BT modem and Homeplugs


[link to this post]
 
Had Plusnet fibre installed yesterday. New PN Technicolor router and standard BT modem. No problems except one. Speeds were fine if connecting to router direct with cable or WiFi. However there was a dramatic loss of download speed (50+ to 3) when connecting via 500AV homeplugs. Spoke to Solwise who supplied the plugs. Very helpful. They suggested changing the power supply unit to the modem as the ones supplied by BT were rubbish and induced a lot of noise on the line. Followed his advice and BINGO, dramatic improvement. Speeds on Homeplug now 40+. Hope this might be of some help to others and that BT might take note.

Wow

I'd love to know if the PSU ends up inducing faults on the DSL connection too!

Which modem do you have and what power supply did you get?

The modem is from Open reach, a Huawei EchoLife hg612. The PSU supplied by BT was Chinese 12v 0.7amp. Replaced with an old PSU which I had.

Was the PSU white or black?

Certainly possible.
Recently diagnosed a drop in sync speed and refusal to connect at ADSL 2+ only at ADSL2 to a dodgy psu on my network switch adjacent to the modem/router.
Only diagnosed it by elimination and the psu then failed on powering up again.
Only took me a week - blamed the exchange at first !

I would think it's black, the newer white ones are 1 amp I believe.

I have three power supplies plugged in just under my modem, I wonder if they are making any difference.

I think the same. I wonder what version the modem is?

My broadband basic info/help site - www.robertos.me.uk | Domains,site and mail hosting - Tsohost.
Connection - Plusnet UnLim Fibre (FTTC). Sync ~ 58.7/14.6Mbps @ 600m. - BQM

What are the transmit/receive speed shown on the devices page of the HomePlug AV Utility software just to rule out issues with the plugs connecting across ring mains.

I assume the homeplugs are plugged directly into the wall sockets and not a multiway extension especially if it has surge protection.

I use a couple of these

for modem and router no problem at all apart from having to replace the output plugs.
