Zyxel P-871m modem and Asus AC87U router setup help

Go to solution

Hi everyone,

 

Another newbie here.

 

I've done a search and can't find anything in the archives that helps me.

 

Due to ongoing issues with my HH5 disconnecting and having poor wifi, I've purchased a Zyxel P-871m modem and an Asus AC87u router.

 

I can't get the DSL light on the modem to light up. I'm guessing I need to achieve this before I do any configuring on the router such as the "bthomehub@btbroadband.com" username input etc.

 

Please could someone advise what I'd need to do to get the modem to connect. There doesn't appear to be any other buttons on the back of the modem apart from the power on/off and CO/CPE switch. I have that set to CPE. There are no setup CDs with it either so you don't access a GUI to set ip up.

 

Just wonder if I'm missing something obvious.

 

Many thanks for any help offered.

 

Guy

With just a quick look at the spec for the Zyxel I'm not sure that it's suitable. Over VDSL only profiles 8a & 12a seem to be supported whereas Infinity is currently using profile 17a.

 

Also it looks more like it's for ethernet over VDSL , ie point-to-point.

 

I think this was an expensive mistake.

It would have been better to go for the TP-LINK N600 TD-W9980.

 

There is plenty of information about it on these forums.

If I'm right about the Zyxel then unless you can return both items (and get the TP-Link) then the cheapest way out ouf this would be to pick up an OpenReach modem from ebay. The HG612 would be the best option.

 

This would work well with the Asus router.

Thank you very much for your responses chaps.

 

I steered away from the Openreach ones just as I thought they were a bit older.

 

As you can tell, I'm not an expert on VDSL etc.

 

I'll see if I can get anywhere, but I may be able to return the Zyxel to Amazon if it's definitely a non-starter.

 

Thanks again.  Guy

Having looked at this a bit more I'm convinced that this will not work for you. It's described as a Point-To-Point modem that works over POTS/ISDN lines.

 

Returning it to Amazon is the solution I'm sure.

I bow down to your superior knowledge Tim as I know nothing about any of the acronyms or technology you mention.

 

I've put a request into Zyxel tech/support and if they don't come up with anything, I'll get onto Amazon.

 

Thanks again.  G
