I have my modem plugged in downstairs to a D-Link DIR 868L which provides more then enough internet connection for the downstairs, but not the upstairs. I ran a 50ft. Ethernet cable upstairs and plugged it into the Ethernet port 1 on the 868L downstairs and into the WAN port on a Linksys E2000 upstairs, I am getting great speeds now upstairs, but my security cameras that are plugged into the Linksys upstairs can't be connected to through my iPhone app anymore. The camera system is a QC40196. I tried to find the solution online, but honestly my brain just gets all foggy trying to make sense of what people are talking about.. I'm hoping maybe someone can give me a step by step solution?
