i'd like to replace my usb adsl modem with a combo modem/router that i'll buy elsewhere other than my isp, but how can i determine that it will work with my isp, cuz from them i'll get only the modem (not the router) which is attached to an ethernet service plan should i take its modem)

any ideas on the specific modem/router i should buy based on my modem & isp info (if it matters):
usb adsl zyxel prestige 630 from cable & wireless(non-us isp from panama)

Replacing a provider-supplied DSL modem with a third‑party combo modem/router is usually possible, but only if the new box supports the same line technology and connection method the ISP uses. is right that many problems come down to settings, yet some ISPs use provisioning, ATM encapsulation, or VLANs that retail devices must explicitly support.

Before buying, get these exact details from the ISP:

  • DSL standard required (ADSL, ADSL2+, VDSL2) so the modem chipset matches; see ADSL.
  • WAN authentication/encapsulation (PPPoE, PPPoA, IPoE/DHCP or static). Note that PPPoA uses ATM and is not handled by all Ethernet-only routers; check support for both PPPoE and .
  • ATM parameters (VPI/VCI) when ATM/PPPoA is used.
  • Whether the ISP requires 802.1Q VLAN tagging on the WAN and the VLAN ID to use.
  • Subscriber credentials, static IP/DNS (if any), and whether the provider binds service to the modem MAC or provisions devices remotely.
  • Whether the ISP will put their modem into bridge mode or support a third‑party device.

Choose a modem/router that explicitly lists the DSL standard and encapsulation you need, exposes ATM/VPI/VCI and VLAN settings, and offers firmware updates. Buy from a seller with a return policy so you can test on your line. If the new device won’t sync, verify physical line, modulation profiles, ATM/VPI/VCI, VLAN ID and encapsulation; ask the ISP to re-provision or update the registered MAC. If the provider refuses to support third‑party gear, keep their modem as a fallback.

I use a comtrend router and it works great. Im not realy big into the workings of the internet but from what I understand they will all work its just the settings in it that you will have to change. I have used sever diffrent routers and modems over the years and never had to worry about compatability just the settings. Remember thought that if your provider is not familiar with that router or modem they may not be able to offer you tech support on setting it up or trouble shooting.
