[Q] Fringe 4g data drop - wtf?

I live in an area mostly covered by "4g" LTE. My charge will sometimes connect to LTE in my bedroom, but most of the time it can't. Every time it briefly connects to 4g in my home, however, it does not hand back off to 3g for a good 5 minutes or so. Instead, I lose all data connectivity. I've tried turning data mode off then back on, but it doesn't work. After about 5 minutes or so with no data signal, it'll reconnect to 3g. Does anyone know what could be causing this? Is there a way to fix it without just turning the LTE off (switching to CDMA only)? I get LTE in most areas around my house but apparently I live in a Faraday cage or black hole or something.
This is a 100% stock ROM, not rooted, never flashed any new ROMs or Modems.

Man, I have the same issue. I feel ur pain. I was downloading files on 4G and at around 34 percent, it cut out and went on 1x. Stayed there. And I was outside in a wide open spot. It happens man, I was told there's something wrong that causes the data signal cycling like that. I've tried what u tried also. If u can get a straight answer, let me know too lol. And to top it all off, HORRIBLE BATTERY LIFE.

The handoff process from LTE to CDMA is still pretty cagey. Fortunately, it's mostly software, so updates should help this process.
I haven't done any research on whether EP1F or EP1H (the leaked Gingerbread builds) are any better at it, but I would have to assume that it's part of the process they're working on with modem updates, etc.

when i was with ep1f the radio worked better for me. i was able to connect more frequently to 4g and switching was hassle free (no time outs). it's possible that the problem is on verizon's side since my cousin, who's on stock, is having the same problems in an entirely 4g area.

You might have a ****ty SIM card.
When I first got my Charge it was very similar to your situation. I had poor 4G connectivity in my supposed "fringe" area. Then a week ago it was losing connectivity from 4G to 3G and eventually stopped getting 3G all together.
I got a new SIM and now I get 4G in places where I only get 1 to 2 bars of call signal.
And I also stay on 4G a lot longer. Almost never does it switch over on long downloads or streaming vid.
PS: HAHAHA "long downloads". Sometimes a 300MB download will take much less than a minute depending on where it's coming from.
It must suck to make believe you have fast data. Right, AT&T? HAHAHAHA WiMax!!!

Anyone else getting horrid data connectivity on their TB? I usually never have data connectivity issues. In fact I was running just fine on the same ROM as recently as last week. But about 4 or 5 days ago, it went to total ****.
It has gotten so bad that I can't use 4g for more than 60 seconds. 3g is somewhat more reliable, but seems to drop down to 1x regularly.
I'm in the houston area and running BAMF Forever 1.09.
Do I need to get a sim replacement or something?

Try a new rom... I was using BAMF and noticed the same issue. Switched over to SHIFTAO5P with a Imoseyan kernel and haven't had any issues. Much snappier than the phone was previously and I haven't had any trouble with 4g. No trouble with data at all actually.

I am having issues too. Especially in buildings where I had a 3 bar 4g signal before, I am now not even picking up a 4g signal. Also, the 3g signal only reaches a bar at best. Almost like an antennae problem or something. But again, it just started within the last week. Co-inky-dink? (Detroit btw)

Running SOAB 1.3 in North Houston area, data has been spotty for awhile now, but not awful.

Yes, so, desperation sets in rather quickly when your phone internet is garbage, I suppose I must be an addict.
I tried many things today:
-Flashed old radios
-ReFlashed new radios
-Flashed new rom
-Flashed old rom
-Pulling/Replacing the battery (don't laugh, I told you I was desperate)
-Drove around the city testing various areas for connection quality
-Went into the verizon store and demanded a SIM card replacement
Perhaps the most painful of the steps I took was the last one. While they were replacing my SIM and giving me odd looks for having a rooted system, I meandered over to the Rezound station. Big mistake. I downloaded speedtest and android terminal, and repeatedly ran the bandwidth test and pinged google from terminal.
Consistent 75ms ping to google, consistent 27mbps down 11mbps up.
I tried the same thing outside the store with my TB, so I could take advantage of any network smoke and mirrors they may be using
My TB: Consistent 220ms ping to google, inconsistent 4mbps down 0.5mbps up
How depressing that was. Nothing has worked. 4g has been unusable for over a week now and 3g is slow as a snail, and only slightly more reliable. I am convinced I have a marginally defective handset and there is nothing I can do to get my 4G back except pay for a new phone.
I might buy my ticket to the TB haters' ball while I'm at it.

