I'm setting up a htpc system (Zotac IONITX-F based) based upon a minimal install of ubuntu 9.10, with no GUI other than xbmc. It's connected to my router (d-link dir-615) over a wifi connection configured for static IP (ath9k driver), with the following /etc/network/interfaces:
iface lo inet loopback
# The primary network interface
#iface eth0 inet dhcp
#iface wlan0 inet dhcp
iface wlan0 inet static
pre-up /sbin/wpa_supplicant -B -Dwext -iwlan0 -c/etc/wpa_supplicant.conf
post-down killall -q wpa_supplicant
Network is fine, samba share to the media direction works, until I try to upload a large file to it from my desktop system. Then it downloads a couple of percents at a really nice speed, but then it stalls and the box becomes unpingable (Destination Host Unreachable), even after canceling the transfer, requiring a restart of the network.
Same thing when I scp the file from my desktop system to the htpc, same thing when I ssh into the htpc, and scp the file from there. Occasionally (rarely) the file does pass through, but most of the time the problem repeats itself. Transfer of small text files causes no problems, and the same goes for the fanart downloads done by xbmc.
I tried the solution proposed in this
thread, and set mtu to 800 in the interfaces file, but the problem persists. Any ideas on what could cause this problem, and how to solve it?
P.S. If this is more appropriate for the network forum, I'll move it, it seems to be something in between.
