Recently I switched my Internet provider from Comcast to Verizon DSL, and one of the first things I did on the router was to change the default wireless DHCP IP subnet. the reason I did that was because I cannot connect to our company VPN using the default 192.168.1.x subnet in the Verizon DSL modem. this is one of the reason we phased out VPN from our company by the way, because the 192.168.1.x IP subnet is the most used in home routers, and since we switched the subnet mask to 255.255.254.0 on the network at work because we were running out of IPs and needed to extend the IP range, since then people could connect to our VPN using the 192.168.0.x or 192.168.1.x IP subnets.

Remember that if you are setting up a static IP address on your home router, you need to get the IP information from your Internet service provider (ISP) or get it from your current router configuration, but keep in mind that ISPs assign IP addresses dynamically, so your actual IP address could change anytime. now, if you are assigning the static IP address from your network, then make sure is in the same subnet mask as your other devices on your network, otherwise the router…
