Wifi slow on CM13 based ROMS - HELP! - Galaxy Note II Q&A, Help & Troubleshooting

Hello, I have an issue with Wifi, it's connecting just fine but it's slow, I have tried with 3 different CM13 based ROM but no luck. My Wifi is fine because the speed is good in other android phones. Is there a fix? What can I do? Thanks in advance!

Thanks for your suggestion. I'm flashing the correct way. I flashed RR too and I'm using the latest TWRP to do it. I haven't messed with the bootloader or modem. I don't wanna mess up my cellphone. I only rooted and then installed TWRP and then the ROM.

did you have everything updated like kernel, bootloader or modem?

[Q] Arc S Beanstalk WiFi problem

Hello, I am new in this forum and have a question about Beanstalk.
I have rooted my phone, installed the Kernel from the zip of the rom and then flashed the rom. Mostly all is working, but my wifi is really really slow.
And this is since I installed the rom, before the speed was a lot faster. The search didn't help me very much and google either.
So maybe someone can help me here?
I have tested Wifi fixer but it didn't change anything.
Sorry if this question is stupid, but I am not really an expert about ROMs.
Yup,
Beanstalk run whit the darkkernel 20131024, like CM10.2 LX , i test Beanstalk, LX, Carbon and i can't turn on wifi even whit the dark kernel wifi module 20131024. I think it's a kernel problem ... just wait for the next version...
I now found a solution and it seems to work, but I can't promise ^^
Flashed the TWRP Kernel (http://forum.xda-developers.com/showthread.php?t=2075549) and all is working and wifi ist now a lot faster

It's not unusual for that entry in the build.prop to be blank, and shouldn't cause issues. I think the default there should be '11 11', though having it blank should be fine (pretty certain).
> Working perfect on stock based rom
Which roms are you flashing that are giving you problems? Many of the e980 roms are bugged out in various ways, maybe it's just a quirk of the one(s) you flashed? I had a similar problem recently, wifi just would *not* stay enabled, would not behave. I don't remember which rom it was though; I flash too much.
You've flashed the Kitkat 20g modem, yes? If all else flails, you could always flash back to Kitkat stock and start over, that's guaranteed to tell you whether its a hardware or software problem (if it persists after that: hardward, got to be).

Booyah: E980 20g Kitkat TOT.
Also, with Lollipop roms, I don't think any of them are totally stable or functionally 100% yet, so that's not a place to go if you want stuff to work. There's plenty of nice Kitkat roms like PAC-rom or Carbon-Rom is you want stability and want for your phone to work fully (but thats no fun! ).

Oh, no, you misunderstood: you don't use the CWM, you only install it and then quickly install *over* it with one of Freegee's recoveries. Never use the Sphinx CWM, as you'll get errors when you go to flash roms. You only insatll the Sphinx CWM so that Freegee will recognize your device and function, it's only a stepping stone to Freegee, not a recovery you should use on its own.
And, in light of recent developments on the TWRP 2.8 front, I'd say give that a try instead. It mounts your external SD just fine. THe only things I've flashed with it are BlissPop builds and Gapps, but all without an issue yet. Go for the one with the Play theme and enjoy its gorgeous colors.
Thanks buddy.. Freegee recognized my device and installed cwm succesfully

[Q] Does the CM12.1 d2tmo work with an S3 d2lte?

I see that the nightly branch for the d2lte has not been updated for a while.
Can I use the d2tmo builds for my d2lte?
I'm guessing I will lose LTE capabilities. What about 4G?
Anything else I would lose? If it even works for my phone that is.
Thanks!
Yes, it will work, I am using it just fine on my D2lte.. for the speeds I am get H+ data.. is that close to 4G?

I think H+ is slower than 4G but faster than 3G. Not that it matters in my case though since 4G pretty much sucks in my country.
So what should I do? I have the latest TWRP and latest nightly build for the d2lte.
Just download the latest 12.1 nightly for the d2tmo and flash?

Just to be safe make sure you are on a 4.4 ROM before you do. and yea just the usual flash method.. remember to wipe it clean.

Thanks man. I upgraded successfully. Not sure I like Lollipop that much though. Seems to run smoother which is a plus. I guess I'll have to unlearn a ton of stuff. :victory:

I like the easter egg. you could play flappy bird from it Lollipop is ok for me.. it takes away lock screen short cuts tho. i barely used it anyway The thing i dont like is the Data toggle switch it takes 2 clicks vs. wifi it takes only 1.
I have to bump this thread since the d2tmo 5.1 builds are not working for me.
I was able to flash just fine but modem is not working. I cannot connect to my provider via normal cellphone nor data.
I was wondering if anyone knows if I could flash my d2lte with a d2tmo CM12.1 build and then flash it with the latest modem for my phone: TMOGalaxyS3LTE_UVUBNC1_Modem.zip
Would this work or would I brick it somehow?
Thanks!

