Before moving to Xilo I bought a Vigor 120 v2 as I was expecting to be placed on an Infineon DSLAM, but according to my modem, I'm on a Broadcom DSLAM.
I've tried a couple of Broadcom modem/routers (Belkin F5D7633-4 on firmware 1.00.25 and a Technicolor TG582n unlocked using this method) that supposedly support annex m, but the both of them sync at a max of around 13.5mb down and 1.3mb up. This is quite low considering I synced at 18.5mb down/1.4mb up on BE (uncapped annex A).
The Vigor 120 v2 syncs at about 12.5mb down and gives a better upstream sync at 1.9mb, but I'm wondering if I can get this higher by matching chipsets, something which worked wonders when I was with BE and Sky.
I'd appreciate recommendations or advise, e.g. maybe there's some settings I could change via telnet on the two Broadcom modem/routers? If I need new hardware then the most I'd be willing to spend is around £40 (I don't mind buying second hand), I may be willing to spend more if the sync speed is proven to increase significantly in similar conditions to myself.
The new modem or modem/router would have to allow my RT-N16 to connect to it, the Vigor 120 v2 only allows me to do this as it can translate PPPoA to PPPoE, a feature that I believe is quite rare. I don't mind having a double NAT if the increase in sync is noticeable, in the past I've only been able to connect by putting my routers IP into the modem/routers DMZ.
Some info I got through telnet on the Vigor 120 v2:
