Next, CoverAll Insurance Company needs to securely install eight Linksys WRT54GX4 Wireless Routers, which include a 4-port switch that supports the 802.11g wireless networking standard and also has VPN pass-through as well.
The WRT54GX4 needs...
The WRT54GX4 plugs directly into the existing CAT-5 cabling already installed in the company today. As of May, 2008 the WRT54GX4 sells for $126 each, totally $1,008. As the WRT54GX4 is the strongest wireless router that Linksys manufactures, the company's workers will be able to use wireless access throughout each of the eight floors of the company. The following table provides the specifics of the WRT54GX4 wireless router.

Pricing for T1 service vary significantly across broadband providers. Covad offers full T1 connection support at $369 per month with a switch included. It is more economical for CoverAll Insurance Company to purchase the Cisco Switch mentioned earlier in this paper. Analysis of T1 services provided a range of $365 to $775 for a two-year contract including a Service Level Agreement (SLA) for 99.999% uptime. Pricing is negotiable as many of these vendors include the cost of a high speed switch as well.
