I'm having a wireless network problem with a dell inspiron 1501:
Pinging www.google.com is OK, but I just can not open the website (whether using w3m nor firefox).
Use "netstat -anp" showing that the tcp state is kept at SYN_SET, not changed afterwards.
But I try another IM application which use UDP protocol, it is OK.
So to summerize:
1. "dig www.google.com" works, the DNS resolve is OK.
2. "ping www.google.com" works.
3. opening up http://www.google.com do not respond anything.
4. Internet application using UDP protocol works.
5. Change OS to Windows Vista, I can open the website.
6. The strange problem happens after I upgrade kernel from 2.6.26 to 2.6.27.

The firmware I use is broadcom-wl-4.150.10.5.tar.bz2 at
http://mirror2.openwrt.org/sources/broa … .5.tar.bz2
I notice there are also broadcom-wl-4.150.10.5.1.tar.bz2 & broadcom-wl-4.150.10.5.2.tar.bz2.
But the file date of broadcom-wl-4.150.10.5.tar.bz2 is newer, but the files in broadcom-wl-4.150.10.5.tar.bz2
is older than in broadcom-wl-4.150.10.5.2.tar.bz2
Yet I failed fwcut the firmware broadcom-wl-4.150.10.5.2.tar.bz2 with checksum error notice.

Hi all, any hints please?
It has bothered me some days.
With wire connection, all is OK.

i'm sure that you have this problem. http://lwn.net/Articles/304724/
try latest kernel 2.6.27.4 or do sysctl -w net.ipv4.tcp_timestamps=0
Give what you have. To someone, it may be better than you dare to think.

You are right, after running
sysctl -w net.ipv4.tcp_timestamps=0
I'm now happy web surfing.
Thank you all guys!

Should we have an errata abount kernel issue and other important stuff?
That'll save a lot of trouble
