strangely slow

[northernmonkeyjones]

I have been using a 7800n for quite a few years now with success on a very long BT line and without many issues first on Virgin and now on BT standard ADSL.

I have had a few line faults etc but a couple of weeks ago the 7800n started to crawl along at under 1Mbps, and I was struggling with wifi range. Anyway I bought myself a shiny new 7800DXL which i though might cure the problem. But no. So I contacted BT to see if there was a fault, first call said they couldn't find one, the next a couple of days later said they could find one and that it would be cleared, and that the connection was performing as it should.

The wifi seems to have improved but my connection is still slow as ever. However when I plug my pretty much unused BT hub3 in the speed improves dramatically. to around 2.7Mbps.

Are there any settings I should be changing out of the box to make this better? I have fiddled with the SNR on my line for many years now, and had settled on the fact that around 5-6 seemed ideal any lower and it kept dropping, and indeed that is what the HH3 was hitting and what it is on auto, even if i leave the SNR on auto (about 6) it is still much slower than the HH3, which isn't right.....

I have it set on

PPoA 0/38
VC/MUX
1500 MTU
with Firewall and NAT enabled.

I only have G.dmt enabled, and SRA checked (just to see if it made any difference, which it doesnt)

am also running the latest Firmware i can find.

don't think I am doing anything wrong in terms of settings any maybe it will get faster if I leave it on for a few days. If I doesn't I will have to ask BT to retrain the line.

OK, might have got to the bottom of this.

It seems to be an issue with one of the devices in the house taking up all of the speed, its not that the HH3 was faster it was that it had a different SSID so the thing which was slowing the network down and eating all of the bandwidth wasn't connected because it didn't have the config info for the HH3.

Have changed the SSID on the 7800 now and there is only the mac book connected on 5g wifi. No restarts of the broadband and normal service of about 2.7mbps resumed.

Just have to figure out what was slowing down the system. probably by connecting one device at a time.

its the iMac.

caused by iPhoto photo stream.

Now disabled and all back to normal.
