| Good modem/router combination?
I just switched from Verizon's 3.1 package to their 7.1 package. My line was switched over from ADSL to ADSL2+ and, I received a Westell 6100G modem/router to replace my Versalink 7500.
I was told the 7500 may not be able to handle the full capacity of the new line configuration. The 7500 syncs at 7645 downstream while the 6100G syncs at 7669. Upstream holds steady at 863 on either box. The margins, attenuation and transmit power do not change much between the two.
I have several wireless and one wired computer that need networking so, my current configuration is the 6100G in bridge mode (providing the DSL) and the 7500 does the PPoE and routing.
First question:
Is my setup correct?
At Present, the 6100G has the DSL line so, the DSL light is the only one lit. The 6100G is connected to the 7500 via the VersaPort (WAN uplink mode). The VersaPort is set to PPoE mode so, the internet light on the 7500 is lit. The 7500 does all the routing as usual. Transceiver stats for the 6100G are not accessible.
Initially, I changed the 7500's IP so as not to conflict with the 6100G, hooked the 6100G to the 7500 via the VersaPort and tried everything out. All was well until I did a connection test on my Xbox 360 and found my NAT to be moderate. The 6100G assigned an IP to the 7500 and, the 7500 served the various devices connected to it. Transceiver stats for the 6100G were accessible.
Second Question:
Is the 7500 a sufficient router in conjunction with the 6100G?
The 6100G is equipped to handle ADSL2+, the 7500, ADSL (I assume). is the 6100G's output degraded as its routed through the 7500? Should I invest in an ADSL2+ compliant router.
Thank You for your time and please forgive me for being long winded.

It's set up right and should work fine.
But you shouldn't have to do that. It's hard to believe that the 7500 isn't compatible.
It would be very interesting to see the transceiver statistics from that 7500, the 6100 too for that matter. Those stats will show whether it is using the ADSL2+ or not.
edit No, the ADSL2+ part of the signal stops at the 6100, no degradation, it's ethernet from there. Sure, if the 7500 does everything you need it's plenty router.

Data Path FAST
Transceiver Information Down Stream Path Up Stream Path
DSL Speed (Kbits/Sec) 7645 863
Margin (dB) 9.9 13.1
Line Attenuation (dB) 41.0 24.1
Transmit Power (dBm) 13.9 12.4
Westell 6100G:
Transceiver Revision 3.3.2.2.0.1
Vendor ID Code 4D54
Line Mode ADSL_2plus
Data Path FAST
Transceiver Information Down Stream Path Up Stream Path
DSL Speed (Kbits/Sec) 7669 863

The line was switched this friday past (10/9/09) and the 6100G was delivered on the same day. The ready date was scheduled for 10/13 and my connection just dropped a few minutes ago before I could post this!!

1 edit | The downstream margin's a little low, but it's definitely utilizing the ADSL2+, and Fast Packet mode. If the stats are similar with the 6100, there's no reason I can see to use it.
Looks like the line may be a little long to get and keep full sync speeds, but if it's stable for you it should stay close.

| I'm supposedly 7471 feet away from the CO. Here is roughly what my stats looked like when I was on the 3.1 package:
Versalink 7500 stats (3.1 tier):
Transceiver Information Down Stream Path Up Stream Path
DSL Speed (Kbits/Sec) 3360 800
Margin (dB) 17.9 10.0
Line Attenuation (dB) 38.0 27.0
Transmit Power (dBm) 10.2 11.9 |

| You would expect attenuations of around 8 to ten points lower at 7400 feet, although it is just a rough estimate, still it's a significant difference. It might be a good idea to keep an eye on the stats for a little while, see if any line trouble shows up. If there's a landline, is it noisy at all?