Just curious, but why didn't you unroot and turn s-on before going to the store?

Good question, I did think about doing that but ultimately my laziness prevailed. First of all, I am not a serial flasher by nature so I find it somewhat inconvenient to be constantly re-setting-up my accounts/contacts/apps/lookandfeel.
I justified going into the store because I knew if I played dumb and insisted walking out of the store with my handset in hand, that there was likely nothing that would happen. Never underestimate the complacence of an employee on commission who is doing something for you that does not involve earning a commission.

What radio are you using and does SHIFTAO5P have permission revocation as well as an uncrippled bluetooth stack (keyboard, wiimote, ps3 support).

So , I got my refurb on Saturday and I confirmed that the issue was hardware related. I did one final test to make sure. My setup was:
Both phones:
no SD card
stock GB MR (unrooted)
same sim card
Fresh wipe/update install
same battery
I installed Speedtest.net (Houston, TX comcast test server) and terminal emulator on both phones and sat in the same chair in my house for testing both phones (had to do 1 at a time due to sim card and battery, obviously).
My first phone (defective):
Speedtest server ping: ~220ms
Speedtest down speed: 500kbps
speedtest up speed: 400kbps
google.com ping: ~180ms, 5% packets dropped.
note: 4g connection indicator (in status bar) would drop randomly during speedtest, also about 2 of the speedtest attempts failed with "connection error"
Refurb:
Speedtest server ping: ~80ms
Speedtest down speed: 26000kbps
speedtest up speed: 9000kbps
google.com ping: ~80ms, 0% packets dropped.
no errors
Ran the test 5 times on each phone in a row, results were clear as day, my original unit somehow got ****ed up 4g hardware.

I have a similar issue as the OP. I was going to start a thread. My issues are a little more of the data connection on/off every 10 seconds. I'm actually flashing the newest shift AOSP now. If this doesn't go away... I will kill...

I'm having the same issues as both op and the poster in post #11. I may try for another refurb, but I'm not sure. I tried that route once before and all three were junk. I think this phone has turned into a major fail by htc.

I unrooted a couple weeks ago as I was rooted from launch date, started at mr1 and took the otas and the connection seems to be more stable for whatever reason. Even though I had run just a basic rooted 2.11.605.5 ROM with the ota radios.

I'm over in the NY area and ever since I woke up from work this morning I have been unable to keep a cellular data lock for more than 30 seconds (3g or 4g). I am rooted and am using a custom ROM, but I haven't changed it in nearly 4 months (haven't even updated it).

Explain this signal issue please (in Chicago)

Traveled to downstate IL today. We had a few storms through out the state so it could be outages. With that said, I live two blocks from the tower here in the city of Chicago on the north side.
I am always in strong 4G at home full bars. Right now I'm at 1 bar of 4G w/ D/L speeds for 1.3Mbps and 0 upload. My signal strength is -67dBm and 23asu.
I was in 3G areas the majority of the day but noticed when I got back into my living areas 4G was acting as it is now.
Currently running Synergy r68 build with Ziggy's kernel.
I've tried everything. Powered down, pulled sim, powered on, waiting for no sim display, then powered down, re-inserted sim, powered on. Tried factory reset. Tried going back to stock. Tried airplane mode. Tried airplane mode, power down, then power on, then turn off airplane mode....
Nothing.
So what do you all think? Tower issues?
ETA: I also tried flashing all three radios....those didn't help either.

