Terrible data speeds....

Picked this phone up yesterday second hand. It was rooted when I received it and started crashing anytime I would try to install and application. Did a hard reset and it ended up getting stuck in bootloop. Finally got it restored via the threads on here and re-rooted....however the phone will not connect to LTE now, and my data speeds are slooooww (.10kbps download .05kbps upload)...with full "4G" HSPA signal. Any ideas?

Maybe your APN settings are out of whack. I don't know much about it, but let me get my phone and I'll edit this post to add the APN settings.
The APN should show in the list of APNs as:
ATT PTA
pta
The settings for it are:
Name: ATT PTA
APN: pta
Proxy: <not set>
Port: <not set>
Username: <not set>
Password: <not set>
Server: <not set>
MMSC: http://mmsc.mobile.att.net
MMS Proxy: proxy.mobile.att.net
MMS port: 80
MCC: 310
MNC: 410
Authentication Type: None
APN type: default,mms,supl,hipri (no spaces)
Hope this helps.

Is it a 4G sim? Not sure that makes a difference.

Are you certain your are not in top 5% of heavy data users?

I believe 3G SIM card won't work without changing APN.

I would imagine that I only use about 250MB...so no. I got a brand new SIM this morning from AT&T and was told it was the newest revision.

Should Brady try installing one of the ROMs guys and see if it fixes some kind of software issue that might be imaged on the phone by the previous owner?
Also, worst case scenario, you should still be able to send it back to LG under warranty since it's last than a year old.

Now I'm curious what the previous owner did to fudge the phone up that bad that the signal is shot.

Do you have another phone to test your sim card in?

Silly question, where do you live? I ask because LTE is only available in a very few markets.

Tried the SIM in another phone, however it wasn't 4G compatible so it didn't help. I live in Houston, Texas. When I called into tech support, they said I was less than half a mile from an LTE tower. Even HSPA+ should be getting better than 1/10 MB second.....

Yes, HSPA+ should get you 3-5MB/second. The .10MB/sec is edge speed. LTE will get you at least 15-20MB/sec. Here in DFW I get over 50MB/sec sometimes.

Was it the same speed or slightly faster? You know it would make a difference, we are troubleshooting here...
Go to settings -> about -> status
what does it say in the mobile network type?

Here comes the Mb/sec Mbps confusion... Your numbers are written as MegaBytes, yet you meant MegaBits, it's 8 times difference right there.

Tried the phone in an old 3G phone. Data was faster. Its definitely the phone and not the card. Says HSPA under network type

What is it supposed to show at the network type when phone connected to LTE?
The next attempt I'd do is to backup all partitions:
Code:
cat /dev/block/mmcblk0p1 > /sdcard/firmware-backup.img
cat /dev/block/mmcblk0p8 > /sdcard/boot-backup.img
cat /dev/block/mmcblk0p13 > /sdcard/recovery-backup.img
cat /dev/block/mmcblk0p14 > /sdcard/baseband-backup.img
cat /dev/block/mmcblk0p27 > /sdcard/system-backup.img
(you must have root and these commands executed either in adb shell or console app on the phone)
then skipping to "Restoring Nitro HD partition images" at the [Solved] Unbricking Solution for LG Nitro HD | Confirmed Working on Bell Optimus

Oops, you're right. I put that in wrong my numbers are Mbps... not MBps. Either way, its a bad benchmark I know. But its something to reference at least.

Question about Arc S 3G

Hey, I have the L18i Arc S and am unable to get 3g thorough T Mobile or At&t in New York. Now my question is, would I be able to get 3G through any of the service providers by flashing a different ROM ? I know T Mobile frequency doesn't allow that so I guess the only choice left is At&t. Is there anything I can do to get 3G through At&t on my L18i Arc S ?

No, you should have bought a LT18a.
LT18i has no 3G connection is the states as it's missing the US specific frequencies for 3G and 4G/HSPA+

please help.... LT18a no 3G under straight talk
hey guys, i'm new to XDA. I didn't want to make a new post because it seems that my question has been asked. unfortunately my issue is a bit more technical, I recently bought a lt18a and for the past week I have not been able to get 3G to work. I found a work-around that Straight Talk works under AT&T network so I didn't have to pay their insane prices, but the 3G is not coming up no matter where I went. (I looked up an AT&T tower, drove there just to test out the phone and still nothing) I bought the SIM from straight talk's site and followed their direction on the APN settings I got EDGE to work but no 3G.
I have called straight talk but their infamous awful tech support was no use to me. I also check on other forums and still nothing.

Hello all. This is my first post as well and My friend has the same problem. I did research all over the web and i can't find a normal explanation to why it wont work on AT&T 3G HSPA + network. Does anyone have any info on this matter? All help is greatly appriciated.

If you set it to GSM only, then 3G is turned off/not in use. You need to set it to use WCDMA preferred.

