Belkin router F7D4402 v1 ADSL speed is fixed to 1.5 Mbps

Hi,

I need a help to resolve one issue with my Belkin router F7D4402 v1. I have got it recently and configured it without any issue and my internet (ADSL) was up and running. However, later I have noticed that, my internet speed is limited to 1.5 Mbps. whereas; the speed I was getting on my old Linksys WAG200 router was minimum 2.0 Mbps.

I have tried to disable the QoS and other options but no use. But when I enabled the Mac cloning it worked fine. I was getting the speed I subscribed for, but unfortunately, the other devices on my Wi-Fi stopped working. With Mac clone enable, the internet is only available to my PC.

I need the internet on my PC plus all the Wi-Fi devices in my house and along with it my full internet speed, not just 1.5 Mbps.

Can anyone please help to fix the issue?

Thank a lot.

It's not the router - - you up against the limit of ADSL.
