Not knowing my Linksys Wireless-B- Broadband Router Model BEFW11S4 and PCI Wireless- B- Adapter Model WMP11 were not secure, all of my applications were working just right...When I was told to put a security password on it to protect all my personal files.. Now none of my applications or programs work at all...I have a Multi-Pool Rate Booster and several other rate boosters which will not work at all. I will load the pool players names ...they sign in ...then only "connecting to yahoo rooms come up...but they do not connect "These applications r to boost the score in pool..(from yahoo all Legal)..I have worked on this for several weeks and can not figure it out...Please if someone could help me I would be forever grateful..Something is blocking the signals going out....I'm new and learning ...Thank You Janie
