Origin Broadband - Asus DSL-N14U

RS1986:
Hi all,

I'm new here on the Forum, I stumbled on this site as I'm trying to correct poor line speed and CRC errors with some help from the advanced tech staff at my new ISP Origin Broadband.

Thanks to the reading I have done on this site and what I could search through the forums I have gleaned enough information to identify the fault on my setup which is essentially the router, I have disabled all advanced DSL settings which causes a very high rate of CRC errors and Downstream fluctuations but I'm still having CRC errors which I've basically read is down to the ASUS equipment.

As it stands now I have had the DLM Disabled on my line and am looking to buy a standalone modem to provide a more stable ADSL2PLUS connection and use my old BT HomeHub 5 for Wireless networking as the ASUS doesn't provide a 5GHz band on WiFi.

Based on the following information could anyone advise which modem would be best suited to pair with my line?


--- Quote ---DSL Modulation   ITU G.992.5(ADSL2PLUS)
ANNEX Mode   ANNEX A
DSL Exchange(DSLAM)   Globespan

MAX Rate   [DOWN] 4544 kbps [UP] 956 kbps

Also as I understand it, please correct me if I'm wrong, Globespan means that there is an NEC chipset on the exchange?

Many thanks for the Education KITZ! :thumbs: :clap:

Welcome to the Kitz forum.  :)

Looking at the information you have provided it is similar to that of my own circuit. I find that a device which uses a Broadcom chip set will perform best and so use a ZyXEL VMG1312-B10D (a modem/router), configured for G.992.3 (a.k.a. ADSL2) rather than for G.992.5 (ADSL2+).

No two circuits will behave exactly the same. Hence it is a trial and error process as to which modem/router would be the best choice.

Thanks for your input burakkucat! I had been looking at ZyXEL, so I will check out the model you have suggested  ;)

burakkucat:
I will point you to a different thread and suggest that you take a look through the devices listed in the very first post.

RS1986:
Fantastic mate, once again thanks a lot!

I had looked at that thread but got a bit confused with the VDSL bit so to make sure I thought I'd ask just so I know i'm on the right path.

Enjoy your evening :)
