Have you tried accessing the administration console of the Archer device via PC/Laptop web browser, rather than a mobile device?

 

There are probably more items that need configuring that you are not able to view via  web mobile.

 

This C4000 is a WiFi router and not a modem.

Thanks. No I haven't. Was planning to do that - although it had not occurred to me that the options would be fewer on the app. My house is currently let on airbnb so I didn't have my PC with me. Expected it to be more straightforward!

Where is the embarrassed emoji? Can I simply use the other router as a modem. Or will that hamper the performance of the C4000? What sort of modem do I need - or are they all much of a muchness? (First time I've bought anything that has not been supplied by the ISP).

 

(I did suspect that it was router only but instructions mentioned being able to connect without a modem direct to the wall ...)

You could put your original Asus back in, then connect a network cable from the back of the Asus origin to the blue port of the Archer wifi router (it might need configuring).

 

Existing modem (Asus Origin) <--->Network cable <---> Blue port of WiFi archer.

 

Could give that a go, see how you get on.

@Brix - It does have a modem, sorry I gave wrong info.

 

Maybe the emulator might help you to find out which parts need filling in, since you already have some login details.

I'm still a bit confused to be honest. Are you sure this has a modem? If not, and I use it as an extender with my current Asus DSL N16 , will that hamper its performance? I bought it because when multiple devices connected to my Asus it would often cut out - all connections whether through home PLugs or the router itself would still show a wireless connection but say "no internet". The ADSL light would still be on. Switching the router off and on would usually sort the problem (but not always). If I were to get a straightforward modem, what sort of thing would I need?

@Kevin_Z 

Thanks Kevin_Z. Yes makes sense.

 

How important is the quality of the modem? By that I mean, should the one in the Asus be fine to use with the TPLink Archer - or will the quality / spec of the modem have a lot of impact on the performance of the router?

 

Not having much luck finding standalone DSL router.

 

This is for home use - multiple zoom users, sending large video files, streaming media.

Thanks. Do you mean stable signal to the wall. According to the ISP that is very stable with very few drop outs. Lights on the ASus seem to support this. The problem I have been having with the Asus (and the reason I upgraded to the Archer) is that when multiple users connect, I sometimes lose connection. That is to say, wireless connections between devices and the Asus router remain but show as "no internet connection". Also, wireless connections to Home Plugs remain but they are also shown as "no internet". (Home plugs are connected to the router by ethernet). The green ADSL light remains on. And no connection drop is reported to the ISP.
