Advantages: Fast, Secure and Efficient Internet Connection Disadvantages: High level of Technical Expertise needed to setup more advanced features
The Cisco 800 Series Routers provide a solution for high speed, secure and above all reliable Internet connection. The 857 model is specifically designed for connecting small office / home office (Soho) networks to the Internet via ADSL (asymmetric digital subscriber line) or "Broadband" technologies. For those of you who know little of Broadband (ADSL), it is a new technology that allows more data to be sent over existing copper telephone lines at higher download rates.
Typically home users connect to the Internet via a Modem, often supplied by there internet service provider. However, this solution of internet connectivity is far from ideal in a mission critical environment. If you don't know what a router is, it is unlikely you need one. However, if you wish to connect to the internet in a fast and secure manner a router is the only ...
Advantages: Very Cheap, with lots of features Disadvantages: Will help with CCNA, but may stuggle with CCNP
I bought one of these routers off ebay to help with my upcoming (Cisco) CCNA exam.
These are by no means cutting edge routers, and are obsolete now as they only support 10Mbps via their AUI (lan) port and support a limited amount of protocols.
The router itself has one AUI port, which when used with a transceiver can connect to either another router or a switch (at 10Mbps); 2 serial ports which can be configured with a routing protocol such as frame relay to connect to another switch or ISP data terminal equipment, a console port to configure the router itself, and an AUX port for modem connection.
Though well past it's sell by date, the switch is perfect to get to grips with Ciscos IOS (internetwork Operating System) and set up simple routed networks in conjuction with other routers and switches.
One thing to be aware of when buying ...
Advantages: Fast speeds, Reliable, Stylish Disadvantages: I had wireless problems, Gets a bit warm, no restart router option in config
, the interface is very straight forward to configure. Main option being the Internet settings for your broadband, which usually consists of a username and password you set up with your ISP (Internet Service Provider). In my case, my settings are bit different as I'm with BE broadband (owned by O2) but even so, I managed to set it up for my ISP without any problems (with some helpful guidance from my ISP). Other ones being Wireless and it's security, and port forwarding, all of which are very easy to set up.
CONNECTIVITY (SPEED / RELIABILITY)
Overall speed of the connection varies from line to line and can be determined by many factors but the WAG160N was giving me around 8Mbit download speeds and a 1Mbit upload. I was getting this on BE?s Be Unlimited package which offers (Up to) 24Mbit download. I?m sure that I would have been able to get 24 ...
