[Q] HSPA data issue, Help!

Okay so here's what's happened.
My phone is the LG-925g from Rogers, and it's unlocked to work with Koodo. It WAS working just fine.
Sometime around my update to V20c (I don't know exactly when, so I can't say forsure it's the update) data stopped working properly on HSPA. It didn't entirely stop working, just sustained connections.
Let me explain.
On WIFI EVERYTHING works.
On 3G I can browse, check e-mails etc... but I can't download anything. Market I can browse, but not download. Youtube works in the browser, but not the youtube app. Shazam doesn't work. Facebook updates work in the browser, but not the Social+ widget. Weather updates fail.
I can browse and check e-mail and that's about it.
so data IS working, just not properly.
Here's what I've tried....
-Formatting NV partition
-Formatting Cache Partition
-Formatting internal SD Card
-Complete Phone Reset
-Took my phone to a Rogers store, hooked it up to the rogers cell network on a store-sim and it worked great
-Took my sim card to a koodo store, stuck it in a demo android phone, worked great.
- Factory Reset of phone
- (phone was not rooted at time of problem) rooted to install and use networking tools
-went into hidden menu 3845#*925#
-went into Other Hidden Menu: *#*#4636#*#*
-ran every test in hidden menu and looked for settings that may affect this
-Installed APN Remover to remove all APN's except Koodo
-Verified (with a koodo rep) every APN setting and even tried removing some or messing around with them
I'm about to downgrade and re-upgrade my phone to see if that works. Any chance that may fix it? any other possible solutions? I'll even take crazy solutions at this point because netstats pings, etc etc are not showing me anything, I just get a lot of Syn_sent connections without ACK's.
HELP! (And sorry for the wall of text)

have you tried setting up your APNs?

APN's
Yeah, I tried setting and resetting them a few times, even with a rep from the cell company.
I'm losing my mind!
Thanks anyways though!

Im using 21d. Seems to have somewhat similar problem. Getting unstable connections.
My problem:
phone kept switching from H to 3G to G and H again. Speedtest app revealed very low and inconsistent speeds..Reception bar also kept changing.
Phone was previously froyo. Im not sure if it's because of gingerbread baseband. I have some suspicions on that.

I agree. I think it's a GB thing. I'm on v21a, and I have the issue where upload arrow keep blinking, and I get the H -> 3G-> H.
EDIT:
I'm having this on v10d too

Unlocked Infuse makes T mobile calls but wont connect to web?

I have double and triple checked the APN settings. No luck. I feel like a complete retard, but why cant this phone connect to the network?
It doesn't even appear to try. Any suggestions?

I haven't a clue why, but I've been told multiple times that the infuse won't be able to connect to Tmobile data services in any manner.

I'm in the same boat, when did you notice this? I ask because mine just started doing this yesterday. Here's a brief synopsis of what I've done:
- I was running stock GB 2.3.6, from the Heimdall One-Click...had no issues for weeks (only had it a few weeks); once I realized that I can't get anything higher than EDGE speeds due to the hardware requirements, I went ahead and purchased the GN. So, my neighbor told me that she went to T-Mo (same phone) and the gentlemen 'input some codes' etc etc and she now had 3G (can't verify, I didn't grab her phone). I had an idea that he went into the phone testing mode (by doing the *#*#INFO#*#*) and maybe changed some of the network settings in there. So I figured I would give it a shot before I put it up for sale since my GN was coming today. So I went in and tried a few things, all to no avail....and then realized that I had NO data at all.
So at this point I did a factory reset (no luck), flashed the firmware/modem/etc from the Heimdall one-click, reset the APN settings (multiple times)....everything that I know to do with it....and STILL no data. But I can place calls, get texts, etc with no issue.
What's strange is after I flashed the stock GB rom, I went back into the testing mode (I guess that's what you call it???) and was checking a few things:
- if I run the ping test, it comes back null (no surprise) BUT it also lists 'GSM Service: In Service' and 'Network Type: EDGE'...it does show GPRS as disconnected.
I tried my SIM in an unlocked iPhone and it didn't have data connection. But I also put my roommates T-Mo SIM in the Infuse and it didn't have data either. I haven't had a chance to see if my SIM works (data wise) in the GN, because I haven't gotten it yet.
Any ideas on what to do?
**EDIT**
For some reason the data began to work about an hour after I posted this. Maybe the phone knew I was asking the experts and it had no where to hide?? Either way The_Joe I would try to maybe do a factory reset and if that doesn't work, to try to re-install the ROM/OS again.

New Motorola Defy, Major Connection Issues

Bought a brand new unlocked Moto Defy and I'm having some WiFi and data connection issues...
To start things off, I cannot get any kind of data on this phone. I'm able to make/receive calls and texts with no problem but when it comes to accessing data, it's a total fail. I've added APN's for ATT (ATT MMS, ATT PHONE, AT&T PTA), switched the 2G/3G/auto under Mobile Network Settings, and I just can't seem to get data working. I get data just fine on my At&t Samsung Focus with WP7.
Secondly, I cannot connect to my WiFi router. I've reset the router numerous times, disabled WPA security, tried different security methods, and it just doesn't want to connect. The network occasionally shows up with great signal strength but soon after disappears. I went to the same room as the router and it shows up. When I tap on it to connect, it shows "connecting" and then "disconnected". I also get a WiFi symbol in the upper left hand corner with a question mark over it.
And to top things off, I can't seem to format my WP7 memory card so I can't even install any apk's or ROMs. For some reason, the 2GB card that supposed to come with this phone wasn't even in the box!
Any ideas? Starting to get frustrated, this is my first android phone (3rd android device, first 2 were tablets) so I'm eager to mess with this thing.
Uploading a short video showing the WiFi problem.
Thank you so much!
Also, running 2.2.2

Anyone?

