Details

I currently have 3 kernels on my system : kernel26, kernel26ck and kernel26custom.
Since I upgraded them to 2.6.20.6, I can't seem to connect properly to some servers (including archlinux.org abs, AUR, bugs, wiki... and yahoo.com). In firefox it just displays "Connecting to..." forever.

I tried modifying some TCP settings and I tried some I found on gentoo-wiki and now it seems to work.

Here is the link to the page :
http://gentoo-wiki.com/HOWTO_TCP_Tuning#Variables_to_Change.2C_and_suggested_Values

I was using the kernel default settings and I'm behing a Sagem ADSL router. I connect through a wireless (ipw3945) connection.
This task depends upon

After booting arch 3 times with different kernels I tried connecting -> didn't work.
Then did the TCP config with sysctl -> worked.
Then I rebooted twice with the default config and it works without problems.

I have no clue of what happened, but it seems fixed now.
Sorry for opening this.
