Hi guys,

Just spoke with the Xnet Technical Helpdesk regarding some issues and they pointed me to this forum, so here goes:

I'm having some issues with call clarity on the VFX service, and intermittent connectivity issues to the Fusion Naked DSL service.

I'm using a Linksys SPA2102, with a D-Link DSL-2730B.
My primary computers are a Apple MacBook Pro and an HP DV6-1103AX Notebook with Windows 7 Pro.
If it's important, my computers connect via Wireless N to the D-Link router.

I've enabled QoS in the DSL-2730B, at present the default DCSP marking is set to (-2) Auto Marking.
I can set up QoS Classification rules but I'm unsure of which DCSP Mark the VFX traffic gets from the SPA2102?

Regarding the Fusion connectivity issues, the helpdesk is doing a 24 hour analyzer, but I'll post this anyway, in case someone has seen it before.
Sometimes the WAN connection goes offline with no warning, usually preluded with about 30 seconds of no response from WxC DNS servers. Often the wireless connectivity stops working too, with my laptop returning a connection timeout error.

I hope someone can shed some light on these issues.

N.B. If a WxC specialist needs my username or account number please PM me.

Many thanks in advance,

Matthew McTague

Saves them sorting it out I guess.

Have you upgraded to the latest firmware on the D-Link DSL-2730B? We've found these to be a bit flaky on earlier firmware versions.

Yes I've upgraded it to the latest firmware, AU_1.01.

Call quality comes with the territory. Maybe 1 in 10 times I try to use the phone (I use it maybe 2-3 times a week) the quality is crap, I assume from high network usage and so I just use my mobile. It's cheap and I can't be bothered calling up world exchange to complain, if you need a land line get a proper telecom connection. I am totally satisfied with the service however, internet works fine and the voip works most of the time flawlessly. For $80 a month I couldn't be happier.

I'd suggest you troubleshoot in two stages.

First thing is to sort out any network/ADSL connectivity issues - if the underlying network is flakey, then VOIP (or anything else for that matter) is never going to work correctly. Then, once that is sorted, if VFX is still not going, then troubleshoot that.

What happens when things go wrong? Is the modem still showing an ADSL link, or has it dropped the connection? Is there any pattern to it - certain times of day, or when you do something in particular on the computer?

If possible, I'd suggest trying a different modem temporarily to see if that helps connection stability.

Yep I see what you mean. It varies, with no particular pattern. Often the ADSL indication light is on, but there is no internet access.
Unfortunately I don't have an alternate modem to try.

When it stops working, have you tried doing a traceroute back to www.xnet.co.nz or similar to see where things fall over?

Also, try posting your modem DSL connection stats here to see if there is a connection quality issue.

Good idea, I'll do a traceroute next time it happens.

No response during the issue, but when the connection came back:

I've made a change to your voice service to use a higher quality voice codec, can you please give your SPA2102 a reboot and let me know with some call examples via PM of any poor quality calls you are still experiencing.

We are currently just waiting on our 24 analyser to complete to get an idea of what the DSL line is doing in regards to your disconnection issue.

Karl,

I just spoke to Lee at your helpdesk, he said that the 24 hour analyser came out fine, so I'll just wait until it happens again to troubleshoot further.

The better voice codec works great thanks, the call clarity is much better :)

Thanks!

If the 24 hour analyser came back fine, yet you had an issue yesterday afternoon, then there may well be a wiring or hardware issue in your premesis.

Have you done an isolation test etc. to rule out any cabling issues?

Also, are you using the SPA2102 as a router, or just as an ATA?

Ok, it's possible that it's an issue on the premises, but I doubt it. There's a good chance that it was an actual fault.

I'm using the SPA2102 as an ATA, I could change this if you recommend it?
Would the wireless from the DSL-2730B bridge happily if I did that?

No I haven't done an isolation test. i only have one other phone socket in the house, so should I try that?
The problem occurs inconsistently and sporadically, and the router always works fine when I restart it, so should I try the other location for 24 hours?

Thanks for your continued assistance :)

If you have Sky, unplug it from the phone socket as part of an isolation test. It periodically phones "home".

You can never have enough Volvos!

If the analyzer came out fine, this means that there were no dsl resyncs, meaning that it could be that the modem keeps the sync up but loses ppp. This usually means a problematic modem, i'd suggest trying a different modem if possible.
