I am new to the GS3 on AT&T (or will be when it gets here in the mail, yahoo!!).
I have been a Droid X user for 2+ years, on the Verizon network.
Jumped ship over to AT&T for discount reasons, and decided on the GS3. Wife's arrived last yesterday... horrible WiFi connection issues on our network, but the GS3 would identify both the 2.4 ghz and 5 ghz networks from our Netgear router.
After beating my head agains the wall, I ran the UCLH9 OTA update and if fixed the wifi issues, but all we can see is the 2.4 ghz network, and not the 5 ghz anymore.
Any ideas? Thoughts? Discussion?
More of a though than a solution, but maybe they decided to remove the 802.11a functionality from the radio since it is an antiquated standard, not to mention 802.11g for all intensive purposes is exactly the same only on the 2.4Ghz frequency. This could have also been handed down from higher up, from the IEEE or even FCC to make room on the 5Ghz band for new technology. New technology such as 802.11n which runs on both 2.4 and 5Ghz, i'm going out on a limb and guessing your router ins't wireless N capable or you would probably see this. There is also a new wireless standard in development (802.11ac) which will be exclusively on 5Ghz. Spectrum is like land, they* quit making it long ago...the only way to move forward is utilize what is there better and tear down the old stuff in favor of the new.
* I use the term 'they' vaguely, i'm not here to start a theological debate.
I believe our router (Netgear WNDR3700 Dual band) has both. I have a dell laptop that 'sees' both the 2.4 ghz and 5 ghz SSID's. So I'm relatively sure the router has both.
I was unaware that N technology runs on both the 5 ghz and 2.4 ghz simultaneously. I'll have to look into this to see if this is related.
The loss of detecting the 5 ghz still makes me go hmmm?
Thanks for the reply.
The router you listed is an N capable router, why your phone isn't seeing the 5ghz band i'm not sure. As my signature shows im running AOKP and the KT747 kernel which uses different wifi drivers. I currently don't have a wireless N network thanks to some lightning earlier this year to check, but i can say i've never had any problem with connecting to any wifi networks. I would start with the router and check the settings there as to how the network broadcasts, what frequencies its on etc. I have had problems in the past with running on the 20/40z frequencies so you might change that to 20 exclusively and see if that helps you.

Any one knows a good wifi router to get. I bought a Belkin and it sucks.
i'm using apple airport extreme right now. it actually has great range. a bit on the low side of the 'features' category but if you are looking for great hardware and crappy software, everybody knows apple is your man!
Imma have to look into that one. I was looking at a linksys. I heard they made good ones
The Linksys e2000 is fairly reliable if you don't want to spend a lot.

I have had this one for almost 5 years. I bought it back when it was like $90 I love it. It is upstairs in my room and I can still get the signal on my back deck outside. Not a bad unit I think, especially the price it is now.
I've been using this Linksys Router for a few years now:

I just purchased a Netgear WNDR37AV Dual Band router. I have it set up to run both the 2.4GHz and the 5GHz band at the same time. All my laptops (3) run off the wireless-n at 5G and our Blu-ray player and Evo's run on the 2.4Ghz band. Fairly easy to set up.
ZTE wifi router
I think ZTE is also a good brand for wifi router, such as the MF30 wifi router, it supports up to 5 users connected via Wi-Fi(including PSPs, digital cameras, laptops, and MP4s). Quad band GSM and tri band UMTS. Supports up to 32GB Micro SDHC memory. It can cover a 50 meter radius.
i recently got this one and am very pleased
http://www.amazon.com/Netgear-N600-Wireless-Router-WNDR3400/dp/B0041LYY6K
i didn't realize how important dual band was until recently.
I run 2 wifi networks off of this. i connect all my N-draft products to one and all my G to the other.
I recently learned that if you only have 1 band and connect a G draft product to it, it will bring the entire network down to G, even if the other products can run N.
Hope that made sense.
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?!
Chris.
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.

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.
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!