What modem is currently on your phone? You may need to update your d2lte bootloader and modem to the latest kit kat to resolve the issue.

I reverted back to the last available CM 11 nightly for d2lte and newest modem for the LTE which is TMOGalaxyS3LTE_UVUBNC1_Modem and everything is working again.
I'm currently on TWRP 2.8.7.0.
So if I understood correctly, it would be safe for me to flash my d2lte with the cm 12.1 d2tmo builds and then flash it with the s3 lte modem?
Thanks
The latest d2tmo rom may not work unless you flash the d2tmo rom followed by a d2lte kernel.
I do recommend cross flashing the modems between the two phones.
Flashing cm12.1 builds does not change the phone's modem or bootloader.

[Solved] I'm ROM-less :(

I accidentally forgot to make a backup before flashing a new ROM and now I'm stuck with no ROM! Please help if you can. Here's my phone's info:
HTC One M9 (Telus Canadian phone) Unlocked with S-ON.
Rooted with SuperSU and TWRP v2.8.7.0.
Currently, I only have access to fastboot and TWRP. I tried flashing Revolution HD and Viper and both of them install just fine, but right after installation, my phone boots to the bootloader and will not boot to the system no mater what I do. I tried going back to full-stock but I think I need S-Off for that which I have no clue how to do with no ROM. Plus fastboot won't even show me what my CID/MID numbers are to download the right stuff for my phone if I wanna go back to stock.
I just need a ROM to work. I don't care which one. What are my options? Is there a way unbrick my phone?
Thanks in advance!

Marshmallow Firmware is what you would need to run latest rom. You could pay $25 and use sunshine to make yourself s-off and flash the latest marshmallow Firmware.

But what's a near-stock Lollipop ROM you'd recommend? Because I just installed Candy5 and Sunshine didn't like it for being too far from stock.

For the original look you get when you buy it,I'd go with leedroid rom. For AOSP I'd go with slimroms or candy.
FYI, you can install a Marshmallow rom with firmware 2.1x when AOSP only. I tried a Cyanogenmod and was working perfectly with actual nightlies.
But for Sense rom, you will have to install firmware 3.x
Thank you guys for your help! @BR7fan you're a real life saver! Just a quick update:
I managed to get S-Off and now I guess I have to wait until firmware 3.x is released for Canadian phones as I could not get it on the HTC website as of yet. @gortys I ran Cyanogenmod all day today and got annoyed with the WiFi drops. It happens so frequently and as I understand, there's no stable build for the M9 yet. So I'm taking @BR7fan's advice and going with LeeDroid for now. Thanks for pointing out that I can get Marshmallow ROM's with my old firmware.

It's true that wifi isn't as responsive as with a Sense rom. I am actually running Android Revolution HD (Lollipop 5.1) with Elementalx kernel and I'd say that Sense rom are quite always more optimized. Waiting for official OTA to firmware 3.x to flash their marshmallow version of the rom.
Patience for all!!

Looks like the old Lollipop based LeeDroid has been taken down. I have a backup of it on my phone though. I'm uploading it to Google Drive right now but it's a 2 GB file so it won't be ready till tomorrow. I hope you find something else in the meantime, but if you didn't, check your inbox tomorrow, I'll share the link with you so you can download it.

No sim with lineage based roms

Hi, i need some advice about this problem, bcz i searched that a lot but i cdnt find anu solution. Any Lineage based roms, like Viperos, Strelka, Ressurection Remix, Aokp rom etc (Any 7.x.x too i guess) doesnt work well on my n7100. Im flashing them and they are booting fine too, But when the screen came on, they says no sim, when i checked about device i dont see any info about modem. But imei is not erasing. Boot loader mj5, modem nd3 (i just changed it mj7 modem but still same) . When i flash stock rom or Hyper rom or any 4.x.x based rom works fine. I cdnt find any solution bcz i tried everything. Anyone can give me an idea about this ? bcz i stuck with 4.4.x roms. Thanks..
Is the phone running the latest by bootloader and modem? Some custom ROMs require a phone that is running the latest version of both.

Yes , found latest ones in here and flashed some time ago.
Did you update the bootloader and modem by flashing the latest stock rom or just the bootloader and modem? Not sure if this would make a difference.

I tried both way. Stock rom and 4.4.x based custom roms works fine. They were working fine with older modem and bootloader too. I tried to flash lineage based custom roms on working stock rom and custom 4.4.x too, w/o wipe. They did same thing, everything works fine just no sim silly right ?
Very strange that the sim is not detected. I don't have a note 2 to try out Lineage.
Did you post your question in the the ROM's thread in the Development Forum? Perhaps someone there could offer some more advice.

Yep its strange, i guess the real problem is those roms doesnt see what modem i have in device, bcz they are not showing that in about device. Thanks anyway, at least you tried to give some ideas
I didnt post my question in the rom's thread, let me try it.