GSM Galaxy Nexus with AT&T

So I recently received my nexus, and set it up with cm10 nightlies, but i seem to never have a data connection. I've looked online for apns and have tried every one but I always get connection for a few minutes, but then disconnects. This happens periodically throughout the day. And I know its not where I live because I was getting a great connection on my skyrocket. So I guess my question is what apn's are you guys using for att? Or maybe do you think I have a broken phone that needs to be sent back. I really wanna keep this phone, but the constant data disconnects are frustrating me! I hope this makes some sense, lol. Anyways, thanks!

Once you installed CM10, were the APNs intact or was the list empty?
I've just looked at my GN, also on AT&T, and found the following:
NAME: ATT
APN: wap.cingular
Proxy: <Not set>
Port: <Not set>
Username: [email protected]
Password: <Not set>
Server: <Not set>
MMSC: http://mmsc.cingular.com
MMS proxy: wireless.cingular.com
MMS port: 80

MNC: 410
Authentication type: <Not set>
APN type: default,supl,mms
APN protocol: IPv4
APN enable/disable: (checked off, but is grayed out and says 'APN enabled')
Bearer: unspecified
I think these APN settings are pretty standard. They were put into place by CM10 and I haven't touched them. Coincidentally, I was just about to flash back to stock; if you'd like, I'll double-check these settings once I've done so.
Good luck.

Did you test the phone before flashing nightly roms? maybe try pushing it back to stock and see if that is the issue

So yes I was on stock and I was having the same issues. That's why I flashed cm10 to see if it would help. I have the exact same apns as you do. And when it connects I'll have 5 bars. And literally within a minute, I see it drop all the way down to no bars and then it disconnects from the network. Thanks for the replies. I'm starting to think that I should exchange it for another one to see if its just the phone.

It is my understanding that the GS2 Skyrocket being an LTE device your account and is provisioned for the pta APN.
I am in the middle of something right now, but tomorrow I will post the pta APN info.

T-Mobile 4G on ATT GSIII

Hi
So long story short, my Tmo GS3 got stolen at my work :/
So my mom gave me her ATT GS3 cus she was up for an upgrade,
i been reading its possible to get 4G on an ATT GS3 but so far no luck,
i know i have the right APN cus i copied the one from my Nex4 to my GS3, i set the network to manual and choose Tmo, but still all i get is Edge.
Does it have to do something with the way i unlocked the phone?
I been reading it has to be factory unlock and i unlocked mine by dialing *#197328640# and doing the required steps.
Can anyone help me with this?

Do a little bit of search work; it depends on the coverage for T-Mobile in your area. It's still a Work in Progress to get the 1700 Mhz band to work on a ATT GS3 since there's a bounty for it in the General section.
Setting the APN to what you have on the Nex4 won't do anything because it's all software and hardware controlled. The software part is currently locked down because no one knows what to change to get the hardware to send and recieve information from the 1700Mhz Band.
Your best bet is to check the coverage map and hope you get 3G service or wait until T-Mobile Rolls out their 4G so the old EDGE will switch onto HSPA for ATT devices that use a T-Mobile Network.
Hope this helps

I had the same situation: only edge, after flashing this files i have 4g http://forum.xda-developers.com/showthread.php?t=1771021&page=25.
Start reading from post #246. If you flash the files you must root your phone like it is a t999, also goes for recovery, im not sure about kernel and DO NOT flash another modem/radio.

Ok I have the same configuration mine said 3g change to h+ and 4g for one minute but my s6 always on 4g lte any clue????

I'm having the same issue. Only h+ and I have the same settings

I pulled my card from S6 to the ZF2 just like godgib and it worked right away (Just shows 4G, there is no LTE icon). You guys put it in the SIM1 slot right?

I had a similar problem with one of my new Zen 2, I was not able to even get Cell network nor any mobile networks.
I had to call the carrier and have the IME # added to their service and after 5 mins everything worked.

I had to change from ipv4 to ipv4/ipv6 to get lte. Some reason, for some people, the apn otb is not correct.

No issue on my end, was just plug and play.

Make sure you have the latest OTA updates as some of the earlier releases had incorrect APN settings for T-Mobile.

Not related to LTE but something I've noticed otherwise.. It looks like this phone does not do actual dual stack. ipv4 works fine on its own, as does ipv6. But by selecting ipv4/ipv6, clat4 is used for ipv4 support. This would be all well and good, except clat4 does not seem to load reliably. More times than not, I'm still stuck with ipv6 only. And while nat64/dns64 works, there are a ton of apps that make use of hardcoded ipv4 addresses.

I was able to get LTE (once I figured out that the 4G icon=LTE), but it want as strong as on my Xperia Z3.
I ran some speed tests on both phones in myhome office where it iis used most and any local Starbucks; likely where I use it second most. In both cases my Z3 beat the Zenfone 2 64GB.
Also of interest was that in an AnTuTu test of both phones, while the Zenfone 2 scored higher than my Z3 (48k vs 43k), in the test detail, the Z3 beat the Zenfone in a few categories including the single core test.
Needless to say, the Zenfone 2 went back to Amazon today.
