I'll assume you're using XP Home.

1. Control Panel -> Internet Options -> Connections -> LAN Settings
Uncheck everything.

2. Check your zd8000 wireless settings. If you have typed in your
DNS servers, the primary DNS server IP is probably wrong.

3. Go into they BT Home Hub, of which I know little, and make sure
the WAN settings are all DHCP. If you have specified DNS servers, the
primary is probably typed wrong.

4. Check the HP web pile for updates to your wireless drivers. Same
with the BT Home Hub.

5. You don't indicate how the speed looks after you successfully
connect to a typical web server. Just because it can lookup an
address doesn't mean there isn't something else wrong. If you have a
weak signal, or lots of interference, you're going to have additional
problems. I suggest you run a speed test with one of the multitude of
online services, preferably as close to BT.NET as possible. I'm not
familiar with UK servers. If you have a strong signal, and the
results are just fine via a wired connection, but dismal via wireless,
you may have an interference problem.

Such interference will cause packet loss, which also might be
responsible for the delayed DNS lookups.

6. Try this experiment: Find out the IP addresses of the DNS servers
used by your ISP. There should be two of them. Might as well do that
for you:

| C:\>nslookup
| Default Server: DD-WRT
| Address: 192.168.1.1
| > set type=NS
| > btcentralplus.com
| Server: DD-WRT
| Address: 192.168.1.1
| Non-authoritative answer:
| btcentralplus.com nameserver = ns2.bt.net
| btcentralplus.com nameserver = ns0.bt.net
| btcentralplus.com nameserver = ns1.bt.net
| ns1.bt.net internet address = 217.32.105.91
| ns2.bt.net internet address = 217.32.105.90
| ns0.bt.net internet address = 217.35.209.188
| >exit

Ok, there are your name servers. Now go to:
Control Panel -> Networks -> Wireless_card ->
Properties -> TCP/IP
and type in the first two DNS servers. Save.
Run:
ipconfig /flushdns
which flushes the local DNS cache so that doesn't mess up the test.
Try it now. If that speeds up DNS lookups, then there's something
wrong with your BT Home Hub or it's setup. What you're doing is
bypassing the DNS cache in the Home Hub.
