[Q] Bad WiFi Spped with KTmanta Kernel? - Nexus 10 Q&A, Help & Troubleshooting

Hello Together,
i found a very strange thing in the KTmanta Kernel (im using the new from 04/19/2013)
With the Stock Kernel in the Stock Rom 4.2.2 i have a much better Wifi Speed (in Speedmeter my 50MBit+)
now with the KTmanat Kernel i have around 25 - 30MBit...
Is this right? Now i cant anymore stream Fullhd with DTS to my nexus 10
With The Stock Kernel this is possible and works like a sharm.
Can someone help me?
greeting

It is highly unlikely that there is much of a change in the new kernel, add these lines to your sysctl.conf and see if there is a change.
Code:
net.core.rmem_max=524288
net.core.wmem_max=524288
net.ipv4.tcp_rmem='6144 87380 524288'
net.ipv4.tcp_wmem='6144 87380 524288'
net.ipv4.tcp_timestamps=0
net.ipv4.tcp_sack=1
net.ipv4.tcp_congestion_control=cubic
net.ipv4.tcp_window_scaling=1
net.ipv4.tcp_tw_recycle=1
net.ipv4.tcp_tw_reuse=1
You can also search for other net tweaks to add to build.prop or init.d script, just make sure any specific signal tweaks only have wifi or default in the lines, 3g/4g/umts/cdma are only for carriers. If you still can't resolve the issue you can always try another kernel like Trinity or stick with the default

KTManta kernel uses the latest wifi drivers and patches, so it is possible that one of these patches is not playing well with your router or the traffic in general.

[Q]Paranoid Android hybrid settings will not save

Hi Everyone,
Sorry if this question has been asked before but I have been having a bit of trouble when I attempt to change any sort of hybrid setting using PA. For example I want to change the UI to Tablet UI. When I hit "apply" the screen acts as if it's resizing but it stays exactly the same size and does nothing. This also happens when I try to change the DPI or settings of any app. I'm running built number JSS15J PA version 3.94. Franco Kernel 3.1.10 nightly.
Thanks in advance for any help.
same problem
I have the same problem on my galaxy nexus gsm. My hybrid settings are the same as before updating but I can not make new changes or revert the changes that I did before updating to 3.94. can someone please help with this problem?
btw did you by any chance perform a dirty flash, because that's what I did and I'm thinking whether it caused the problem or not.

LG L5 Wifi cannot find my network after installing OC Kernel

So, I've installed CM 11 Beta 3 + an OC Kernel and now it just won't find my network, it just keeps searching and searching and finds nothing, I've also tried writing it manually but it says "Out of range", it is needless to say that before installing the kernel the wi-fi worked pretty well, it's not a ROM trouble but a kernel one I guess. I've also tried other kernels and it keeps failing, also tried different ROMs such as Pure AOSP 4.4.2, CodefireXperiment and it doesn't work either, any idea? somebody?
The wifi kernel fix isn't working either.
works great for me

Many thanks to our Lord for his hard work in last weeks.
Now it is a "real" S5 ))
Sound control?
The Boeffla control app v. 2.1.73 only offers volume adjustments in the Boeffla-Sound section. I tried running the Boeffla Sound Control App v. 1.7.1 from the market as well as a presumably modified version I found on XDA, but both force close immediately. Is there a way to take more advantage of the Boeffla-Sound options on this kernel (2.0-beta3-CM 12.1)?
Issue with CPU and GPU frequencies
Hello...
I have a Samsung Galaxy S5 and i have installed CM12 with the latest kernel 1.0 beta3 and i experience freezes and hot reboots...
I have not overclocked anything as you can see from the pictures and i have left all frequency clock settings at default values, but when i go to CPU-Z i see the values of CPU and GPU overclocked...
In the attached images i have the default settings in Boeffla for CPU on 2457MHz and in GPU at 578MHz and in CPU-Z i see that max CPU frequency is 2.84GHz and GPU is 657MHz...
Why is this happening?
Thank you in advance for your help...

Issue with CPU and GPU frequencies
It is being answered by Lord Boeffla...
All is normal. Tools like cpu-z and others always display the maximum possible frequency, regardless of what you cap the frequency to.
So, it just shows something not correct.
You can verify that very easily by using tools like CPU Spy etc and you will see, these high frequencies are indeed not used unless you allow it.
The reasons is: These tools always assume, when overclocking frequencies are available, they are used. Which is not the case by default in my kernel.
nameless rom KLTE 4.4.4
does it work on namelessrom nightly with stock kernel?

Hello Boeffla,

I'm very happy with the kernel and i never had problems with the kernel at all (using smoove, interacitve, conservative)!
I really appreciate when you further support the S5 development!

I tried this kernel (2.1-beta8) on BlissPop v3.6 (BlissPop-v3.6-klte-OFFICIAL-20150701-2254), but some features didn't work (ex: couldn't use tethering).
IMPORTANT: BlissPop is "customized" rom, so you must read and understand when want to use:

Kernel working with s5 SM-900m?
I would like to test this kernel with Exodus ROM 5.1.1 (http://forum.xda-developers.com/galaxy-s5/orig-development/rom-team-exodus-klte-t3135876). Is it compatible? If yes, how do I know what version of the kernel to take (CM11, CM12, CM12.1, Stock Lollipop 5.0)?
Thanks.
Problems with bluetooth on g900t
I have a g900t with cyanogenmod 12.1 installed. Whenever I try to pair my sony speakers to my phone the speakers do not work properly. So my question is, can I installed this kernel on my g900t? would this fix the bluetooth problem?
Thanks in advance.
Hi, I am new to this. Just got my S5 today.
The phone still got Android 5.0 with TouchWiz on it (original Samsung firmware) and is not rooted yet. I want to install CM 12.1 later. What kind of kernel do I need now? If I install the kernel via Odin is my phone then rooted and ready to install CM 12.1?
Thanks for any help.

I installed Boeffla Kernel and CM12.1 successfully. All works fine. However, my phone always says that I have no root rights. Boeffla Kernel for sure is installed and is showing up in my settings. What can be wrong?

You have to enable root, or to flash SuperSU (a third party, actually the most popular root solution for Android.).
I would actually like to recommend you the stock CyanogenMod root, but I myself am using SuperSU for a while, and I would have to search how to use the stock CM root with 12.1.
So either install SuperSU app from the play store, and download this zip: download.chainfire.eu/supersu, boot to recovery and flash it, to enable Chainfire's closed source root, or Google 'How to enable root on CyanogenMod 12.1' to find out how to use CyanogenMod's own root solution.
Edit:
So I dont have to type everything (instructions how to enable CyanogenMod's own root implementation, IIRC, and if nothing has changed in the meantime, it is Koush's implementation, which is open source:

Need help finding the cause of the static on boot problem

OK, i know that most roms have the static on boot problem, which in itself isnt a big deal. But, i have found that the werewolf kernel doesnt have that issue. could someone help me find out why that kernel doesnt have that problem so we may fix other kernels? the kernel ends up freezing my UI and i have to reboot. Not sure if its related or not. I havent seen this anywhere so i thought i would post it. i am willing to test the kernel if i can get some help. Or just point me in the right direction on what i would need to look for if i tried to edit the kernel myself
It's open source isn't it? Look at the difference between the unmodified kernel source. I use that kernel as well to fix comfort view while not having static. The first time I tried the kernel my screen didn't respond to touch at all, not sure why it works now
lg kernels have the issue. werewolf is build from qualcomm sources with drivers added for our phones(same way lineage does it which is why theirs is fixed also) The fixes for those kernels cannot be applied to a standard kernel.
