[Discontinue][no wifi n][default 518][fix hotspot] kernel based on CM7 & HCDRJacob's
The kernels based on source from CM7 & HCDR Jacob's v4.2. I built the kernels to resolve wifi drop due to my 'bad' router, which i had, is not compatible with wifi N mode of wildfire. Here is the sharing for those have facing similar issue with 'bad' router.
The following are the changes made:
Disable Wifi N mode (included in all mod changed kernels)
Boot up with default max 518MHz and min 245Mhz cpu frequency (included in all HCDR mod changed)
Apply same configuration as v4.1 to wifi driver, should be compatible with most froyo ROMs (included in HCDR mc2)
wifi hotspot fix for Sense ROM. (included in nFinity mc2/3)
update frequency table from #40. 480MHz return and 19MHz go away. (included in nFinity mc3)
Fixed FM Radio with Sense. (included in nFinity mc4)
Merged from based: add smaller footprint TinyRCU. Add missing cache routine. (included in nFinity mc4)
Out of curiosity, i compiled kernel from CM7.1.0.1 with wifi N disabled. Not tested on Sense rom(buzz-kernel-2.6.35mc1.zip)
Known issue:
FM radio will cripple the system on Sense ROM with nFinity mc# kernel.
LED sometime won't blink when receive messages.
Note: Only nFinity mod change 2+ has the wifi hotspot fixed for Sense ROM. Other kernels may has the infamous wifi hotspot issues.
HCDR mod change 1 is recommended for CM7 RC2 user. It seems much smoother.
Arco's nFinity kernel mod change 1 is for CM7 RC4+ only.
nFinity kernel mod change 2+ based on CM7 final.(Make sure is not flash from HCDR kernel.) Enjoy smartass governor with your Sense ROM
Credits to arco68's (CM7) & Jacob's (HCDR) team for the base kernel..
It is regretful that I have to stop this kernel development as my wildfire is given to my family. It was fun when I start to work on this kernel. Thank you for those who supported this kernel.
I would recommended the kernel from DK Custom if you looking for alternative kernel for Sense.
Shared my modded new kernel. So far seems working well on my phone with dk's sense rom but i yet test if it working well on cm7.
Enjoy smartass governor and overclock without breaking wifi hotspot on your sense rom.
this is perfect.
What do you mean by bad router? I'm using CM7 and lately I only get 1-2 bar on wifi signal (normally I got almost full bar). Is that how you define 'bad'?
CM7's kernel default setting should be using lower power profile for wifi to save battery power. That may be the reason that you getting less signal strength.
For my router, it is one of the first batch of Wifi-N mode product which known as draft N. This mode is not official spec, some of those routers has inferior design of Draft Wifi-N which maybe cause packet drop. For my case, i experience no wifi activity although with full bar. Hence, i reverted the driver to Wifi b/g only.

what do you mean by that?
i have cm7 stable installed and i want to install this kernel. which of these five kernels that are listed there should i choose?
and how to flash it, because you say that it mustn't be flashed with HCDR kernel installed or what? do i have to instal some other kernel(htc stock for example) before flashing or not?
thanks for the reply. you've done a great job, thats the thing i need.
If your on cm7 stable do not flash the HCDR kernel, you will break some features and there is no need the kernel in c7 is stable and smooth.

yes, but the wifi doesnt work on my belkin n-draft router!
@johensen: i tried froyo sense rom+ nFinity kernel mc2 and the wifi doesnt work
my brother has samsung galaxy tab with froyo 2.2 and wifi works normally with belkin draft-n router...
Because HDCR kernel version replace file which break interface to original driver. Hence it break compatible to other kernel unless u restore those file back.
Back to your issue, what is the symptom? It printed 'error' or can't detect or stuck at connecting?

I use DK Rom and nfinity mc3 kernel.
I have problem with fm radio.
It won't start
It started on my phone, but it seems to be some memory leak. I will look into it when I have time.
on belkin draft n router it says connecting... and then obtaining ip adress...and then disconnected.
on lynksys it connects to the router, but when i open the browser or something it just doesnt work, it says no network connection even though the wifi icon is showing connection.(the same story with linksys is on my brother's galaxy tab, but linksys works on sony vaio laptop. this linksys router also worked on my two android devices a month ago. now it isn't working on android devices, but works on sony vaio laptop, but i haven't changed nothing.)
i would be very happy if it worked on belkin draft n router, because i think it is possible to fix this, because on galaxy tab froyo 2.2. it works!
thank you for your work
@zelda89: Issue fixed in mc4 released.
@belakaca: Is the galaxy tab froyo 2.2 running on n mode? How about stock kernel? It has same problem too? I still scratching my head. Maybe you could double check your router setting.
I am using [email protected] #6 with Wildpuzzel ROM. I use standard Wifi and also ad-hoc wifi (pc-to-pc). It worked perfectly with both
On cm7 ROM I tried buzz-kernel-2.6.35 (available at cm7 nightly thread) but my mobile it failed to connect with ad-hoc Wifi. I think the issue is related to kernel and can be resolved with by flashing better kernel.
pleas suggest a better kernel for cm7 or any of nFinity kernels with strong wifi for cm7?
EDIT:
OK arco68 Just replied to mein CM7 thread about ad-hoc connection issue. it doesn't seems to relate with kernel but the ROM. Check this post for possible solution suggested by arco68
how do i overclock using this kernel?
I am using infinity mc4
EDIT: Found that I can use SetCPU to overclock.
Thanks a lot johnseen99 i just flashed HCDR.Kernel_v4.2mc1_Flashable.zip and it fixed BSSI (adhoc) wifi connectivity issue on CM7.
I was looking for solution for long time but did not flashed any kernel, I thought its problem with ROM.. Just got the idea to check if other CM7 supported kernel can resolve this problem.. and it worked.. great job!!
I cant recommend this kernel with froyo stock rom in any way. It makes my wildfire smotther but the battery almost dies in 18h prior 50h with stock kernel.
Thanks for your work anyway.
Does anyone else experience that the green notification light sometimes will stay on (instead of blinking) untill you select the new message or what so ever?
I don't know if it has to do with the smartass governor? i have kept minimum at 352mhz.
On HCDR kernel I didn't get the above...
I'm experiencing incredibly slow WIFI since upgrading a ROM and wondered if there is anything I can do about. 200k down - 20k up and pings anywhere from 600ms to 1500ms. It also fails and reconnects.
Could the problem be related to the modem that was installed with the ROM? I'm unsure is this effects wifi speed? 3G is fine and running as it normally would.
If it isn't the modem what is the nest way of diagnosing issues with WIFI? what should I try re-installing / overwriting?
It's one niggle in a very stable smooth ROM.
I'm running the following if this helps anyone;
Phone model is a GT-I9000
firmware - 2.3.4
baseband I9000XXJVQ
kernel - 2.6.35.7-I9000XXJVQ-CL281085 Ficetobeast #darkcore_2.9.2_JVQ
Build Number - DarkyROM JVQ v10.2

