Traverse Viking ADSL-2+ Card Problem
-
I lowered my DSL download speed this morning at ca. 9:08 am from ca. 15 Mbs to ca. 10 Mb/s to see if it would reduce my packet loss, however, the speed change had the opposite effect–it significantly increased my packet loss (by over an average factor of two)! I wonder what could cause this increase when the speed change served to increase my S/N by ca. 6 dB? Perhaps the source of my packet loss is not my telephone line after all?
-
It could be an issue with apinger itself. Quite a few people have reported that though mostly with ridiculous figures like >100% packet loss!
Do you see packet loss if you just run a ping test?Steve
-
I'm still collecting data, then I'll try the ping test. Here is a graph of when I lowered my download speed to ca. 5 mb/s, attaining a ca. 21.5 dB S/N. Note the continued increase in packet loss as I lower the speed and thereby raise the S/N.

Steve:
Doing repeated simple pings to my DSLAM (IP address changed below to disguised it) I get no packet loss:
PING 12.9.74.1 (12.9.74.1): 56 data bytes
64 bytes from 12.9.74.1: icmp_seq=0 ttl=127 time=16.261 ms
64 bytes from 12.9.74.1: icmp_seq=1 ttl=127 time=16.658 ms
64 bytes from 12.9.74.1: icmp_seq=2 ttl=127 time=16.686 ms–- 12.9.74.1 ping statistics ---
3 packets transmitted, 3 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 16.261/16.535/16.686/0.194 ms -
Back to ca. 15 Mb/s with increased power and S/N, both downstream and upstream; this can't be right–it's got to be an apinger problem. Yup, restarting apinger tames its readout:
-
Try setting apinger to use a different remote address. Preferably something close to you.

I tried a different IP address in apinger and basically got the same packet loss results. On the other hand, I tried running the ping tests at dslreports.com and saw no packet loss. Also, all ISP tests on my DSL line indicate it is stable. I am trying another, off site, ping test to my IP address and will report back on it when I obtain the data.
-
A 24-hour Ping Test (via dslreports.com) shows zero packet loss in tabulated data and graph (notch down in graph shows transition from Interleaved mode to Fastpath mode):

I'll go home and check, I'm not sure if you'd be interested trying a different PCI ADSL modem as I have a case of ones that I use to sell and get a pretty penny for on eBay. I actually just fig them out planning on selling them again for some extra dough. I'll post the model and if your interested cover shipping and one is yours.
-
The card I've got is a Songoma S518 ADSL Card 2005 Rev. C (low profile model with full size bracket), about 3 years ago I was getting over $100 each for them. Your welcome to one if you want to try a different adapter, just cover S&H.
-
The Sangoma S518 is a real modem, rather than a router/modem on a PCI card. As such it requires a specific driver and I'm not sure one exists for FreeBSD. There is a Linux driver though so it may have been ported.
Edit: Not listed on the main support site but there is a FreeBSD driver: ftp://ftp.sangoma.com/FreeBSD/wanpipe/
Not sure if anything newer than FreeBSD 6 exists though.Steve

I would not mind having one of the Songoma cards, but it would be of no use to me unless there is a current driver for it that will work with pfSense–and the specs I found for it seem to indicate it does not do ADSL2+ as it has a download bandwidth limitation of 8 Mb/s. I also have explored purchasing a commercial-grade modem, however, they are very expensive--my LinITX card seems to be sailing pretty smoothly now.
-
My pfSense router has run for 23 days now without a reboot or PPPoE disconnect–I was hoping to report on it here after a month without a reboot, however, my local power utility experienced a brownout this morning that forced a reboot--but I guess I'll call my new ADSL2+ modem card a success at this point anyway. Thanks, jonesr, for your card recommendation!
-
Not a problem, I am glad you are happy with it.
If anyone else has been following this thread I still have one of these cards and would be happy to send it to anyone in return for a donation to the pfSense project.
Completely off topic, but I met someone recently who I told me he had met two people writing 802.11n drivers for FreeBSD, and told them they were wasting their time and to do something worthwhile with their lives. He and I share the same first name, you have just reminded me to make a donation to the FreeBSD project in our name.

Sounds like a useful individual. ::)
