Wifi 802.11n limited to 65Mbps max?

I've stumbled across a number of postings that mentioned people get a maximum throughput of 65Mbps with the Wifi N mode on the Desire. That would make sense as it likely only utilizes 2.4GHz with limited internal antenna capabilities.
What it also means is that 802.11n is pretty pointless compared to 802.11g which already provides data rates of 54Mbps, and reportedly consumes less battery power.
It was also reported that the official Froyo release already activated 802.11n mode, which would make further modifications unnecessary.
My questions in the interest of throwing anything related to 802.11n out of the ROM:
1) does Froyo indeed include N support? (I don't have a N router and can not test it)
2) is N indeed limited to a max data rate of only 65 Mbps on the Desire?
Thanks for reading and hopefully feedback

I have an 802.11n router and gets a max of only 65 mbps transfer rate using Froyo. I have since disabled N support on my Desire to save some batt life.

Using Pays Froyo 1.9 with enabled N and connecting up to 72Mb/s.

Not sure about anyone else, but with 802.11g the phone will connect at roughly half signal to my router, speeds of about 20-25mbps, when i connect via 802.11n the signal is much better and it connect at full 65mbps, though yeah i never get above 65mbps, i think this has to do with the antenna arangement, 802.11n had 3 antennas, and i think the desire only has 1 so the total speed is limited

i´m more interrested in the speed you transfer with on the diffrent modes since i get less than 20Mbit with G from local to local.. and i wonder if i sould invest in N ? does it give higher transferrates ? eg the speed of the filetransfer between comps..

sorry to ask
sorry to ask a noob question, but where again do you check to see the speed of your wireless, I did it once but can't remember how.

Phone *#*#4636#*#*. As to higher WiFi N speeds. We won't get higher speeds that 65-72Mbps because WiFi N mostly operates on the 5GHz band.

How did you disable N support on the Desire?

what a brainfuck 802.11 works with up to 600mbps at 2.4 ghz like on 5 ghz
. i wrote exams about wifi.
i bet the desire uses 1 antenna so it can get a max of 150mbps symbol rate.
but i think it uses a channel bandwidth of 20 mhz instead of 40 mhz so it is limited to the half of 150!!!

Well im currently connected at 72 using LeeDroid

ye this just shows your connected speed..
to get the actual speed you need to transfer a file between computers locally.
those 2 speeds vary alot since it depends on noise and interferrence and loss.

OK, that explains it. So we have a physical limit here for the throughput.
How about the better signal strength for N? This may be the result of the coding scheme. And more importantly, does the stock Froyo already provide 802.11n, so we could get rid of all the firmware and module hacks?

Bongmaster is right, you have different speeds for wireless N devices.
The desire is 1T1R (1 transmitter 1 receiver), and therefore can only only get 150mbps as a max theoretical speed. 2T2R is required for 300mbps operation.
However as mentioned, this only works with 40mhz channel bandwidth, 20mhz will cut it in half again.
Can someone force 40mhz channel bandwidth on their router and post results? Most Wireless N routers seem to come with 20mhz as the default setting.

Let me bump this again, there is one important question that was not answered yet:
Does the stock Froyo release (OTA) support Wifi 802.11n or not? I can not test it as I don't have access to a N router.
Thanks!

Everything I have read says yes.

I did this and it made no difference, 72Mbps was the maximum it showed.
To be honest, I'm not sure the Desire is even capable of handling anywhere near this speed anyway. When connected to my home wireless at this speed, the actually download speed I get via speedtest.net is somewhere around 15-20Mbps and I have a 50Mbit connection.

Don't know what's up with all yours but mine is running at 425.9 MBPS.. IT is lightening fast, much faster than my 128mbps stick.

That's all your getting from your ISP then when you tested, try it again at 2am or something when there's less people in your area sharing your bandwidth.

[Q] Fastest Link Speed you've seen over Wi-fi?

