We have a netgear51 router with 3 laptops, 1 iPad, 1 Kindle fire, and five smart phones connected to it at any given time. We also use Vonage as our landline phone which is connect also. It seems the more devices that are trying to "use" the router the more we get kicked off. And if even one device is online, the Vonage phone system cuts out.
Is it possible we need a bigger/more powerful router or could it be the box from our ISP is too old or not powerful enough.
Thanks Deb
