TiVoInternetConnectionFilter: Help me troubleshoot my internet connection's disconnections. For some reason when my computer is plugged into the router (which is plugged into the cable modem) the internet connection drops every 30-45 minutes. When it is wired directly into the modem, all is well. My TiVo connects wirelessly to the router. Is my favorite TV accessory causing my internet woes, and how do I fix it? [more inside]

How can I troubleshoot my Mac's ADSL connection? A few weeks ago my download speed suddenly dropped to about 4kilobits/sec after I tried to set up a firewall. I then turned off the firewall, but the speed hasn't returned. I'm running Mac OSX 10.3.4 on an eMac with 1GHz processor and 1GB RAM (confirmed intact by profiler) on a simple ADSL router (YahooBB, the leader in Japan) with an ethernet hub. Interestingly, upload is fine at 500 kbps, and my older slot-loading iMac 350MHz is zooming along fine on the same connection at 1150kbps download speed. TCP/IP settings are simple, DHCP auto-assigns the IP.
