5 out of 5 eggsDecent Cisco Entry Level Router

Pros: Its a stable cisco product that doesnt cost much (in terms of cisco)

Cons: Very restricted in terms of almost everything (although your clearly told that so im not going to knock an egg)
its 10/100 on the Lan/Wan so I would say its a good Small Business gateway router or something to be used for your VPN communications.
You will need to purchase a smartnet contract (very cheap for this device) to recieve IOS updates.

Other Thoughts: I bought this to help me prepare for my CCNA. It gets the job done, although alot of the advanced features in the CCNA do not apply to this entry level router.

Please stop giving this router low reviews because you dont know what your doing with it. If you want a plug and play router, they make Linksys for a reason, stop complaing that you have to configure it from the CLI. The problem lies with the purchaser for not researching the product. If it functions correctly, and works as advertised then you cant give it 1 egg since you dont know how to use it. Thats like buying an airplane and then complaining about the equipment because you dont know how to fly...

4 out of 5 eggsRock solid

Pros: Can handle 25 or more people doing everything you can think of, multiple site-to-site and client to site VPN connections, play very well with the VPN client built into Macs, iPhones, & iPads. It will do VPN with practically whatever the other side has. I get virtually no "it ain't working" call backs on these things. The only thing that takes them down is a power outage. I personally much prefer the Cisco style of firewalling & NAT over SonicWall and Juniper.

Cons: You pretty much have to get the $50 subscription to Cisco (usually from another popular retailer of Cisco products) for this and pretty much any Cisco product in order to get firmware updates and the "Cisco Configuration Professional" package. It doesn't come with the "Cisco Configuration Professional", which is pretty much a have-to-have as the builtin web-based configuration utility doesn't configure any of the features that you would buy this for. If you want to be "hard core" you can use the CLI if you like carpel tunnel. It's gotten better in the last year, but they can have badly buggy firmware out of the box and you might have to back-date the firmware.

Other Thoughts: If you don't make a living doing complex networking, don't bother with these or anything other "commercial grade router". You need to spend a lot of quality time figuring out the gotchas & bugs in addition to "advanced" networking concepts. SonicWalls, WatchGuards, and Junipers can be just as bad or worse (I've seen Juniper be stunningy worse in terms of bugs), so just call somebody.

1 out of 5 eggsCisco 800


Cons: NO software;
Docs comes with it;
Illustrations do not match the actual device;
Links on the Docs, broken and not labeled;
You find 1 exact document to help you setting this up specifically written for this device on there website;
STONE AGE Serial cable, I had go buy dame 9 pin serial card to talk to the dumb thing;
Setup line by line for a 860 but this 861. Reboots; then want too on command line on serial cable start over. The GUI CCP tries to configure it but THAT fails too.
Last 861 got worked with GUI that suppose to work with 860 but this 861 not.

Other Thoughts: WASTE OF MONEY.

2 out of 5 eggsDifficult to configure

Pros: Cisco name and proven reliability

Cons: Confirm other reviewers. This is a difficult product to configure. Not for the non-technical home user. CP express web interface appears to simplify configuration but so far no luck in getting it to work. Instructions with the unit not much help.

Other Thoughts: Why does Cisco have to make these routers so difficult to configure? Why should I have to be a CCNA to make it work? Looks like CISCO doesn't have enough competition.

5 out of 5 eggsAwesome router for small or home office

Pros: Solid, silent, feature rich - has DHCP, DNS Server, NAT, port forwarding, firewall, etc.

Cons: *** THIS IS NOT FOR THE NON-TECHNICAL *** If you don't at least know what CCNA means, don't bother getting this, you won't understand it. The web interface (CP Express) refuses to work for me in any browser on both Linux and Windows - had to do all initial config with a serial cable, and future updates to configs over SSH.

Other Thoughts: If this is for home use, make sure you're a high-level geek.

5 out of 5 eggsCISCO = Great Router

Pros: This is a great router for the money if you are looking to learn the Cisco IOS for CCENT/CCNA studies and is a great home router. This router will give you many years of great service without having the worry needing to reboot once or twice a month. Over the past 5 years I have purchased the 3 of other leading brands that last for about 2 years or until the warranty expires.
Cisco has a reputation for rock solid/ high quality products, and also you get what you pay for....period.!

Cons: None