Forgetting all external speeds, what is the best link speed you've seen? I can't seem to get over 65Mbps on the GNex. I've got a 300Mbps 5gHz router that I am connected to and it will never connect at over 65Mbps.
Has anyone gotten higher? Yes, I know that is faster than most internet speeds but I'm interested in certain streaming at home and I'd like to get the best connection possible.

I'm connected at 65mbit too, it is N speed since regular wireless is 54mbit though. I haven't seen any specs other then it supports N networks.

And you need more than 65mbps why?

I bet the hardware is limited around that speed of 65Mbps...mobile cpu/ram is bottleneck.

Yup 65mbps is the max connection you will get - same as the iPad 2
Cant be bothered digging up details on why, because it wont change anything

Same here but with a net connection of 20Mbps then I don't think I'd often benefit from faster. Usually do file tranfers over wires as well

Effective wifi speed

Hello,
as you know Z2 Play support 802.11n protocol and not ac.
I'm wondering what is the maximum speed it can reach, using a 5 Ghz band.
Has anyone done a test or something near with a fast connection like Gigabit Fiber Internet?

Ok guys, I've done some test and those are the results: I've tested today the effective wifi speed at 5 Ghz, and the maximum that our Moto z2 can reach is 110 mbps.
Which is lower than the maximum of the n standard (150 mbps).
WiFi speed of the network is around 240 mbps, tested with a smartphone wifi ac support.
Hope this could help.

i'd tell you if i could connect to a 5ghz router....just bought one of these and wifi is sketchy (drops and won't even connect to 5ghz).
any thoughts?

I have the gig internet at home from EPB here in Chattanooga, TN. Most of my devices will run between 240-350 Mbps on 5g wifi. My Moto z2 Play will run around 110 Mbps on a great day. The best it's ever had is 114 and that was only 1 time. My 4k Firesticks average 250, even on our patio. The signal on the Moto z2 Play is definitely weak.

Fastest WiFi speed?

Hello,
I have just switched fiber provider at my place (FTTH) and I am now getting a whopping 1000 Mbps on my connection via gigabit ethernet.
My ISPs internet "box" luckily comes with 4 gigabit ports but only 2.4 Ghz WiFi (...). Which means that what actually reaches my portable devices is somewhere between 20 to 70 mbps, depending on my location in the house.
So, I ordered a Netgear R6220 to connect to my ISPs box, whose WiFi I will disable, hoping to get the most out of my fiber connection.
I see that this router supports simultenous Dual Band (300 + 867) which should exceed my ISPs downstream bitrate. But I wonder whether the 835 on my P2XL will be able to benefit from the simultaneous Dual Band transmission.
According to the specs it should (https://www.qualcomm.com/products/snapdragon-835-mobile-platform):
Wi-Fi
Wi-Fi Standards: 802.11ad, 802.11ac Wave 2, 802.11a/b/g, 802.11n
Wi-Fi Spectral Bands: 2.4 GHz, 5 GHz, 60 GHz
Peak speed: 867 Mbps
Channel Utilization: 20/40/80 MHz
MIMO Configuration: 2x2 (2-stream)
Peak QAM: 256 QAM
Wi-Fi Features: MU-MIMO, Multi-gigabit Wi-Fi, Dual-band simultaneous (DBS), Integrated baseband

But since the Peak speed is listed as 867 mbps, I'm not sure...
Anyone was ever able to max out the P2XLs WiFi speed?
Thanks!

This is mine today, I have seen higher from my wifi but this is right now.

This is the best speed i got using the 2XL
1Gbit line using a Asus RT-AX88U router.

Wow, this is impressive! I didn't think our Pixels could reach that level of performance!
I guess that the bottleneck for me will still be on the router, then, since I'm not getting anything quite like yours (smaller budget).
I'm getting from Amazon an R6220 and a couple of Tp Links (archer c7 - 1750 and archer c1200), the best one gets to stay! ?

You should be able to reach decent speeds with any of those routers the only reason I bought this one is so i don't need to buy another rooter any time soon.

There you can find fast access point for low price with high quality, I use only these

A70 wifi network speed

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 .
you guys found any solution ?

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.