You have multiple phones right? Pop your sim in a different phone. Sounds like a tower/network issue.

Just sold off all my Nexii (including both VZW Gnex's)
Was hoping some of the other Chi town people would chime in. I'm thinking tower issue also. But only on the 4G side of things. 3G is strong as always when switching to CDMA in phone info.

Just to update I'm in the south loop of Chicago right now in the middle of a hospital with strong 4g...tower must be down around where I live.

Who knows....here's a screen for ya'll. Last night on the north side...today on the south side of the city. And on a separate note my speeds are never this good on the north side.

How were your speeds before changing your ROM & kernel? I haven't formally tested but I suspect I'm a little slower now on CM10 nightlies than I was on stock. I'm willing to accept that for now, I enjoy the flashing and I know it'll eventually get fixed. Lots of comments about speed issues over on that thread (in the development section). I suppose a good test would be to go back to stock and run some tests.

I'm in the south loop with strong signal too. Thought I'd chime in.

Im on the Northside and as you can see no issues.

I just ran a speed test. 5845kbps down and 399kbps up. I know it's not my phone as evidenced the other day in the south loop with a very quick D/L and U/L speeds tested numerous times over the course of 8 hours.
I'm guessing the tower that my phone deems necessary to connect to is overloaded. I'm between belmont and diversey around the Masonic Hospital.
ETA: Just ran a few more tests. Averaging out to about 18 down and 4 up....much better than the 5 down I saw a few minutes ago. Latency averages are around 45 to 50 ms.

Download speed slow, upload fast

I live in boston and everytime I enter the subway and come back up, my phone has this habit of only getting around 60kbps down and 700 kbps up. I can go home, walk around, and nothing will change; however, if I update my prl my download speeds will go from 60kbps to normal around 1000 (1 meg). This has only started happening during the past week. I'm running a modified version of MikG shifted, but have had it for a while. Any idea why after losing signal for a while, updating prl fixes my download speeds?

First thing I would check on is Sprint. Make sure they're are not working the Network in your area. I've had some strange stuff happen while they are Updating the network.

Question about my data speed (Sprint)

What I would like to do is just present my situation and get anybody's thoughts on it.
I have a Nexus 5 running LP with cataclysm rom. I am on the Sprint Network. I live in Rexburg, ID and have a good LTE connection and 3G, but Sprint Spark is not available in my area. I'm on a sprint plan that includes unlimited data.
Okay so basically aside from 8-10am ish, at any given time my LTE speeds (shown with ookla speedtest) are at about 0.30 mpbs, not 30, but 0.30. Recently I decided to follow a tutorial on here to enable the sprint spark network band on my phone (even though spark is not in my area). Going into *#*#3282#*#* I went into LTE, Edit, and after I changed the priorities of the 3 bands so that band 41 was the only one set, I hit back to reboot my phone and tested my speed. It was at about 6.00 mbps. I didn't know what was going on but I thought maybe i "fixed" something and that now I could enjoy faster internet. Well, after a bunch of speedtests, it eventually went back down to 0.30 mpbs.
Fast forward to now. Essentially whenever my data speeds are slow (0.30ish mbps) I simply go into *#*#3282#*#* > LTE > Edit > I don't need to actually edit anything, I just hit back to reboot my phone, and I get fast speeds again, the highest I have gotten was 12 mpbs, and sometimes the fast speeds stay for hours, and sometimes only minutes. My uneducated guess is that when i do this reboot, my phone is switching towers or something and is connecting to one with less traffic and faster speeds. Not sure, but something is obviously happening.
Does anyone have any idea what is happening and why I see such an increase in speed whenever I reboot my phone from the LTE > Edit page? Am I being throttled? Is there anything I can do to make these fast speeds "stick?"
As of now I simply do this little LTE > Edit page reboot before I decide to stream something or use data on my phone. But I would like to figure out how to have fast speeds all the time.
