web browsing limited, why?

To start off:
I installed Suse on two seperate ocassions and both times had the same behavior as I now have with Mandrake Linux 10.0 installed on the same machine along with 3 flavors of Window$.

Problem:
I can browse to some sites such as Yahoo but am unable to view search results or connect to any Mandrake update site. Get an error:

An error occured while loading http://www.mandrakesoft.com/:
Could not connect to host www.mandrakesoft.com

This same problem was exhibited in both installations of Suse 9.0 and 9.1. I did post the question in the Suse forum and recieved one suggestion: Check browser settings.

I then did numerous browser setting changes and reboots, problem reamained. I am stumped as to what is happening.

Current System:
Mandrake 10.0 clean install no modifications
Compaq Prosigna Desktop PII 450Mghz
256 Mb Ram
TNT Riva 128
Ethernet D-Link DFE-530tx+
WD 20 Gig hd
Blitzz BWA 711 Wireless Router
Internet connecion = cable

This is what I get attempting to access mandrakesoft.com

Code:

---

The page www.mandrakesoft.com/: you are looking for is missing. The webmaster of this website has been warned.

Seems this is an issue with their server not your end.
The yahoo issue :what is the error?

I can open yahoo's home page but when I perform a search I get the same error and no results are posted. Tryed to open Google but same error. So far Yahoo is the only web page that could be opened

Which browser?

Konqueror

right now I'm installing Suse on a different computer to see if I get same results. Suspicious it could be hardware on old desktop or router.

Try going to a few sites using the ip address instead of the url.

After installing Suse 9.2 onto a different machine the same problem appears. I tried to use the Suse IP address 195.135.220.2 and Konqueror gave error:

An error occurred while loading http://195.135.220.2
Timeout on server
Connection was to 195.135.220.2 at prot 80

Please keep in mind I have a wireless router/firewall, and now I feel this may be the problem.

Current specs:
Suse 9.2
AMD Athlon 2100+ XP
Asus A7N8X onboard LAN & Sound
NVidia RIVA TNT2 Model 64
512Mb DDR Ram
40Gig WesternDigital
Cable internet connection through a Blitz BWA711 Wireless Router/Firewall

Ok thanks for the help, I figured out the problem. After I disconnected the router/firewall and connected the linux machine directly to my cable modem and did a fresh install I can now do online update and the such. Now I will turn my attention to using my router/firewall with linux to access the internet. :lol:
