My old trusty Linksys WRT54G finally went to the great recycling bin in the sky after 7 years of faithful service. Goodbye old friend.
Got a new Cisco Valet Plus, model M20. I set it up and all seemed OK for a while. Gradually page loading became excruciatingly slow. I have a 6Mbs cable internet service and the speeds I was seeing for page loading were near dial-up. Yuck. I did the usual reboots of the modem and router and things seemed to be better after a reboot but soon went bad again. Googled for a bit and came up with the same issue suffered by others. One recommended fix was to turn off the "Safe Web Surfing" feature in the router. BUT...you can't get to that via the usual 184.108.40.206 route! I had to go to my windows machine and plug in the super special Cisco Connect USB key and run their windows software to toggle the Safe Web Surfing feature to OFF. Page load speeds returned to normal immediately. The intent of the Safe Web Surfing may be noble, the execution....not so much. And forcing me to use windows to fix the issue...not cool. Of course, YMMV. Just my $0.02.
