I tried posting in general discussion but have not had luck solving my problem. I have tried searching multiple sites for information and I can't seem to figure it out on my own so I am asking for help. Here is the original post:
I am having trouble with my home network and would like some advice. Currently I am using a DOCSIS 3.0 cable modem, a Juniper firewall, Cisco switch and a linksys wireless router.
Our network is split between two floors of the house. Downstairs is where the internet comes in and the firewall/switch are located. The wireless router is upstairs and is connected to the switch via ethernet.
Currently, the downstairs network is on 192.168.1.1/24 and the upstairs router is 192.168.2.1/24.
My issue is not being able access the two networks from each other. Both have internet access just fine. However, I cannot access computers upstairs from downstairs and vice versa (downstairs from upstairs).
I have looked into subnetting and some other networking basics but really am just confused at how everything works. Should I change the subnet mask on both networks to 255.255.0.0 (/16) or what? I actually tried changing the subnet but it doesnt seem to apply properly. After changing the subnet to /16 on the firewall and router, none of the computers show the correct subnet (they still show /24). So I reset to /24.
I really appreciate any and all advice out there you may have. I can certainly provide more details if needed but I wanted to keep the post as simple and straight forward as possible for now.
Thanks in advance!
