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.

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.
I thought I read somewhere that wireless N uses less battery??
Now the epic does not have a 5mhz radio...
So if I go buy a 2.4mhz wireless n router, will I see better battery life?

Wireless N is more efficient than A B G. But your still having to transfer a lot of data, so I it all depends on how much you use it really. If you mean compared to using 3g then yes it will use less battery.

Will i see an improvment in battery with 802.11n over 802.11g?

Mhm, you'll see an increase in speeds since 802.11n is able to handle more bandwith than 802.11g
And yeah you'll have better battery since its more efficient

Not sure how this will be more efficient if your still running in the same spectrum? The whole point in wireless N is to run in a different spectrum then A B G. 2.4 is full and fragmented unless you have a N capable device it is still going to be in the full and fragmented 2.4 spectrum sorry just doesn't compute for me. If your saying a N router will handle 2.4 better not to sure about that. Unless the Epic is N capable and if that is the case I will be going out to buy a new router
Just my 7 cents worth! Sorry use to be 2 cents but inflation you know.
I have wireless n. On eclair I would see massive difference in using wifi over 3g as far as battery but not on froyo they are about the same now. But speed wise the n is way faster and has really good range too.

From my limited knowledge and experience, it really depends on signal strength. Let's pose an example.
Assume one's 3G signal is 1 bar out of 5, while their 802.11g (Wifi) signal is 5 bars out of 5. Running on Wifi will lead to much greater battery life than on 3G because your connection will be much stronger, i.e. less chance of dropped signal, blah blah, etc.
Now, assume one's 802.11g (Wifi) signal is now 1 bar out of 5, while their 3G signal is 5 bars out of 5. This is iffy territory, but generally one can safely imagine that running on 3G will yield better battery life, simply because the phone is still going to have to work pretty hard to maintain a constant Wifi signal.
Now, move into the realm of 802.11g vs 802.11n. Assume signal strength for both will be equal, either 1 bar out of 5, 2 bars out of 5, 3 bars out of 5, etc. The difference between each signal is efficiency and speed. The faster one can transfer the same amount of data, the less amount of time the phone has to remain in a state of high CPU frequency and heavy load. Furthermore, 802.11n (Wireless-N) is known to have a higher efficiency than 802.11g (Wireless-G), so battery should be saved there, too.
Still, I think it's also safe to say that the difference between a Wireless-G router and Wireless-N router will be about equal in terms of battery life. Maybe you'll get another 15 minutes of battery if you upgrade to Wireless-N. MAYBE. And that's assuming you transfer or download large files on your phone, or listen to lots of Pandora where you're constantly using data. Is it worth it? Will you actually notice that in the real world? Is that assumption even applicable to how you use your phone?
tl;dr - Unless the Wireless-N router's greater range over the Wireless-G router will get you more bars when connected to Wifi on your phone, the difference is likely negligible.
Thanks for the info!!!
Ok so I gather that I won't see a big increase in battery, by buyn a new N router, but I stil might just to add one to my network for stronger signal...
Now I have a large house, 3500sf. I have 3 routers (fios router, one in media closet, one in back side of house) why won't my epic drop the weak wifi, and connect to stronger one? Won't this help battery life?
Also is there a wifi preference order (prefred wifi connection), like on windows?
Right now my routers are just set as access points (not gateways), so my fios router is my dhcp for all wireless routers on the same subnet... currently each router has a different ssid....
Should I set all ssid as the same name, can this help? Or will it just confuse my phone?
Thanks again,
Nathan

2 things you may want to research 1 put your router in the center of your house then range issues are gone. If you cannot put it in the center then look at making the other routers a wireless repeater of the first. Which means they would all put out the same ssid and all be the same wifi connection just repeated from the first router just stronger cuz the 2nd and 3rd routers are transmitting and recieiving data. Now I'm gonna throw in a 3rd option go buy a cisco wireless access point that will have your wifi covered for a qtr mile and has connection speeds of 110mbps rather than 50mbps but that wireless access point is $750
If I do bey an expencive router that has a high output radio, will I have a problem with the router receiving the data packets from my low output epic radio?

