I have a broadly similar problem and wonder if posting to this thread might help others.

Two laptops. Both on WiFi connections to the same router.
One laptop (an Acer) works without problems in all elements described below.
Problem laptop (a Dell Mini 9) upon reboot has 5-10 mins before internet access is not available - by which I mean to http pages in IE7. Even if I do not use IE to access the internet after 5-10 mins this is not possible. Message received is the standard 'page cannot be displayed). WiFi signal is strong, and IE access to all sites fine from the working laptop (upon which I am typing this)
Problem laptop *can* access https pages
Problem laptop can ping all websites (http and https)
Problem laptop - have tried netsh commands listed below. Also general check on registry/malware/zonealarm etc. None present (or at least obvious).
Problem laptop has AVG 8.0 free plus Windows Firewall. The latter two can be disabled but make no difference to access
Problem laptop can be rebooted and access is fine, but only for 5-10 mins.

Any thoughts?

Works best for you to have your own thread, which is why I have started this one for you.

Are you sure you have no non-Windows firewall or security suite? Or maybe used to have one that left some remnants behind?

What operating system?

Make sure you have the latest correct networking driver. If you already have the latest use Device Manager to uninstall it; reboot and let Windows discover the adapter and reinstall the driver.

Thanks for your prompt response. A new thread makes sense.

I'd disabled all the firewall rules on the Netgear router, and the windows firewall on the problem laptop, which made no difference. Puzzling thing is that the router serves two laptops, and the other is fine, which indicates that the fault is on the problem laptop. It is XP Home sp3 (laptop originally came with sp1 I believe and was hotfixed up to sp3 via assorted MS updates).

Only AVG 8.0 free anti-virus, which doesn't include any firewall or additional security layers which could cause this to my knowledge. Will disable it and retest.

Will also check the network driver later.

By the way, similar posts indicate the internet comes back up after a spell, then back down again. On my problem laptop once it goes down, it stays down (but I can still ping, and can still access https sites).

The router firewall, Windows firewall and AVG free anti-virus should be no problem. Through threads here I have observed three (which doesn't mean there is not a fourth) different causes for your symptoms.

A non-Windows firewall or security suite, including one that was uninstalled but remnants remained.

Incorrect network driver or corrupted driver--hence my above advice.

Corrupted stack or WINSOCK; please do ...

(From a JohnWill post)

TCP/IP stack repair options for use with Windows XP with SP2 or SP3.

Start, Run, CMD, OK to open a command prompt.

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset TCP/IP stack to installation defaults. netsh int ip reset reset.log

Reboot the machine.

Had tried the netsh commands, but tried again anyway, to no avail.
Reinstalled the WiFi driver (Broadcom 802.11g) - twice (with a reboot in between each)

What is interesting is that:
1) https is ok
2) all works fine in safe mode (with networking)
3) http in normal (non-safe) is ok but only for 5 minutes or so

Am in the process of deinstalling unwanted applications but it could be something which isn't program-related that is causing the problem. Am considering a complete reinstall of XP..... Drastic?

Was ok in Safe mode, and also in Clean Boot with everything disabled, but no matter what I re-enabled (even little things) it seemed to not work. So I got bored of trying everything, and reinstalled Windows from i386. Laptop is now cleaner and faster, though something is taking up space on the flash drive (no hard disk) - probably a backed-up copy of Windows from before the reinstall I guess.

So am none the wiser as to what the problem was - some remains of another program I suppose - but the reinstall worked in this case.

Thanks for your help.
