When I first signed up with XNET I could sync at 5-6Mb/s. However, a few months ago the speed dropped overnight to 500-600kb/s.

I've let i sit for a while but i'm finally feed up with slow download speeds.

I've tried a few things to sort this out:
1) had the port reset - no effect
2) removed all other devices from phone jacks- no effect (I should point out that there is another device which I believe is the control for the hot water cylender - which I dont want to touch)
3)rebooted my wag54gp2 a million times - no effect - although this seems to be an untrustworthy device from what i've read on the net.

What are my options?
XNET suggested I get a technition out which could cost me $200 if it turns out to be a problem with my modem - (do they make $200 an hour or is someone potentially making a fat profit off my misfortune? - i think I know the awnser to this one!)

I'll try borrow a modem over the next few days but thus far everyone i ask is using thiers...

I have access to test gear if it helps - scopes, multimeters, sprectrum analyzers etc

Here's what the modem says: (the downstream rate is good today)

DSL Status:       UP
                                    DSL Modulation Mode:             ADSL2
                                    DSL Path Mode:           INTERLEAVED
                                    Downstream Rate:         739 Kbps
                                    Upstream Rate:              240 Kbps
                                    Downstream Margin:     13 db
                                    Upstream Margin:          14 db
                                    Downstream Line Attenuation: 52
                                    Upstream Line Attenuation:        53
                                    Downstream Transmit Power:    0
                                    Upstream Transmit Power:         0

Cheers

Both of your up and down line attenuation is poor. It can be your line, any devices (or cables) still connected to your line, or the modem. Borrow another modem to see if that is the problem. Does the dial tone (or disconnected tone if on Fusion) sound normal/okay?

"All-in-one" modems is a bad idea, as an ADSL modem gets hot and a wireless router gets hot, combine the two and you are asking for trouble. All that heat dries out capacitors and fries the chips. (Ahhh, chips.)

You can never have enough Volvos!

Do as Niel suggested but of course thats only one half of the possible problem the other end is the remote adsl modem/port.

Xnet are great at resolving faults email them or phone and advise you have low upstream and downstream connection speed on your adsl line, and youve had a port reset nothing has worked ask to be changed to a different port in the exchange they will resolve that pretty quickly you should find.

I had the exact same problem about 6 months ago.

Thanks for your input, will pick up another modem tonight and see if it gives me the same sync speed.

Will let you know what happens...

You havnt just had sky installed or anything like that?

We got sky installed and they put in an extra phonejack for the skybox, and the cheap bastard installer didnt install an ADSL filter. If you have sky, see if its plugged into a wall socket, and unplug it. Breaks some stuff like boxoffice I think, but you can always plug it back in if you need it at the time.

I'd try unplugging your mysterious hot water cylinder phonejack as well.. I cant imagine it breaking anything if you unplug it for 30 minutes to test things. If it is the culprit you might just need to get a filter for it.
