Working Wireless N / Fm radio!

check this out over at phandroid..
//phandroid.com/2010/04/22/wireless-n-on-the-nexus-one-could-it-be/

Looks like wifi n is working and fm radio coming so with 2.2..

Uh, I already connect via 802.11n to my home router, as confirmed in my router logs that shows that my chumby is connecting at 802.11g and my laptop and phone are connecting at 802.11n.
It might not be getting 'n' speeds, but it certainly appears to be connecting that way.
I have the '850' (AT&T) version of the phone, f/w 2.1-update1 build epe54b, bought about a month ago.
Am I stating the obvious?

I have a wireless n and my nexus connects as well as having N speeds. I get about 6MBs d/l.

I have screenshots connecting to an N-only router at 65mbit and I've connected at 84mbit other times. So yeah, I'm confused.

Mine connects at N speeds (or at least identifies as 72Mbps) and using iperf to measure I can get 34Mbits/sec, though my access points have N they only have a 100Mbit LAN connection on them. For a connection that negotiates at 72Mbits/sec I think getting almost 50% of that in actual speed is pretty good. However, you will note that, 34Mbits/sec is well within reason for wireless G.

to be honest i didnt even realize that until after I looked into it. I guess its good news for the stock guys..So anyone heard anything new with the fm tuner?

Didn't we already figure the 802.11n part of this out?
As I recall, the N1 was initially advertised as being N compatible. Then Google took that off the site. I think it's assumed that it's able to connect to 2.4Ghz networks, but not 5Ghz networks. So, it connects to some 802.11n networks, but not all. There's some kind of speed penalty for being unable to use the 5GHz portion of the spec, AFAIK.
Hope someone corrects me if I'm wrong.

It said "802.11 b/g/n" on googles page when I bought it. It gave me the "go ahead" reason to buy an N router.
It just says 802.11 b/g now though...as already stated.

Who really cares? Wireless G is not going to be a bottleneck connecting to the internet, and I don't know if we can move data onto the microsd card all that fast anyway.

So with the new driver adding FM support does that mean we'll still have to wait for 2.2 or can people start getting it working now?

Not unless you can compile it...
Unless kmobs or cyanogen has released a compiled version that they were playing with last night?

this is no problem to compile with a standart (included) make script. But ! It will be executable file (if you want i can post him). It works (runs) but i dont know now what to do with him =).
Can anybody post here manual for this controller? First of all i want to try FM transmitter.
Late i will post executeble, and .so file (try to think about compile .ko module)
Sorry for my english =).

where is the last driver?
on git I only see the driver from October 2009..

nice
The ability to connect to N is great but what I really want is the FM transmitter!

I can see nothing in the driver suggesting FM support... I'd imagine that the FM support would fall into either a separate driver or perhaps the Bluetooth driver for that chip (as it operates through that part of the chip and shares audio inputs/outputs with the Bluetooth). Aaaannnnd I can't see if or where an open source Bluetooth driver for this chip is. We'll have to wait for the Desire kernel source.

Wireless N is working perfectly with my N1 and laptop. I have my router on N only and the phone is connected at 65mbps. I get download speeds of upto 9Mbps, which is max for my internet. When I was on G only I would usually get around 2-6Mbps from the N1. So the wireless N mode is more stable and consistent.

+1 on the FM transmitter.
For vehicles without bluetooth and for those who do not want an extra wire.

SQUEAL!
FM receiver, can't wait....

[Q] Focus doesnt find wireless-n network!!

On the specs it says the phone supports wireless n (802.11n), but when i go to settings and search for networks it wont show my local wireless n network, is it the phone or just wp7 that currently doesn't support wireless n?!

No problem with wireless N here. But WP7 doesn't support hidden networks. Make sure your wireless network is visible. Also not clear is whether or not the phone can connect to 5GHz band.

This is one of those unusual known software issues. The phone is capable of n, but the mediocre wifi software/interface the the phone is packaged with has no options to enable it. This is set to be a first round fix. Chalk this up there with the no hidden SSID's support right now.
There is no good reason as to why your phone cannot do this now and you probably could go into the diagnosis panel and figure it out, but that is not the users responsibility.
MS must have a great reason, but it is not readily apparent.

Yeah my router does 2.4ghz G & N plus 5ghz N; so it connects but it would be nice to know what it is connecting at. I am sure it doesn't do 5ghz because that ssid is not found as an option but it would be nice to know it is connecting to the N 2.4 and not the G.

It doesn't support 5ghz N. I had to change my router back to 2.4.

Or you can just let it connect to 2.4 11g instead. There is no benefit for it to be in 11n other than burn your battery faster.

