Cm12 official: bad data connection - Galaxy Note II Q&A, Help & Troubleshooting

Hello everybody, I'm on CM12 since a few days (upgrading to the latest nightly on a daily basis) and keep having data connection problems. LTE or 3g connection in general are very unstable, they stay connected for seconds or few minutes and then they stop working. It seems to be an unsolved problem. Does anyone else experiencing the same and found a fix? It is really frustrating.
Thanks!

Cyanogenmod 7.2 wifi issues

Im having issues with my wifi signal on cm7.2 When I'm in my computer room perfect signal as soon as I move away from router signal drops to two bars. I was hoping wifi signal issues were going to get fixed in 7.2 had the same issue in 7.1. Anyone having similar issues? On Glite 2.0.1 I had perfect signal all the time. I'm using a Dual antena 802.11n router.

[Q] Radio 4G->3G locks on toroplus CM11 nightly

Put on CM11 Nightly (20131218) and I am having issues with handoffs from 4G back to 3G (although 3G to 4G seems to be fine). I can turn off radio and back on and everything is fine, but was wondering if anyone had a better idea about this?

official or unofficial build?
what gapps did you choose?
did you dirty flash or do clean install?

Official nightly
GApps 20131208
Clean flash (format /system, dalvik, cache, and data)
I've since gone back to 10.1 since it seems to be the most stable for data handoffs, but I would love to get KitKat going again.

I'm seeing the same problem with the latest snapshot (cm-11-20140104-SNAPSHOT-M2-toroplus.zip). I plan to switch to CM 10.1 for now, as well, since 10.2 still has known "Issues between 4G and 3G switching".
(wiki.cyanogenmod.org/w/Known_Issues_page_for_toroplus)
Any updates would be appreciated.

I updated from CM11 Snapshot M2 to the recently posted Snapshot M3. The 3G/4G handoff problems that I was having in M2 appear to have been fixed in M3. However, the (stock) portable wifi hotspot function isn't working properly for me now with M3.
After some additional testing I've found out that my signal cuts out and has problems reconnecting after activating the portable wifi hotspot (similar to the previous 3G/4G handoff problems). And the my other devices can connect to the portable hotspot but they do not get an internet connection. It appears that turning off the portable wifi hotspot and then toggling data may reset the data connection.
Is anyone else experiencing the same behavior?

I've been having all sorts of data issues lately, even worse I think with M3. But, I haven't cleaned flashed in a while. I hadn't thought to try toggling hotspot--I'll have to try that next time I can't get any data (3g or 4g). Over the weekend I had to hotspot my phone a bunch and since lte doesn't yet reach my house I had to hotspot 3g and that was working just fine. I'd be interested though, if you're consistently having good 4g data or if it was just a momentary fluke for a day. It seems like some days I've had no issues with 4g and other days it's been a bear where I struggle to even get 3g.

yotvb531, your suspicions were right... After 1 day of flawless data handling on CM 11 Snapshot M3, I experienced a hiccup during a 3G/4G handoff. Soon after, the data handoff problems became routine like they were with Snapshot M2 (perhaps worse). Although toggling the data connection would get the network to reconnect, the data connection problems occurred often enough to make me revert back to CM 10.1.3 a day or two later.
I'm now anxiously awaiting the next CM 11 Snapshot, hoping the data connection problems will be fixed.

After not being able to pick up 4G from the snapshot on, and hearing from others that they had 0 issues on a clean flash, I finally spent the 5 hours to clean flash my phone (I also formatted the sdcard while I was at it because I hadn't done that either in a very long time).
Happy to report that ever since then (12 days and counting) things have been very smooth. I've had issues only twice, but based on the behavior I'm pretty sure they are attributed to cell tower maintenance and not my phone freaking out...mainly because it didn't matter what I tried and then hours later after I had given up messing with settings everything started working again and was then fine for a week afterwards...and also after that outage the data speeds went from 1 Mbps to 8 Mbps.
Not saying a clean flash will fix everyone's problems, but it definitely did wonders for me...fingers crossed that when I finally decide to move on from the 2/13 nightly everything will continue smoothly.
There I went jinxing myself! I had to toggle airplane today after leaving work to get 4g to pick up. Was stuck on 3g EVDO. Toggling airplane mode got it to switch over to eHRPD which then allowed it to pick up the 4g. So maybe the hand-offs aren't perfect, but act fine most of the time--in my situations.
That same behavior happened once before on this same nightly (2/13) and I chalked it up as tower maintenance. That was in addition to the other time I mentioned where speeds jumped from 1->8 Mbps and I didn't have to do anything for the lte to return. I think that one was actual tower maintenance; just the other one wasn't...and it happened again today...twice in 14 days isn't too bad but it's definitely not perfect.

If I could get CM 11 to behave like that I'd switch right back to it. My problem wasn't that it would get stuck on 3G, it's that it would get stuck and not have any data connection until I either toggled data (e.g. airplane mode) or restarted. This would happen multiple times per day.
While I always clean flash, I never format my SD card. I assume this step has to be done separately from flashing, correct? Is it a best practice, or can just the Android folder (any others?) be deleted?

I did my internal storage wipe at the same time under advanced wipe in twrp (cache, dalvik, data, internal storage). I don't think it has to be done very often...I hadn't ever done it since the toroplus phone first came out so I had a lot of garbage and hierarchical messes all over the place (the 0 folder in 4.2 that was created...).
I doubt wiping the internal storage has any effect on the functioning of the data hand-offs; but I just don't know either.

Network issues cm12.1

Hi guys,
So I'm currently on the 20150507 cm12.1-nightly and I'm having annoying network issues. I can't seem to get a stronger internet connection than EDGE. I used to have 4G/LTE speeds, but since I flashed cm12 this just disappeared.
Anyone else having this issue? Or does anyone know how to solve this problem?
Any help is appreciated
update to latest and see....

Question WiFi Issue

Hello. I bought Poco F3 about a month back and currently I am on miui13 global ROM. My phone WiFi keeps getting disconnected and WiFi is slow. There is no problems with the WiFi zone or router. This issue was there with MIUI 12 as well. Of course issue is better with MIUI 13. However it's still there. Is anyone else having WiFi issues? Thanks in advance
Have you try reset network?
