Hung TCP - Reinstall?

22 Jan 2009 4:54 PM

Nicola Taranto

I have PC1, PC2 on home network wired/WiFi with access point up to 7Mb , same
HW/SW i.e. XPSP3 up-to date, IE8, >1Gb RAM, >1Ghz CPU.
Share printer and folders activated and well done sharing.

With PC1 I can upload pics over Internet up to 1Mb;
With PC2 I can upload only pics up to 100kb. The PC2 starts uploading large
files (>100kb) but, after a lot of time, upload crashes.

I suppose a misconfiguration of TCP on PC2 but I don't know what.
I've tried the following in abuot 7 day tests:
- disable antivirus and firewalls too;
- connected PC2 with wired cable to router, instead of WiFi;
- reinstalled NIC and WiFi cards;
- deleted cookies and all temporary internet files;
- enabled cookies and script on IE;
- used IE7 instead of IE8b2

but uploading from PC2 don't go on.

What appen? Can anyone help me?

Thanks

It could be a MTU setting problem.

Try running the Tweak Test at:
<http://www.dslreports.com/tweaks>
and see what is recommended.

Sorry but i think that isn'i MTU problem.
I've tried with your suggestions setting MTU according dslreports but
upload dont got goals.
I discover uploading trouble only over my profile in ORKUT no in my profile
over Windows Livespace.
Tests with Dslreports sends 1024000 bytes ok, I got error uploading up to
100000.
I haven't any to think.
Thanks
