Dear XDA HTC Desire C Users,
Let me start off by saying I know that this question has been asked before. I've lurked these forums since 2010, I've flashed many devices with many custom roms and kernels. I just want to know what the deal with CyanogenMod is.
I've recently come into possession of a HTC Desire C. It's a great little phone, not what I was expecting at all when I bought it off a bloke at work for £30. Started it up and it was bogged down with all the normal crap you get when someone has a lock stocked phone. Decided to check out XDA once again, and found that there was a port of my favourite rom; CyanogenMod.
I've previously used CM on my Galaxy Europa, Galaxy S 3, Galaxy S4, Nexus 7 and Xperia Play. Using my phone as a WiFi Hotspot/for Wifi Tethering (however you want to say it) was only ever a problem on the Xperia Play (and possibly the Nexus 7, I haven't actually tried). The checkbox would tick, the writing would say "Turning on wireless..." and then that would be it. It would never complete the action. USB tethering has never been an issue, and I never really needed wireless tethering until I got a Nexus 7 around Xmas. Funnily enough, my Xperia Play broke at the same time, and I went back to using the old Europa (CM7, working wifi tether).
Now I've loaded this Desire C up with CM10 with NOPE Kernel v2.6, tried this wifi fix that a lot of people seem to enjoy linking to (granted, it does make WiFi work, but not tethering). Some other suggestions were to use Barnacle WiFi Tethering app, but it creates an ad-hoc connection which a Nexus 7 can't connect to.
I guess it's really a few questions, which I can summarise here for those of you unwilling to read the above text :
- Why does CM have working WiFi hotspot/tether settings on most of my previous devices and not the HTC Desire C?
- Has anyone actually ever got their Desire C to tether with CM10 (any version for the HTC Desire C)? If so, how?
- Are all JellyBean roms having this issue?
- I've read that Sense based ROMs are the only ones that have functional wifi tethering settings. If so, that means I'd have to use an ICS ROM to be able to use wifi tethering?
- Am I doing something wrong? The past few years I've had to relearn how to do all this stuff to a different device each time, I may have missed something that's more prevalent to someone who is immersed in this regularly. My process was as follows -
1) Downloaded CM10 Build 3, TWRP 2.4.2.0, GApps & Nope Kernel v 2.6 (700mhz)
2) Flashed TWRP 2.4.2.0 as recovery (fastboot flash boot recovery.img)
3) Rebooted into Recovery
4) Backed up, wiped & flashed (Factory Reset, Cache, Dalvik, System)
5) Installed CM10 and Gapps (install .zip from sd)
6) Rebooted to Bootloader, flashed NOPE Kernel (fastboot flash boot boot.img)
7) Rebooted to Recovery, wiped Cache/Dalvik Cache
8) Started phone, set up, tried WiFi Tethering.....nothing happened.
As far as I can see, I've probably missed one detail that is affecting the entire process. I assumed that since this was cute_princes v3 marked as "wifi fix", that I wouldn't have to put the folder I linked to earlier onto my phone (the file contatining p2p_supplicant_overlay, wpa_supplicant and wpa_supplicant_overlay).
To confirm, I tried the boot.img that came with CM10, it was some form of Prometheus and that didn't work either. I have tried MiniCM10 as well, same results there. I have flashed NOPE Kernel v2.6 on both CM10 and MiniCM10, to no avail. I also tried the boot.img that was packed with MiniCM10, same result.
Sorry for the long post, but I feel that it's better to over-explain yourself, rather than leaving people guessing. If anyone could shed some light onto this, I'd be very grateful. It's something that made me curious enough to post after 4 years of silence and lurking in the background. The fact that I've managed to root and flash all the previous devices I've owned without ever having to make a post shows that all the information is available to me on this site, and that XDA is such a great place that this information is readily available for me. But in this case, I can't find what I need, so I call to you for help.
Thanks in advance,
Gordon Freeman
It's a cm10 bug.... I don't know if too many people have looked into this....

That's the answer that I hear the most, and I never hear anything more than that. What kind of bug prevents it on certain phones? Why do Sense roms (apparently) have working wifi hotspot?
All my other questions are still open, plus a lot more for discussion. I am only a couple of months away from buying a Nexus 5 anyway, but I need this phone to wifi hotspot in the meanwhile.
Sense ROMs have working Wi-Fi hotspot as they are sort of a modified stock ROM....

