Very frustrating issue seems to have developed for me over the past month or two in which MMS cannot be sent or received while I'm connected to WiFi. If I disconnect and switch over to LTE, MMS messages are received almost immediately and I can send them with no problem.
This is on AT&T using CM11 nightly 20140913. I used many nightlies prior to that over the summer and cannot recall when the issue developed, or if it began after a certain nightly.
I've seen this very issue (MMS problems while WiFi is connected) discussed sporadically for many other devices. Some blame it on Hangouts, but I have tried AOSP Messaging, chompSMS, and others, and it doesn't change anything. I'm *positive* that my APN is set properly (mmsc.mobile.att.net, proxy.mobile.att.net, port 80); it's also set both in the main system menu and manually in each SMS app I've tried. I can only conclude it's either an issue with CM11 or a carrier problem that has recently developed.
It's worth noting that chompSMS has a menu option that specifically forces a switchover from WiFi to mobile data when MMS is being sent/received. Even checking that option doesn't solve my problem. This makes me wonder if, perhaps, it's a ROM issue wherein the WiFi cannot be disconnected properly for this purpose? Has anyone else noticed this behavior on recent CM11 nightlies?
So I just did a nandroid backup and then flashed nightly 20141016. Sure enough, the newer nightly solves the MMS issue. However, WiFi hotspot is broken, as it has been for me on nightlies for several weeks now (thus, why I'm still running a month-old one). Too bad I don't have any backups from before the MMS bug appeared.
EDIT: Apparently this was a CM11 bug fixed on or around the 20140917 nightly. Where might I be able to find that nightly to give it a shot? At some point after 20140913, WiFi hotspot was broken, but hopefully there's a sweet spot in there somewhere. I've verified that hotspot is kaput on the M11 release. Really hoping to avoid a factory reset/clean flash if possible right now.

I am a Big supporter of the CM Team and how they were able to give New Life to my old Epic 4G. Great job!
The problem I am having started when I moved from using CM9 to CM10 After doing a Factory Reset "clean" install... I primary use my Epic 4G as a Wifi Hotspot for my Xoom WIFI tablet which is using Team EOS3 Nightly ROMs. Now I never had ANY WiFi (speed) related problems using the CM9 version as long as I had a good signal. When I upgraded to CM10 I was able to enable the WiFi HotSpot but web browsing was extremely slow and had timeout issues to the point where it is completely frustrating and unusable. The issues due not seem to be depended on the phone's signal strength and I have not been able to resolve the problem. Has anyone experienced a similar issue?
Thank you in advance,
I have something similar. It seem to have began after the 11/19 nightly for me. The range of my connection seem to have decreased. Or if it is connected with -70 and below on Wifi Analyzer, it may get not data or very slow speeds, and timeout issues.
I have not seen any kernel changes from bbelos, so maybe it is something else in the CM nightly changes?
I am currently on 11/29 nightly, stock kernel.

I am on the nightly from 12/3, and I can't get the wifi tether to work regardless of what I try (have set it up with open, WPA2, used Auto and Device specific for Epic 4G) - nothing seems to get it to work.
Is there another modem or anything else I should try? I tried to post on the CM10 forum, but as I'm new, I'm not allowed to.

Don't use an app, there is an option in settings>more>Tethering & portable hotspot
I can't even get it to work with the built in option. It acts like there is no internet.
At first it seemed like an issue with the phone app in the Euroskank cyanogenmod 10.2 builds constantly force closing, causing a temporary loss in cellular connectivity as a result. But now I'm experiencing this issue with non-cyanogenmod ROMs as well. I never had this issue with 4.2.2 ROMs, so I'm pretty it isn't a hardware issue I'm experiencing. Basically, the phone app crashes periodically, even when the phone is idle, and sometimes it causes me not to be able to receive texts for hours at a time (which for me is unusual due to the fact that I receive hundreds of them throughout the day from Twitter). Any idea what might be causing this and how I might be able to fix it?

Me too after flashing with PA ROM/Faux Kernel, not able to send/receive SMSs. Using 4.3
I can send but i cant receive, but if i send it, the one that has to get it doesn't get it..
Hi all,
It has been a while since I've used the phone, and my fiancee wants to use it, so I fired it up again. However, I have noticed a problem, which I've actually always had, but which annoys her - MMS is not working.
Android versions:
I'm using the latest unofficial CM10 build floating around. I have previously also tried Jellytime, but it was even worse (see below).
Problem:
Whenever she tries to send an MMS, it basically knocks out data. I have googled, and seen that many others have had this problem. Data connection basically drops, the bar goes grey, and it won't return until i re-register the phone on the network, reboot, goes to flightmode or back, etc. Internet works, as long as I don't send any MMS-messages. I am unable to received them as well.
I have tried:
- googling my ass off,
- the official APN settings (one for web, one for mms),
- resetting APNs,
- default,supl + default,supl,mms as types,
- combining into one APN,
- various APN apps,
- reinstalling ROM,
- other ROM builds (Jellytime, was even worse, could only get data connection, when wifi was on and connected to a network, after a while i could then disable wifi and it would keep the data connection for a few hours).
- lots of other stuff...
Any ideas welcome.
Have you tried going back to stock?

