know what i did is to change the encryption to back to WEP which i did not really want it since that is why i upgrade the firware of this router (Lynsys BEFW11S4) Wireless-B. More secure encryption. i guess i will keep this router or buy a new one.
(all laptops are getting an IP)
last thing i can do is to reset to factory default and enter the info back?
what you think guys?
