Connection issues after installing Roms - Sprint Galaxy S 5 Q&A, Help & Troubleshooting

I tried a couple roms and I liked them but it lokks like I have a lot more 3g connection now. Before using roms I had almost a constant lte/4g/spark connection. Is there a way to resolve this issue? Did I do something wrong?

Unfortunately, that's a common problem with ROMs.

I would verify if anything in your APNs changed.

[Q] AOKP and wifi hotspot

Whenever I use AOKP's built in free hotspot with Windows it connects but with limited connectivity. Thus making it pretty much useless lol. Tried it in Ubuntu as well but it just wouldn't connect altogether. Anyone else experience this issue? If so what is the fix?

I think I read it had to do with security. Try using it as an unsecured access point.

Network mode problems after cm10 and sim switch

I'm using an infuse 4g with JB 4.2.1 cm ROM. I unlocked my phone and put in a T-Mobile prepaid sim.
I'm supposed to have 4g consistently but I'm getting 2g(edge), 3g(umts) and on very rare occasions I get 3g(HSDPA)... Its approximately 70%-%20-%10, respectively. And these changes are all happening in the same household. No tower switching.
I only have the option to switch on 2g only in my network mode settings on cm10... APN settings are correct and all T-Mobile can say is that I won't get 4g if the tower doesn't support it..
Are there any possible solutions to obtain 4g at all?
If so, how do I keep it on all the time?
Do I need to install a new modem?
If so, which?
Any comments and/or answers would be greatly appreciated.
Thank you.

Using Uckl2 at the moment. FYI.
Also, I know the modem is for WiFi but does it affect carrier data? If not what can I change to affect my data connection?
Sent from my SGH-I997 using xda app-developers app
I always thought the opposite. I thought modems were only for mobile data. But does switching modems help?
Sent from my SGH-I997 using xda app-developers app
Could increase or decrease your signal and rate at which data is downloaded and uploaded depending on your modem of choice. Battery life is also affected minimally (usually).
Sent from my SGH-I997 using xda app-developers app
Hmm, didn't know that... Well thanks for the lesson but have you tried switching modems?
Sent from my SGH-I997 using xda app-developers app
I switched through a couple and uckl2 seems pretty stable but no change on carrier network service.. I want to put on kl3 but I can't find the download.. Not too many options for my phone though.. That I know of.

It might just be your location.
Sent from my SGH-I997 using xda app-developers app
Since I changed to cm10 and switched to T-Mobile sim I have yet to have 4g. Tried where I'm at now and up to 70 miles from here... Very weird. I can't tell if its T-Mobile or the ROM.

Have you had it before on the same phone? Have you tried using another 4g phone?
Sent from my SGH-I997 using xda app-developers app
Yeah I had 4g on it before, on att and on metro. Both while using stock Froyo rom and GB aeon rom.

Weird, it sounds like its the network then
Sent from my SGH-I997 using xda app-developers app
Yeah that's what I'm thinking but when I called T-Mobile, they said that they cannot diagnose a non-tmobile phone. The only info that they can give me is that they assume its my location and possibly the modem but they cannot guarantee switching modems will work. Doubt they hack phones though, Lol
Sent from my SGH-I997 using xda app-developers app
from my recollection..not from experience:
T-mobile or networks other than AT&T will only give you: edge or 3g.
No 4g or hpsa+
to get better than 3g, you need to be on AT&T
When the phone is on "H" I ran a speed test and its pushing 5 to 7 mb download speed. Is that close to 4g?
Any advice on how to stabilize the network?

if you are in an urban area and close to a tower, some are reporting 8+
look back in the old threads..i recalled these discussed toward the beginning of device release..jun jul aug 2011 era
Appreciate it, thanks!

[Q] APN settings for Simple Mobile

Tried searching and could not find any settings that worked for me. On my N4 I used what is on the simple mobile site and I had internet but no mms. Now I cant even seem to get the internet to work. I have tried different settings I found online but none seem to work for my N5. Any help would be greatly appreciated. Thank you
Confirmed working on simple mobile.
Make sure you select simple mobile network from available network.

3g lock with native hotspot mod

Sent from my SM-G900P using XDA Free mobile app
I recent rooted/unlocked native hotspot on S5. Worked great then LTE/spark disappeared and now its stuck on 3g. However I go 15 miles away and it works. Then when I get near my house it switches back to 3g. Is this a network tower issue /update or a root issue? Please help.

Try updating prl or disabling 3g band

Just updated the mod, it no longer modifies the APN, try it out and see if it helps.

Anyone's YouTube app been buffering like crazy on mobile data?

This started for me about two days ago. I've uninstalled, cleared cache and data. I finally got it working again by reverting back to the stock pre-installed app. Anyone know where to get the version before this most recent update?

It's also been happening to me over Wi-Fi as well.

I've had this happen to me as well. Could never figure out what it was but eventually the problem went away. My only theory is Verizon throttling me for using to much data but I don't know cause I average about 30-40gigs a month and it doesn't happen every month.
Getting the same over data

Did for me.
I tried a few older YouTube apks and I am happy with 5.3.23. Everything after that buffers like crazy for me.
