This "wireless security system" is some device plugged into one of the router's LAN ports. Correct? If so, the firewall or AV in the PC has no influence or effect on other devices plugged into the router. Does this "wireless security system" have any documentation?
How about providing more information on this system?
I have an older D-Link DGL-4300 wireless router, I've purchased a wireless home security system and can't seem to get the 2 connected. I've tried resetting the router & modem (powering down & waiting from 1-5 minutes), and my router just won't read the port that I've plugged the security system ethernet cable into.
I think the problem is my firewall but I don't know how to set it to allow the router to read the port that I've plugged into, or it could be the firewall that my anti-wirus has or possibly both.
My equipment is Comcast cable, router (as noted above) and a D-Link DCM-202 modem, Windows XP 3, and Norton anti-virus. Now I also have my phone through Comcast and it has it's own modem.
Any help is greatly appreciated, I can't believe I'm the only person to ever have this problem.
Thanks to all who respond.
