Finally, my connection is super stable now. I think I was able to nail down
the culprit. The issues I am talking about here is when the wi interface
gets flooded like when we are doing an ftp to the same host that has the wi
interface card. I noticed that when I downloaded a 4mb mp3 files. I lost my
connection in Windows XP running WSFTP_LE in just 2% :(
Here is the chronological order. Btw, same test using wsftp and same files.
1. Previously, Primary 1.0.7 S 1.3.6, there were seek timeout issues
2. I upgraded it to 1.5.6 and the S that came with it, much more errors such
as Busy won't clear bit. This is annoying since you can't do anything in
your console. You will be only able to gain control once you start seeing
unable to fill buffer on NIC 1546 bytes. Something like this.
3. Downgraded to 1.4.9 and was hoping that it will be stable. Same behavior
as in number 2.
These testings are done with the patch I found which was DELAY(1). This
didn't help too.
I actually almost gave up.
Anyways, I also read somewhere about WEP issues. I modified my wifi.sh
script to disable wep (wicontrol -e 0). I also modified my Windows XP's
config wherein WEP was unchecked. So I got connectivity. Executed 12 windows
of cmd.exe running simple ping. While ping where running, I also tested
wsftp client. I REALLY CAN'T BELIEVE IT. It's working properly and it's not
dropping my connection. Now, you will ask me, what about your security?! I
did create a IPSec Policy using MMC in Windows XP, then I also created
spdadd IPSec policy in FreeBSD plus, I installed racoon so that it can
automatically exchange keys. I'm very happy now!!!
I can say that there is a buffer code issue in WEP module. I wish I know how
to low level code. But, anyways, this is my 2 cents.
Have a great day guys.
