WIFI Issues

[sandra9968]

We have had Verison DSL for years and have had the same modem and router for years as well.  We each have a phone, daughter has and iPod and Nook and we each have a laptop.  If we have 3 or more devices going at the same time no one is able to do much, the connection is very slow and on my Droid phone, I will have to turn off the WIFI and then turn it back on for it to connect at all - at times I have to do this when I am the only one using the WIFI.  Is there a change to a modem or router that would cure this problem?  Is there an upgrade of some kind from Verizon?  I am not techy so I appreciate being told in simple terms what to do.  I have looked through the forum, but when I start seeing all the technical ways to fix something I am lost.  I need it simple.  Thanks for any help!!
