Re: Poor and intermittent service - fault diagnosis doesn't work

Hey MD2011, 

Thanks for keeping in touch 🙂

There's lots of reasons time-outs could occur, which is why we send tech's to investigate. When is your visit?

Speak soon, 

Take care.

Re: Poor and intermittent service - fault diagnosis doesn't work

Hi Heather

The engineer came yesterday and couldn't get a lock with any of his test gear either from inside my house or from in the pit. So he called Network and they came out later. They said there was need to replace an amp in a damaged cabinet up the road which should have been done before new service roll out in my area, only that hadn't happened. So modems on this circuit have been trying to get locked to channels which have not been present. They said they were going to replace the amp last night and the WAN went down for about an hour as they predicted it would. But looking right now at my router status I see the following:

Downstream bonded channels
Channel    Locked Status    RxMER (dB)    Pre RS Errors    Post RS Errors
1    Locked    38.6    587    2927
2    Locked    38.9    590    2659
3    Locked    38.6    482    2910
4    Locked    38.6    584    2763
5    Locked    38.6    512    4214
6    Locked    38.6    518    4102
7    Locked    38.6    506    4197
8    Locked    38.6    515    4041
9    Locked    38.6    536    4051
10    Locked    38.6    528    4027
11    Locked    38.6    453    4083
12    Locked    38.6    520    4004
13    Locked    37.6    512    4090
14    Locked    38.6    519    3888
15    Locked    38.6    546    3952
16    Locked    38.6    101    310
17    Locked    38.6    143    335
18    Locked    38.6    150    335
19    Locked    38.6    125    6429
20    Locked    38.6    123    5277
21    Locked    38.6    167    316
22    Locked    38.9    164    311
23    Locked    38.9    131    328
24    Locked    38.6    16    287

Upstream bonded channels

1    ATDMA    0    0    0    0
2    ATDMA    0    0    0    0
3    ATDMA    0    0    0    0
4    ATDMA    0    0    0    0

 

So my T3 and T4 errors have not returned but I'm still getting POST errors and sync timing failures from today

 

Also this is still much the same or worse:

Re: Poor and intermittent service - fault diagnosis doesn't work

Hi MD2011,

Thanks for getting in touch. I am sorry to see you have had trouble with your connection.

 

I have taken a look and things seem to be ok from this side. It may help to try the following so we can rule some things out:

 

Pop the hub into Modem Mode with the computer in Safe Mode with Networking at different times of the day.

 

Try on separate devices.

 

Check Ethernet cable. Make sure it is new / up to date. (Cat 5e or above).

 

Make sure device is capable of agreed speed.

 

Check wireless card slide.

 

Take care.
