Cable Forum - View Single Post - Virgin limiting download speeds intentionally

If you've a large number of connections it can saturate the modem/router/TCP-IP stack, but that doesn't look like the issue here.

Filehosting websites do cap upload from their end, unless you spring for a premium account, and even then they can change rates on downloads in order to spread load on their servers. Check the FAQs on the sites would be the first port of call.

If you're seeing packet loss, that can (and does) cause slow speeds. I'd recommend running an extended ping to a known good server. The command for that is ping -n X website.address, where X is a number greater than 4. I like to use multiples of 25. Your choice. I'd also recommend a great wee command called pathping, which is half tracert and half ping - it identifies every hop between you and the target website, and then pings them. It can tell you where the packet loss creeps in.

I'd also recommend posting your modem signal levels if you've got an issue. You can find them from modem configuration page, the old 192.168.100.1, all that's needed is the SNR, up (and down) stream power levels, and maybe the frequency. Don't post the MAC address, or your IP address, one of the admins will just have to take it out.