So I've installed Cyanogenmod 7 and was able to get to the band settings but when I select USA Band, it says "Set [USA Band] Unsuccessful.
I found a working bp_nvm_default folder for ATT, replaced original with that, set permissions, and nothing has changed.
I am at a loss of what to do now. And after installing CM7, I have no signal what so ever.
Please!!!! Any ideas?!?!?

[Q] Need help with connectivity issues. DESPERATE

Hey guys, quick background. I bricked my SGS3 and had to have it replaced. I think I got a refurb phone because from day one I keep having the same issue. First day I got the replacement phone I rooted it and flashed CleanROM 5.0. Everything was peachy until I noticed that I have no 4G or 3G service. In fact, I had no data connectivity at all. My phone can make calls, receive texts no problem, won't connect to internet. If I restart the phone, I have 4G right away. After a few minutes, the 4G icon is on, but the phone won't has no data connection (when I say data connection I mean it will not go online, no internet, no android market, still have voice and txts). If I attempt to go on internet, I get a message saying "No Signal Found For Mobile Networks". I have installed Network Signal Info and right after a restart it says 4G LTE, data connected, upload+download activity. After a few minutes, it says 4G LTE, data connected, after a little while, it will switch to EHRPD, with data "connecting". Also, in the System tab, it will tell me my IEMI and version of JB running, next to "Radio", it says "unknow". WiFi works perfectly btw. My IEMI is perfectly fine,
I had it backed up. My phone number is still there.
Here is what I had tried so far: Switching into and out of Airplane mode, different programs that reset mobile connection, flashed different custom ROMs, flashed the stock kernel, flashed 3 or 4 verizon Modems, Data wipe, cache, Dalvik wipe, Odin'ed back to stock 4.0.1 ICS and had upgraded it to 4.1.1 via verizon software update, changed the SIM card, and reprovisioned the phone with that *3767*whatever the hell code. I'm out ideas.
If anyone has any other idea that I can try before I take it back to Verizon, please, let me know.

Did you go into your mobile data settings to make sure you're on CDMA/LTE? If not I would select and reboot the phone and see if the problem persists. I don't know if you have tried this but it's worth a shot.

I'm having literally the same exact problem with my mom's S3 except for it's not rooted, complete with 'download + upload activity' and 'unknown' radio. I've yet to find anything in my search, but if I do I'll post it here.

APN doesn't update default settings

Hi.
Please help me. I CAN'T USE MY MOBILE INTERNET
I used all my Vodafone data and I have decided to try a new company out, so I have transferred the number to Lebara yesterday and since then I'm struggling along with the customer service with setting up an internet connection on my 16 GB OnePlus One.
I have tried installing 3 different ROM's several times - Oxygen OS, CM 12.1 and BlissPop v4.0.
Before installing the ROM's I deleted the following: Cache, Dalvic Cache, System, Data. However when installing the different ROM's the log box showed me messages like "installing radio system/ ... / (...) already up to date" so I'm assuming deleting basically "everything" from the phone still doesn't get rid of some of the files in the system. I think that this is where the problem sits.
Although I can save my Lebara APN, it feels like it is not set to default.
Whenever I go into APN settings after freshly installing any of the new ROM's along with the GAPPS the 3 vodafone APN's show up which I have set up few months ago BUT THE LEBARA APN IS NOT SAVED.
When I press to reset APN to default it will again get rid of all the APN's that I would add and replace them with the 3 vodafone APN's.
There is an exclamation mark next to the GSM status icon
There is this message popping up every 10-20 seconds "Sign into network - Lebara". Whenever I click on it - a 10% bar shows up and doesn't progress anywhere. After around 30sec-1min the windows would just disappear and the message would pop up again etc. etc.
However if the windows is opened I am able to tap a 3-dot button in the top right corner and then select "use this network as is" this will close the window, the message will not pop up again and the H or H+ letter would finally show on the GSM status icon and the exclamation mark will disappear.
HOWEVER THE INTERNET WILL STILL NOT WORK - the browser would just timeout itself every DAMN time.
I think I should go back to the system files and maybe delete them manually and then install a fresh copy of CM 12.1, since it's the most stable out of all of the 3 mentioned above.
What do you guys suggest?

look at what network mode your opo is in, preferrably in LTE/WCMA/GSM
don't worry if the APNs don't get saved, you should worr if they get activated
btw LTE is not really available in germany (only fast 100mb/s LTE at vodafone & telekom), the normal 50mb/s LTE used by almost every provider is cannot be used by the opo because it misses the appropriate bands in the modem
