I can ping any address on my workgroup
I can ping my router (default gateway) but the first packet always takes much longer than the other sent packets e.g first packet takes 48ms and the rest only take 2ms

I cannot ping my own IP address
Removing Avast, ZoneAlarm and disabling Windows Firewall make no difference
Flushed DNS doesn't work

Web browsers perform slow and often don't load, I have to refresh or come back later
Downloads time out after a few minutes
I have to use a download manager to get files larger than a few megs
My IP Address is manually configured and DNS settings were provided by my service provider.

Been at this for a few days without luck and really don't want to reformat. Any help will really be appreciated

Thanks

Just you let you know, I could not ping localhost successfully as well, always packet loss between 50% and 100%. However, pinging my router, pinging with IPv6 (ping localhost -6) worked fine. Internet access worked, but not really speedy.

Disabling Windows firewall and Zonelarm (Free) Firewall did not solve the problem, but uninstalling did.

It is one week ago I downloaded it, seems they have still issues here.

I also noticed the debug files in Windows/Internet Logs growing rapidly (200 MB / hour).

Somebody with a recommendation regarding a free firewall?

Cheers,
Dulli

Comodo Firewall is free and is recommended by many geeks here.

Hi Dinesh,

Thanks for this tutorial. I quickly established that my AV (which I have been using for some time without a problem) was the problem. I have now replaced it with MSE.

Great Job.

Hi Dinesh,

Thanks for the help you provided for some reason I cant still access internet... I can see my wireless settings and when I ping I get reply from default gateway bu not website like Google or yahoo...

It says cant find host

I have tried everything, including installing new Intel wireless driver for my lenovo t61 laptop...

please advise...

Even when I connect using modem directly still cant access internet... this happened since I downloaded Itunes 9 on my laptop ... I cant think of another reason... also I had a freeware spyware program called spyware terminator which was blocking few good services, but I have uninstalled that as well...

please help

Regards
Deno

Hi Deno, its not your PC's fault. I'd suggest you to contact your ISP and check with them for any known outage in your area.
