flashed to cm9 alpha 6, get grey 3g bars no data - Samsung Epic 4G Touch

When I was on stock I was always on 3g. Now that I flashed to cm9a6, I've been waking up to my phone with grey 3g bars. I flip to airplane mode and back to fix it and finally get my emails but its a real pain in the ass.
I looked into it, but saw posts from march, wondering if anyone had a fix or if this is just a bug.

Bug but, there are newer nightlies to flash than a6... Google chris41g to find his server with nightlies, otherwise go ask in the thread for more specifics

Why are you on alpha 6? Lol that is the question. Chris41g is knocking out RC quality builds that you need to be flashing if you want cm9. Get on it

I was having issues yesterday with my 3g not working. I am on a newer build of cm9. I just think it was a virgin mobile service thing because my 3g is fine now.

Did you try making sure you had data roaming enabled in your settings?

Bad service on my Evo....

I never have more than one bar of service on my evo, at best two bars. My reception is -84 dBm. I live in Houston so the area is not the problem. Everything else is working great. Any advice on fixing? Though I would try here before calling sprint.

Did you update the radio recently?
Yeah I updated my radios and everything else from here.

If that's when it started you should revert back to a previous version.
Its also true that after you update a radio you should update your prl and data profile
No this has been going on for a while now, I was hoping the radios would help and they did for 3g speed. Just my service blows. What is considered a good dBm?

You mean it's always this bad with that phone or it's always this bad no matter which Sprint phone you have?
I have a HTC evo 4g, I think I noticed right after I rooted it last November. Running cm7 rom.

Rooting won't do anything related to that...
CM7 tends to be more accurate on displaying your real reception.
You may just be at the edge of a tower.
In my settings, (Mobile network state: disconnected). Could that be it?

you wanna talk about bad service!!
I just pray to God none of you are from west Michigan... our network has been over its capacity since December 22, 2010.. I know this cause I work at a service and repair store, makes me want to hurt a child.
texts come in hours/days late and if they do come in.. it comes in 5+ times... calls take 45-50 seconds to connect, voicemails come in DAYS later, you will have a missed call and your phone never rang.. internet is almost impossible. makes me hate my job!!!

I repliex in your other thread so check there.
We actually don't have a UVALH1, that's on a different carrier I think. Previous radio was UVALG1, so I'm assuming you're on the latest already.
I'm thinking its a network issue since you haven't done anything in a few days and it was working before.
Call tmobile and ask if they're having problems on their end.

4g lte not working

I am running the latest cm10 nightly and I haven't been able to connect to 4g lte for the last week or two. Is anyone else having this problem? Has anyone found a solution?
Sent from my SPH-L710 using xda premium
Which market are you in? There's a chance that the tower was only on for testing and has since been turned off. There's also a chance that another tower closer to you is currently being upgraded, so the phone is trying to connect to that tower's LTE, getting rejected, and falling back to 3G. That's what's happening to me, and it's frustrating because I had a steady 4G signal for a week and a half, then one day, it refused to stay connected to 4G for longer than a minute. Now, I just have to wait for them to finish the new tower.
The reason could be just about anything depending on your market.
I am in the Atlanta market which has been officially announced. Friends that live nearby have not been having this problem on stock ux software. I was wondering if cm10 has a big or something?

Actually, it has a couple LTE bugs. CM10 doesn't currently handle 3G/4G handoffs properly, so that could be part of the issue, but it holds a 4G connection fine if the signal is strong enough, at least from my experience. Another bug is that it will just stop making connections, and you have to wipe data to fix it. Have you tried toggling airplane mode? If that doesn't work, make a nandroid and try a clean install of CM10. I had to do that recently because it completely stopped connecting to 4G and barely connected to 3G. As soon as I booted up, 4G was back (didn't last long, but I explained that in my other post). If wiping data doesn't work, flash to TW and see if the problem persists. If it still doesn't connect, then you may have a hardware issue, but I think that's unlikely since it was working for you before. You never know, though.
Keep in mind, even though Atlanta's been officially launched, it's only about one third complete, so lots of towers are still being upgraded. It's possible you're facing the second issue in my first post, like I am. If so, then just concentrate on how much better it'll be when the new tower is finished.

Happened to me several times. The best thing you can do is make a nandroid once you get your favorite AOSP rom set up to your liking, and restore to it once LTE stops working. I tried to get myself to go to TW but its just so slow
What is TW?

I have a similar issue. If i go into settings, about phone, and status I pick up LTE:13, but I get no connection or IP address so I have to change over to 3g. Is this a known issue, and if so is it being addressed? I am currently running nightly 10-14-2012 if it helps. Thanks
Edit: I've tried TW and it works just fine there. 14 down and 6 up.
Its likely to do with cm10. And the handoff issue like it was explained a few posts back. I love cm10 but data would work if u was lucky for 2 hours out of the whole day. So I'm on the leaked lih build. Just gotta wait patiently for the great devs to figure it out.

[Q] Extremely weak wifi

Hi guys.
I don't know if its my phone or if this is the way the phone is meant to be, I have an extremely weak wifi signal. I am literally right next door to my router and I only get 3/4 bars for signal strength. As soon as I go up to the second floor, I get nothing at all unless I'm directly above my router. This is extremely frustrating at the moment. I decided to lurk around the forum to see if installing a custom rom would help and I ended up installing Jedi Invasion 2; it did not help at all.
It's just so frustrating that I have to use my mobile internet when I'm in bed instead of using my home internet. I don't understand this at all. Why is it so weak? Does anyone else have this problem?
Thank you.
Im with you on this......im staying tuned..

Have you tried updating your modem to the latest version that was just released?
My modem is perfectly fine. I just dont understand how my old crappy blackberry had a better and stronger connection than my s3.
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
I found the Wi-Fi performance increased a fair bit when I upgraded to 4.1.1. I can go a fair ways in my house before dropping bars. Wish I had run WiFi Analyzer before the upgrade so that I could actually compare RSSI.
Depends on the router freq. 2.4ghz and 5ghz. 5ghz can cause crappy WiFi strength issues. Change the settings around to 2.4 only and see what happens.

My router does not support dual band. Like I said earlier, my blackberry has a stable connection while my s3 struggles.

I had the same problem in 4.0.4 ICS but now on 4.1 JB it is working perfect. Before on ICS I had like 3-4 bars when I was 2ft away from the router. Now on JB I have full 5 stable bars no less with higher distance.

The modem he is talking about is a radio for the phone. Not the modem that connects you to the internet through your ISP.
Oh. Im still relatively new to this device so I never knew. How do I update the modem?

Simultaneous voice and data problem

I'm running CM 10 on my AT&T S3. I'm in an LTE area and have LTE coverage. I also would have strong HSPA coverage as well.
My issue is, when I'm on a call, I have no internet connection. There is no 4G/H/3G icon at all by the signal bars (which are full). And when I try to go to a page it says No connection.
Is this an issue with CM10? Anyway I can fix this? I can't seem to remember if the issue was present on stock.
Same here. It worked on stock att
