A very solid router but certainly not for amateur By A power home user As a home user, after upgrading my broadband to 6.0mb/s from Comcast, both my netgear and linksys routers were overwhelmed and couldn't cope up with all the activities for the 5 computers, Xbox360 and Slingbox in the house. After researching all the business class routers, including Netgear, Linksys, Sonicwall and others. Finally, I've decided that Cisco is the best product that would solve my problem. Knowing that this is a sophiscated product, I ordered the most basic router without wireless access (hence less variables to configure). Amazon has the best price among all the websites though you certainly don't get any type of technical support from them. As expected, the router requires some professional knowledge to configure. Being a home user, I only changed very few settings through the SDM software that came with the router and it worked very well within my network. The performance of the router is impressive and I am getting the same download speed if I connect my PC directly to the modem. With all the loaded activities in the house, the CPU usage was just around 40%. This router certainly is of professional quality and doesn't even warm up after leaving it on all the time. On the flip side, I found that the user interface (SDM) to manage the router is a little over complicated. It could be much more simplier but is still acceptable. The command line interface through the console port is definitely for professional who knows exactly what they are doing. Through the command interface, you can get almost all status and configuration from the router. I dare not to modify any configuration using the console interface because I'm not sure what I'll be changing. In addition, this router is 4 times more expensive than the ones you can get from local retail stores. Overall, I would recommend this router if you need the quality and performance. Otherwise, stay with the consumer products from Linksys or Netgear. 22 of 22 people found the following review helpful. The most reliable part of my network By Albert K. Lee I am a software engineer who sometimes thinks he's a network engineer too. I run one commercial and one private system from home, with DNS, web, and e-mail service for each, and have a commercial broadband connection through Verizon Online DSL with 5 static IP addresses. After spending days reading specs and reviews of various pro-consumer routers, SOHO routers, and enterprise routers, and after having experienced downright horrible router software and performance from home/consumer routers, I decided on going with a Big Name and it's been a WONDERFUL investment. I am comfortable working on all kinds of UNIX systems, so I am very comfortable with setting things up using a command line through telnet and ssh or by transferring files with scp. This router uses standard Cisco IOS software and there was a real wealth of documentation available on the web, and I was able to get up and running without purchasing any additional books. Once everything was set up, it never needed to be touched, and the router has been chugging along with no hiccups and at full speed. What I had was: - a pool of 5 static WAN IP addresses from my ISP - an internal 192.168.x.x network - web/email/dns/ntp/etc. servers on the internal network - ethernet connections for everything (I have a separate DSL modem) I wanted a router that: - was straightforward for a competent network engineer to configure - could implement NAT the way I wanted to - was totally silent (no fans!) - would not flake on me - had a firewall I got more than I wanted. This router also: - stores its identity/configuration in a single file, which I can archive - supports SNTP (only), so it gets its time from my local NTP servers - does a lot more than I need/use All in all, I am writing from the point of view of an advanced user,
