I recently changed over the xnet fusion and purchased a Linksys AG300 modem/router due to my old modem not supporting the SIP protocol for VOIP.
It has been a headache since day 1, with my connection dropping out every hour or 2, the modem has even locked up and I couldn't ping it a couple of times.

At one stage when the connection dropped out, I noticed on the status page that the downstream margin went up to 2147483643 db, normally about 12-13db.

So after a couple of days I swapped modems with a friend to test. I'm now using a Dlink DSL-504g with no problems.
He has been using mine and its been OK for him except he had it lock up once in the 2 days he had it, no connection problems or anything tho.

Is the AG300 is incompatable with my exchange (if that is possible), or does it just sound like its faulty?

Any ideas?

The linksys routers are notorious for having bad modems (low sync speeds, unable to hold a ADSL sync) We had played with most of the routers on the market and found the Netgear DG834G to be the best, no lockups, very good throughput and modem with a very easy to use interface and they arn't expensive either.

The D-Link routers Xtra have been shipping for 2 years which are ADSL2 compatible arn't actually able to sustain more than 7.6MBits throughput, some can be firmware upgraded which allows better throughput. They still sync at ADSL2 speeds. Telecom Wholesale have a document describing these faults with their own routers they have been shipping...ooops.

Also they have a habit of bricking when doing a firmware upgrade. Joy :)

Wish I had off known not to buy linksys a week ago.
It still doesn't explain why it works 20 times better for my friend than it does for me.
The netgear router you talk about, is the non wireless version go just as good. I already have a Belkin N wireless for that.

Modems perform differently for different line conditions, that explains why it works a lot better for your friend. I believe the D-Link is more stable on long/marginal lines, but that is just something I've heared. Linksys might be better with short, good lines. Apparently the Dynalink works well for all conditions, if you find one that is assembled properly.

I have an Linksys AM300 and I have had absolutely no problems with it at all. Its uptime has been 35 days and counting, its has never dropped out, and is currently synced at:

Downstream Rate:	11817 Kbps
Upstream Rate:	944 Kbps

Which to me seems very good.

Update

Just tried an Allied Telesyn AT-AR256E modem, which is also experiencing connection problems.
So far 2 out of 3 modems can't hold a connection.
Do i have a bad quality dsl line, or something else?

Update:

After Xnet having logged the fault with Telecom my connection is a little more stable, they must have reduced the speed or something cause my modem only connects at 5600Kbps now.

To try help sort out this problem I've replaced the old telephone wiring in the house with cat5, and removed the security alarm that used to be wired in. Have only got the 1 telephone jack connected to this line at the moment, all others have been disconnected.

I can keep a connection for about 24hours now, seems to drop off once per day, usually at night.

I plan to rewire the phone jack that i'm plugged into and move it to the other side of the room, so I can remove my 10m extension cable, I hope this helps. After that I don't know what else to try, anyone have any other fixes.

All I can say is I will never buy another Linksys modem
