I'm getting crappy download, upload, and 3G connectivity speeds on my Virgin Mobile LG Optimus V. I'm rooted, running CyanogenMod-7.2.0-BACKside-IHO-KANG, Build ID: eng.jerry.20111122.082819, Build Number: GRJ90 (11222011/VM670), and Kernal Version: 2.6.32.9-v3.3 [email protected] #1, and Android Version: 2.3.7.
I've read that flashing Franco Kernal may help a little bit with network speeds, but that was for the Optimus S. The Optimus S & V are pretty much the same, so would it be safe to flash Franco's Kernel with the ROM that I'm using now?
I've also read that dialing ##3282#, and editing the HTTP PD Port to value 0 and Address to 0.0.0.0 would then increase download speeds by 0.20-0.60 MBPS, but that was for the HTC Evo. I tried dialing to service code ##3282# on my dialer, and nothing happened.
Finally, I also read that doing a PRL Update manually and inserting/replacing Virgin Mobiles PRL file with a new and updated PRL file will significantly increase signal and speeds, but its risky, and requires depth to do so. Also, it allows to connect to Verizon's towers, therefore it would then not allow any data connectivity for browser, market, etc.
So, folks, my question is, is there ANYTHING or ANY WAY I can improve my download/browser speeds? Would downloading a proxy app from the Market work and apply faster speeds for downloading on my phone?
Thanks for any and all help, as it will be greatly appreciated!
3g turbocharger script
try that
and PRL update
proxy? naw dog you'd be doing it wrong
try this too

I just downloaded the Set DNS app from the link you gave, but where do I find DNS servers to use?
And the PRL update and 3G supercharged script looks very difficult for a noob like me lol I mean I kno android very well, just never did a PRL update or scripting

It is super difficult. And really it'd be like putting a supercharger on a pinto. Sounds great when you tell your friends, but you're not going to win any races. The real problem is sprints network, and the fact that we buy the cheapest service available from people who lease a very small percentage of their bandwidth. I get 50- 125 kbps consistently. Not allot to do besides try another carrier.

Yeah for real! That's no joke lol I might try doing a PRL update tonight, but that's a big maybe. I used to get 200kbps download when I first got with Virgin Mobile with the LG Optimus V, now it seems my speeds are slowly deteriorating. And it doesn't help that Virgin Mobile is gonna bring a data cap on their 3G in 2012 to only 2.5GB, after that, they are gonna put a maximum set download speed cap after the customer uses up the 2.5GB in the month. Which sucks for me bc I'm always on Facebook, Linkdin, Twitter, browsing the market, web, downloading, etc. :/
Well social media doesn't take up very much data at all, it's the downloads that might get you if you use them a lot.

I downloaded it, and changed the DNS to FOOLDNS and I can definitely tell a difference in speeds. Tapatalk loads super fast now

