On stock Rom under WiFi settings there's a WiFi best performance setting under advanced . Any idea of what it does other than eat away battery power?
I too am wondering this.

Wondering the same. Thanks for raising.

Raised it but still no answers LOL!
The tests using Speedtest.net seem a little smoother. As far as any real speed increase it is hardly noticeable using that particular app. I am curious as to what it does to the battery. It says it may consume more juice but I don't really see that either. Is anyone noticing faster battery reduction or any real speed increases?
I believe it allows for 5GHz 802.11n rather than using 2.4GHz
Wi-Fi best performance has nothing to do with the band. It has to do with ACK packets and WMM performance. It allows a clear and direct communication path between your phone and your router. Much like QoS in VoIP mode.
Hope this helps answer your question.

I've owned a computer company for 18 years and been in the computer field for 20. I spent years helping people with Blackberries and UMA calling. Not to mention over a decade of networking experience.
I watch every packet on my network with a packet sniffer and its functions as well as my router logs. It's just something I know.
Take it or leave it.
The Wi-Fi stack is easy to monitor as is the IP stack.

I have had the Vibrant for about a week, and love it dearly despite its shortcomings. I have noticed the data speeds and connectivity are in no way related to the amount of bars of service showing, except when it drops to EDGE (which it seems to do an seemingly random times).
I ran the Speedtest.net app about 20 times in different settings, many one right after another without holding the phone. The speeds fluctuate so wildly I can't describe it.
Sometimes I get DL speeds of 100kbs and upload speeds of over 2mbs in the same test, and everywhere in between.
The Nexus one fluctuates a little bit, but no where near this. N1 is on CM6.
This sucks because sometimes for example I'll click the news widgets story, and the webpage will not load even with full 3g service.
And yes, I can stop the speedtest completely by covering the antennae bump with my finger.
Any Ideas?
I also suffer from very spotty GPS functionality, even after the fix. I am not able to root this phone the standard way, tried over 20 times to restart holding VOL up and down, never gets to recovery mode - have not tried adb yet. (I'm at work lol)
Have you done a factory reset on the Vibrant? You should if you haven't. Might solve this too but there is something you have to understand, bandwidth is shared on every tower. If 2 phones are downloading a 1GB file EVERYONE's speed will suffer on that tower. So make sure you're not doing them at the same time because it's not going to be accurate if you are doing them at the same time
Hmm interesting, and thanks for the response. I don't think two phones downloading a file at the same time should make a huge difference, I am in downtown New York City.
I usually kill all processes on an hourly basis usually to prevent lag. Should I not?
System restore from the recovery menu you mean?
I only did two concurrent tests on the N1 and my Vibrant - all others were done by itself.

Do you recommend a backup first? Like Titanium if I was rooted?

Umm, not necessarily. We don't know how big the internet pipeline for each tower is. The way GSM works though, is each tower only has a specific number of slots for phones that can be connected at one time. Kinda lile a QOS type thing. So each phone sorta has a dedicated pipeline while it's connected. That's just on the GSM switchboard, though. As far as I know the internet pipeline is shared. I'm not saying one way or another on speeds slowing when more people are online, just saying "don't jump to conclusions". Because if they engineered the internet pipeline the same way they engineered the GSM switchboard, then each phone might have it's own dedicated pipeline. Just saying.

3G is not GSM. Bandwidth on each and EVERY tower is a shared media. I know because I've done it myself. Two phones pitted against each other would always leave one phone slower than the other.
Also there is the possibility that the phones are each on a different tower.

True, 3G is a CDMA technology but I really doubt the pipeline is so small that two phones running a test would cause it to slow down. A more likely explanation would be that the radios in the two devices were interfering with each other, and suffered a slower data speed due to lower SNR.
unrelated to this, how do you guys get your speed test results to show on your signature?

just learned that myself, for some reason my pinch to zoom was not smooth at all when loading certain websites it would be very choppy and such until I did a factory reset, now everything works perfectly. Also I think having a task killer is a must on this phone at times I can have 36 apps running at a time which makes for a laggy phone. I thought these phones had better self management systems. Guess not!

Get the image of the speedtest result then [ img] picture link [ /img] ?
To get the image: Do a speedtest.. click Direct link when its done and bam.
But most likely since its T-MOBILE USA as the ISP.. they most likely tethered and did a speedtest on speedtest.net

When you complete a test at Speedtest.net, it gives you a link to a picture of your results to post on forums and such.

