Unable to access all websites using DSL router


Ok here goes, My set up is as follows:

My Internet service comes from a cable provider, The cable Modem is a TERAYON model TA102. IP adress and DNS are provied by DHCP. This Modem is then connected to a DLINK DL-604 Broadand Router. The Router WAN is set to DHCP and the LAN IP for the Router is I am using this set up to share the internet connection. My PC IP is set to and the gateway is set to the Router at


i have internet access ok but when I go to certain sites eg: www.ebay.co.uk i cannot access the page. When I plug the PC direct to the Cable modem There is no problem.

PLease Help  this is driving me MAD.  I have gone through the Router setings and cannot find any reason for this, I have no filters set and  the internal firewall is off

telnet www.ebay.co.uk 80

One more thing:

Try to connect directly to ip address of  www.ebay.co.uk

write instead of  www.ebay.co.uk in your browser.
this isn't the first time that someone has had some unsual problem with a DI-604 read this: http://www.experts-exchange.com/Networking/Q_21008579.html

It sounds like the router use a different DNS server than provided by your ISP so I think the solution may be: "Goto the status tab in the router and note your DNS servers provided by your ISP.  Enter those in the primary and secondary DNS servers on the Home-> WAN page in the router."
this refers to ICS, but also applies here
change MTU on client
use drtcp to change the MTU settings
drtcp (free)

This is almost certainly a MTU problem, to check for sure run the test here http://www.dslreports.com/tweaks then download DrTCP from the same site to adjust your MTU as recommended.
its certainly a DNS issue with your Modem and broadband router can u check what dns are using at the PC u browse the site and can u ping ebay.co.uk or any site u r not able to access.

Reconfigure the DNS on the cable modem and the router and your PC it should work

Thanks for your help so far guys.  still doesn't work though.  I have done the MTU check and 1454 is my optimal setting which I have now set in all devices. Also I have tried setting the router to use various DNS servers including the ones used by the ISP.- still no luck.   It gets even stranger now as I have tried a Netgear RP614 router
 and the same problem exsits with that router aswell????? One thing I have not mentioned is the ISP set up.  I live on  a large Urbanisation in spain and the central node where the cable is distrbuted from gets its internet connection via a sattelite link. It has a huge bandwidth as there are about 300 clients with a 1MBIT  connection with virtually no latency.

Ok I can load ebay with the IP address Must be something to do with DNS
cjenn1161Author Commented:
What is special about the hughes DNS servers? would I benefit from using them here in Spain?
Rok BrnotCommented:

Just for test - can you try and change DNS (on your router) to this :

Primary DNS     :
Secondary DNS :

then run ipconfig /all on your computer - if DNS servers doesnt show in response -
check again TCP/IP settings if you have <Obtain server addresses automatically> selected

I hope any of this helps...
from a prompt thype
ping www.ebay.com
see if it resolves the correct ip (It won't get a response, they are blocking ping requests)
Pinging pages.ebay.com []
if it doesn't resovle the ip then it usually is a nds error, if it resolves the wrong ip, check y ou drive for a file named "hosts" not hosts.sam, just hosts (no extension)
open in notepad and remove all entries execpt localhost
then if using w2k/XP
from the prompt type
ipconfig /flushdns
then try again
the hosts file (if using w2k/xp shuld be in %systemroot%\system32\drivers\etc

Hi did as you sadi, the ip waas wrong, correct now,  problem still persists.  rbrnot's dns servers did not work either. Incidently when using another PC as a gateway all is fine
Rok BrnotCommented:
Does ipconfig /all show correct DNS servers ?
cjenn1161Author Commented:
Yes Ipconfig shows DNS correctly    ie:  (the router itself)  I have tried setting dns servers other than the router and problem still the same
With dns at
ping   pages.ebay.com  getting      []
ping  www.ebay.co.uk and getting []

from www.dnsreport.com:

www.ebay.co.uk A record is
www.ebay.co.uk.  A [TTL=300] [US]
www.ebay.co.uk.  A [TTL=300] [US]
