Scenario:
- I have a HAG (Home Access Gateway, which embodies an ADSL modem) 
installed by my provider;
- the HAG has three RJ45 ports; when a PC is connected to one of 
theese ports, it gets an IP address via DHCP;
- I have connected a Belkin wireless rooter to one of theese ports;
- I connect my PC to another port, and/or to the wireless router (by 
running modprobe ndiswrapper; then /etc/init.d/net.wlan0 is ran by 
ifplugs - at least, this is what I can guess ;-).

When I run Windows, my wireless connection is "normal", but when I run 
Gentoo there are strange delays. For example, a simple ping is fast 
under Windows, very slow under Gentoo. I have to stop net.wlan0 to 
get "normal" pings again.

As far as I can understand, it is a matter of metric.
When I only connect my PC to the wireless router, I can see:

a) under Windows (the output is in Italian, but I'm sure you can read 
it - using a fixed font may help ;-):

b) under Gentoo:

b.1) fast:

0.0.0.0     192.168.2.1 0.0.0.0       UG    2000   0     0 wlan0

b.1) very slow:

sergio ~ # route
Kernel IP routing table
Destination Gateway     Genmask       Flags Metric Ref Use Iface
192.168.2.0 *           255.255.255.0 U     2000   0     0 wlan0
loopback    *           255.0.0.0     U     0      0     0 lo
default     192.168.2.1 0.0.0.0       UG    2000   0     0 wlan0

I can just notice an astonishing difference between metrics: 25 under 
Windows, 2000 (!) under Linux.

I've tried "route del default" and then "route add default gw 
192.168.2.1 metric 0", but the wireless connection was still slow.
"Slow" means, for example, that if I use my browser and go 
to "www.google.com", "Looking for www.google.com" lasts too mach.

Any hints?
Thanks
Sergio

The absolute value of an interface metric is meaningless, they only
matter in relation to other interface metrics active at the time.
They are used to decide between interfaces when a host can be reached
through more than one interface.  So for example, if you have a dialup
connection as well as broadband, you would want the broadband
connection to have a lower metric than the dialup so that it is the
'preferred' interface.

What do "ifconfig wlan" and "iwconfig wlan" report for the fast and
slow states?  And the host that you are pinging, is a remote internet
host or something local (like 192.168.2.1)?

Thanks for your answer.
My pings (perhaps all DNS lookups) are slow even if connect my PC to 
both the wireless router and the cable, i.e. when there are both 
a "fast" (metric 0) and a "slow" (metric 2000) interface.

> slow states?

Fast (i.e. normal ;-) state happens only when net.wlan0 is stopped.
When I start net.wlan0:

sergio ~ # ifconfig wlan0

Remote internet hosts (f.i., google) and local.
BTW, I can't ping 192.168.2.1, i.e. the wireless router. But I can 
under Windows!

Xorg 7.1 + ati-drivers 8.29.6 
I just install ati-drivers using guide in gentoo-wiki. 
Result is: "Screen(s) found, but none have a usable configuration"
So please help :))

Apparently ati-drivers-8.29.6 does not support the Radeon 9200.  You
should probably use the opensource 'radeon' driver instead.  Replace
fglrx with radeon in VIDEO_CARDS in /etc/make.conf, and "emerge
--oneshot xorg-server".  That should bring in xf86-video-ati, and you
can then replace the fglrx driver in xorg.conf with radeon.

FYI, the radeon driver offers full 3D support for the 9200 if you
enable the right kernel drivers also.

Are both wired and wireless enabled?  Your original posting doesn't
show any records for eth0.  In the 'slow' state, what is the output of
'ifconfig -a' and route?

However....

NB: route and ping www.google.com are fast.

After modprobe ndiswrapper and /etc/init.d/net.wlan0 start:

route is slow, route -n is fast.

I didn't follow this thread completeley but having two default routes
is definitly the cause of slow (or even unworkable) networking.

I would write a script that is run at bootlevel to determine if
you have eth0 or wlan0 or both and change things at the default
level accordingly (including dhcp, iptables, routing and maybe
other things as well).
I did this on several machines and laptops. If the existence of
wlan0 depends on a pcmcia card you can simply test it at bootlevel
with ifconfig. If wlan0 is always existing (e.g. by a pci-nic) but
you don't want to use it, you might create different ways of
booting the system (with or without wlan0) by suffixing your
kernelcommand in grub.conf with wlan0 or not and in your script
test with "grep wlan0 /proc/commandline" (or something like that).

Regards,
Hans.

Ok, two things to try.  First, remove the 192.168.2.1 nameserver from
resolve.conf.  That "nameserver" may be broken and unable to resolve
names on the internet.  This should help the "ping www.google.com"
case.