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.
So, I usually leave my phone on my wireless n/5ghz connection, and I get fantastic speeds.
I tried in on 2.4ghz today, and instead of getting my "normal" 60 down/13 up, I can't get anything faster than 5 down/3 up
I know its not my router, as its brand new, and I have it setup perfectly, and everyone else's devices in the house,(lg G2's, samsung tablet) gets GREAT speed on both 2.4ghz, and 5 ghz in the same exact spots.
I am only getting a 39 meg "Link Speed" on my phone on 2.4ghz, whereas the other phones in the house are getting a 96 meg "Link Speed" on 2.4ghz
I've tried all the advanced wifi settings on the phone, including going from auto to 2.4 only, and the speed is still horrible.
My previous phone, an LG Flex, also had great speeds on both 2.4ghz and 5ghz..
This is a completely stock t mobile m8, only 3 weeks old, so I am wondering if the phone is bad, or if these phones just have poor 2.4ghz wireless radios..
Anyone see the same problems with thier M8 and wifi speeds on 2.4ghz?
Same problem for me since 4.4.3 i must switch wifi off on to solve the issue and after a while problem returns.
Setting a static ip in settings helps a little.
Sent from my HTC One_M8 using XDA Free mobile app
yeah, I wonder if it happened when I got 4.43 a few days ago; I never bothered to check it until today..
thanks
I see some one else posted a similar wifi speed issue; there must be more folks who had this problem since the 4.4.3 update..
Is this max network speed for a70?
This is screenshoot form wifi settings.
On other phones i get 130mbps.
mine says 65. Ultra slow downloads. Heard some people talkin about using the 5 Ghz band of certain equipped routers or n band. It is just so slow downloading from my wlan I figured it must have something greater wrong with it. Like hackers again...who knows.
This is what mine says
On mine is 72mbps network speed and cant get over 49mbps download speeed on speedtest.net
433Mpbs on 802.11AC for me
I get a picture 130 mbps on my oreo device but both pie devices say 65 mBps.
My 1000/100/10 switch connects ethernet to various devices which easily shuttle the expected 80-130 actual MB/s around of large filetypes.
I don't have any sort of 5 Ghz router just the crappy device that the company sent out. And on that the MAC filter keeps getting disabled which increases my paranoia. Till 2 weeks ago I used the same crappy standard gateway/router for 6 years and frankly it was equal or better experience. At least that one started up reasonably fast. And its MAC filter was always on. But that could just indicate that the neighborhood brats had an easy backdoor to that one and didn't have to brute force off the MAC filter.
In my opinion the MAC filter getting disabled (now a few different times it has happened) indicatives a much much larger problem
I have been intending to get my own personal router for a while but there are too many options so I haven't had the scope to choose one yet.
Other phone in network displays 117mbps and is a Pie.
On same network 2.4ghz on s8,s7 i get 130mbps and on a70 72mbps max.
Just tried 5ghz on same network and got 150mbps it is a little faster.
But on 2.4ghz 72mbps is max.
hi guys
i have also same problem . cannot connect more than 72mbps , with 5ghz 150mbps max . something wrong but i could not find what is the problem .

i think all a70 phones are like that
I just tested and got 158Mbs with a 5Ghz wifi connection, although only around 60Mps on 2.4Ghz.
Andre
I'll check mine later and see if I can figure out what's happening
Right next to the router I can see 96mbps in 2.4Ghz
Must be something wrong. I got 433mbps.
Nothing is wrong.
The Snapdragon 675 supports 2x2 chains on WiFi, but the A70 only has a 1x1 antenna so it connects at half the speed.
Link speeds on the A70 are as follows:
2.4 GHz = 72 Mbps
2.4 GHz (with 256 QAM) = 96 Mbps
5 GHz = 433 Mbps
On all devices with 2x2 on WiFi, the speeds above will be doubled on those.
These are in ideal network conditions with great signal strength and low interference. These numbers could reduce if you are far from the router.
This is not abnormal. A lot of mid-range devices only have 1x1 for WiFi.
