Connection freeze while downloading

Hi.

I have problem in following scenario:

3 routers A, B, C:

router A:

eth0--> DSL ( public IP )
eth1 --> 192.168.0.1 ( local network )

routing table A:

83.x.x.x/29 dev eth0 proto kernel scope link src 83.x.x.x
192.168.5.0/24 via 192.168.0.8 dev eth1
192.168.4.0/24 via 192.168.0.8 dev eth1
192.168.3.0/24 via 192.168.0.8 dev eth1
192.168.2.0/24 via 192.168.0.8 dev eth1
192.168.1.0/24 via 192.168.0.8 dev eth1
192.168.0.0/24 dev eth1 proto kernel scope link src 192.168.0.1
127.0.0.0/8 dev lo scope link
default via 83.x.x.x dev eth0

router B:

eth0 --> 192.168.0.8 ( direct RJ45 connection to router A )
ath0 --> 192.168.3.1 ( wireless AP -- only for bridging with router C ).
ath1 --> 192.168.1.1 ( wireless AP, for clients )
ath2 --> 192.168.2.1 ( wireless AP, for clients )

routing table B:

192.168.5.0/24 via 192.168.3.2 dev ath0
192.168.4.0/24 via 192.168.3.2 dev ath0
192.168.3.0/24 dev ath0 proto kernel scope link src 192.168.3.1
192.168.2.0/24 dev ath1 proto kernel scope link src 192.168.2.1
192.168.1.0/24 dev ath2 proto kernel scope link src 192.168.1.1
192.168.0.0/24 dev eth0 proto kernel scope link src 192.168.0.8
127.0.0.0/8 dev lo scope link
default via 192.168.0.1 dev eth0


router C:

eth0 --> 192.168.5.1 ( RJ45 connection for clients )
ath0 --> 192.168.3.2 ( wireless STATION -- bridges with router B )
ath1 --> 192.168.4.1 ( wireless AP, for clients )

routing table C:

192.168.5.0/24 dev eth0 proto kernel scope link src 192.168.5.1
192.168.4.0/24 dev ath1 proto kernel scope link src 192.168.4.1
192.168.3.0/24 dev ath0 proto kernel scope link src 192.168.3.2
192.168.0.0/24 via 192.168.3.1 dev ath0
127.0.0.0/8 dev lo scope link
default via 192.168.3.1 dev ath0


THE PROBLEM:

On first look all is fine but when I try to download
http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe
on router C, connection freezes after receiving some kilobytes (
random ). The same file is downloadble
on router A and B with no problems.
This link http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.22.6.tar.bz2
and many others
are downloadble on on all routers A, B,C with no problem.
It seems that some files freeze connection when sources by router C,
but on A and B
cause no problems.

Example of conn. freeze:

baator ~ # wget http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe
--11:25:32-- http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe
=> `putty.exe'

Any Ideas?
Thanks.
