Hi, I have a WRT54GS. MAC address filtering is "enabled" and set to "permit only" for wireless connections. However, I tried with another laptop, and got connected for 20 minutes "for free", I believe this should not be allowed. After 20 minutes I was kicked out, but then I could reconnect again. I noticed that it also seemed to cause IP conflicts on the other computer... How to set MAC address filtering _really_ "permit only" those whose address is listed in my config? (I don't want to use WAP, WEP encryptions because I also have a couple of Linksys signal amplifiers (repeaters) connected to this router, and I just wanted to config those easily with a press button, instead of software config.) My firmware version is: v1.50.6, Feb. 17, 2006 Thanks for your help!