Second, does "ping -I wlan0 192.168.2.1" work better?

Oh, one last thing....you don't have any firewall rules enabled,
right?  (iptables --list)

Yes, I've already said that, but.... you are great! ;-)
I read your message this morning quickly, when I was going to work, 
and didn'understand it.
Then I've spoken to a colleague of mine, a true network guru, a very 
capable ethical hacker, and I've understood! (I suppose....)
My wireless router:
a) runs a (WAN) DHCP client to get its IP address and the IP addresses 
of my provider's nameservers;
b) it get those IP addresses to send them to me when I run a DHCP 
client; my wireless router runs a (LAN) DHCP server too, but it is 
*not* a nameserver;
c) my DHCP client was configured as usual, i.e. "replace 
my /etc/resolv.conf"; I've added

dhcpcd_toynet="-R -h sergio"
               ^^

to /etc/conf.d/wireless and restarted /etc/init.d/net.wlan0.
Now... there is no line "nameserver 192.168.2.1" in 
my /etc/resolv.conf and ping www.google.com is fast ;-)

BTW: This evening I've started running Windows at first. ipconfig /all 
showed three nameservers, and 192.168.2.1 was the first one.
However, when I ran nslookup, the message was clear: 192.168.2.1 is 
not a nameserver. Why the difference between fast (Windows) and slow 
(my previous Gentoo box) Internet pings? Perhaps because the Windows 
timeout is short: 2 seconds. I do not know how to eventually set such 
a timeout in Linux....

> Second, does "ping -I wlan0 192.168.2.1" work better?

Nope. ping <-I wlan0 or -n> 192.168.2.1 is still blocked.
Well, it's just a nuisance, but I'll keep looking for a solution.
Any hints would be greately appreciated ;-)
That's not strange, because:

Right. I wish to configure my real (wire and wireless connection to my 
ISP) and virtual (VMWare) networks, and then enable iptables.

Thanks a lot, as usual ;-)
Sergio

PS: I wish to thank Thomas Sjolshagen (private message) and Hans de 
Hartog too. If one doesn't feel lonely when he tries to solve a 
problem, well.... that helps a lot! My English is poor, but I hope 
that you understand what I mean ;-)

Yes, it was OT and very few of you are interested ;-)
However, somebody would like to know who the killer was.

The original subject was "wlan0 is sssloooow [99% SOLVED]" because  
pinging the Belkin F5D7230-4 wireless router worked from Windows but 
not from Linux.
The answer is: because Windows sends ICMP messages with 32 bytes of 
data, Linux sends them with 56 bytes of data.
Moreover, Linux IP datagrams have the DF (don't fragment) bit set, 
Windows ones have not.
On Linux, ping -s 15 192.168.2.2 works.

Cheers
Sergio

How did you ever find this out?!  I'll know that's another thing to test when 
an access point is playing up.  I wonder why belkin is set up this way.

Thanks for sharing.  :-)

I'm very glad you did post this update as here in the office we had this 
very problem three weeks ago. One morning every non-Windows host in our 
building suddenly could not see past the gateway, could not ping it and 
was essentially off-air. We eventually tracked it down to one of these 
Belkin wireless routers, but never figured out why it was doing what it 
did. 

Now we do know, so thanks for the heads-up!

I used two "tools": Douglas Comer, "Internetworking with TCP/IP", and 
Wireshark (former ethereal).
I'm still installing my new laptop, f.i., I've not yet setup a 
firewall. My former firewall was based on the "Iptables Tutorial" by 
Oskar Andreasson, but I didn't understand all the details. So I've 
started studying, i.e. reading Comer and looking at frames, 
datagrams, etc. by Wireshark.
I needed that. For example, I had used nmap to look for an echo port 
on the Belkin router, but ping, i.e. ICMP, doesn't know anything 
about ports!
As to the ping problem, I started a Windows virtual machine by VMware 
Player, then Wireshark both in the Linux "real" machine and in the 
virtual one, then pinged the Belkin router. Looking at the output 
produced by the Linux Wireshark and by the virtual Windows one, there 
were just two differences: the DF bit, and the data field length in 
the ICMP messages.

I think that a router should send ICMP messages such as "fragmentation 
needed and DF set" (Type 3, , Code 4) and "time to live exceeded in 
transit" (Type 11, , Code 0), but Belkin does not (traceroute, and 
tracert, 192.168.2.1 print stars).
The Belkin 54G wireless router, F5D7130, had serious security holes:

My model, F5D7230, is more secure. Eventually too much ;-)

I must thank all of you. Gentoo would not be such an attractive system 
without the continuous support by all of you.
