Wi-Fi Supported Speeds

I've tried multiple ROM's on my Fuze and they all seem to give me a high Tx rate of 54Mbps but a low Rx rate of only 1Mbps. Has anyone else seen this behavior or have any ideas why I'm seeing this? I thought that Raphael had full support for WiFi at "g" speeds. This happens irrespective of "power save mode" setting. My network wireless router is configured to support both "g" and "b" speeds so not sure what's happening.
Thanks in advance.

I'm pretty sure 54Mbps is the top end of "G" speeds, not sure what you're asking?

Receive rate is what he is talking about 1Mb is what I see with various roms and settings for the wifi power, too.

the device connect as g
and can recieve 54Mbit/sec
but the cpu cant keep up with the wifi interface
same deal with fast sd cards really

It's never above 1Mb rx.
Funny that the radio can keep up with 4Mb downloads over H though.

Yes, the 1Mbps is what I was concerned about. Still not sure I'm fully understanding why the connection speed is limited. If the cpu is too slow, then the network interface should be able to leverage flow control or even error correction in TCP/IP stack to prevent data overflow conditions.
Does anyone know if other similar hardware (Diamond, Quartz) has the same limitations? Maybe we can improve network connection speeds with a different driver?
Andrew

Yes i have noticed the 1mbps rx speed also. When i connect it shows 10mpbs rx for a moment and then it drops at 1mbps. Copying files over resco 2008 is around 30kb per second and that is too slow, maybe is there some registry hack for this?

I will agree that wifi speeds aren't even all that great. Maybe we need to turn data off? I'll run a test here in a bit.

I hopped on another network that is UNENCRYPTED. It bounces from 1-12Mbs RX, but they are a weak signal.
My stuff is encrypted, so maybe that is the difference?
They are also on ch 1, I use ch 10.

Encryption is pretty processor intensive unless you have a hardware accelerator. Unfortunately I do not believe that is an option.

I will say that the iphone on the same encryption settings does things fast over wifi here. Is there a comparison between the cpus?
I'll have to have my friend with the tilt connect and do a speed test.

Yes, I've noticed that the speed seems slow when on wi-fi too and that's why I started looking into this issue. My last phone was a Treo 750 so didn't have wi-fi and I really don't know how the Tilt performed in this area. Having said that removing encryption on my wireless network is simply not an option . . .
Andrew

I agree, I would not recommend disabling encryption. You could disable it temporarily for a quick test to see if it makes a big difference. If it does, then you could try another type of encryption.

i've got tp wwe rom and same issue. wi-fi has speed problems. try streaming some xvid, it can't keep it up

I can't believe more ppl aren't kicking and screaming about this issue. I have the same issue, my RX is almost always 1mb. Also you can barely stream video or even complete a VoIP call over wifi. Doesn't make sense that it would be faster over 3G than over wifi..what gives?

Edge Data Improvement for AT&T Users

There might not be many of us out there, but for those of us using unlocked and rooted mytouch on the ATT network I've found after some research a way to almost double my Edge speed. This information has been posted before in various pieces on various sites but not directly related to ATT/Edge only. Ive tested this on cyanogen 5.0.8 built will include instructions here that you can give this a shot depending on your rom. Prior to this tweak I ran three download tests, 63/38 84/41 81/41. After, I got 191/102, 133/114, 123/95.
Note that it seems that for me the speed increase takes about 10 seconds to kick in from sleep once the data connection is active.
Under the system directory, look for three files. Open each file and find a section called #GPRS class or #RIL settings. When you find the file containing this, this is the file to edit. Below I'm using system.prop. Also, when editing, do not use notepad or wordpad, I personally use EditPad Lite.
using the android sdk, and connecting your phone to pc ->
adb pull /system/build.prop build.prop
open build.prop with a unix compatible text editor
Change the following sections below:
# Default network type.
# 0 => WCDMA preferred.
ro.telephony.default_network=1
# RIL settings
ro.ril.gprsclass=32
ro.ril.hsxpa=0
ro.ril.hep=1
ro.ril.enable.dtm=1
eliminate all other lines that start with ro.ril if they exist.
then go back to your command prompt, and type
adb remount
adb push build.prop /system/build.prop
reboot phone twice after this.
The idea here is that these lines will force only searching for Edge networks, and improve the full use of multislot data/voice thoroughput on ATT Edge network. I would think technically that this would also maximize data thoroughput for those that want to save battery life from the sucking power of 3G.
I'm posting this because I'd like some feedback from ATT people that can try this. As I'm in metro Atlanta I'm not sure that these settings work for every area, and I've only tested in two spots here within a mile of each other in the three tests. I'm also at this point concerned about battery life outside of my one day testing and other areas.

