I've been having some serious disconnection problems the last 1 or 2 weeks, lately its been dropping every 10-60 minutes and I've got another unrelated problem with Flash player that keeps crashing any browser I use when the internet drops which makes the disconnections that much more painful when they get to be every 10 minutes. (I've updated Flash player if someone was thinking of suggesting that)
I was wondering if I could get some help on whether or not my connection rates are normal. I've read done the isolation test.

I'm in the Gate Pa, Tauranga area
I'm on Xnet FS down 256k up
PC running Windows XP Pro
Modem is Linksys AM300 (Updated firmware to latest even though it was already up to date. Also its only about 4-5 months old.)

Are my stats normal? If not what should I be getting? (I've seen various threads with people stating they get anywhere from 3000-16500kbps Downstream rates.)
Downstream Rate:      991 Kbps
Upstream Rate:          165 Kbps
Downstream Margin:   12 db
Upstream Margin:       -24 db
DownLineAttenuation:  61
UpLineAttenuation:     40
DownTransmitPower:   20
UpTransmitPower:       11

Connected straight to another phone jack. (10pm)
Rates

Same as above but 8am
Rates

Speed tests around 10PM 3rd December
Speedtest.net
Xnet.co.nz

Just a couple more questions.
My Upstream Margin flicks from 25ish and -25ish, is this normal?
I have several ADSL cables (To connect the modem to the Jack/filter) one of them is crossover and the other is straightthrough or are these a different kind of cable that don't have such things as crossover etc.?
Is there anything I can do to increase my modems connecting speed? (From power on to Internet ready.) I've manually set DNS servers in hopes of achieving this but it didn't do anything. It can take anywhere from 2-10 minutes to connect.
Will local exchanges show up on Google maps/earth? If not how do I find out how far away I am from the nearest one?

the higher the DownLineAttenuation the further you are away from the exchange, the formula is if you divide the DownLineAttenuation figure by 13.81 you will see how far away you are and you are over 4km so the best you can do would be in the 3000 to 4000 range so 900 is not good. your upstream margin has serious problems if that is a minus 25 it should be higher than download margin in most cases so maybe someone can tell you why but it is probably the reason you keep dropping connections

Is the Downstream Line Attenuation accurate? Because it changes from 60-65. Is that just because of traffic or something?

Usually if I check the status as soon as its connected the Upstream Margin is 25ish but checking it again a minute later it always changes back to -25ish.

have you had broadband for long ie has it always done it, because it sounds like you may need someone to check your phone wiring , but if you can try different filters, phone jacks etc, try that first, but you may have to ring Telecom and explain your problem there may be a charge depending on what they find, but if there is a wiring problem then you will need to fix it to get your broadband to work




Common sense is not as common as you think.

I've had broadband for years. There have been the usual disconnects (I've never encountered reliable New Zealand Internet).
But the constant d/c has been the last 2-3 weeks. I've tried different filters, jacks, cables but they don't change much on my modems status page. I haven't been able to really test the d/c because sometimes it will go for a long time then get bad. For instance this morning I didn't d/c for 3-4 hours but more than likely this afternoon things will be different.

I'm gonna keep the PC connected straight into the main jack all weekend with the phone unplugged and see what happens.

Is the ADSL light dropping out? If so, check out this guide and perform an isolation test.
During the isolation, record how often in drops. Try another router in it's place if you have one spare.

Then, if it's still dropping whilst isolated you'll need to log a fault with your ISP.
