Having trouble installing a new Asus AX5400 router to replace an ISP supplied one that is 5 years old with poor range. We have fiber, and have been unable to get any kind of router compatibility from my ISP. I moved the cables to the new router and powered off/on the fiber box, and could connect ok to the router with the Asus app, but get no connection to the internet or Ethernet . Any ideas please??? Thanks
 
do you know if your isp provides a dhcp address for the router or if it is static set on the previous?
you could manually set it on the new one if you know it.
also make sure to connect it to the WAN port of your new router

Thanks, not sure about the dhcp, will check on old router and see if can match on new one.
 
Question regarding "have been unable to get any kind of router compatibility from my ISP."

Meaning that the ISP is not/does not provide a listing of supported modems, routers/gateways, or combination modem/routers?

Who is the ISP?

Are you able to access the Asus AX5400 router's admin screens?

This router?

Yes thats the one, and yes can access the router via the app ok. The ISP is Swedish and not massively helpful…
 
On your computer run "ipconfig /all" (without quotes via the Command Prompt.

Post the results. You should be able to do so via copy and paste without needing to retype everything.

As I understand the router's manual you are likely trying to configure the router via an Asus website.

Are you able to directly access the router via a browser on your computer by entering the router's IP address (likely 192.168.1.1) along with the necessary login name and password)?

Note: the default values being "admin" and "admin"only if not originally changed or the router was factory reset by you.

Default settings are provided via physically numbered page 135 of the User Manual.

Internet is not accessible - Page 134.

Reference the router's User Manual to first explore the admin screens and current configuration settings.

No need to immediately start changing things. Simply get a sense of the router's admin functions and features and how the router is currently configured with respect to you network. Wired and wireless.

I have logged into the router and it has a dhcp address

FYI:

Just to help you clarify the problem.

Do not reveal your router's/gateways' public IP address.
Thanks very much:

I have the ISP router, this PC, the new router (on but not physically connected to anything)
 
Unfortunately you redacted the Private IP address used by your network. There are three ranges of IP addresses used by thousands of home and business networks.

FYI:

https://www.lifewire.com/what-is-a-...hen a device such as,with a public IP address.

My Linksys router (gateway) uses 192.168.1.1 which is likely the same as your router is using.

Still your post and "ipconfig /all" information provides some information.

1) Even though the new router is not connected to anything (other than power) it is still present as a wireless device and may be being seen by other network devices. All the more so if it is still at its' default settings. Only one network router should have DHCP IP enabled. If both routers are using 192.168.1.1 then that is a duplicate IP address and networks should have no duplicate IP addresses.

2) The lease time on your current router is only 1 hour. Not an issue per se but likely a lot network traffic occurring as devices continually need to have their DHCP IP addresses renewed. (My lease time is 7 days.)

3) IPv6 is enabled. IPv6 can be problematic for many networks and disabling IPv6 may help with network performance and problems.

4) The DNS Server is the router (likely 192.168.1.1). Many people, including myself, use Googles' DNS 8.8.8.8 and 8.8.4.4

Most home networks use the following connection path (line diagram) where ----> represents an Ethernet cable.

ISP ==fiber==> [ONT]---> Modem [LAN port] --->[WAN Port]ISP Router[LAN Ports]----> Wired network devices and ~~~> wireless network devices.

Make and model modem?

Feel free to edit and correct my line diagram. The diagram is generic and likely needs some correction. Make and model modem?
Note: Physically numbered Page 12 of the Router's User Manual presents a connection diagram.


Walk around and trace the cables and connections present in your network. Do so safely - no climbing roofs, etc. just to get a physical sense of what all is there. Cables going "nowhere" could be problematic.
If you have fiber then an ONT is present:

FYI:

https://stl.tech/blog/a-quick-guide...=The ONT connects to your,and put to good use.

Your router now being the IPS provided router - correct? Do you know if the Swedish ISP supports the Asus AX5400 router.? Most ISP's have some listing of supported routers and if the Asus is not on that list then the ISP probably has no obligation to support you with the problems. (Noted no "router compatibility" in your OP (Original Post). Check the ISP's Forums and FAQs - if any. You might find some information there.)

3 things to resolve:

1) What are the current network connections in place via a line diagram?

2) Is the Asus AX5400 router is indeed supported by the ISP?

3) What are the current IP address and other network configuration settings of the router? Private IP addresses are not a concern.

What you what to protect is the Public IP address assigned to the network router via your ISP. You can discover that via What is my IP or other similar websites. ( Google "what is my ip address" but set the filter to "Past month".)

Overall, the problem is likely a combination of connectivity and configuration.

Barring some direct information that the AX5400 router is not supported, just swap it in to replace the ISP's router, do a factory reset on the AX5400 to set the router back to factory configuration, then use the AX5400 User Manual to recreate the network.

Use the results of your "ipconfig /all" to obtain the IP address being used by the network via the ISP's router/gateway.

For example if the ISP router is at 192.168.0.1, then use that IP address versus 192.168.1.1 for the AX5400. (Subnet mask 255.255.255.0 should be left as is.)

Hopefully just a bit of a "do over" will get the network up and running along with Internet connectivity.

Your line diagram is correct for me.

The router page says my IPv6 is disabled

Router is a Technicolor, Telia WiFi-router Plus v3

Well I tried connecting the new router to the fiber again, and it suddenly is all working.... Download speed and ping only slightly better than the old router but a significantly more stable connection to all devices. No idea why but thank you for your help!!
