Home network is fine, until i try to rsync/scp


Hello,

I have a home network set up using a Belkin F5D6230-3 wireless/"physical" router. I have 3 computers:
one wired Windows XP (which we can ignore),
an ooold laptop Compaq Presario 1200 running Xubuntu 5.10 (Ubuntu+Xfce) connected through a Belkin F5D6050 wireless network adapter, and
my PC running Slackware 10.2, wired to the router.

I want to transfer some MP3's from the PC to the laptop. First I tried scp and it worked perfectly, with ~600kbps rates, until suddenly, after the say 15th file, it slowed down until it said "stalled". Then I kept trying but nothing. I tried secpanel but it didnt help either. Then I read about rsync, so I issued
rsync -avz --ignore-existing 192.168.2.8:My\ Music/LoungeChillOutJazz/ .
(192.168.2.8 is my PC, *.31 is the laptop).
That worked fine. Then the same thing happened as with scp, it just stopped working after it transferred some songs. Except that now my router kicks my PC out. I can't even ping the router. When I got the connection back (by waiting some 5 minutes and issuing sudo /etc/rc.d/rc.inet1 stop; sudo /etc/rc.d/rc.inet1 start at the terminal), I tried rsync'ing the other way around (from the PC to the laptop: rsync -avz --ignore-existing My\ Music/LoungeChillOutJazz/ 192.168.2.31:.) and now it doesn't even get through ONE file, and still kicks me out. The old laptop keeps its connection to the router intact through all of this. I am able to download files to my PC from, for example, BitTorrent.. It's this intranet that's not working right.
I read that it could be some bad mtu settings so i set them on both computers to 576 as suggested (ifconfig [wlan0/eth0] mtu 576), but not much happened.

I don't know what is going on, but it's really annoying.. Can anyone help me with this?

it sounds like something is interfereing with your hard disk access possibley..or some other bottleneck like swap or buffer over loads.

what does ps -A | more say when this all goes on?

or maybe that ooold laptop is just ready to croke? lol

good luck.

Well, about the mtu settings, they default on both computers is 1500, but the page I read (can't find it again) suggested to change it to 576 on both computers. That didn't work. Anyway, I finished transferring all the MP3's I wanted (I tried again and it worked!). I couldn't post the ps -A from the laptop because the terminal I ran it in crashed. I will be going away from home for a couple of weeks, so I won't be able to answer anymore. Thanks for trying to help though!
