I live in a three level townhose with people living in units to the left and right of me. My Verizon Fios wireless router resides on the third floor, where the cable connection is. I have that as my office and have most of my equipment hard wired to the router. Problem is when I use my media center PC or laptop on the second floor. I get an extremly weak wireless signal. I tried to attach a new D-link 655 N router to the fios router, and turn off the wireless on the verizon router. It worked really good, but anything wireless could not talk to anything hard wired, and vice virca. I set all the equipment onto the new router and shut off the DNS,DHCP and gateway from the verizon router and only used it as an internet access. Im a systems admin by trade, and Im completly baffled at what could be wrong. Ive since put everything back and dis connected the D-link router and now everything is happy again. But, Im back to the weak wireless signal. Any suggestions would be great and thanks.
