Cisco SA 520 Wan Performance Issues

Hi,

First sorry for my bad english, i hope you guys can read it and help me.

I bought a Cisco SA 520 Device, and i got a XS4ALL Viber 100/100 line thats on the wan interface.

This device is realy on the edge of my network. its my "router".

The newest firmware was installed on the device and its got factory default settings.

Everything is working as aspected, but many speedtest at different servers shows me a performance issue.

If i test i got 69 Mbits through the line. If i switch to an older firmware it shows me 79 Mbits through the line.

Its not a performace issues on my outside line because If i install the Fritzbox router that i get from my ISP i got full performance.

Do you guys have any idea's how i can get more performance ?

Kind regards,

Aldert Smits

Cisco SA 520 Wan Performance Issues

I'm having a similar problem though I haven't tried a different firmware level.

Our connection is supposed to be 35Mbps down and 5Mbps up but we are only getting about 15x3.5.  After a reboot I got the full bandwidth for a short period of time but then it reverted back to 15x3.5.  I tested the line and it will consistently deliver 35x5, just not through the SA520W.  I really regret having bought this device.    I should have bought the ASA5500 series...
