hi, I have this strange problem on my DSL line with a router (windows 7 OS):
1. when I download a file, nearly always the download freezes, if I hit "pause" "restart" in the Firefox download window then it goes on, until it does it again.
2. very occasionally I open a new firefox window and it will not have a connection, for a few seconds.
3. I can upload a file, for example to facebook, but I can't upload attachments to the webinterface of an email account, either gmail, or my university webmail system, using either firefox, or IE, or thunderbird.
4. I can send and receive emails, but I cannot attach files of 1MB or higher with Thunderbird. Initially I couldn't even attach a file of 30KB, but after disabling my antivirus, killing its process and restarting thunderbird, I started to be able to attach these small files, even if the antivirus is running (I disabled any email protocol checking anyway).
a few weeks ago my XP netbook was able to send attachments via wireless, but right now it's not booting so I can't test it.
Why is the email attachment different to uploading a file to facebook? is there a problem in my router or ISP, or is it with windows 7? how can I check?

See what happens if you disable Windows Firewall (and any other you may have installed).
