The usual is outdated firmware and drivers and ... firewalls. If it is all new stuff, you have a warranty issue and should not waste time fixing their broken or outdated firmware/drivers.
I've just spent the weekend trying to set up a wireless network in my girlfriend's house. This is something I thought would be relatively straightforward, but after getting everything pretty much working I have found that some websites are failing to load. Additionally, MSN Messenger refuses to work.
I noticed that all of the websites that wouldn't load were websites such as www.hotmail.com, www.msn.com, www.egg.com etc - all of which block pings. The IP addresses for these sites were being resolved correctly. I was also able to load them via an anonymous web proxy - so they were definately up at the time.
The setup is as follows -
Windows XP machines with KCorp wireless ethernet cards connecting to a KCorp 54g Wireless Router, which in turn is connected to a Zoom X3 ADSL Modem via an ethernet cable. The ISP is AOL. The XP firewall is switched off, and there is no other firewall software on the PCs. I have left the NAT & firewall config on the modem and router as the default as the default settings.
Has someone else seen these symptoms before, or does anyone have any idea about what the problem might be? Can anyone think of a reason why websites that block pings are also failing to load in IE?
Any help would be grately appreciated!