ok thanks. i may try it. still a little skeptical as a few of the comments mentioned that it broke their wifi and that the developer didn't respond to their emails.
franco's kernel is for the msm7227 chipset (unless he built one for the OS I'm unaware of,) the OV/OS have msm7627.
they are NOT compatible.
I got nasty side effects back when I flashed a msm7227 kernel on my OV for experimental purposes. it took a couple of days before it would boot consistently again even though I put a compatible kernel back on it immediately after it locked up ugly from the wrong chipset compiled kernel. It would freeze on boot until the battery was pulled for a minute or two.
I can get much better download speeds in a debian chroot on the OV with multiple download threads, using axel, but I don't know of any way to multithread downloads in Android.
As an example, my average DL speed ranges from 1-30K/sec. With axel, I can pull down over 100K/sec, with no other variables obviously changed. the Android browser very rarely goes over 100K/sec on my OV. (I am in a lousy service area.)
SetDNS (or other similar apps) "speed up the connection" by taking some of the guess work out of trying to find the resource on the web.
Most of the slowness in wireless comes from the fact that a wireless network is like a hub (in that it's a shared medium) so if two or more people transmit at the same time there is a network collision (two or more signals interfear with each other keeping the tower from understanding the request) per TCP/IP protocal all devices involved in the collision must back off for a random amount of time (to ensure they don't all retransmit at the same time again) and try again. This effect grows as the size of the wireless network grows and the more people who are on it. It effects cellular much more than wifi as you can have many more people on a cell tower as it covers much more ground.
***Intermission***
Now when your phone makes a DNS request (usually the browser, but some apps as well) there are actually many steps involved in trying to turn a url into an ip address, there are mutliple ways other than dns to turn a url into an address (most of which are legacy but it still tries anyway) trying all of these ways in addition to trying to find a DNS server means multiple request on the network which increases the likelyhood of collisions thus increasing the latency and causing timeouts (this is why sometimes your browser will start to load a page and then just hang there for awhile.)
***Almost there, Hang on just a little longer***
Now back to setDNS, this app allows you to specify a dns IP address (instead of it trying to find one) thus forcing it to use that address before trying anyother method, so your phone browser (or app) doesn't waste time looking for a dns or trying legacy methods. Thus reducing the request and collision/timeouts on a network, overall making your phone load stuff much quicker.
Works well enough that I use the web version of gmail and google reader instead of native apps (though native apps are generally quicker as they don't have to load the ui everytime you open it and sometimes the app will use an ip instead of a url, though some apps use url's in the code because the resources at needs have dynamically allocated (and thus always changing) ip addresses.)
Does anyone know if the Turbo/Supercharger scripts actually work? I assume any difference seen is minimal and also it may wear down your battery even faster. Battery life on these phones is already precious.
Hi there,
I'm getting a strange issue with internet connectivity on my SGS3.
It's still the stock firmware. However, it's rooted with the Siyah kernel to counter the audio crackle issue.
The problem is the speed. my XDA forum app, gmail and most of all Google Play store time out, yet on speedtest i'm getting 5+mbps down and 2mbps up. The browser performance is ok when this issue occurs, but certainly not 5mbps good. The issue only presents on HSDPA, and is not so bad on WiFi.
Should I flash to a new rom? Is there an issue with Siyah and the stock firmware?
Confused!
The reason why you time out might be due to an unstable internet connection, however I'm not sure how it would affect you through network data.

Please check :
- Is the DNS Server slow?
Try using an App in the market to change the DNS Server to e.g. the Google IP's (8.8.8.8 and 8.8.4.4)
- Does your APN use a proxy? (Is it required?)
Maybe the proxy-server is overloaded. An alternative for testing is to use a VPN
- When the issue appears; does it go from H/H+ to 3G and then back to H/H+? Or are there extreme changes in signal bars?
That means you've been moved to another antenna or receiver on the same antenna. Try another modem.
However take care only to use modems coming from firmwares with the same letter as your firmware has at the 4th-last position
(Eg: BLFB firmware requires BLFB modem or newer)
My timeout issue (with which I've been plagued at the beginngin) got far better when I removed the Proxy in the APN settings and disappeared on BLFB -based firmware (Omega 8.0/8.1) with the asian DXLF3 modem.

Thank you so much for your quick response!
I've added the DNS app. Hopefully I get some good results. I'm on Australia's "premium" network, but have noticed that lately in the last 6 months or so, their performance vastly slipping. Mostly due to congestion from people migrating from other networks.
The reception is always full. Even in lifts, so that's a bonus. It's just that their throughput is a little dicey in peak times. During the lunch period in the central business district, i'm lucky to get a google search to load.
There is no proxy settings in the APN. So i guess congestion might very well be the case. I was just confused as the speedtest showed that the speed was pretty good..
Thanks again for your quick and helpful response!
Anyone know of an app that will boost my wifi speed at work over others?
Server speed is good just so many other devices and pcs it makes mine very slow. Its very frustrating 
Thanks in advance

you can configure this on your wifi router. if your wifi ap is basic one it might not have this settings. but most routers come with option to set high priority, qos etc.
Im at work tho mate.. im sure this can be done with just my phone

Cannot see how a receiver can receive priority over others without it being set at source .
jje
The whole point of Traffic shaping would be lost if any device can set itself to a higher priority.
Some packets can set an URG-flag which stands for least-latency routing instead of least-cost routing however it's still the router's call if he respects this and if yes how he treats them.
Something else is probably incorrectly configured. It's been reported several times that the S3 is very picky when several Wifi AP's with the same name (SSID) and in reach of each other are configured on the same channel (frequency). However most hobby-admins even know not to do that, so if your company is doing it you might suggest basic network training for your IT guys. (The basics of the Wifi protocol are in roughly the 3. semester at university)
You might want to try whether forcing the device to 5Ghz band will make it better since that band is far less crowded.
Also you could check WHAT causes the issues. Often it's not the bandwith by itself but either the router's connection table (a VPN to an external server is a very good but cumbersome solution) or the DHCP (use OpenDNS or Google DNS)

Because, according to your latest signature, you're on ParanoidAndroid which is not Sammy-based.
This information was lacking in your prior post.
Im using omega.. is this only possible on samsung based roms? Would it make much difference in me doing it? Id be happy to flash a sammy rom if it can get me a better connection at work. It takes around 10 mins just to post on here when im at work. And thats only after turning wifi off and on. I get good signal at work, and the speed tests are good. Hmmm

Hey there fellas,
I tried to find something on the forums regarding this matter, but I found a very annoying bug/habit. I'm currently on InsertCoin 2.3.1 and tried a wide variety of modem firmwares, but when I'm in areas where I have a very bad signal (in the gym's basement, for example), I completely lose connection to my network provider from time to time. Sometimes, when my device is reconnecting, it cannot reestablish a mobile data connection. When this happens, I can't make or receive calls either, even though the signal bar shows a valid connection!
In a nutshell: After losing signal, the device seems to reconnect to the provider network, but not properly. Can't make phone calls, can't send or receive SMS, only indicator for this is the missing mobile data connection icon. Only a restart resolves this problem, but I'm not happy with restarting my phone multiple times a day!
Here are some topics that seem similar to my problem:
http://forum.xda-developers.com/showthread.php?t=1782204&highlight=losing+signal
http://www.samsunggalaxys3forum.com.../1214-losing-connection-cellular-network.html
As I said, I already tried different modem firmwares, always with the same result. Can anybody help me with that matter?

Solution: Check your current CSC and make sure it's set to your specific country!
I have the same issue from when I had stock ICS and now still the same with Jellybean.

Checklist Network,
One enter settings for network APN etc .
Two correct modem for network phone and location .
Three correct CSC for network/area
Four problem on original phone providers rom and modem ???
Five might be worth investigation of RIL .

I have the same issue.. at first I thought it was due to the crappy network provider .. however I tried putting my sim in my old Nokia e5 and got decent signal strength even in areas where the s3 was unable to connect to the network. I faced the same problem even in stock ROM updated to latest version available for my region.
Any help would be much appreciay .

I used to have this problem with my stock ICS rom, exactly the same situation you described. Can't make any call after coming out from a tube.
I9300XXDLJ4 (4.1.1) is all good in reconnecting the signal.

Okay, after a few days of testing and trying to get a bad signal on purpose, it seems that setting up the CSC did the trick for me. After flashing InsertCoin, I had a French CSC. So I switched it to Germany and now the reconnect issues seem to be gone! There is a very handy CSC switching tool for free in the Playstore, but be careful, your ROM must support MultiCSC and switching the CSC wipes your internal memory!
Hi all,
I'm using the default application "Router WI-FI" on HD2.
I'd want to know if there is some setting (maybe in system reg?) useful to increase the WI-FI signal
(in SETTINGS-->CONNECTIONS-->WI-FI-->ADVANCED (I don't know if translation is correct, my WM is in Italian) I've already set BETTER PERFOMANCE)
... with this setting if I'm in the same room of HD2 I can connect an other device but if I go in another room (the next room, not upstairs...) the connection isn't any more possible... the signal is too poor
Thanks
No idea?
Doubt you can do any more than the best performance setting as the hardware in terms of antenna is biggest issue.
You could try WMWiFi Router software & see if that gives better signal performance as it is now offered free

My dear, u do 1 thing u replace windows with android...
WIFI works great.
Works fine with WM6.5.5 & WMWiFi Router.
If signal range is weak either you are trying go beyond the ability of the hardware or you have the HD2 issue with poor connection on spring contacts to the WiFi antenna (sometimes caused by bad/careless handling on repaired devices)
In my opinion the wifi works ok.
I can connect the HD2 to other wifi nets also if they haven't a so good signal.
It seems only when the HD2 has to be a router that the signal transmitted is poor :/