Just ran a speedtest off my dualband 150mbps router.
on pc i average: 9 ping, 30.5 mb download and 3.5 upload
on phone just got: 29 ping, 13.5mb, and 3.5 upload
So it's not going to be as fast as your connection if you have a good connection, but if it's a slower connection(10m or so), you oughta be fine.
You have amazing speeds haha.
I get about 11mbps dl 4mbps ul

And about 14mbps dl and 4mbps ul

I have a 15 meg connection, and when I upgraded my router from g to n, I went from getting about 8 meg on the phone to about 12. My new router is a dual band, so that helps too. I live in a crowded wireless area, so channel selection is everything. Luckly there are android apps to help with that. I can't really say if it made much difference in battery life since I change roms too much, but its definately better than the weak 3g signal in my apartment.
P.s. if you're upgrading your router, look at the buffalo wzr-hp-g300nh. Its got dd-wrt, is high powered, and has tons more ram and cpu than anything under $100.

Strange, but my friend has 50Mbit broadband. I did a Speedtest.net on his computer and got 35Mbps as a result. I did the same speedtest on my phone via wifi and it couldn't get past 10mbps (1MB/s) Which is strange as Wireless G is 54MBps, and there were no other devices connected Wirelessly.
Speedtest does not measure speed of your wifi LAN. 54Mbps is max wifi local speed, not the speed at which internet data is actually transferred. So speedtest.net must not show 54Mbps.
Sent from my HTC Desire using XDA App
Phones are slower than computers while processing the received internet data. That would have caused it to show less speed. IMO 10Mbps is still pretty good for a mobile device with network of 802.11g class.
Sent from my HTC Desire using XDA App
Phone's are not slower at processing the data from the internet, that's just stupid. It's a simple measurement of speed. And I wasn't measuring the LAN speed, I wanted to measure the speed the phone got via Wi-Fi when connected to a 50Mbit source. The speed hits a virtual roof at 1MB/s and backs off. As in the speed leaps from 0kbs to 800kbs in seconds and works up to 1024kbs the drops back to around 800kbs and slowly works back to 1000kbs but the test ends before this happens and the speed is registered as around 8Mbit.
Even when uploading using Wi-Fi File Explorer the max rate attainable is 10Mbit (1MB/s) even if the network is Wireless G (54Mbps) or Wireless N (150Mbps). Now this is a running a Sensation ROM (RCMix S v2.0) which has updated the Wi-Fi to Wireless N.
Now, my point is, 10Mbps is a good speed, you're not wrong, but why place a Wireless G card into the phone if it will only ever see Wireless B speeds? It wastes radio frequency by being on the 2.4 GHz range when it won't fully utilise all of that. Just seems daft to me. I'm sure a tablet connected to a 50Mbit source would receive closer than my Desire.
I have some CCNA certifications under my belt, so I'm adept at networking, I just thought either my phone was a problem or it was a design. Like you say, 10Mbit isn't to be sniffed at.
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
Is it normal for the HTC Wildfire S to have slow data speeds or could it be because of my area? I rarely get speeds much above 2Mbps. The data speed I get on 3 UK is around 1.4Mbps average and the connection keeps dropping. I get almost full signal so that shouldn't be the cause. The speed often goes really slow at peak times. Does anyone else have speeds this slow or are they much faster?

I have the Network Mode on WCDMA only. I get slow download speeds most of the time even though it's showing the H symbol and doesn't matter what network I use. Is there a trick for getting faster data speeds by editing the build.prop file or something?
In many areas Three doesn't provide a GSM service, and in others it is out-sourced to Orange's network. Even though you may be connected to their HSDPA (WCDMA) service the speed is entirely dependant on the signal level. The speed is also dependant on the time of day, obviously the network is going to be more congested during peak times.
I usually get a download speed of around 350kB/s (2.8Mbps).
To be honest your speed doesn't sound that bad, and if you want a much faster experience you're going to have to get a phone that supports HSPA+.
The speeds I now get are always absolutely rubbish. I nearly always get below 0.5Mbps on Orange. 3 aren't much better. Below 1Mbps most of the time.
