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?

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.

Well I have been having some major wifi issues as off late. I have wiped and reinstalled various roms and nothing has seemed to fix. Right now I am running cm nightlies.
My wifi is EXTREMELY slow. At my house I get 12M/1M on my computer (which is wireless) and on my phone I can get anywhere from 500-2500kb down and from 0-750 up. When doing speedtests it freezes on both the upload and download and sometimes will not finish upload test and give me latency of 999.
I have used my wifi in various locations (home, work, hospital) with the same result: my 3g speeds are way better than my wifi.
What are some things that I can do to attempt to resolve this? If it matters my kernel is: 2.6.34.5-cyanogenmod.
My wife is having issues with her data connection on her phone-
The phone aspect of the Captivate Glide works fine, but there are times where she is trying to us data (to check emails..etc..) and phone states she does not have a data connection. Also, her 4g icon disappears from the screen. Only solution (which she completely hates) is restarting the phone. Have had several android phones, but this is a first for me-
Currently running OsiMood.0122.RUXKJ5 Android 2.3.5
different ROM, same issue
so i updated my wife's phone to thegreatergood's literom (version .6), and I'm still having issues with the phone sporadically losing it's data connection. my wife is still able to make phone calls, however, all texting and data remains off. I have to restart the phone in order to restore data/text...any ideas?

I have seen this as well once or twice in the past as well. I am also on the greater good's literom 6 and liteKernel v4. Rebooting does fix it. Not sure what is causing it as well. I think it happened when I had low reception then all of sudden no reception all together. Wonder if you have no reception for too long can trigger this? Rebooted and wen back to having low reception but at least some. My work has a lot of interference so I rarely get good reception at my desk, often I see the E sign for edge network and when I see that I know it is going to be Dog slow.
I just flashed CM10.2.0 from 10.1.3. I performed a wipe of data and cache so I'd consider is a clean flash. Since doing this, the phone will usually not switch to 3G/4G over the air when I leave WiFi. If I reboot the phone, it immediately acquires 3G/4G. This was never an issue with the previous ROM.
I see a lot of posts about these kinds of issues with the current nightlies but can anyone offer suggestions for a fix for the CM10.2.0?
I'm hoping that I just have the wrong radios flashed for 10.2.0/4.3.1 - I'm on FK01/FK02 and on Verizon so CDMA...

wow, would have expected to at least get some replies on this given this is a topic that is going hot and heavy regarding CM's latest nightlies.
Bottom line, I did a clean flash and the phone now has a terrible time doing any sort of handoff to cellular data from WiFi. Sometimes I'll see a 3G or 4G indicator and still not get any data, sometimes I don't get any sort of 3g/4G indicator and just see signal bars.
I've even had the phone refuse to make a call - it performs everything like it is making the call but nothing, just silence. I've never had any of these issues before so I'm going to have to assume something in CM10.2 is the culprit.
Going back to 10.1.3 I guess even though I do like some of the features of 10.2.
So I've been having this problem for several months now...
1. When I go into the testing menu (*#*#4636#*#*) it currently says LTE/CDMA (auto PRL)
a. When I switch on LTE from the notification pulldown I cannot get a data signal, however voice calls still work. I can leave searching for 20+ mins. for a signal, it never finds one.
b. When I switch off LTE I am able to get a 3g data connection, and voice calls continue to work
2. When I go into the testing menu (*#*#4636#*#*) and switch to "LTE Only" I am able to get a 4g signal, but no voice calls or sms (as expected),.
I've tried a the 3 most recent radio's. I'e gotten 2 new SIM cards. I've tried clean installs of CM. I haven't tried other ROM's, although I'd be open to suggestions if people have no data issues (I like CM a lot though).
Any one else experiencing anything like this?
Thanks for your help!

I've experienced the same problem on newer nightlies, M5 and M6. I formatted /data, /cache, and /system, then install M4. data + voice work right away.
Try switching to CM11 M4.
I upgraded to M6 (then tried M5 after it didn't work) due to bluetooth issues on M4; specifically, none of the advanced features of bluetooth, such as the ability to sync my text/voicemail notifications and display artist/title info on my dash, didn't work with my car. But I'd rather have reliable mobile data service on M4 with crappy bluetooth support than unusable mobile data service on M6 with great bluetooth support.
Edit: this is a toroplus phone on Sprint, btw.

This seemed to work for me. Thanks for the help!
I work out in the middle of nowhere, there is one cell tower and usually I get slightly more than half bars. My connection isn't great as it is.
When I updated to 4.1.0 tho I noticed I frequently had to reset my data connection (toggle airplane mode on and off) to get data to work faster than a snails pace. After a couple days of this I downgraded my modem back to 4.0.3 and my data works again as normal.
I also had my pebble smartwatch lose connection for the first time, repeatedly, on 4.1.0. on 4.0.3 I never had this problem.
Has anyone else experienced these issues​? I know 4.1.0 was supposed to improve wifi and bluetooth but I haven't seen much criticism, maybe it's just me? I will have to test again when I'm in the city again.
Edit:
For those having modem issues there is a list of flashable modems here: https://forum.xda-developers.com/oneplus-3/how-to/radio-modem-collection-flashable-zips-t3468628

Same thing as you op downgraded modem to the same you did its more stable but still drops out
