Does the HD7 really do 802.11n? - HD7 General

Until recently I was using Connectify to set up a home wifi hotspot for my phone (TMOUS HD7, running 7720 with the latest T-Mobile/HTC firmware) to use. Yesterday I installed a router instead, which has allowed me to play with more network settings.
If I set the router to 802.11n-only, my HD7 can see it but can't connect. If I set it to 802.11g-only, everything works fine. Has anyone actually confirmed that the HD7 can do "n"?

my home wifi network is "n" and both my hd7's connect to it fine.

I have forced the n-mode, no problems connecting

Yep, Wireless N works perfectly fine here

Which 802.11n are you talking about? 2.4Ghz works but 5Ghz won't. so it only does draft n not full 300mbps 5ghz 802.11n

You are comparing two different things, WLAN standard has nothing to do with frequency, HD7 follows IEEE802.11b/g/n standard operating on 2.4 GHz with 20/40MHz bandwidth, allowing maximum throughput of 150Mbps. It is capable of DSSS and OFDM modulation, and is also capable of operating in dualband mode, which allows it to connect to 2.4 GHz and 5GHz IEEE802.11a/b/g/n networks, this is however up to the OEM to enable this feature, this is not the case for HD7, or any WP7 device out there.

Draft-n was 2.4ghz 150mbps was it not? where as full rate 802.11n is 300mbps and operates at 5ghz?!

Well, yes and no, 802.11n is capable of data rates up to 600 Mbit/s, those are achieved only with the maximum of four spatial streams using a 40 MHz-wide channel. However, when in 2.4 GHz enabling this option takes up to 82% of the unlicensed band, which in many areas may prove to be unfeasible. I don´t have device which is able to be set to achieve this limit (2.4GHz / 40MHz with 400ns Guard Interval), so I can´t test it. Do you have internet connection that requires such a high value?

[Q] Can a Nook do better than 54 mbps Connection

Wondering if there is anything that can be done to get a Nook to connect at faster than 54 mbps G speeds? Does it really have a N wireless chip? I have searched and searched and cant find an answer to this.
According to the spec sheet, the wireless radio chip does support N. I'm not sure whether the software supports it
Radio: Chip ID Ti wl1271 (kernel reports wl1273) Chip supports bluetooth transmit/recieve and fm radio functions through the same antenna, but is not enabled in software drivers. Connectivity: 802.11b/g/n Security: WEP/WPA/WPA2/802.1x Mode: Infrastructure

I get N connectivity via CM7 - been so long since I ran stock that I don't recall.

Yamadog, do you currently have a n router that you are trying to connect too?
I've read before that the Nook Color wifi chip only supports 2.4 GHz range (which is used for both 11g and 11n) but not 5 GHz range (which is only for 11n). If you have a b/g/n/ router running in compatibility mode for all three types then it might possibly be doing 11n only at 5 GHz and 11b/g only at 2.4 GHz and so your Nook would never be able to see the 11n signal. Try putting your router in 11n-only mode and see what happens
I'm on CM7 and I've never seen a rate above 54mbps regardless of N availability.

I have no problem with the connection its just it connects at only 54 mbps which limits download speeds to around 11 mbps Max. My computers connect at 270 to300 mbps at download at my full 24 mbps speeds. I did have a g only router and it limited my computers to only 11 mbps like the nook. Aipparently the g rating of 54 mbps is just under ideal lab conditions and not really obtainable.
According to my home N router, the Nook Color connects at 54mbps but N is in use. For some reason that is the max rate it will use. I've seen this happen with other N devices when WMM is disabled on the client.
Whoa sorry never really answered you. My router is a cheapo 2.4 ghz n but it does allow 300 mbps connections. I have to run it in b,g,n mode because our wii is only g wifi.

I bet that's the case with mine too, but I haven't checked. It does pick up signals like its running n though.

802.11n operates on both 2.4GHz (20MHz bandwidth) and 5GHz (40MHz bandwidth).
Anyway, how do you guys check out the rate on the NC?

I know, but I've heard of routers that do compatibility mode by segregating g and n between the 2.4 and 5 GHz antennas

Didnt realize all n routers did this. Checked mine and it shows my computer on 40 mhz and Nook on 20.