I'll try this on two different G1's running on AT&T this next week and report back. Thanks
Update 8/31/10: Testing with Super D I see a difference. Was 0.07 mbps Down/ 0.08 mbps up. Now 0.18 mbps Down/ 0.16 mbps Up. Every little bit helps I guess. Thanks for posting this thread.

Which ROM are you using this on? I'll try this out on my phone at the end of the week. Also where did you find this exact same set up. I want to read more about it. I see other posts with different values but not with this same exact set up.
http://forum.xda-developers.com/showpost.php?p=5123531&postcount=46

As I mentioned I'm using Cyanogen 5.0.8. I didn't read where anyone is using this exact setup, I researched the values and put them together based on my best understanding of them.
As of now I'm seeing battery life unaffected to actually improved. Things like facebook and my MLB At Bat are majorly improved, takes much less time for the stats to populate so I'm spending less time in the apps and in turn I'm assuming that lends to battery life. I also used to drop a call in one particular spot and I'm not dropping that call so far. I've been in various parts of the city and the download speed is fairly consistent witht he 130-180k range.

Any word on this working with CM6? There only seems to be these in the RIL section:
ro.ril.hsxpa=1
ro.ril.gprsclass=10
Should the other two values be added?

As far as what should be added/removed, please more carefully read post one.
In answer to whether it works with CM6, these values directly support the gprs code of the phone so it should in theory work on any android based device.

I appreciate the time you've spent, thanks. I'm trying this asap. I have to test before and after, tho. I'll let you know. I never even considered looking into this, and what I see looks very promising. Thanks for the work.

In conclusion, no it didn't make any benefit to me. In fact, there was a decrease in speed after applying the mods.
I used a nightly of cyanogenmod 6 from 2 days ago (right before rc3)
I will try donut soon. Eclair sucks. Note that cyanogenmod did not have the last two ro.ril lines, but it did have the telephony one. I added the necessary ones, of course.

i updated my post above.

Hi Jcarrz, thanks for the post. I think something is wrong with your location/configuration if you are getting 100% upload speed over download. It should be the reverse, but even before my config change I was getting double your download speed. Also, a ping time of <100 ms into an edge network is a bit unheard of as far as I know, what speedtest are you using? Did you delete the existing lines? the two most important lines to add are the dtm=1 lines and the grprsclass=32.
One thing about this is that not every city may support class 32 download. Also it may take some time for GPRS to establish 5 timeslots to get the full download speed. Another thing to follow up on my post, as I mentioned 10 seconds or so at least before starting the speedtest, but I've found that even 1-2 minutes after coming from sleep I'm occasionally getting 215k down in some places. But in your case there's definately something else going on....

yea, that ping was pretty crazy. I live really close to los angeles, I don't think a crappy network is the problem. What do you mean by delete existing? i edited two that were there, and added two that weren't. I am using the ookla labs speedtest.net application. I have always had a higher upload than download. Everywhere. I waited for long periods of time between tests. And after waking up from sleep. The highest speed test I have seen is a 250, on htcclay's superfast 1.3.3. I'll have to take a look on the values in that rom.
Thanks for your help, prehaps you could upload the EXACT build.prop for, say, a cm6 build that I could use?
Jcarrz1

ro.ril.hsxpa=2
ro.ril.gprsclass=12
ro.telephony.default_network = 0
I seem to get the best speeds i've seen with this config. Namely the hsxpa=2, because that one, when changed to 1 or 0, dents my speeds.