My router is set on 5ghz wireless n, so i guess that's why the phone cant show the ssid.

[Q] 802.11a and FM transmitter

Hello all!
Here in Germany the phone is said (in a product flyer from Samsung) to be able to handle 802.11a; i have a 802.11a/b/g/n mixed network in my home and somehow the tab won't work on 5GHz. Is there any limitations or is it just a setting-thing or is the tab not intended to use 5GHz? Maybe the chip is able to work with it but they could'nt fit an antenna inside...
Also i am asking myself if there's any progress with FM reciever/transmitter usage?
The Boradcomm chip used in the tab should be capable of FM; i read a bit about it here and i know there is development in that direction. But when i open a new thread anyway i wanted to ask if there's any news on that already ;
Thanks!
Steve.

I can confirm that both T-mobile and AT&T Galaxy Tabs work very well on my 802.11n at 5.7GHz.
I've found it accidentally after running one of the WiFi scanners. Most likely yours will works as well.
Cheers!

Thanks for your reply. 5.7GHz is the highest channel we are allowed to use here.
As of now i was not able to find out how to tell the tab to use 5GHz. When i check my router it's always on 2.4 (i802.11n). Also i did not yet find a wifi scanner app that makes detailled scanning possible; maybe you can tell me which one you used!
Thanks!
Steve.

"WiFi Analyzer" works a treat.

Hi Steve,
Is your router dual band: 2.4 or 5.7, or simultaneous dual band: 2.4 and 5.7, if it's a dual band router you would need to switch the router manually to the 5.7 radio?
With my router (Netgear WNDR3700) I have two separate SSID, one for 2.4 and one for 5.7, both show when wifi scanning although I use 2.4 as it has better wall/floor penetration.

Ahoy!
I have three DIR-825 which use simultaneous dual band. I configured both SSIDs of each unit to have the same name (story of the house).
I wanted to tweak that, anyway. I will try giving seperate names.
Thanks for the hint!
Steve.

OK, WIFI Analyzer showed that i was not connected to the 5 jiggahertz network.
I now gave one BSSID to all .a peers and another to all .bgn peers.
Works.
Seems like when BSSID is same the tab prefers the not-802.11a peer.
Thanks!
Steve.

wifi bands

Does the Nexus 4 have all the wifi bands... 802.11abgn or just the 802.11bgn?
I couldnt find an answer to this.
Hopefully someone who hasbhe device and also uses the a-band can chime in...
Thanks

It is abgn

Thanks mate.
It comes to me as a surprise because Google doesn't list 802.11a support for the Nexus 4 on the Play store specs.
Is 802.11a not officially supported by android? I ask because even in my Galaxy Nexus (and this is just couple a days ago with full wipe and installing 4.2.1 from the stock rom via adb), i initially tried to connect via my 5Ghz network but it just wouldn't connect for the life of me. 2.4Ghz worked like a champ.
EDIT: I should note that the problem with the 5Ghz band is only upon initial starts. If I disable and re-enable wife, 5Ghz works just fine, but I simply don't get why it fails on the first try.

802.11n also uses the 5Ghz band, or do you honestly mean 802.11a, that most ancient of wireless standards?

yes 802.11n "can" potentially use the 5Ghz "a" band if the 5Ghz "a" band is supported.
802.11n standard was designed to implement speed rates upto 450mbps (depending on the number of channels being bonded)
802.11n doesn't simply imply that it can use the 5ghz and 2.4ghz bands. it has to state that its 802.11abgn for me to be able to do "n"-speeds over 2.4ghz or 5ghz
google play store's specs show 802.11bgn which implies its only 2.4ghz.
if its 802.11abgn, then it works for me because i use the 5ghz exclusively to avoid the noise of all the 2.4ghz channels around me and theres a ton of them

Samsung Galaxy A20 5ghz Wifi not working.

To be clear off the bad, its not the router. Every other device in the house that connects to the 5ghz band works flawlessly. This is a brand new international phone being use with AT&T in the US, calls and texts function fine. Phone is fully updated and so is the router.
Wifi however is only picks up 2.4ghz bands. Not 5ghz.
Wifi analyzers pick up 2.4ghz but when switching to 5ghz I get a messages stating my phone does not support 5ghz. Anyone else with this issue?

@aq3e No. It doesn't have 5GHz.
2.4GHz has better penetration through walls anyway.
5GHz is really only good if you're in the same room.

I also dont have 5ghz and dont have the advacned wifi option to change bands... Why this model suck this much? Probably a OS stupid limitation...