I checked and did not have WMM enabled on my router. Enabled and although the connection speed still says 54 mbps, I recorded much higher, sometimes double, the download speed vs WMM turned off. Thanks! It might be a fluke but the speeds were not far off my desktop.
Actually it is a fluke. All along I have been using the android app for speed test to check my nook and it shows roughly half the speed vs the regular desktop speed page of speed test. Oh well at least I know I'm getting all the speed out of it.
fyi the Wifi chip is capable of up to 65mbps. I've seen this rate from other tablets with TI WLAN chips on my router. I haven't a clue why the Nook Color won't go that high. Not on any N router I've connected to.
I even took a look at the tiwlan.ini file but I don't see anything apparent in there. N appears to be enabled.

halved Wi-f speed

So my wi-fi speed was awfully slow on my razr I, I started diggin on the settings and I managed to improve it a bit by changing the channels on the router, but still, compared to my desktop pc, and my friend Iphone 4s, I only get half the speed!! (12bmps vs 6bmps), I'm the only one with this issue? any idea how to improve it? I'm on stock 4.1.2 retail br.
I get 10/1Mbps when using my Razr (tested using "Speedtest" app) and 30/1Mbps when using my laptop. They are both connected using Wifi and are in the same location. Sadly, I can not tell you how other smartphones perform in my environment.

I've made another observation. My wlan ap shows a gross bit rate of 72 Mbit/s for my razr and of 130 Mbit/s for my laptop.
It (kind of) reflects the relative performance difference I get when comparing the devices - so maybe the Razr just has a bad antenna?

great info man, I did the channel thing and it really improved my wi-fi speed, (it wasn't even reaching 1mb) in fact, I even thought of enabling the channel 14 to avoid any interference, but, I still can't get more than 5mb on my phone :/ (vs 12mb on my pc) do you get the same speed on your router as on your laptop/pc?

I think i also never managed to get the 150 Mbit/s Mode on my Ri. I have the bad feeling that the Ri is at least capable of the "n" Standard but
didn´t get the MIMO feature of 2 discret WLAN-Antennas or it can´t manage 40Mhz bandwidth...
I will test again if i´m home...
P.S. be sure to use "WPA2 AES" only! Not WPA1+WPA2 mixed mode and not "WPA2 TKIP"!

yeah me too, but didn't found anything, except for the above and this, maybe its a bug in my router that makes the phone fall in that legacy mode, dunno.
i have a little update:
- Razr i is indeed MIMO capable (11n standard), but can only use one paralell data-stream (1T1R = 1 transmitter 1 receiver).
That means it realy can have up to 150Mbits in a 40Mhz Bandwidth network.
can only use one paralell data-stream (1T1R = 1 transmitter 1 receiver) with 20Mhz Channels = 75Mbits max.
BUT:
- The newer 11n standard not allows to manually select 40Mhz Bandwidth in a 2,4Ghz Network
(There are some older "N-Draft" router that allows manually selection of 40Mhz Bandwidth in a 2,4Ghz Network)
The newer 11n standard only allows 40Mhz in a 2,4Ghz Network in "Auto Channel Mode" together with 6 free Channels in a row.
In a 5Ghz network it is allowed to use 40Mhz manually because there are much more channels to use...
So on newer router with 2,4Ghz and 20Mhz Bandwidth network you will have max. 68Mbits brutto (= ca. 5 Megabyte/s netto).
Maybe you could get an older n-Draft router to test, or play with the 5Ghz setting?
Just check if your Router is able to set up 40Mhz Channels in a 2,4/5Ghz network...

well, my router allows me to use 40mhz in a 2,4Ghz network, but the problem remains, also it doesn't let me use the 5ghz band, still 5 m.bytes netto should be more than enough for my 10mbits internet connection, I guess I need to try on another router, or get more feedback from other users.
Can you try renaming your 5Ghz Network to an other name than the 2,4Ghz Network!?
I have something read about that this could be a problem...

Trouble with tablets on 5ghz network

Hi
I have a dual band router, and i prefer to have as many devices on 5ghz, as it performs A LOT better in my apartment.
Of course i know that the chromecast is 2.4ghz only.
I have this issue: When i start something (netflix, youtube, deezer) from a device on the 5ghz network, it starts fine, but when the tablets go to idle mode, very often they stop seeing the chromecast and i lose control of the content playing (although it is still playing). This is not an issue if i run the tablets on 2.4ghz.
Any ideas?
May have set the tablet to to only use 2.4ghz when you are using the CC. Settings are under advance I think under WiFi.
I know with my phones in the house we have to limit it to 2.4 instead of 5ghz or we don't even see the CC since the our router has 2 separate ids for 2.4 & 5

That's weird, I have my 2.4 and 5Ghz networks with different SSIDs and I can see the Chromecast from either from both my tablet and Nexus phone regardless of which frequency they're on.
Really? Hmm with our moto maxx's and both RAZR M (all unlocked and rooted running newest firmware). When we have them in only 5ghz mode we can't see the CC
Are you sure the problem is actually related to using 5 GHz? I've seen the same problem on my 2.4 GHz devices - loss of connection to the Chromecast a few minutes after starting a stream, and difficulty of re-establishing it to control the stream. Maybe something else has changed, or you're just noticing the problem now.