Funny you should mention the noise on the line issue because now I do hear a really slight hiss in the phone. Also, I have a splitter in the jack with the DSL line. The other side has a filtered printer/fax machine in it (fax to filter, filter to splitter).
Sidenote...do verizon ip's normally range from 74.xxx.xxx.xxx to 96.xxx.xxx.xxx because I've synced up a few times now and my ip's interchange from 74 to 96. |

| Yup the IP's dynamic and those are some of verizon's numbers. I would try it without the fax and splitter, see what that's like. If it's no better check any other filters on that number. If the noise doesn't go away, test at your NID if you can, or possibly call the telephone maintenance people to take a look at the line for static/hissing. There does seem to be something, noise needs to be looked after first.

Re: Good modem/router combination?
said by GreyWhyte  :Funny you should mention the noise on the line issue because now I do hear a really slight hiss in the phone. May want to temporally connect modem/router directly to phone company NID test jack. That disconnects inside wiring/equipment. If stats improve may want to think about using a whole house POTS/DSL splitter rather then inline filters. Splitter does a better job isolating DSL from voice.
You can also try disconnecting non-DSL devices one at a time to see if that has any effect on noise. If so try using two filters on the offending device.
As Bytebender posted either modem/router should work fine. There may be slight difference in thruput. Try running speed tests to same sight with each device. Keep in mind difference can also be caused by differences in transient traffic.

1 edit | Well...my connection is stable and the noise is not as bad as it was in the beginning so, I'm content right now...
One of my fax machines appears to cause some sort of line change. The downstream margin would jump from 13.9 to 14.7 when it was disconnected. Otherwise, all other devices are filtered and working well. I think I'm still gonna call VZ to investigate the line for noise.

| Definitely have the noise investigated, less noise=better DSL.
You could try using 2 filters in line on that troublesome fax - sometimes that's needed.
Or, you may want to consider having them install a "whole house filter" or "POTS/DSL splitter" . That's a large filter that goes in or near the NID, that splits one line off for the DSL then filters everything else going into the house, eliminating the need for filters inside. If you have many POTS devices (more than 4 or 5), or noisy inside wiring, such a filter can help a lot.

| I'm guessing the "POTS/DSL splitter" option is out in an apartment situation? The NID is not here in the apartment.
I have put on the 2 filters for the fax like you said. It helps the downstream margin quite a bit.
Here are my current Trans Stats
Transceiver Statistics
Transceiver Revision 3.3.2.2.0.1
Vendor ID Code 4D54
Line Mode ADSL_2plus
Data Path FAST
Transceiver Information Down Stream Path Up Stream Path
DSL Speed (Kbits/Sec) 7669 863
Margin (dB) 11.3 14.4
Line Attenuation (dB) 40.6 22.9
Transmit Power (dBm) 16.5 11.9
My downstream margin tends to creep up through the evening. The highest I've seen it at is 14.7 at about 4 in the morning. Looking back at my stats for the 3.1 line, everything is almost the same. My upstream is better with a nearly full sync, improved margin and attenuation. The downstream has crept up 2 dB in attenuation and loss 4 or so dB on the margin.
Two more questions....
1. My setup right now is the Westell 6100G has the DSL connection and supplies internet access to the Versalink 7500. I'd use the Versalink only but it shaves my downstream speed (7645 vs. 7669 on the 6100G). What is/are the reason(s) for this loss in speed on the Versalink?
2. My fastpath pings, when I had the 3.1 package, were between 15-17ms. Now, they are 30-35ms. Is this normal? Should I be concerned? Double the speed, double the ping?
Thank You again for your responses...

1 edit | I can answer #2 for you. Lately I've been noticing that a bunch of people here have been posting up saying they're on FastPath but are instead pulling 35ms latency. Turns out there might be a bug in the most recent Verizon firmware that is causing the line mode to be mis-reported. You might need to ask Verizon Direct about what mode your line is on (Interleaved or FastPath) to see what they see it as. Someone also suggested an issue going on with ADSL2+ and FastPath. Your line needs ADSL2+ on it though to keep the 7.1Mbps sync. But none the less see what Verizon Direct says about the line.
