I'm currently experiencing a bizarre network problem.
I used to have the following setup:
adsl modem/router connected to a switch
on this switch 1 or 2 PC's were connected @ 100 Mbps
a second router (with WLAN) was also connected to this switch.
on this second router the laptop was connected wireless and 2 PC's @ 10 Mbps (reason for being 10 Mbps is the fact the UTP cables were so long and interfering with other electrical equipment 100 Mbps wasn't possible). And it worked perfectly.
Sadly, 2 weeks ago the router with WLAN died. And Friday evening the adsl modem/router died as well. So time for some new equipment. I bought a DLink DSL-G604T adsl modem/router with WLAN.
Now all PC's are connected to this router (100 Mbps and 10 Mbps). I've disabled the WLAN for the moment, cause I first want the regular LAN to be set up properly.
DHCP client is set as follows:
IP/Gateway: 192.168.1.1
Primary DNS: 192.168.1.1
IP start: 192.168.1.100
IP end: 192.168.1.254
Lease time: +/- 12h
The connection for the PC @ 100 Mbps works like a charm, but there are some issues with the PC's connected @ 10 Mbps: they won't connect to all websites.
For instance following sites won't open on those 2 PC's:
www.swisscarsightings.com
www.yahoo.com
www.hotmail.com
www.audi.de
www.f1pits.net
Though when I ping these sites on these 2 PC's I do get a response. I've tried to fiddle with the MTU value of my adsl connection, but no improvements. I also tried to connect the 10 Mpbs PC's indirectly to the router via a second switch, but the problem remains.
Does anyone has an idea why this happens?
