Hi all

 

I have VDSL with a Dlink 2888a modem.  We have had VDSL for about 6 months.

 

Download speed on the modem says about 54000, uploads around 16000

 

Speed test over wifi on various devices ranges from 30 to 38Mbps, and similar via ethernet. I have a master filter installed.

 

I had to reset my modem at one point recently, and just trying to set it up how I had it

 

The VDSL profile settings by default are all on, last night I switched them all off except for 17a. Is this going to cause a problem? I had been having issue with a particular HD iptv stream (used to work well but lately some buffering, it works well with similar speed mobile data, so I think my current speed is just on the brink of being too slow, so trying to fine tune), but seemed to work better just having 17a turned on and nothing else.

 

Bitswap and SRA are left turned on.

 

All the other switches like ADSL and annex m and annex whatever defaulted to on, but I have switched them off and just left VDSL turned on.

 

Should I leave 17a turned on only and see how it goes - or does that mean if there is a problem it will cut out and cant fall back onto 8b or whatever the other profiles are? Should I leave all the profiles turned on, or only a couple?

 

Thanks

Ideally you should leave both on, sometimes the dslams do get their panties in a twist if you try to force a profile.

 

 

 

The Fritzboxes normally prefer to perswade the dslam to go 17a. If it's a Vectored area you will only have 17a offered from the DSLAM anyway.

 

There is no real benefit to disabling modes.

 

 

 

 

 

Your speeds are likely due to testing over 2.4Ghz wifi.

Thanks for that, testing is mainly over 5ghz wifi on my phone, or via ethernet to my nvidia shield tv.

 

I will turn 8b back on? Is that the only other one I need to worry about?

 

What about annex a and annex m?

 

Cheers mate

annex a & m are for ADSL. not relevant for VDSL.

 

 

 

chorus don't allow VDSL lines to sync on ADSL so there aren't any concerns there.

 

again, I'm not sure why your messing with this?

Great thanks for clarifying, just wanted to have it set up how I did previously before a reset, as I didnt feel it was working as well as before.

 

Obviously sounds like I needn't had bothered.

 

Thanks

Myself included...

 

Tend to learn overtime though..... it's a fast way to hard brick a dslam port, requiring a man in a van to come and reset the card...
