Re: [Connectivity] Purchase your own modem = Comcast interfering

Thanks. I just headed to Best Buy and picked one up. In addition to updating the firmware on my routers and killing the DHCP server in my Vonage box (it sits behind the router, not before it), I will have Comcast add the new modem later today and see what happens.

I will return the 6121 back. Thanks again.

EDIT: So I connected the 6141 and seem to be rocking and rolling. However, I discovered another issue. I am using 2 Linksys 54GLs with open source software. They have 10/100 port connections. When I connected my modem directly to my laptop, it switched to 1000 throughput.

The bottleneck is in the routers. I have to get a newer router in the near future as I am losing about 300% of my available download bandwidth when connecting through the Linksys routers. I pull 35/6 directly connected to the modem and 7-8/5 through the routers.

I will probably keep the Linksys as a separate wireless LAN for visitors and work-related projects and use the new wireless LAN for personal surfing and my Vonage service.

Thanks everyone for your assistance.

The custom firmware on the routers will probably have the SPI (Stateful Packet Inspection) firewall activated by default. It allows things like Javascript and specific web sites and such to be blocked. Unfortunately it also demolishes the CPU of all but the most hardy of routers. I have a router with a very hefty CPU. Routing gigabit internally is a fraction of a percent of the CPU normally. The firewall spikes the CPU and network handling and reduces the usable bandwidth tremendously.

Try turning off the firewall feature of the router and see if that helps.
