When I run into this type of problem its normally due to an MTU (Maximum
Transfer Unit) size problem on a network device somewhere.
In your case there are just two devices the DG834 and the affected PC so
I'd suspect that the affected PC has its MTU set too low.
Use the ifconfig command to list the current MTU
laptop at duncow:~/$ ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:21:9b:6e:bf:6f
inet addr:192.168.1.106 Bcast:192.168.1.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:717893 errors:0 dropped:0 overruns:0 frame:0
TX packets:640735 errors:0 dropped:0 overruns:0 carrier:0
RX bytes:126384910 (126.3 MB) TX bytes:47282904 (47.2 MB)
The normal value for ethernet is 1500 so if it is lower than that try
setting the MTU to 1500.
sudo ifconfig eth0 mtu 1500
If that fixes it then you need to determine why the MTU is set lower.
The normal reason for changing MTU is to fixup problematic broadband
providers routes but that should really be done in the DG834 itself not
on the LAN. I know that DG834 does have a setting for that.
