Quick summary tied to the thread: reported a Linksys router not talking to a Telecom SpeedTouch modem. As noted, the exact model numbers and whether this is an ADSL/DSL link and which ISP is used will change the correct steps. correctly flagged that two devices trying to be the network router can cause problems — that is one likely cause among several.

Stepwise checks that fix most Linksys/SpeedTouch problems:

  1. Verify the SpeedTouch alone can get online by connecting a single PC to it and confirming web access or seeing the ISP authentication prompt. If the modem needs ISP credentials, either the modem must hand off a public IP (bridge) or the Linksys must be configured to perform the PPPoE/ISP login.
  2. Confirm physical wiring: phone/DSL line to the SpeedTouch, Ethernet from the SpeedTouch to the Linksys WAN-facing interface (or into a LAN port if intentionally using the Linksys as an access point).
  3. Reboot in order: power the modem, wait for sync, then power the router. After the router is up, check its WAN/status page to see whether it has a public address or is showing the modem/router address (a clue to double-NAT).
  4. If the ISP tied the connection to the modem's Ethernet MAC, use the Linksys MAC-clone feature or temporarily power-cycle the modem so it forgets the previous MAC.

If both units are doing NAT and you cannot change the SpeedTouch into bridge mode, use one of these approaches: let the modem stay as router and put the Linksys into access-point mode (turn off its DHCP server and use a LAN-to-LAN connection), or put the modem into bridge and let the Linksys do routing. Also check for firmware updates and reserve factory reset as a last resort.

Useful diagnostic details for a clear next step: exact model numbers of both devices, whether a direct PC-to-modem connection gets online, what the router WAN/status page reports, and the modem/router LED patterns.

There may be an IP address conflict depending on what ports you're connecting them with you need to change the IP address or subnet that they're on. If you're connecting the DSL modem to the WAN port on your router you need to log in to the router and put it on another subnet by changing the ip address from to (as long as the second to the last set of numbers are different you're O.K.), if you're connecting to a from the DSL modem to a LAN port on the router, you need to disable DHCP on the router and make sure it has a different ip address on the same subnet. For example IP address of modem ip address of router 192.168.1.2. Make sure you disable DHCP on the router or you'll have 2 devices trying to hand you an IP address.
