Router and gateway (modem) manufacturers continually change the firmware and hardware revisions on their devices.
This means that while we confirmed the recommended routers function successfully on customer's sites, we cannot guarantee that all firmware versions and hardware revisions of the models we have documented in our knowledge base will work correctly.
We continue to update our recommendations as soon as customers encounter new problems with specific firmware and hardware revisions of specific router models, but we cannot guarantee the information below will always be up-to-date with the latest router's firmware and hardware compatibility.
For initial setup please contact router manufacturer or your Internet Service Provider (ISP) because they include technical support as a part of the cost and they have specific information that can help you get up and running faster. However, Smarsh Hosted Services is here to assist you to the best of our abilities to provide a worry-free experience when making this change.
Settings from the old router will need to be moved to the new router manually. Common settings include:
- The wireless network password and name,
- Port forwarding rules,
- Firewall rules,
- Network ID / VLAN settings,
- VPN settings,
- DHCP scope,
- And much more.
If you do not move these settings, it can cause many problems on your network, including:
- Being unable to print,
- Clients being unable to connect to your company website,
- Being unable to send or receive emails,
- Being unable to remotely connect to your office computer,
- And much more.
A note about ISP provided modems:
In general, most ISP provided modem/router combination devices are problematic with Hosted PBX solutions because the ISP's custom firmware limits the level of configuration available to the end user. Some ISP provided modems have a NAT firewall that interferes with SIP and breaks the call signalling that is critical for the Hosted PBX phones to work properly. Devices that are listed "incompatible" MUST be either replaced with a serviceable modem OR placed into NAT passthrough (a.k.a "bridged") to a serviceable router. The serviceable router is purchased separately.
When an ISP bridges their modem you will need to disconnect all of the devices that were connected and move them over to the serviceable router. In other words, after the modem is bridged the only thing that should be plugged into the ISP modem is the serviceable router. If you do not have enough LAN ports available on your serviceable router you will need to purchase an ethernet switch to support all of the devices on your network. Note that the methods used by the ISP to bridge the modem vary from company to company and Smarsh Hosted Services cannot bridge the modem for you.
