cisco 2561xm router with WIC1-adsl card and NM-16ESW switch
I recently had to temporarily disconnect my above router for a few days and replace it with a cheap plastic home router and was embarrased to discover my adsl broadband speed shot up 45% with the cheap router. With the cisco 2651XM I always got a max download of 400kb/sec but with the cheap router I was getting 580kb/sec. Clearly something is wrong with my cisco config, I put this down to the mtu setting, which in the cheap router wasn't shown but set to auto. I've tried different mtu settings in the cisco router (including 'no mtu' but never get more than 400Kb/sec.
My isp indicates optimum mtu is 1500 but that doesn't produce any speed increase.What can I do here to get the cisco router working to maximum speed?
I am not sure I am saying correct or not but if you can try :

Turning off the IPS (intrusion prevention system
you have IPS enabled on the router. Leaving the firewall ON, try disabling the IPS feature completely, saving, and then power cycling. Because IPS strips each packet and looks for malicious code/abnormalities, it has the potential to create a lot of overhead.
thanks for your response. I'm only novice-level with this cisco router but I think I don't have any IPS enabled. Attached is a pdf copy of my running config. If you can see any wrong settings in there that could affect adsl full speed I'd be grateful to know.
I did try but it made no difference. For a test I took the adsl wic card out and stripped down the config and plugged the cheap plastic router into the NM-16ESW switch but the best I could get was 470kb/sec which is still 100kb/sec down from before. The problem must be in the switch or some config setting and this slowness only happens with adsl traffic, it doesn't happen with traffic between machines on the LAN. If I transfer data on the LAN I get 12Mb/sec easy.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
