Seriously, avoid "fibre-cat".
Why? Because of claims like this.
Unlocked BT Openreach Modem ECI/r [v3] - VDSL 2 /FTTC/Infinity-Superior to HG612
How in any way is it superior?
Good grief! £80 for an ECI?
I dont know enough about the following subject but I note his claim of ReTX following the output
nReturn=0 nDirection=1 bTrellisEnable=1 bBitswapEnable=1 bReTxEnable=1 bVirtualNoiseSupport=0
However I know with the TPlink TDW9980 (same chipset) needed the following to be fully compliant with g.inp (As you will recall I was in close communication with TPlink when it came to light that the TDW-9980 originally only supported g.inp downstream. This is output from the TDW-9980 after the tplink fix to support g.inp support in both directions.
nReturn=0 nDirection=0 bTrellisEnable=1 bBitswapEnable=1 bReTxEnable=1 bVirtualNoiseSupport=0 b20BitSupport=0
nReturn=0 nDirection=1 bTrellisEnable=1 bBitswapEnable=1 bReTxEnable=1 bVirtualNoiseSupport=0 b20BitSupport=0
ejs is a far better man than me to be able to say more as he's done a lot of digging and research into unlocking and working on that branch of the Lantiq based chips. I seem to recall him mentioning one instance showing of ReTX from the shell prior to the fix but users were still at this point seeing problems with g.inp.
Some of those claims seem pure hype and aimed to confuse
.
I note he's also selling the WMG1312 for £80 which can be
bought brand new for £60
