Hi,

Slow broadband connection and having little joy with the xtra help desk, so hoping someone here might be able to help me isolate what the problem is.
Pretty new to networking stuff so please bear with me; spent an hour or so reading this morning and wondered whether the following might be of use:

Using a combined modem/router D-Link DSL 502T.
Interestingly, run Ubuntu linus on a second partition and connections there are faster, although still much slower than usual.
Have tried with IE7 and FF3 so don't think it's a browser issue.

Cheers,

Blair

A friend is having a simular problem. Have you recently accept telecm promo offer to upgrade your 3 gig go plan to 6 gig at ne extra cost. Because once they did all these slow downs and drop outs started happening

Thanks for the reply,

Spoke to my parents (their computer) and they're pretty sure they didn't.

The Xtra help desk/technicians have been of little use so far; they "escalated" the problem five days ago after it was found we were being disconnected every 4-15 minutes.
A technician called a couple of days later, said everything looked fine at that moment, and wanted to close the case!!!
He grudgingly agreed to keep it open, and we're meant to get a call today.
Was hoping I could provide him with some stats that might point him in the right direction - would these be useful?

Is the router's firmware up to date??

blairm

Hi,

Router firmware is v3.00B1T01.TX20070418. It's what came loaded on the router when my parents got broadband in February.

Cheers,

Blair

Thanks Speedy... but what does that mean?
Networking is not an area I'm familiar with at all. Haven't even got round to connecting all my computers at home!

Cheers,

Blair

Updating the firmware may fix it, if its a revision C modem (look on the bottom, whats it say alongside H/W ver)? Ax or Cx?

Like here (http://files.dlink.com.au/products/_images/REV_A.jpg)

Or here (http://files.dlink.com.au/products/_images/REV_C.jpg)

And does it say Generation II on the front?? bottom right? like here (http://files.dlink.com.au/products/_images/DSL_Gen_II.jpg)

So what exactly is the problem.
Are you getting some websites and not others or is your modem disconnecting at times.
Are you getting a steady DSL light on the modem at all times.
When you have a problem have you lost the PPP light indicating it has disconnected from Xtra.
If PPP light goes out does it connect again and come on again by itself.

The issue is very long delays (in some cases still waiting after 5 minutes - I have timed that with a stopwatch) getting some pages and time out screens apprearing in the browser on other pages.
The sites I'm seeking where there are delays of up to 5min have in the past couple of days included the TAB, Slashdot and Stuff.
Oddly enough, I can go back to those sites a few minutes later and it's much quicker.
Would say the problem is experienced with about 40% of searches/page requests.
Generally things are fine for a few minutes after restarting the computer but then we strike problems again.
Re the loss of the PPP light - is that the ethernet light? If so, it stays on. ADSL is mostly steady, with some blinking at times. Status is blinking pretty much all the time and power is always on.

To Speedy - it's a revision C Generation II model.

Thanks,

Blair

I would go here (http://www.dlink.co.nz/tech/)

Select DSL then 502T

Downloads / NZ, click on rev C firmware on the right

Download the update, update it then reboot the router

See if its any better. Turn of any antivirus / firewall programs while you do it

Try changing the MTU setting in the modem configuration to 1492
I have seen this sort of thing often with D-Link modems with MTU set to 1500.

Keep in mind if you do a firmware update you have to do a factory reset prior to and after the update so make sure you know all the correct settings to put back in.
The instructions are on the web link speedy gave you under Upgrade Firmware
Personally I would only do that as an absolute last resort as this sort of procedure can easily go wrong.

Many thanks for all your help so far,

Just had someone drop in so won't have a chance to try these suggestions for a couple of hours.

Will keep you posted.

If you have sky TV decoder with phone connection, make sure a ADSL line filter is used as Sky can interfere with Broadband.
