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?

lol personally now i don't my links is 17mbit but i like the 300mbps for video streaming and file transfers, if only i had an access point with a gigabit lan interface haha
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.

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
Thanks

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

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.

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.

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.
Hi everyone,
I have a problem with my new P30 Pro. When I create a Hotspot in 5ghz frequency, no other device can find that Hotspot. If I change frequency to 2.4ghz then other devices can connect to the network. Maybe others have the same problem? Or my device is faulty ?
BTW when I'm connecting to Wi-Fi, either 2.4 or 5ghz, everything works fine
Maybe it uses a channel, that your other devices do not see. I think different regions use different wifi channel ranges. Maybe you find an option for that somewhere in advanced wifi settings.
I just tried on mine. My laptop pics up the hotspot on the P30 Pro no matter if it's 5 or 2.4GHz, no problem.

I didn't find any advanced settings regarding channel ranges / regions.
BTW my phone is C431 if it's good or not, I don't know. I remember C432 used to be the best region code, if you could say so. My P20 pro is C432.
How the problem started, I bought P30 Pro, opened phone clone app, I wanted to transfer data wirelessly from one phone to another. But devices didn't connect, tried multiple times. After that I started experimenting with 2.4 ghz or 5ghz Hotspot. And found out that other devices can't find 5ghz frequency.

My laptop sees 5ghz Hotspot, but can't connect to it. P20 Pro, honor 8, nexus 6P can't even see that. Samsung S10 can connect to 5ghz. It's very strange
EMUI 9.1.0.153 resolved the issue
Nope, it didn't. I'm still having problems - my notebook can see the hotspot, and can connect to it, but the phone just won't share the internet connection.
Bluetooth is turned on, and bluetooth tethering as well, 2.4 or 5 GHz.
I tried USB tethering. Tried apps from the store. Always the same thing - notebook can see the hotspot, but internet is not working. Any ideas? The notebook is Asus Rog G751. I'm on 9.1.0.1.178.
Same here. Laptop works on home 5ghz, but wont even see p30 pro 5ghz, its strange
Worst part is, 3 months ago it was working. Since I don't use it except when travelling, I have no idea what could have changed in the mean time.
In my case, max user connections was limited.
- press "Show advanced options"
- press "Max connections allowed"
- increase the value

Hi guys,
what network cards are your PC using?
Mine has a Killer Wireless 1535 built in and I can confirm this problem:
P30 (pro) switched to 5 GHz hotspot mode and PC cannot find it.
I think I may have found a reason for it, which needs to be resolved by a manufacturer (Huawei or a network adapter manufacturer - no idea if only Killer is affected):
The Huawei P30 (pro and normal model) seems to default the broadcast channel to channel #149 (5.745 MHz) when switched to 5 GHz hotspot mode.
This is a DFS channel in the only recently approved new upper channel range.
Apparently the killer 1535 cannot or cannot use these channels yet.
Actually it won't see it first. Then, when changing connection mode in the adapter property, it is found.
But after inserting the ssid password, access is not allowed and ssid vanishes from list.
Just like a restriction to invalid channels.
The broadcast on 5 GHz itself works, which I proved with another P30 which can access the AP of the first one.
However my notebooks (all using Killer Wireless cards) as well as a Samsung tablet can't.
So resolution could be:
1. Killer adapts its drivers or
2. Huawei defaults to a 5 GHz broadcast channel in lower, more common, 5 GHz band between ch7 and ch60 e. g.
(Or adds a user-accessible menue allowing selection of broadcast channel.)
My brand new Realme X2 Pro is not detecting my 5Ghz wifi routers. I tried with another realme model also and that also doesn't detects this 5Ghz Wifi router. I tried searching with various other brands phones like Apple, OnePlus and Redmi which shows up my 5Ghz router without any issues. Seems like it's a software problem. Please look into the issue very seriously as many industrial Wifi Routers work in this 5Ghz band.
You are on custom ROM or on realme UI ? What channel your router set to. Which country you use your phone . When I am on custom ROM I can not see routers that have channel over 64 but on realme UI I can .
No problems here and I'm only connected to my 5ghz band,
On EU model with latest RUI update
i hava same issue with you. And i fix it with this severals way:
1. Turn on air plane mode
2. change your phone region to Singapore
3. restart your phone
4. then try to connect to 5Ghz wifi
