Hello,
I have the following product:
Code:
> sys version
Router Model: Vigor120 v2 Version: 3.2.6 English
Profile version: 3.0.0 Status: 1 (0x273d3001)
Router IP: 192.168.2.1 Netmask: 255.255.255.0
Firmware Build Date/Time: May 4 2011 18:33:00
Revision: 27022 v120
ADSL Firmware Version: 321311_A Annex A
I'm an O2 LLU customer and I've noticed that the Vigor 120 connects at slightly slower speeds than other routers I've used, including the O2 Wireless Box IV and a NetGear DGN2200. I usually get over 19Mbps DS from those, while the Vigor 120 connects at around 17.8Mbps:

DSLAM CHIPSET VENDOR : < BDCM >
I'm wondering if this has something to do with the fact that O2's LLU DSLAMs use Broadcom chipsets and so do the two routers I've tried, resulting in better interoperability.
I'm aware that there are multiple firmware images available for the Vigor 120 with different modem codes. Would any of these provide better interoperability and connection speeds to a Broadcom DSLAM?