So you're saying that I have to use an Ice Cream Sandwich ROM if I want to be able to use wireless hotspot/tethering? I'm assuming that if there are no JellyBean ROMs that have working wifi tethering/hotspot, then it has something to do with the phones hardware being unable to work with a newer Android OS. But I'm pretty sure I've read people having success with tethering on JB ROMs.
Maybe someone could point me in the direction of having CM10/any JB ROM with working wifi hotspot/tethering, I'd be grateful.
THIS has been such a deal-breaker for me with the CM10 ROMs. But... Fear not!
The recent MiniCM10 by warrior1208 has fully functional USB and WiFi hotspot tethering! Yippeee! Definitely give the guy/girl credit.

Are you sure that wireless tether is working in Mini CM10? I've flashed this ROM with the provided boot .img and Nope 2.6, and tether did not work. I'm pretty sure I applied that Wifi Fix as well, and nothing seemed to work for me.
Is anyone using a Jellybean ROM with tethering working? I just need to replicate as many possible working combinations of ROM and kernels,so any suggestions of combos would be awesome.
I'm posting this message via WiFi Hotspot. MiniCM10 V3, N.O.P.E. v2.6 850Mhz. No wifi fix applied apart from the WiFi keepalive app (Enabled workaround 2, reselect Always On). USB tether works too, as I use it to install Arch Linux before setting up laptop wireless drivers.
I haven't tried V4 yet. I have a Desire C non-NFC.

First of all, I am a boy! xD...
And yes USB tether works for me...but I didn't try wifi hotspot...
If you can post a screenshot on MINICM 10 forum, then it would be great, so that all people having problems with other also roms come to know...
Thanks!

Thank you for your contribution to the thread. I only have the latest MiniCM10 (V4), but I am also using Nope 2.6, just a lower frequency (700mhz, i have no need for a large OC). I've just clean flashed it back onto my Desire C, and the same results as before. Here are a few screenshots, sometimes screenshots help :
Kernel Version
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
ROM Version
WiFi Working (Worked after turning it on then rebooted phone. WiFi was on once rebooted)
Wireless Tether NOT Working
On the last picture, if I back out into the previous menu then re-select to go back into the tethering sub-menu, the "Turning on WiFi..." message disappears and the checkbox is ticked, yet there is still no hotspot being produced.
So I must be doing something wrong still?
EDIT : So I've just flashed on the same kernel and CMMini version as you've said has worked for you. I've installed the "WiFi KeepAlive" app, but I am yet to launch it, as the description of the app (which is very vague) does not seem to mend the ailment that I am having.
I'm providing screenshots of the latest and current installation on my phone. I am not sure if anything in these is out of the ordinary, but maybe someone can tell me if I've done something wrong by looking at my "About Phone" section. Once again, I've provided screenshots of the wifi tether not turning on correctly :
About Phone 1 (Kernel and Baseband Version)
About Phone 2 (CM Version, Build Date and Build Number)
WiFi Tether (Unresponsive, stuck on screen until pressing Back)
WiFi Tether (Shows after exiting and entering again, produces no hotspot visible to other devices)
Working WiFi (After switching on then rebooting, wifi becomes available, but no hotspot)
So if anyone has anything to add, I'd be grateful once more.
Thanks
So after messing around for a while, I've managed to make a slight amount of progress. I feel like I'm almost there now.
I renamed my hotspot "testet" (meant to type "tested", never changed it) and set up WiFi KeepAlive. Using Workaround 2 and Always Keep Wifi On, I managed to get my Nexus 7 to see the hotspot. That's as far as I got, as trying to connect breeds a varying set of results. Whilst it can see the hotspot, it can never fully authenticate. It will hover on "Obtaining IP Address..." and "Authenticating..." before giving me "Saved, secured with WPA2" but not actually connecting to the Internet, or it will say "Avoided poor Internet connection" (or something to that effect). It's frustrating being so close, yet so far. Here are some more screenshots to demonstrate my finds :
Nexus 7 Wifi Screenshots (Various)
The "Turning on Wifi" thing disappeared on my phone and gave me a solid checkbox ticked for once, without having to back out then back in to the menu
See the edit to my previous post to get up to speed on where I am with kernels/ROMs installed.
Thanks again.
So I guess that no one really has any clue about this? Out of the +1,000 views of this thread, only a couple of people could actually contribute?
@warrior1208 , you ported this version of CyanogenMod, and you seemed to think that wifi tether works. Maybe you could shed some light on what I might be doing wrong? I won't have answers such as "It's a known bug", you've pulled the ROM apart and put it back together again, surely you must have some idea about what's going on? I will try to help as much as I can.
@beanaroo have you seen my responses? I have replicated the same setup as you, and had no success at getting this to work. Since you have confirmed that it works, maybe you could give me some advice on what I may be doing wrong?
Failing that, recommend me a JellyBean ROM for this troublesome little phone that has wireless tethering working. I know the common response would be "look through them yourself", but obviously some ROMs claim to have working wifi tether and they do not seem to work when I try them, so if I could get a recommendation then I wouldn't have to trawl through all the "broken" ones and find one that actually works.
No offence to anyones ROMs, it's just that wifi tether is paramount in my use of a phone, and I really wouldn't like to go back to the childish looking ICS ROMs. I don't want to discard this phone either, it's a nifty little thing and I'm quite fond of it.
Thanks again,
Gordon Freeman

USB Tethering works flawlessly on MINICM10, whereas, for a working wifi hotspot(which is a CYANOGENMOD BUG), we would have to correct the wifi hotspot modules in the github source, and then produce a new build...
So, since we are not working for achieving that, we would never get wifi hotspot on aosp cm based roms...
I hope this information may clear up your doubts...
Here is a screenshot to prove that usb tether works in my ROM...
Unless someone makes a new build WiFi hotspot won't work and since most of the developers are now focusing on building cm11, it is highly unlikely that someone will create a cm10 build 4. You could try using Bluetooth hotspot as an alternative maybe?

I have been using Bluetooth tethering, but it's far from what I require. It's quite slow, and Bluetooth drains battery pretty quick. The range is also very limited. Fair enough, I keep hearing the same "it's a known bug in CM10", so what about JB ROMs that aren't made from CM10?

I'm fully aware that USB Tethering works on your build, if you had read any of my posts you'd realise that I already knew that. There was never a dispute as to whether USB Tethering was working. My problem is that @beanaroo claims that he has WiFi Tethering working with your ROM, and you seemed to acknowledge the fact that he had it working. So how can one user make something work that you (the builder of this ROM) claim doesn't work? Unless he is lying, then it must work?
So, other JB ROM alternatives to CM10 then?
EDIT : @warrior1208 I just noticed that your screenshot of your phone shows that Portable WiFi Hotspot is ticked. I know you can select it, go back in the menu and then go forwards again and it remains a solid tick, but why would you include that if you just admitted that it doesn't work? Strange.
Since the only source built jb ROM is cm10, all other ROMs are ported using cm10. That's why the bugs of cm10 are there in every ROM. If someone fixes the tethering and makes a patch or something then it would work. But so far no one has really taken it onto themselves to fix the bug..... So maybe if you could do something......

Point me in the direction of a ROM building tutorial and I'll happily try my hardest to get it working. I'm not a pro in this kind of thing, but I've been using computers for a couple of decades now so I'm sure I could give it a try. Plus it gives me a reason to get into Android development, as I love Android. I'm totally willing to put some effort into fixing this issue, even if it's just for me. If you could give me pointers on where to look, then I'll give it a shot, although if the CM guys can't do it then I really doubt I'll have a chance.
After all of this, I'm guessing that @beanaroo was lying about his ability to wifi tether on this ROM then?

I never mentioned that wifi hotspot works in my ROM...You may ask @beanaroo how he got that working...and yes I was trying in my screenshot to make hotspot stable...But it won't work in any of the Jelly Bean ROMs...So if you want it, you may revert back to a sense ROM as, the sense roms are based on stock rom and hence have everything working...Whereas, all the JB roms for our device have been ported taking cm 10 build 3 as base...I hope this clears up your doubt that YOU CANNOT USE WIFI HOTSPOT ON ANY JELLY BEAN ROM, REVERT BACK TO STOCK OR SENSE BASED ROMS FOR ACHIEVING THAT
You can Google up a 'how to build a ROM from source guide' there are plenty of good ones.

