channels on the Ruckus AP (in both the 36-64 and 100-136 range) and switched between 20 and 40Mhz channel widths to no avail.
As far as I can tell, the Galaxy Nexus uses a BCM4330 chipset should have a 5GHz amp, would be ashame if there's no 5GHz antenna for it?!

My bad. Think I was changing channels on the wrong AP when testing out 5GHz earlier.
The Galaxy Nexus does indeed support 5GHz, albeit on a limited number of channels (connecting at a 65MBps maximum datarate):
36
40
44
48
Just to finish up on this: After a bit of testing with an iPhone 4s (which also uses the same BCM4330 chipset and has no problems with any 5GHz channels), I'd guess that the GN's apparent limited support for 5GHz wifi is down to a software issue.
Basically the channels it supports are the ones that don't require DFS (Dynamic Frequency Selection) to be enabled on the AP, for use in the US (Europe apparently doesn't care about DFS).
I'd guess that the driver as is doesn't support interop with DFS (which I'd assume should be an AP-side function anyway) and rather than trust me that I'm in Europe, it just prevents those channels from being used.
Ashame, as it means 5GHz support is basically broken when it comes to using it with 'enterprise-grade' kit (not sure if consumer APs generally support DFS or not).
it should work with 5 Ghz WiFi
even the SGS2 works with 5 Ghz WiFi
at home i can connect using my 5 Ghz WiFi

Hmmm...there's something odd going on with my GN with 5Ghz Wifi - I have a couple of Netgear routers 802.11N running on channels 36 and 44 and the GN connected no problems for the first few hours, but now it just won't grab an IP address. I've resorted to the G channels on 2.4Ghz, but have no idea why the handset suddenly won't pick up an IP on the 5Ghz even though I'm getting 'excellent' reception.
Any ideas? I've rebooted the phone and the network. The Mac and the iPad are the other devices on the 5Ghz and they're fine...

Have you check if it's not just your Regulatory domain settings that are wrong? I don't have a GN yet so I can't check but used to be under Advanced in Wifi settings.

It's very strange (I've got older DNDR3300 and WNDR3300 in the house) - it can see the SSIDs for 5Ghz, but just won't allocate me an IP address...I've looked at the wifi diagnostics through the *#*#info#*#* and there's nothing I can really do. I'm taking the thing back to '3' tomorrow.

have you tried allocating it an ip address manually in the router, basically forcing dhcp to allocate a specific one? Did you try connecting with no encryption as well (def worth a go)

Yup - did all that. turned off encryption, added guest networks, turned off DHCP and entered manual IPs. The GN picks up the G and obtains the IP address no problem, but it just won't with the N...

Bummer. assumed you would have had done all that..
Just to add to the body of knowledge surrounding this. I have an Airport Extreme (Gen2), which had a recent firmware upgrade. This set it's automatic channel selection to use channel 100 - which my GN could not see. It took a downgrade from 7.6 to 7.4.2 for it to use channel 36 - and now I'm happy and connected. (I have other b/g APs in the house, but its nice to be on the fastest!)

Was it a case that the GN could not see your network at all before?
I mean, my GN can 'see' the N networks, it just won't grab an IP - it just says 'Saved, secured WPA2 etc...' and will not obtain an IP.
I'm gonna replace the handset soon anyway with the volume 2g problem.
For reference: The 5Ghz spectrum isn't required to use N-based routing. It'll give you a bit more distance and speed, but not very much (think in the range of an extra ~10%). It's a misconception that 5Ghz is the only way to use the N-band.
As far as distance goes, that shouldn't really matter for your phone unless you're on the absolute fringe of the range. As for speed, you'll absolutely never notice a difference using a phone. The only time you'd notice a difference in speed is when transferring large files from computer to computer (or if your data connection is upwards of 25Mbps, but this wouldn't matter for the phone, either).
OK, if this is just for reference, we'd best get it right ;-) All slightly off topic, but it goes someway to explaining why having the GN support for all the 5GHz channels would be useful.
Signal propagation at 5GHz is generally worse than at 2.4GHz. All other things being equal (xmit power, antenna gains, interference, etc) a 5GHz signal will actually have less range than a 2.4GHz one.
The 2.4GHz/5GHz issue isn't so much about range or relative throughput in the best case scenario. It's about the worst case scenario - what happens to your speed when there's interference.
The 2.4GHz band has three, useful, non-overlapping 20MHz channels (1,6 and 11). 5GHz has around 19 non overlapping 40MHz channels (of which the Galaxy Nexus supports a measly four) *and* a scheme for dynamically avoiding interference on-the-fly (DFS).
This translates into significantly more stable performance on 5GHz compared to a congested 2.4GHz band (as it is in most built up urban areas - eg I see about 30APs broadcasting on 2.4Ghz now from my home in central London).
TLDR; If you live in a field - 2.4GHz is fine. If you live in a city, 5GHz is the future.
I'd suggest the following for a good bit of background on WiFi, along with some useful benchmarks showing just why most domestic APs/Wifi routers are crap in any case:

