my dad has been having LOTS of problems with disconnections

sometimes every 15 mins - wrecking his online gaming ! been like it for about 2 months, has had Plusnet on the case, BT even came round and found nothing much wrong, although they re-did the terminals on the main box, which improved SNR a bit. and his download speeds have gone up.

he has a Speedtouch 510 and the free box that came with Plusnet (Voyager 105)

can anyone recommend a decent router that is good for a poor line please ?

what I don't understand that even though is SNR is pretty bad - the line always negotiates at 3MB minimum 4 mb most times, and 5.5 MB somtimes !! I asked my dad to ask Plusnet if they could fix it at 2MB for a more stable line but they said that they could not.

any recommendations please ?

here are some of his stats before BT came round -they are slightly but not much better now

many many thanks, Mark.
 
ypu can ask plus net to downgrade the service to 2mb fixed that would solve a lot of problems also on the router side a netgear dg834g or GT or a speedtouch 585v6.
 
Failing that, PN should be able to get the target SNR margin increased - are you sure the connection's actually losing sync?
 
yup it shows its loosing sync on the logs

PN are being useless to be honest - they just keep sending my dad very technical BT reports, I'm an electronic engineer, and a PC nut and even I don't understand their emials !

here are some SN figures registered my my dads router (before BT visit but not much different)

my dad did ask on my request ot get them to lower the line rate - ie 2mb fixed but they said they couldn't !

are these SN figures good or bad ? I've always been on cable so ADSL is new to me !

many thanks for all of the posts :) much appreciated

Output Power (dBm) up/down = 12.0 / 19.0

Attenuation (dB) up/down = 29.5 / 48.0

Noise Margin (dB) up/down = 22.0 / 6.0

Output Power (dBm) up/down = 12.0 / 19.0

Attenuation (dB) up/down = 29.5 / 48.0

Noise Margin (dB) up/down = 22.0 / 8.0
 
They're high - the default target SNR margin is 6dB, so anything above that is room to breath. If the connection's unstable the Digital Line Management that BTw run will increase the target SNR margin.

It's normal for the SNR margin to fluctuate, but something would have to be wrong for it to fluctuate by 16dB.