Thanks for sharing.
I will say though that speedtest.net is not very accurate and very buggy. I've experienced some of the same issues as you and have been using speedtest.net for a very long time.
I'm curious to know what the most accurate speed test site is out there.
Try: www.MobileSpeedTest.com
When doing the test, let the initial test finish, but scroll down and click on 2MB test to test it again. That should give you a pretty accurate result.
so there is no way to do it from the app itself?

yes, go to the results tab then go to the specific test you want the results to. Then hit the menu button and click "email results", it will send you the same picture that the "direct link" would give you.
Came across this->http://forum.xda-developers.com/showthread.php?t=1466245 thread on the x2 forums. It cites that most 3g speed tweaks are aimed at gsm, and suggests a build.prop edit that might improve cdma 3g speeds. Before I go any further, I should say, I have no level of expertise in this, and have no knowledge of what function this line in the build.prop served before or after said modification. Now, with that out of the way. I checked the build.prop on my r800x running cm7 to find the line in question was not even in my build.prop. Perhaps for a reason however, as I said ^^^ no knowledge whatsoever in the matter. In any case, I added the line suggested to be edited and changed the value to the suggested value. From my rather breif and unscientific testing, my 3g speeds seem to be faster. Browser, xda app, twitter, and google+ just to name a few seem more responsive when requiring data to load what's being displayed. Keep in mind, my observations are strictly just that, observations. This could all be placebo.
The line is:
Code:
persist.ril.uart.flowctrl=1
Its suggested that it can be any number between 1-10. And recommends 10.
I just added it to the bottom of my build.prop. and changed 1 to 10, then rebooted
*Disclaimer: I'm not responsible for ANYTHING you do to YOUR phone*
Well, anyone else feeling adventurous? Moreover if any more knowledgeable folk know what atrocity I just committed, I'd enjoy your entertaining my ignorance with your input . I'm curious why my build.prop lacked this line. Also, I'd love to know what purpose its actually for. On that note, I'm off to Google.

I read through the entire thread of replys form the link you found, Seems this does work for some and others didnt notice.
Im def. gonna try it out later , thanks for sharing!
I'll try this later as well.
I been playin around with it now. I used the recommended 10 and didnt try any other numbers. I used the SpeedTest app and tried to do it in as much of a "controlled environment" as possible.
I first chose one spot in my office at work that id say was the best for service and I held my hand in same position for the entire test of this tweak idea. Then with tweak applied I turned the phone off , waited 30sec, turned on, waited 30sec, Opened Speedtest, made sure my server was the same each time then began speed testing. I ran each test back to back without leaving the app or shutting the screen off, There were about 5 seconds in between each test, only to write down test numbers.
I did (10) tests with and (10) tests without the tweak in build.prop
I attached my results. I highlighted the best score from each set of tests in each catagory. ( someone correct me but isn't a "lower Ping" better? )

Lower ping is better, these definitely suggest lower speeds as an outcome of the edit. Weird since I still "feel" like load times are faster. Ah the power of the mind

This won't really matter.
Unless your service provider caps speeds on the device, as opposed to on the network (e.g. T-Mobile, with 100mbs of 4g, followed by the network provider limiting your speeds) this really won't make a difference... (as seen by 216monster's results)
On the other hand, what if this number is like golf (lower is better) and deals with power input? Does switching to 10 provide better battery life?
@216 -thank you for testing out every new idea that comes along, whether it's missing your play to try to add an hdmi port out keeping up with cdma uk ROM

Hi guys.

If we let the option “WIFI frequency band” turned on Automatic, and of course if your router has both options simultaneously, would you know which band N4 will pick up? Is there a preference order?

Thank you.

What ever one you sign into as long as you have it password protected. If not password protected I believe 2.4ghz is the standard meaning that it would most likely pick up 2.4ghz. Don't quote me on that though.

I have both frequencies and my phone shows no "preference". It seems as though I get better reception on the 2.4 but I don't think that has anything to do with the phone.
Do you experience any problems with your current setting?
If not, why bothering to change that option.
If you do, try all options and test yourself (speedtest.net) & stability

No, had no problems. Only the strength on 5Ghz is weaker /shorter depending where you are in your house. Of course is because this frequency has a wider range, so it's normal.
And I have done that, I tested a lot. And I don't bother, just want to know how it works, as simple as that. Why would the phone pick up the 2.4 Ghz rather than 5Ghz? (at least it seems it does so), on the same strength conditions, considering that the quality of 5Ghz is overall better?

So I recently got this tablet, rooted it, and installed the 4.3 nightlys (this ROM: http://forum.xda-developers.com/showthread.php?t=2413878)
I've been bringing it to work so I can just get things done faster reading e-mail and news without distracting during my breaks. At some point, I started to noticed how incredibly slow things loaded up such as trying to load articles from feedly as well as its videos. I later noticed that my wifi was only 2 bars. I figured it was enough but apparently it isn't as things just load up so bloody slow.
I decided to to download the app, Speed Test, into the tablet and found out I've been downloading at crappy speeds of 900-1100 kbps while my Samsung Galaxy S4, in the same area I'm testing the speed, is running at ridiculous speeds of 26-30 >mbps<.
I actually restore the tablet back to original stock and tested again and same deal. Has anyone got this problem? I'm leading to believe its old hardware which would be incredibly disappointing if that's the case... but maybe there's an update or fix for this terrible wifi?
Check your Advanced WiFi settings - disable 'WiFi optimisation' and see how that goes. Apparently it slows things down!

you can enable/disable when you need , for example if you in need to get faster internet to download you enable, then disable after using, i found it useful on my phone.
The only notice to take into consideration, if your Wifi is very slow (some countries having limited quota for ADSL internet then drop speed to 512 Kb ) and you enable download booster, in this case will not help, you better need to disable Wifi and use only data.
