SH3 Internet Issues and Power Levels

Hi.

Currently looking for some advice, I have been having frequent drop outs for the past few weeks (started just before Christmas maybe). The SH3 will just seem to randomly lose internet access, then usually the WIFI light will come on solid green and the Internet light will be flashing green.

While this is happening I will lose external access, and also intermittently lose local access to the SH3 (runing internal and external ping to monitor the connection).

If I am able to login to the hub while this is happening, I can see on the Home page it reports either:

Internet: Access Denied

or

Internet: Partial Service(US Only)

Once this happens I find that sometimes a reboot of the hub will resolve it (but sometimes not).

 

The SH3 network logs show: the following when the issues are ocuring:

The connection has come back online again today since these logs were generated, but I have noticed the DS Power levels might be a little high over 10 (Power dBmV):

Could this be part of the reason I am having issues?

I have spoke with Virgin support this week, was told they would be sending me a new router today, however this hasnt arrived and now they tell me it should arrive by Tuesday next week, but I am not sure if this will make much difference.

Can anyone advise?

 

Kind regards

Matt

Re: SH3 Internet Issues and Power Levels

downstream power levels are too high  +10 is the max - thats not going to help - you need a tech to sort that

worth posting the upstream levels 

as to a new hub - thats not going to help - you have just got fault finding fix number one - send out a new hub!

Re: SH3 Internet Issues and Power Levels

Hi Tony.

Thats was my thought but glad you confirmed that too.

Here are the Upstream Details for good measure:

Upstream bonded channels

Channel Frequency (Hz) Power (dBmV) Symbol Rate (ksps) Modulation Channel ID

12579998536.8512064 qam4
24620000038.3512064 qam1
33260000037.5512064 qam3
43940000038512064 qam2



Upstream bonded channels

Channel Channel Type T1 Timeouts T2 Timeouts T3 Timeouts T4 Timeouts

1ATDMA0000
2ATDMA0000
3ATDMA0000
4ATDMA0000

 

I think these look ok from what I have read.

Re: SH3 Internet Issues and Power Levels

as you say upstream is fine - ring it in and book a tech - dont get involved just tell them its faulty