Well I've started looking into some guides now, and once I've installed Ubuntu I'll see what I can do. I think I made some progress, I managed to get the phone to broadcast a signal, there was just a problem with authenticating when connecting. I think once I manage to work out what that problem was, I could make a bit of progress.
In the mean time, I've downloaded a few Sense ROMs which I'll be flashing on to the Desire C until I buy my Nexus 5 next week, which means I'll have the Desire C available for multiple flashes and messing around without having to put my phone out of action for a long time.
Anyway, thanks for the (limited) help. I realised about halfway through that no one really cares enough to try and make it work, I thought people would be up for a crack at this. The lack of enthusiasm was probably down to people not fully reading my posts and checking out all the info I provided, but that's fine. If I get anywhere, I'll let you know.
Hey guys! I have only just joined XDA Developers so please excuse me if I have posted this thread in the wrong area. I have a Samsung Galaxy S Advance (GT-I9070) running stock Jellybean firmware (4.1.2 ITV) but as you all know the stock firmware for this device is full of bugs and freezes often. I successfully rooted my device and installed Team Canjica's CM10.2 ROM (4.3) from the thread on XDA Developers but the WiFi wasn't working. I then installed Maclaw's CM11 ROM (KitKat) because I thought that might solve the issue but it didn't. Here are the details:
Device scans for nearby wireless routers.
I type in the password for my home router.
Device saves router. "Saved, Secured" message displayed.
I tap on my home router in the list to connect.
Device says "Connecting" for a couple of seconds and then goes back to saying "Saved, Secured".
I browsed through the forums and some users suggested switching WiFi Frequency to Auto and turning off WiFi Optimisation but neither of those methods worked for me. The ROM was installed successfully and all other features are working properly so I don't think that is the issue. And my router settings are also alright since I am able to connect to it from my Nexus 7 (2013) properly. Can someone please provide me with a working solution for this issue? I will start receiving very high data usage bills soon because my data plan isn't unlimited. Thank you!
Is your ssid hidden (not broadcasted) by any chance? i had those troubles on hidden home network. Sometimes it worked after a while, sometimes it didn't. What helped me is to broadcast ssid for a moment, get connected with phone, remove broadcast (it will reboot router so phone will lose wifi for a moment). Then somehow it got connected normally

I just checked my router settings and SSID Broadcast is enabled. I tried flashing OmniRom 4.3 thinking that this may be because of a problem with CyanogenMod but the problem still persists. Is there any additional kernel that I was supposed to install perhaps?
CyanogenMod 11 version ?

Just a detail to those who have not upgraded to JB stock and think it is impossible to use it without problems:
All bugs and freezes in Stock JB currently are perfectly finished.
I use STOCK, only with modified kernel (cocore 8.2) without freezes or bugs in months of use.
Enjoy the developer's work (cocafe), because without it JB probably would be impossible in SGA. However we have JB 100% functional and bug-free.
About KK and WIFI bugs:
The only KK (or based) ROM that used without WIFI bugs was RR 20140313.
In fact, the only issue is incall vol. in my experience.
WiFi Direct, Camera -> Panorama is laggy , Screen Recorder not working Not Tested
I also noticed that the battery is worse durability.
But I went back to JB Stock -- personal preference.

Actually I did try that method. Flashed Samsung's latest stock firmware I9070XXLQL (ITV) and then rooted and installed CoCore. To be honest overall performance was much better and UI smoothness was improved. But after a couple of days of regular usage with just a few basic applications such as a note taker, train arrival time, WhatsApp etc. the device started freezing up a couple of times a day again. I admit it worked much better than before but freezes and hangs were still quite frequent. Running OmniROM 4.3 now with no issues so far except for dialer FC, laggy panorama and non functional WiFi hotspot.

This means probably you have typed wrong password. Also check that in keyboard it capitalise first letter automatically. forget the network and connect again
WIFI not working with cm-11-20140521-UNOFFICIAL-janice and cm11.0_janice.nova.201406
Same wifi problem with cm-11-20140521-UNOFFICIAL-janice and cm11.0_janice.nova.20140601. Wifi not connecting even after giving the right password (used to work correctly with jb4.1.2 and still works with desktop) only showing saving and connecting wifi. Then the wifi connection is shown to be saved. If wifi does not work with cyanogenmod11, then what's the use of upgrading?
Is wifi is not working in any custom kitkat Rom?
Please suggest a solution.
Try couple times to connect. I remember sometimes I had to reconnect 2-3 times before it gets connection. And the problem with kernel was about WIFI not turning on at all, it was not even search SSIDs.