Mines started doing it the last few days as well on 2.4ghz only, only some apps do it, youtube been one.
it's been my experience that CC can only be seen across 5 & 2.4GHz when channel width settings match across bands.
having said that, i've resorted to isolating the 2.4 band for CC traffic only, keeping all other devices (except tablet doing the mirroring) on the 5GHz band. ever since making the change, CC streaming has been relatively flawless.
It's probably a WiFI signal reception issue in general.
Case-in-point, I also have a dual-band router with different SSIDs on 2.4 GHz and 5 GHz APs (you really should use different SSIDs except in special cases).
When my phone has strong medium to signal, I have no problem using Chromecast while connected to 5 GHz. Phone sleeps, wakes, still connected.
However, I just moved my workstation to another room where 5 GHz is weak. 2.4 GHz is still strong (lower frequencies travel better), though.
With my phone on 5 GHz, control of Chromecast was sluggish. Chromecast's playback was fine because it's still getting good 2.4 GHz signal.
My phone went to sleep, and when it woke it "forgot" it was controlling Chromecast - in fact, it could not longer see any Chromecasts.
I switched over to the 2.4 GHz network and Chromecast was visible once more. I rather use 5 GHz on my phone and leave the 2.4 GHz band uncluttered, so I might have to relocate/reorient/reconfigure my router now...
When I'm streaming and tab casting from a laptop, I connect it to 5 and everything runs smoother because the data stream is divided over two frequencies. However I find that the Nexus 5 screen casting feature is not as content to operate if I'm connected to 5 GHz.

G900-F real life WiFi 802.11ac performance benchmarks

Hi all
I couldn’t find detail benchmarks of S5 implementation of Broadcom BCM4354 2x2 MIMO 5G WiFi 802.11ac module and in the end decided to take u plunge and purchased Asus ac68u router. Went thru setting up 5G ac wireless network and current results look like this:
S5 connects to 5G ac network with link speed of 866Mbps
File copy from:
Gigabit LAN wired PC to Routers attached USB 2.0 HDD 29MBps (240Mbps) - bottleneck usb 2.0 interface
5G ac WiFI S5 internal storage to Routers attached USB 2.0 HDD 11 MBps (90Mbps)
5G ac WiFI S5 sandisk 128GB microSD card to Routers attached USB 2.0 HDD 11 MBps (90 Mbps)
I have 100/100Mbps broadband internet connection and S5 on speed test performs as follows:
72Mbps DL / 75Mbps UL (same connection via wired PC benchmarks at 94Mbps DL / 95Mbps UL)
I haven’t managed to achieve transfers speeds above 100Mbps from or to S5 in any combination. Can you please share your experience of S5 wifi ac 5G network performance
Related : thread by xenokc about S5 performance on 802.11ac network

Yes, i have tried that, but there was no change. Router firmware is upgraded to the latest version / wireless test were done in close proximity (1 meter) to the router without any physical obstacles between (clear line of sight)
I'm really on a mission to achieve transfers speed in a range of 350Mbps-400Mbs on local LAN (which should be doable) but i cannot get pas 100Mbps!!
i'll try to test as i know AC should be able to do it.

fffft said:
802.11 ac provides a theoretical maximum stream speed of 433 Mbps or 900 MB/s across eight streams. That is under ideal conditions - maximum signal strength, zero interference, zero processing overhead and zero packet overhead. Many router 802.11ac chipsets only support four streams and due to real life channel contention, you aren't likely to see more than two or three 160 Mhz channels chopping that maximum speed to about 250 MB/s. All of those speeds assume channel bonding and quite a few routers can't bond 80 Mhz channels cutting that speed in half again (125 MB/s). Then you have real world losses due to signal attenuation, antenna inefficiencies and interference.
The S5 was the first smartphone to support two MIMO streams. But two is not three, so lop another third off our speed figure (or lop two thirds off for the iPhone 6 which only supports one stream). You simply won't achieve your goal with the S5 or any other current smartphone. 350 Mbps is the upper end of the maximum speed you might expect to see from a high end MIMO PC card under ideal conditions in the same room.
In real life and through a wall, you should expect considerably slower transfers. And the type of traffic matters too e.g. TCP traffic overhead often reduces speeds three fold over UDP streams in router speed tests.

Thanks for detailed feedback, but then there is no benefit from implementing ac standard or 2 spatial streams suporrted by broadcom chipset when performance is comperable to WiFi n standard? But then again how did those guys here managed to pull of such results:
382MbpsDL
or
436Mbps
whit same hardware setup?
..
what kind of latency differences did you see between the wifi phone and your pc to the same server? i'm assuming speedtest.net or something like that?
This is strange as for my G900I I've been able to run an Internet speedtest at over 11 MBps (88mbps) over wifi on wireless N at my university which I imagine would have multiple connected devices. Wireless AC should be able to at least match the 88 mbps I had achieved.

can you test with no encryption? wep/wpa completely off.

