Re: 2Wire Modem Low Signal Strength - Can I have 2nd Router??
You can certainly use a 2nd router as a access point. There are several ways of doing this.
The best solution is to put the PPPoE information (bell's b1 and password) in the linksys router, connecting its WAN port to one the 2wire's LAN ports.
You'll need to possibly remove the b1 from the 2wire's config page. With this setup the 2wire will act as a modem only.
An alternative would be to use the linksys as a access point only (DHCP disabled on linksys - LAN LAN connection between the 2). This isn't particularly recommended because the 2wire is crummy as a router.
