Since switching to the Zyxel I can't connect to some websites using my Vista laptop wirelessly (for example google.com is always good but flickr.com always eventually times out) but disabling wireless and connecting a wire from the laptop to the Zyxel allows me to connect to all the sites. However, I also have an XP PC that is completely happy with the wireless connection and can connect to the sites that the laptop can't.
I'm totally baffled as to what might be causing the problem: Vista? The Zyxel? The combination of the two? Some stupid configuration mistake I've made on one or the other? Why does wireless work fine for XP but has selective website-loss for Vista?
Does anyone have any clues as to what it could possibly be?

When it happens again see if you can ping the Vista laptop from the other pc or connect to a share on it.
On the Vista laptop ping the router ie ping router ip
Let us know the results are you using WEP

The laptop can ping the router.
The PC can ping the laptop and connect to a share on it (and vice versa).
I'm not using WEP (I am using WPA2 TKIP).
Hopefully that info. helps someone point me in the direction of a solution.

If you are, have you tried disabling them temporarily to see if that's the problem (including the Windows firewall).
If you're running a third party firewall (Zone Alarm, Norton etc.) make sure that the Windows firewall is disabled.

There is a couple of thing that maybe wrong on the Vista pc do a ipconfig /all and post the results
Do a ping www.plus.net ; then
ping www.u-net.com
If you get a reply from them then DNS is ok if you get host not found or similar then there is a problem with your DNS settings and plusnet DNS servers manually to the wireless network.
If its not that it could be something to do with javascript/java/asp. If you can reach normal sites that only use html ie the webpage address often ends in htm or html but cant reach others then they may contain javascript.
AV and IE can both block javascript as it can be dangerous check the setting in AV and IE or try disabling AV temporary.
If you can give some examples of sites you cant reach we may have a better idea.
The final thing is Vista as the silly home and public network setting try switching it to the other one and see if that works as sometimes it get confused

Turning the AV (AVG) off makes no difference.
Switching between public and private networks (and back again) makes no difference.
Also note that Firefox and IE behave the same which means that it's nothing to do with IE settings at least.
DNS is fine - I can quite happily ping anything: including sites I can't access web pages for (such as www.flickr.com and, oddly enough, www.plus.net).
The output ipconfig /all might be significant though. Comparing the results from a wired and wireless connection I see that Teredo Tunneling Pseudo-Interface has an IPv6 Address and Link-local IPv6 Address on the wireless connection but not on the wired. However, disabling the Teredo device doesn't make any difference. Other than that (and the expected difference in local IP address) I don't see any meaningful difference between the two.
So, the wireless iponfig /all reports:

Go to Control Panel and (in classic view) > Network and Sharing Center (in standard view it's Control Panel>Network and Internet>Network and Sharing Center)
In the Network and Sharing Center click on Manage Network Connections in the menu on the left.
Right Click on the wireless connection and click Properties.
Under the Networking tab untick the box against Internet Protocol Version 6 in the box labelled " The connection uses the following items" then click on OK at the bottom. (See screenshot )
You can repeat this for the wired connection.
Are you actually using the IPV6 capability of the Toredo tunnelling?

Following those instructions to disable IPv6 didn't seem to have any effect on my problem either sadly.

Go back to the screen where you unticked IPV6 and then highlight the line for IPV4. Once that's highlighted select Properties.
On the next screen Select "Use the following DNS servers" and enter PN's servers into the boxes (Preferred 212.159.13.49 Alternate 212.159.13.50) - see screenshot - then click on OK.
It's then worth flushing the local DNS cache.
To do this you'll need to open a command prompt as administrator.
Go to Start>All Programs>Accessories and right click on Command Prompt and select "Run as Administrator" (You'll then need to OK the approval box)
At the command prompt type ipconfig /flushdns
Retry your connection.
(It's often worth trying setting DNS manually rather than use the router's DNS proxy.)

Interestingly (maybe) I've just noticed that i can quite happily complete a tracert to www.flickr.com (all the IP addresses listed resolve).And the tracert on the Vista wireless connection looks pretty much the same as the same on as on the wireless XP PC. But yet one works and one doesn't....

Try changing the MTU for the wireless adapter to 1430 - you'll need to follow the instructions on this page and see if that makes a difference.
(The symptoms you describe - being able to tracert to but not view the site - are sometimes indicative of MTU issues.)
Edit: You could also try a value of 1400 if 1430 makes no difference. Some routers have an MTU of 1400 set rather than the more normal 1500. The MTU on the PCs must be the same as or smaller than that on the router.

Cheers Paul03 (and thanks to everyone else who threw in an idea).
I don't know why I'm getting away with an MTU of 1500 on the wired connection but need a lower MTU on the wireless but that's a mystery that's not causing me a problem right now so I can look into that at my leisure.
Thanks again.
