Will the wrong router on the line cause issues?

Wasn't sure how to word the title, so please bear with me.

Changed over to VF from BT yesterday. I knew the change was coming and really should have disconnected the old router as I would be out most of the day. However, my Wife was going to be at home and needed the internet and wasn't confident enough to swap routers when the old isp stopped provision. As it happens, the line was swapped out about 7am, so all day the BT router was trying to connect to the VF network. Would that have caused issues once finally connected at 5pm? Would the DLM have seen it as multiple failed connection attempts? I ask as my sync is 12mbs lower on VF than it was with BT, even though on the Superfast 2 package. When with SSE, I managed a whopping 63mbs, which dropped (increased) to 55mbs on Infinity 1, so 43 is a teeny bit lower.

Thanks

I would not expect leaving the BT router connected to have caused a problem. I would expect it to have established a DSL connection but not be able to log into the Vodafone network because it would not have the correct PPPoE userid and password.

The Vodafone router does not establish a good DSL connection. One solution is to connect its covered up ethernet WAN port to an HG612 modem.

That makes sense, thank you. I have a 612 kicking around somewhere, i'll have to see if I can find it to try.

Cheers

The HG612 needs 802.1p set to 2 and 802.1q set to 101
The one I bought on ebay came like that.

Mine came direct from Openreach when I first got fibre. Does it need to be a hacked one or can I change those settings anyway?

I would it first. Loading different firmware is not difficult if you follow the instructions on the Kitz website.

PS See which might interest you! I think it is a Zyxel product.

No need for any setting changes the Openreach bridge modems will just work.

On Vodafone I run a TP Link W9970 as a broadcom based VDSL2 bridge modem connected to Ethernet WAN port of the Vodafone router. The Vodafone router is happy detecting the PPPoE and connecting, and to confuse some it makes the nice claim I am connected over FTTP when doing this.

The vodafone router would drop connection randomly one a night when streaming, whereas with the bridge setup it is nice and stable

With your sync rate that low on the line if suggests an issue - maybe the VF router is dodgy. Having different ISP equipment plugged in won't cause any issues on the day of switch over.

When I changed from Sky to VF I was disconnected in the morning from Sky, but not reconnected to VF until the evening.

You can claim a part refund via the vodafone app on your phone (but only if you are using the VF modem)...

So I am a few days into my experience, I have disconnected a few times (only once a day) and the sync has risen to around 46Mbps, highest was 46.9, lowest 46.1. Upload has increased to 14Mbps. Still not getting anywhere near the 55Mbps guarantee for the product though.

I'm not clear on how to decipher the stats, but the VF router is reporting the following:

DSL Mode VDSL G.993.5 (VDSL)
Link type Interleaved path
Downstream Upstream
Actual data rate 46120 (Kbps.) 14893 (Kbps.)

Error counter
Indicator name Downstream Upstream
FEC Corrections 197 8474
CRC Error 3 0

This is what the BT exchange checker tells me:

VDSL Range A (Clean) 65.4 45.9 15.2 10 39.8
VDSL Range B (Impacted) 52.9 32.4 13.1 6.9 25

I can't find the power supply to my OR modem and I don't have another to put on the line, but I am not sure the VF app would work with it. I need to leave it another 5 days before I can claim for under sync. I have also noticed a slowdown to under 1/2 sync on speedtests this weekend, both multi and single thread. Ho hum, this could be SSE over again