Setting my Linksys 610 DDWrt router to channel 36 with a channel width of 40MHZ did the trick. Thanks!

Does anyone know if the "measly four" is a mistake by the firmware, a regulatory thing or just a hardware limitation?
My router performs best at channel 161 (it's a DD-WRT firmware thing) which means I can't see it on my phone, but I'm fine to access it on both my netbook and laptop.
Just want to thank the OP for this truly excellent thread. I also uncovered that the GN can also connect to the UNII-3 and the 5.8 ISM bands (channels 149-165), which are also non-DFS.

Seconded, I must have missed this post originally. I was pleasantly surprised to find that my GN connected to my Linksys E3000 running DD-WRT on channel 161 (40 MHz width).

Thank you very much. Simple, concise, worked perfectly. Cheers mate.
802.11n includes a number of "optional" features, so how much of it does the Galaxy Nexus actually implement?
My Wifi router supports 2.4GHz and 5GHz bands simultaneously with different SSIDs, but the Galaxy Nexus only ever sees the SSID of the 2.4GHz AP. So I suppose it does not support 802.11n in the 5GHz band?
Also, even when standing right next to the router, it showed only a 65Mbps connection. Shouldn't that go to at least 150Mbps? And actually higher if MIMO is supported?
If the Galaxy Nexus' "802.11n" doesn't support anything better than 2.4GHz band with 65Mbps, it's a fake - 802.11g does 2.4GHz/54Mbps, so the "802.11n"-support boils down to be effectively nothing.
Has anyone managed to get better Wifi results with the Galaxy Nexus?
i think the gnexus is only supposed to support 2.4ghz band if i remember correctly. i get the same, 65mbps. all is good though i get great speeds and more distance. if 5ghz is in the hardware then software doesn't support it yet.
It does support 5ghz. Go to settings and then press wifi. Press the menu on the bottom right and select advanced. Then, wifi frequency band.
Weird... My WNDR3700 running DD-WRT is setup for 2.4 and 5GHz... My MacBook Pro is connected to the 5GHz SSID, but that is not displaying on my available wireless networks on my GNex...
The wifi settings are set to "auto", but even when set to only use 5GHz, it still doens't list it.
I'm connected to my 5GHz network right now so yes it does support it.

I'm connected to my 5Ghz network as well, however I'm only seeing 65 Mbps connection speed. Are you seeing a better speed?
Wi-fi performance for file transfers have been pretty abismal. Using the app andFTP and the sftp protocol I can only get about 1300kbps download speeds.
I get a weak WiFi signal on both spectrums compared to my DInc, DX, & DX2.

My Galaxy Nexus connects to my 5ghz just fine. One problem though, the phone shows signal of my 5ghz lower than the 2.4ghz in the same spot and I'm meters away from my router.

I've been playing around with WiFi - stock Verizon GN, 4.0.2. Cisco/Linksys E4200 DualBand Router.
Using WiFi Analyzer, my GN sees both 2.4GHz and 5GHZ bands, with the 2.4GHz band being slightly stronger (-46 dBm vs -15 dBm, for example). When WiFi Band Selection is set to Auto, it will connect to 2.4GHz every time. If I change it to 5GHz Band only, it will readily connect to that band.
Using Speedtest.net, I get Download speed of around 6mbps with 2.4GHz, if I force it to use the 5GHz band, I'll get over 30mbps. This was tested 3 times, semi-randomizing the sequence.
The range of 5GHz is obviously less, so it would not be practical to leave it on the 5GHz band only, as I'll need the 2.4GHz elsewhere in my home.
For what it's worth, I'm using Channel 11 on 2.4GHz and Channel 161 on 5GHz. I saw a few threads where only certain 5GHz channels are supported for connection, and those didn't include 161, but mine will connect fine. It's just that it'll go for 2.4GHz when given a choice, and a slight differential in excellent signal strenth.
Is this just the nature of the beast? Anything I can do to have it "prefer" the faster 5GHz band, while allowing it to connect to 2.4GHz when needed?
Hello again
Typically when dealing with 2.4Ghz vs 5Ghz, you would assign different SSID's to each. That way you can control which network you associate with. As you already stated, you understand that 2.4Ghz has a greater range than the 5Ghz network.
As we discussed before in the other thread, wifi likes to hold on. However, it will show a preference to 2.4Ghz bands when signal strengths differ.

Very interesting, thanks for the information! I also have the same router and when I return home tonight, I will assign a different SSID to the different bands.
Thanks!
i have two names for my WiFi at home: sausage fingers (2.4) and because racecar (5) lol

Funny running into you here!
I can play around with using different SSID's, but I'm guessing my GN will still choose the 2.4GHz if given the choice, since its signal is a bit stronger. If that's the case, then I'd have to manually have it connect to the 5GHz band anyway, little different from my current situation.
Too bad the WiFi settings don't allow us to prioritize our connection preferences.
Thanks again.
Please ignore this post.
I have a similar experience
sent from my googletron
Just to provide some follow-up here, I was able to more or less improve the situation.
On my Linksys E4200 Router, I changed the SSID on the 5GHz band, and removed the SSID oif the 2.4GHz band on my GNexus. So downstairs, it will automatically see the 5GHz band, and will connect to that, providing superior throughput.
I have the Netgear Wireless Adapter upstairs also on a different SSID (this is a 2.4GHz band), and when I go up there, the 5GHz signal is pretty weak, and so my GNexus switches to this fairly quickly. Not immediately, but pretty quick.
When I return downstairs, same thing - it will switch to the 5GHz signal reasonably quickly, especially if I sit down at my Computer, which is just underneath the Linksys router.
Hope this might be of help to somebody.
Like the title says, does anyone know for sure if the 900 supports 802.11n over 5ghz instead of 2.4ghz? been searching and i can't seem to find anything.
Thanks in advance

it does not. Samsung focus s did. The hd7, lumia 710 and 900 do not.
I can confirm. My Focus S saw and connected to my 5Ghz wireless with no problems.
The Lumia 900 doesn''t even 'see' it.
Just out of curiousity, what would you do with an N connection on your phone?
Just curious, not judging or questioning your need.

I assume you're asking why would I need a 5GHz connection and not a 2.4GHz connection: both can be 802.11n.
The reason is simple in my case. From various spots in my apartment, there's upwards of 25 different wireless connections on the 2.4GHz band. There's zero on the 5GHz band. If I'm connected on 2.4GHz, I'm lucky to get a signal 20 feet from my router.

No, I am asking what the benefit of a potential 300MB(N) connection VS 10MB(B) or 54MB(G) to a cell phone would be considering most home internet is in the 1MB to 10MB range.
So essentially, what does one need a 300MB connection to their cell phone?
However, in your case I assume you only have N on the 2.4G band and no B or G ?

I think it could be useful if you do the "Wireless Sync" option with Zune. 300MB/s internal network speeds would make wireless syncing a lot faster.
But now that I think about it - since wireless syncing usually happens at night, while you're asleep, and your phone is charging... super fast speeds probably aren't need anyway.
Is it possible to serve a hotspot on both 2.4ghz and 5ghz frequencies at the same time?
I need 5ghz for LTE speed but I need 2.4ghz for a printer.
Is it a limitation of hardware that there's no option to select both in Lineage?

Two simultaneously operating Wi-Fi hotspot transmitters means high power consumption and heat emission.
I don't know a smartphone that had such a possibility.
I'm skipping the fact that there must be two antennas in the device, which must be far away from each other to avoid interference.
Rather look for a stationary router that will meet your expectations.