try a different kernel as i do believe wifi drivers are contained within the kernel
Many thanks. Is the modem part of the Kernel then? Should I try the darkyrom site to see if they have a different kernal for their ROM?

no, the modem is seperate, some people say modem effects wifi, others refute this...from personal experience i have found quite big differences with kernels, so yes, try on darkys thread for suggestions for alternative kernels
Hi guys,
So I read the threads that warn us about the bricking problem from official XXLPY. And they also told us to flash another safe kernel right away to avoid anything bad happen. But I could not find anything about which kernel is safe to use with this rom (except some said to flash GB kernel, and I assume they don't work with ICS?). So I'm wondering if anyone please guide me to a kernel that is usable with XXLPY (how to guide would be preferred ?
I do not know too much about kernels so all I'm trying to do is to stay away from bricking and get CWM to run on my ICS note.
Thank you very much in advance,
Anyone?

The new SpeedMod and Franco kernels MIGHT be safe. Time will tell.

The new franco r3 kernel might be safe as franco has disabled the emmc erase bug
Thank you guys, I just flashed franco r3 kernel. Could not tell if the problem was fixed, but now i'm left with a non-wifi galaxy note everytome i try to connect it just stays at "obtaining IP address...". And I found out that some others are aloso having the same problem as I do. Hoping for some help here cause I can't flash speedmod kernel (Idid but after reboot it's still Franco??? )
Use static IP address and it will work.

I could successfully flashed speedmod k3 using odin PC (don't know why mobile Odin did not work) and my wifi is working again, this kernel also disabled the emmc erase bug so I think I'm all good for now. Thanks anyway
CF root LPF works with me...

Im using franco kernel on LPY, fast kernel and without the eMMC superbrick bug.
does it have root?
Flashed Notecore kernel v10.6 last week and v11.1 today, VPN stopped working after that (I only use PPTP VPN). So I flashed back to v10.2 and it worked again...
Anyone else has similar issues?
I am in version 11.1. I can sometimes connect to PPTP VPN successfully but cannot access any website. I use this VPN to connect to websites blocked here in China.
In CF-Root Kernel version 5.6, I was able to connect and access any website. I changed to Notecore kernel because bluetooth won't turn on and I need it for my bluetooth headset.
I think this issue is already addressed by galvin, there on his kernel thread. He going to fix in next version.

hi why cant i overclock on this new version of kernel when i overclock my phone it say success and when i open spy cpu its running in 1600ghz
BUT How ever when i open games like hardcore games or not hardcore games it go back to 800ghz and it make my games lag?????? when i check the cpu its running in 800ghz.... i try all governo But it will go to 800 its like its defult or something??????? PLS HELp
I always upgrade in OC kernel T_T i dont know what hapend??
Hi,
I installed a custom ROM in my P990 and I got a problem which I'm pretty sure that's related to the kernel.
I'm using the new bootloader layout, CWM recovery 6.x.x and the problem is the same with any rom using the Kowalski kernels.
BTW: I am using Kowalski kernel from this post: http://forum.xda-developers.com/showthread.php?t=2097788
With the version M1, the sound recording crashes with any app that uses the sound recording modules (like the google NOW app or the sound recorder included in the ROMs). And with the Apha version the WIFI doesn't turn on at all (i've tried all releases including the last version kk-exp-127-alpha_31-newbl but without success).
I don't have other option but to go back to stock kernel. Anyone has the same problem?
For information: The roms I've tested were:
The ROM - http://forum.xda-developers.com/showthread.php?t=2420304
Avatar Rom - http://forum.xda-developers.com/showthread.php?t=2167192
Both have the same problem. Anyone?
Thank you in advance.
I think, you're using wrong Kernel. Download from Kowelski 3.1 kernel. Try with 32mb ram hack. I really don't think that 2.6 kernel works on these roms. Good luck