Thanks for reporting back. I think this shows that indeed the edge network in your location just isn't a class 32, or at least it is and is allocating more timelosts for upload than download. Here's how the classes should in theory work. Edge can alot 2-6 timeslots to transfer data. a class 10 or 12 is 5 slots data, 10 says that in theory up to 4 of those slots could be download and 2 could be upload, while 12 is up to 4 down 4 up (but only 5 max in any config). A class 32 can allocate 6 slots data, 32 also says that 5 could be download or 5 could be upload. Try setting the class at 30. This will give you a shot at 6 slots guarantee that no more than one timeslot can be set for upload (5 download 1 upload). If that doesn't work, in theory actually then moving to a class 10 setting may overall benefit you (4 download 2 upload).
hsxpa setting should technically do nothing for you on AT&T unless your phone supports HSPDA 850/1900, I set it on my magic 32B because it forces UTMS99 which is not implemented and therefore should in theory guarantee my radio never finds something to scan. I understand that turning on 2G only doesn't work in all roms, so I set that just in case.
Just so you know, the values in gprsclass can be 10,12,30,31,32,33,34.

I don´t think that ro.ril.hsxpa=0 deactivates 3G. AFAIK it just limits the phone to plain normal 3G (=UMTS) and ensures that it does not attempt to switch to 3.5G (HSDPA/HSUPA) connections.
From what I see in wikipedia, UMTS99 is nothing else than the first release of UMTS, therefore definately being supported.
Better set it to =2, just in case you travel to a country where you have 3G (and 3.5G, etc.) connectivity.

EDIT: Sorry I just looked up the specs on the phones again and I never noticed UMTS support, still in essense you still want to keep this at hsxpa=0, unless you want 3G on roaming coverage as mentioned. This article is about ATT users and more geared to only ATT bands, ATT does not offer HSDPA over the bands this phone supports so disabling it should keep it from scanning roaming networks for it. I'm removing the other ril values from the phone to keep the phone happy with the fastest edge connection it can get.

So I just tried updating the settings on Superfly TCBY Froyo 1.2. It didn't have the same exact setting lines so I just added the lines manually. All tests done on a fresh reboot, SpeedTest the only app open:
Before
Time of day: 1:10 PM
Run 1
Server: Los Angeles, CA
Latency: 829 ms
Download: 10.3 kB/s
Upload: 9.3 kB/s
Run 2
Server: Los Angeles, CA
Latency: 121 ms
Download: 14.7 kB/s
Upload: 12.1 kB/s
After (2 reboots):
Time: 1:25 PM
Run 1
Server: Los Angeles, CA
Latency: 423 ms
Download: 19.9 kB/s
Upload: 13.7 kB/s
Run 2
Server: Los Angeles, CA
Latency: 394 ms
Download: 18.3 kB/s
Upload: 14.6 kB/s
So it did improve speeds a little. How much is due to the settings is unsure. It could be related to the time of day and traffic during the time of day. I will keep the settings and see how they hold up.
I have been using the normal settings without modifications for Google Nav and it works perfectly fine. I will see how these settings hold. I'll attach my build.prop. Just remove the ".txt"

dawgpound, can you report what city you are in. I do agree that time of day and tower can play into this, this is why my before and after tests were done about 2-3 miles apart from each other. They were also done during daytime hours.
To update on my end, I'm still testing in various areas of atlanta and I'm finding that I actually connect "G" in some areas. I'm assuming UMTS99 since the phone only supports this. The download speeds were terrible, worse than edge for me though. I know this implementation is older and probably not omptimized.
Using Speedtest I'm still not getting any worse than 40k download anywhere in metro atlanta. But, one thing I've found is that in some cases I would get a upload speed greater than download, running Speedtest again even immediately after would produce much higher downlad and upload speeds and maintain these. I think this goes back to my theory that when you initiate the data transfer that it takes a while for the phone to build all the timeslots to the carrier when you enable them in some situations.

Sorry for responding so late. I'm doing the tests in LA. I went to Universal Studios the other day with the modified settings and my phone failed badly when using data. I was getting full signal on my phone with the EDGE sign but it wasn't sending or receiving data most of the day.
Unfortunately, I wasn't able to switch back and forth to see if it was just in the theme park or not. I've noticed in crowded areas, it lags pretty bad compared to the stock settings. I also was connecting to G speeds in some areas but only for a few seconds before switching back to EDGE. Right now, I'm back on stock settings to compare. I will say though, with the modified settings, download speeds increased by average 5 kB/s but upload speed was on avg 5 kB/s less than dl speeds. Stock settings, both download and upload speeds are close to each other.

