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:
  1. Disable Wifi N mode (included in all mod changed kernels)
  2. Boot up with default max 518MHz and min 245Mhz cpu frequency (included in all HCDR mod changed)
  3. Apply same configuration as v4.1 to wifi driver, should be compatible with most froyo ROMs (included in HCDR mc2)
  4. wifi hotspot fix for Sense ROM. (included in nFinity mc2/3)
  5. update frequency table from #40. 480MHz return and 19MHz go away. (included in nFinity mc3)
  6. Fixed FM Radio with Sense. (included in nFinity mc4)
  7. Merged from based: add smaller footprint TinyRCU. Add missing cache routine. (included in nFinity mc4)
  8. Out of curiosity, i compiled kernel from CM7.1.0.1 with wifi N disabled. Not tested on Sense rom(

Known issue:
  1. FM radio will cripple the system on Sense ROM with nFinity mc# kernel.
  2. 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.

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.

nFinity kernel mod change 2 based on CM7 final.(Make sure is not flash from HCDR kernel.

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.

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?
