I need help because I believe I need to switch out my router. Though my home is all Apple-based product I have recently been given a Dell Laptop for work which I need to sync up with my home network. This laptop is not acknowledging the networks currently in my home. This PC laptop will not work on the apple network (Time network) and the current linksys router. My technology people believe the linksys router could be out of date relative to the wifi requirement of the new work PC laptop. They want me to have a WPA or WPA2 router. Is there one router that is better than another which will be able to work seamlessly between the current Apple models in my home as well as the new PC laptop? I would like to get the new router before you come over so you can set it up properly to work with all the computers I now have in my home. Please let know your thoughts on this matter.

There is nothing wrong with the routers you have in your home.  They are all capable of using WPA and WPA2 security.  I feel strongly that this issue can be resolved without purchasing any additional router.  802.11 is a standard across the industry and the manufacturer of the router or PC have no bearing.  There are several flavors of 802.11.  B, G, and now N.  it may be best for us to first look at what the real issue is for if we replace the router we may be likely to experience the same issue.  I've found more often it is the fault of two conflicting peices of software on the Windows machine both of which are attempting to control the wireless card on the laptop.  Windows can control the card and that is preferable however, some computer manufacturers will include a second piece of (poorly written) software that challenges windows for control of the wireless card.  This is far more often the case rather than incompatible routers.  As a matter of fact, in my experience, I have never encountered an incompatible router.
