Re: [OUTAGES] 11/13/2012 12H30

still no go as of 12:30pm today (downtown Ottawa – St.Laurent POI) ... I just put the modem back at my parent's in law place. I did reset which didn't help. it seems 8db Attenuator installed by Rogers tech it is doing its job, as I was able to get better power up readings.
They are using 5120 modem on 18mb service.

WITH 8db Attenuator
the signal to noise ration is 34db
down stream power is +6dBmv
up stream power is +45dBmv

WITHOUT 8db Attenuator
the signal to noise ration is 34db
down stream power is +13dBmv
up stream power is +37dBmv (moving target 0 to 13 to 23 to 37)

Since the modem is trying to sync up and it is looping the up stream power is moving target.

I looked into modem logs and there are always 3 messages:

1) critical
SYNC Timing synchronization failure - failed to receive MAC SYNC frame with

2) warning
DHCP Warning - Non Critical field invalid in response

3) critical
No Ranging Response received T3 time-out

It is not provisioning issues, because their modem works at my home (Fallowfield POI) vs theirs St.Laurent POI.

Since the signal looks ok, is this DHCP issue ? Its been over 7 days without internet…. What is going on????
Can Rogers try to fix this remotely from their end, do you think sending another Rogers technician will help????

Hello,

Yes, there is definitely an improvement in the signal there. The SNR could be a bit higher, but it is still within spec. Can you confirm (on your thread in the direct forum) the IP address they are receiving when connected directly to the modem?

I wish you guys asked me for the info before I returned back from their place. I will get you the info around 6pm when everyone is back from work. I believe TSI tech asked me this yesterday when perfomring ipconfig. Maybe it is in the notes. I could be wrong, but from what I remember it was 192.168.101.1.

Hello again,

In the direct forum post you mentioned that with the splitter Rogers installed they had:
up stream power is 0db

And without it they had:
down stream power is 13dBmv

Notes on account do not show IP information but they do show:
After Splitter:
US 0
and on the next call:
Modem Tx Power: 33

Both calls also showed 13 for downstream without splitter.

The numbers that you posted here do look good, but all the information we had prior to your posts this afternoon show an issue still present with the signal with or without the splitter Rogers installed.

I asked about the IP information now because the signal levels you posted this afternoon are within spec and you inquired about DHCP. All previous info provided looked like the issue was signal related. The IP that you notated is provided by the modem (would be 192.168.100.x) which would be expected if the signal was not good and the modem was thus offline.

On a side note, this time it is okay because again it appears to be a modem IP and not your actual IP address, but in the future please only post IP info in the direct forum as this could be sensitive information the public should not have access to.

Do you recall if you had to manually set the IP address on the computer in order to access the modem and obtain those signal levels? If the computer was programmed with an IP for the modem and this was not switched back to obtain IP automatically that would also leave them unable to connect.

Thank you,
Keith

Keith,

Like I said in my posting in direct forum, the up power signal is a moving signal. It is not static becuase modem on its own is cycling trhough send/receive etc to sync/connect the modem. Therefore giving you an exact values for up power levels is very tricky. Yes I did talk about splitter that how my inlaws desribed the device Rogers technician installed. It is actually attenuator to weaken the signal.

I knew the IP I posted was modem related thus it was safe to post on public forum. I will get you info you are looking for once I get home. Will ipconfig be enough? THe power levels didn't change since I called you on Monday, so if TSI CR wrote the IP it should be the same.

I didn't have to set any IPs manually. I just typed 192.168.100.1 in the browser to access their modem.

There were no changes to their hardware configuration. Last week on Monday evening they had working interent, the next morning it didn't work and it still doesn't work. Also they've used yoru service for almost a year (I'm guessing) without need for any attenuators...

I just don't get how the service can work one day and it stopped working. The only thing that comes to my head is Rogers did something on their POI...

Thanks,
Martin