Going back to android 2.x stock is not an option, sadly.
I do know that MMS worked fine when I got the phone some years ago. On a different network provider, though.
CM 9 and higher have issues with MMS as far as I know.
CM7 hasn't got any issues. And I believe each thread as a fix

I have tried to research but cannot find anything specific to my problem. I know there are a number of guides that show how to flash a Sprint Galaxy Nexus to Cricket, but that's not exactly relevant here and I'm not familiar (or smart) enough to make sense of what may have caused my problem. So I'm resorting to XDA for help.
The problem: my Sprint GNex (toroplus) has significant MMS problems. Anytime I flash a ROM, the MMSC URL is reset back to Cricket (http://mms.mycricket.com/servlets/mms]). Problems are improved but still exist when I use CDMA Tools to change the URL to Sprint (http://mms.sprintpcs.com).
ROM: Cyanogenmod 10.1.3
Recovery: TWRP 2.7.1.0
Radios: GJ04 (CDMA & LTE)
Stock messaging app
Does anyone know what may be causing this? Please help! Thanks
Additional information:
After updating my MMSC URL with CDMA Tools, my MMS still don't always send properly, and if they do send they're sometimes very delayed (e.g. I recently sent 3 pics to a friend, 2 went through properly, one went through the following day). Or, I sometimes don't receive MMS at all, and I've noticed it may happen with any of my contacts on occasion, but some specific contacts I'll never receive MMS from (an alert may show up from that user along with another SMS/MMS alert, but no message from that user appears in the conversation list).
The phone is indeed activated on Sprint. Calling, data, and SMS all work fine. I'm currently on Cyanogenmod 10.1.3, but I previously was on CM 10.2, CM 10.2.1, and a few different CM 11 Snapshots (which is when I first began noticing significant MMS problems), not necessarily in that order. I also tried flashing another ROM (to see if this could possibly be a CM related problem), but the MMSC URL also reverted back to Cricket when I flashed Omnirom. So this doesn't appear to be ROM specific.
I flashed the radios from the following thread, and have been on GJ04 for a long time. I cannot recall if flashing the radios was around the same time I first noticed MMS problems. But given that no one on that thread has complained about Sprint MMS problems, my guess is this isn't the cause.
http://forum.xda-developers.com/galaxy-nexus/sprint-develop/sprint-radio-collection-t2195481
I bought my Toroplus used, although I believe it was (Sprint) stock at the time. I activated it with Sprint without any problems. I rooted it and do not recall any problems with MMS for months.
Thanks again
Hello all,
I have tried out a variety of ROMs on my Z1 Compact (D5503), but unfortunately there is an issue with every Lollipop-based ROM that I've flashed. I can connect to WPA2 Personal networks just fine, but attempting to connect to a WPA2 Enterprise network takes much, much longer than usual. Not only this, but the Wi-Fi will disable itself when it disconnects, and when [re-]enabling Wi-Fi in Settings, the Settings app will freeze with "Turning on wi-fi", seemingly indefinitely. Sometimes it will connect again and the app will continue responding, sometimes it won't, but this only happens with known WPA2 Enterprise networks in range. Using the quick toggle has no effect either.
Lollipop ROMs I have tried include Dirty Unicorns, CyanogenMod, Resurrection Remix, SlimLP and CyanHacker. It seems it is common to any Lollipop-based ROM I flash, but I have no clue as to what is going on. Nothing seems to appear in the Logcat either.
Does anybody else have this issue, or know how to solve this? Some searching has led me to similar issues for people on Nexus devices (https://code.google.com/p/android/issues/detail?id=80028 and http://forum.xda-developers.com/nexus-4/help/lollipop-wifi-issues-takes-long-time-to-t2941686), with no solutions.
For now, I unfortunately had to downgrade to KitKat -- every KitKat ROM (stock and AOSP) has absolutely no issue with connecting to these networks quickly, but it seems that most developers have moved to Lollipop.
I can confirm that. I have the same problem in our company network. But could it be, this problem is related to the MAC address problem? (same MAC address on all phones using cm12)
And here I thought I was the only one! It is a relief to hear that I am not the only one with this problem, because it means that it probably has a solution.
Well, I have tested out both Resurrection Remix (CM based) and Dirty Unicorns (AOSP based), and they both have the same MAC address. The bug seems to be described at https://jira.cyanogenmod.org/browse/NIGHTLIES-659 and http://wiki.cyanogenmod.org/w/Known_Issues_page_for_amami and there seems to be a fix suggested at http://forum.xda-developers.com/xperia-z2-tablet/help/change-mac-adress-permanently-cm12-t3038146 although it seems like it is not just limited to CM.
I will test out one of these ROMs tomorrow with a modified MAC address to see whether the fix helps at all.
I didn't try it yet because I often try new nightlys and don't want to copy over the MAC address file everytime again. But it would be interresting to know if this causes the problem. Actually I just disable wifi when I'm at work. Please share your test results then.
Well I tried it with Dirty Unicorns unofficial ROM today, and I managed to change my MAC address by editing the file /system/etc/firmware/wlan/prima/(something).ini. This was confirmed by the "About Phone" dialog in the Settings, unfortunately it doesn't seem to help the connection to wi-fi, which suffers the same issues. Deleting wi-fi networks seems impossible too.
Too bad. My hope is that the upcoming release of Sonys official Lollipop ROM will help to fix this and other issues in our open source versions.
WiFI works perfectly in the last unofficial CM nightly from OmarEinea, unfortunately there are a few other issues that have since been fixed (A2DP is a bit dodgy), and it's missing whatever CM features have been implemented in the past couple of months. It shows that WPA2 Enterprise can work though.

I tried out the latest nightly (2015/03/22) earlier today and while an initial connect works, subsequent connections can fail and lock up Settings indefinitely. So I suspect it is an edge case with Lollipop's wifi settings and certain networks, or devices.
