SA520W > Internet slow or stoped - when copying files in LAN from PC to PC

SA520W > Internet slow or stoped - when copying files in LAN  from PC to PC


Hi Folks...

when I copy some files in my network from one to another PC, browsing speed is going to nearly zero!!!! :-(

Also sometimes when I upload soemthing, it sometimes is the same behavior.

We run PPOE with two dsl Lines....

I ndont have some special traffic shaping... only all IP addresses over 100 use one wan port... all others the other port...

but why should WAN get slower, when LAN is trafficing heavy??!?!

I have:

Small Business Pro

Security Appliance Configuration Utility


Product ID:  SA520W-K9
Version ID:  V01

Primary Firmware Version:2.1.71
Secondary Firmware Version:1.1.42

This is my first Cisco produkt and to be honest, its quite complicated for me

Any other info i need to provide? what test steps shoulöd i do? THANK you all in advance!

SA520W > Internet slow or stoped - when copying files in LAN fr

a friend says...i might have a bad cable.. that looses too much packets... that have to be requested too often.. that slows the complete router?

might this be something?

I quote from another thread what i will do now:

Turn on logging...

Administration -> Logging -> Logging Facility and Severity

Turn on Debugging level for System, Kernel, Network, and Firewall.

Can you get a sniffer from Administration -> Diagnostics -> Packet Trace, do this on the WAN interface.

Use that and recreate the issue with the web pages.

Get the sniffer and the logs and post them here please.

any comments from you @LL ?