The A20 does support dual band, but it's disabled. I tried to enable it by replacing the mx140_wlan.hcf file located at /vendor/etc/wifi/ with the one from the A30 and it worked, but there's a problem.
For some reason the signal range is terrible, to detect a 5 GHz network the phone needs to be next to the router, if it gets some centimeters away the signal drops at the point where the network is not detected anymore.

5ghz wifi is certainly not only good in the same room, check online heatmaps of 2.4 vs 5ghz to compare, it's not a huge difference. Given how much less interference you will get on the 5ghz it often works a lot better than 2.4ghz even at longer ranges. Fix peoples internet for a living and I've seen thousands of peoples speeds double or even triple from changing to 5ghz even when router is on the first floor and they use it on the second.

It shows that 5ghz suffers from greater attenuation rates than 2.4

(I know this doesn't help much with the OP's question but to dispel hearsay I felt it needed to be said.)
I know you don't know me, but I said I resolve peoples internet problems for a living both on supplier and consumer side and have tested this with thousands of customers but you trust a random article with very little info more and don't even bother to look at heat maps? This article has been made by someone who read a blurb about wifi, but they did get one thing right...
"A lot of electronic devices and appliances use the 2.4 GHz frequency, including microwaves, baby monitors, and garage door openers. If you have many of these in your home, or if you live in apartments or condos surrounded by other people, that 2.4 GHz band is likely to be congested, which can damage speed and signal quality."
That list is very short, it also includes lots of computer peripherals, security cameras, smart home devices, walkie talkies, radios, remote controls, wireless handsets (landlines, not mobiles) basically every wireless device you can think of uses 2.4ghz and even your microwave! all these devices on a long range signal means your neighbours devices also overlap to combine together to make the 2.4ghz band for most consumers a disaster for anything requiring more than slow speeds. This goes without even mentioning that the 2.4 ghz band only has 13 channels (3 none overlapping) to spread every wifi device out on to stop interference, in most residential are this is simply not enough. In many cases this is so bad that even next to the router people can lose 80 - 90% of their speeds or have so much interference that even loading webpages takes a long time due to the amount of data being lost.
Like I said before, even if the 5ghz DOES have shorter range, it is not so short that you have to be in the same room, what would be the point? That is a something people assume because it's a "shorter range signal" but it's not that short! the 5ghz is usually faster due to it's naturally higher data rates and more consistent due to the lack of interference from intermittent signals. Most things that interfere with 5ghz are constant and therefore it's much easier to test and know what speed you can get in other rooms away from the router, unlike the 2.4 which has the same issues with passing through anything only with a load of other issues on top too!. The 5ghz also has the advantage of having over 100 wifi channels to spread networks out on to avoid them interfering with each other, a vast upgrade to the 2.4ghz.
Here is an example of a heatmap comparing 2.4 and 5ghz but just looking at any article that goes beyond a very brief description will show you why the 2.4ghz is often so much worse than the 5ghz.
What's the Difference Between 2.4 and 5 GHz WiFi?
What do these numbers actually mean? Does it realy matter? Is one better than the other? How many questions are we going to ask in this description?
socialwifi.com
2ldr - It depends on your house and nearby networks, test both bands with different devices in different rooms and compare speeds, outside of doing more thorough testing with other apps and equipment this is the easiest and quickest way to see which will work better.

You have 2 choises use BT modem BT modem Plan A: one Device in 5GHz network one device sharing Internet from BT modem feature. +Advance use Open Garden mesh client for better Internet throught BT modem. Construction of my plan:One or two devices in 5GHz WiFi network and 3 devices creating PAN network trought Bluetooth.if Your Bluetooth version is 5.0 you can use Mesh network profile. than using Mesh network structure. Mesh Bluetooth network structure helping one device to other. but you need to know you will use 2.4GHz trought BT modem and Mesh networks.

No luck. I still have the signal issue

Do it again in the following order maybe ?
1. Download both mx140_wlan.hcf and mx140.bin from the git I gave you above.
2. Turn your wifi off.
3. Reach /vendor/etc/wifi folder using your favorite file browser ( Mine is Mixplorer ).
4. Overwrite both files.
5. Reboot your device.
6. Turn Wifi back on.
7. Do a Wifi speed test ( Wi-Fi Sweetspots app for me ).

I use a Magisk Module instead of directly overwriting the files, but this should make no difference. I believe it may be a hardware difference between our devices. On the schematics the 5GHz antenna seems to be marked as optional, maybe that has something to do.
I tried to put my device next to the router, and when I did it the network got detected (with bad signal tough), I could connect and the download speed oscillated between ~50-200 mbps (my network has 300 mbps). Once I moved further from it, the WiFi disconnected as the signal was lost.
