At my edge I've been using an 1841 as an edge router following by a ASA5505 and then to a L3 3750 Switch. My handoff from the ISP (AT&T) is Metro based ethernet (ME-3400 @ 10Mbps). My edge equipment has been working fine for 1/2 year until we upgraded the circuit from 10Mbps to 100Mbps. Now I have bottleneck issues with bandwidth. Can the 1841 and 5505 properly handle a 100Mbps ISP handoff ? (no VoIP just data).
