I'm not sure how to work router systems that much, since my router config that's up now was setup by someone else.
Right now I'm running a couple buffalo routers (G54 Airstation) that are a year or two old. The main router is connected to the wall in one room, which bridges to another router around 55 feet away (some walls in between, maybe 3 or so). Both routers are wireless, but I have troubles keeping a decent constant signal.
I'm not sure if this is a router problem or not, but online streaming content takes a while to load and gaming is unstable (connection stops every once in a while).
Would I fix these problems with a new pair of routers? What type of security would I need when setting up these routers, and how do I exactly bridge the routers together?