No, don't do this. You must setup a WPA2 security encription to get maximum rates on WiFi N and AC.
Then, remove storage bottlenecks. Don't use a external HDD connected to a USB2 port. Much less on the same router, since USB performance is much lower on those devices. You will need to use 2 devices on the same LAN. One wired for maximum throughput tests. A ramdisk or a SSD on the host would help too, since HDDS are limited to 120-80Mb/s transfer speeds.
If you are going to use a file copy as measure, make sure you make it into the internal SD card of the phone, since external will be limited to around 8-12mb writes depending on the card quality.
To test networks you would need ramdisk to ramdisk copies, but I don't know how to setup this on android.
This is rather interesting to follow
iPerf is available on android.
Quick measurement gave me ~110-169 Mbits/sec using default values on 40mhz WiFi N 5ghz setup.

Thumbs up. Finding someone that uses IPERF for measuring proper network performance is golden. It irritates the heck out of me to find video's of people using ookla to measure their network speed, or like the OP, measuring against USB2. That's like measuring the speed of your new 600MB/s SSD installed on a SATA 1 controller and wondering why you are not seeing a significant improvement.
iperf is a little more complex than ookla though, and thats usually why. same reason most of us dont compile our own custom roms
really, there isn't much need to get over 100mbs on wifi for 90% of the public.

Just picked up the s5 because no store will sell me the note 4 retail price.
Linksys WRT1900ac stock firmware, 5Ghz a/c connected @ 300Mbit
From the phone to wired linux box @ 1000Mbit
187 Mbit up 207 Mbit down but of course it fluctuates. I don't use wifi for anything that requires that much bandwidth anyway, but I do get my full internet speed of 175/30 using the phone.
This post is rather old, but some of us may still be interested.
I was looking for an alternative to usb cable to transfer files fast between a pc and galaxy S5..
I've used a wifi-300 stick connected to usb port on PC: TL-wn821N, and configured my S5 as a mobile access point.
An ftp server is running on the phone and an ftp client on PC. i am accessing the AP via AirmoreAP hotspot, with wpa encryption.
I am watching the download rate via crystal internet meter for windows.
And this is the result: 64mbps/56 mbps (DL/UL) UL reading a microsd card on phone and writing to sata2 internal disk on pc.
I am wondering if I can reach much faster speed with a wifi-ac stick.

WiFi bandwidth? 5Ghz vs 2.4Ghz - how to test which is better?

After recently upgrading my family's phone's, we all now have 5 Ghz Wi-Fi capable devices, so I got a dual band AC 5 Ghz Asus router.
My broadband is rated at 20mbps down...ok, so testing with ookla speed test I'm getting the same transfer rates on either of the Wi-Fi bands (2.4 Ghz or 5Ghz)
I thought I read somewhere 5 Ghz is what you want, and should select that one....but now I'm understanding it has much less range but more bandwidth, but if I'm maxing out my 20m connection at 2.4 Ghz, what is the advantage of 5 Ghz?
(I hope this makes sense to someone who can reply)
5ghz is better if you are struggling with 2.4. Depends on how many mouths you are feeding. If you speed test near 20mb then don't worry about it cause ur not drawing a lot.
BAD ASS NOTE 4
2 things
1. Set them up as 2 separate networks with different names as passwords. Thus prevents devices from auto switching
2. As a general principal 5.0 ghz I'd better for streaming media and gaming, but does not go through walls well. 2.5 ghz is what gives your router is range. So anything that is streaming (eg. Xbox, chromecast, pc) you want on 5 ghz and close to your router, anything else you want on 2.5 ghz so it will work at longer range without losing signal.

802.11n on 2.4GHz can connect at a minimum of 72Mbps and a maximum of 600Mbps. Unless you spent a boatload on a router and live in the middle of nowhere and operate no bluetooth devices you're unlikely to get 600Mbps on 2.4GHz as it relies on having four antennae and a 40MHz block available. 5.0GHz is much less congested so you'll always get the full 40MHz channel and the speed is limited by the number of antennae on your router.
The Note 4 supports 802.11ac, which skews it more heavily in favor of the 5GHz band. 802.11ac can use up to 160MHz channels which can achieve a data rate of 1300Mbps on the 5GHz band.
Now, all of that is completely theoretical. I can tell you that my T-Mobile Cellspot allowed me to hit ~80Mbps on 2.4 and ~130Mbps on 5 when I had a 130Mbps connection. I switched to Verizon and took 50Mbps due to cost, and the router they provide will only hit 50Mbps on the 5GHz band. On 2.4GHz I see closer to 25Mbps unfortunately.
Basically, I would set it up at 5GHz and walk to the extreme end of your house. See if you can still speedtest at your full line speed. If you can, stick to 5GHz. If you lose signal, drop to 2.4GHz.
Thanks for the answers guys.
