1941 internet speed

[ciscoreg2]

Hi;

I use 1941 connect to internet via PPPOE, I found my internet bandwidth was about 30-50mb (3-5 mbp/s), but from ISP my bandwidth was 100m.

I test directly connect to modem use computer speed was 100m. So what's the problem of my router?

So what's the problem of my router?

The problem is that the router can't handle 100 Mbps worth of traffic.   (Go HERE.)

The most this router can do is about <40 Mbps.

But i use Giga interfaces to connect to modem, modem lan interfaces speed is 100m. still cannot reach 100m?

still cannot reach 100m?

100 Mbps?  No. 

50 Mbps?  Maybe.

before I tested its speed is OK. recently I erase startup-config and speed is becoming slow down.