[Q] PdaNet not getting 4g LTE Speed Thunderbolt

I have tried both EasyTether and PdaNet to tether the thunderbolt. When I tether using the hotspot or tether using the "internet connection " mode and run a speedtest.net I get awesome results. When I tether using PdaNet or EasyTether I get what looks like 3g speeds at best. I have the free hotspot and tethering till May 15th but I will be cancelling that and moving to one of the two apps. Any Ideas?
ps- Yes, the signal is full bars 4g LTE. I even went as far as using lte on/off app to force 4g lte only.

I would email the app developer.
Maybe it needs further coding to utilise 4g

on the phone i get 30mb down, 2mb up. on easy tethered laptop, from same server i get 8mb down, 4mb up.
used speakeasy.net to run tests.

I think a lot of apps arent working with LTE. Opera is another one. That wont get any higher than 1.5 on LTE.

It's probably a combination of two things when using a non-root tether app:
1) The speed of the Android app itself.
2) The speed of your computer. Such apps push data through the adb interface, so there's an amount of software processing going on in the background. Try popping up a task manager (eg., Windows Task Manager) while performing a fast transfer and check to see if a process is consuming more CPU during the speedtest. If the CPU% is high for the duration of the transfer, your throughput is likely limited by your computer.
It's certainly possible to hit 4g LTE speeds with non-root tether apps, as someone has recently posted (anywhere from 14mbps to 28mbps for his setup, depending on the app).

with torreents it was all another story...then few torrent apps were released from which i used aTorrent(pro)...I am satisfied with its usage... sometimes the content would download at 1kb/s wouls compete in 10 -30 minutes... for slightly bigger ones it would take a night or more days to download but it would complete..
remember data exceeding the size of 20mb would never be able to be downloaded on 2g speed is impossible(would take months)...

Games take a loooooong time to load with wifi

I have a Samsung galaxy a70, my WiFi speed is pretty fast but it keeps loading games forever (unless I use mobile data or VPN). Although I still have yet to try another wifi network. But anyway, I play only two games, honkai impact 3rd and mobile Legends. Honkai impact 3rd just keeps showing me the loading icon for long after which it dissappears and comes again after like 2 seconds, and if I try online in the game, it doesn't let me join at all. As for Mobile Legends (it's a MOBA) the loading screen takes sooo long (it shows everyone's loading percentage) and I'm always the last one to load, the inside of the game is so smooth, my ping is usually 8ms. Even when I'm browsing Instagram, videos and comments will load as if my WiFi speed is 1kb/s. This doesn't affect any browser tho. Didn't try with Facebook. This only happens on my phone in the whole house.

Forgot to add: This randomly starts happening and goes away after pretty long

Maybe cause the server you're trying to connect is far away? idk i don't know about games that much.

Wireless networks use two main frequency bands: 2.4 GHz (gigahertz) and 5 GHz. These frequency bands affect how far and how fast data can travel over WiFi. The 2.4 GHz band gives you slower speeds at a longer range, while the 5 GHz band gives you faster speeds at a shorter range.
So, if you want the fastest WiFi speeds, you should always use the 5 GHz band. However, the more devices you have on one band, the slower your WiFi will be.

Wifi connection has nothing to do with loading screen .. what is your performance rating on Mobile Legends?

With regards to a Wi-Fi connection many aspects come into play, such as bandwidth, Internet speed and latency, among others.
When the mentioned games get launched they at 1st thing of all things fetch data / resources from Internet what will take some time which depends on the 3 above mentioned criteria. The progress typically gets shown on game's loading screen.
Same is the case when you from within the games try to establish a further Internet connection.
BTW: An Internet speed of 1KB/s indeed is really inacceptable. Normally the Internet speed is in the range of 700-800 KB/s.

goto Setting then Network Test then Performance Test and let Mobile Legends rate your device also fast loading screen have disadvantage you will never have time seeing enemy team hero selections and decide what equipment to buy to counter them ...
here's mine MediaTek Heli P20 rating on Mobile Legends not that fast but it's decent

It's not only on games, Instagram does not load videos at all, and my WiFi download speed is 5 mbps so I'm pretty sure it's not my WiFi at fault. As for mobile Legends, now that it added the data optimization thing at the start of the game, the loading speed is back to normal now. But honkai impact 3rd and Instagram remains the same, ESPECIALLY Instagram.
