TP-LINK TD-W8901G Router

this is because your modem is out dated your better off getting a new one

If you are paying for a downlink speed of 384 Kbps you should be getting at lease around 300. First bypass your router - connect your cable/DSL ethernet line directly from the modem to your PC. Go to http://www.auditmypc.com/internet-speed-test.asp run the speed test and see what your download speed is.

If it's less than 300 call your service provider & ask them to check out your line. If they say that you are getting 300 Kbps or more, you have a problem with the ethernet card in your PC. Replace it.

Of course, if your speed is OK when you bypass the router, you have a router problem. Contact the manufacturer or replace it.

yeap it should be the firewall, here is the manual http://www.tp-link.com/resources/software/201161017075118.pdf
think this should help you.
But if you want my expertise, make the tp-link as a router and vdsl just the internet line. connect it to router wan and buy a switch for all your devices.That should be the safest and smartest way.

Testimonial: "Hi, I've finally found some time to test the dissabling the FW and I can say that in my case it helped. I can see now from TP-LINK IP cameras connected to the VDSL modem/router. Well done guys, thank you for your help. Kvinar"

The line speed is controlled by your internet service provider, not by your router. If you have something like AT&T as your internet service provider, then they sell 3 or 4 different line speeds or packages. The cheapest will get you the slowest line speed. So if you have a 300mbps router but you purchased AT&T's cheapest line speed it will never allow you to do downloads, uploads or streams at 300mbps. You gotta Pay to Play. :)
