Re: Speed keeps dropping

Could you access your router using http://192.168.0.1/ . Don't log in, select the 'Check Router Status' option and paste your 'Downstream', 'Upstream', and 'Network Log' tabs?

At least we can check the stats to rule out an issue with the line.

Re: Speed keeps dropping

Can you set up a Broadband Quality Monitor (BQM) at thinkbroadband.com - this will give you an insight into what is happening with the signal at the other side of the Hub, it will take a few hours to get any kind of trend showing although you can post the link straight away.

Post a link to your BQM on here.

Instructions for posting BQM Link

Under your BQM graph are two links in red.

Click the lower link (Share Live Graph) then click generate.

Copy the text in the Direct Link box, beware, there may be more text than you can see.

On here click the Link icon (2 links chain to the left of the camera icon)

 In the URL box paste the link you copied and then click OK - you can post the link straight away.

Re: Speed keeps dropping

Your upstream power levels appear to be quite low:

Upstream bonded channels

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

1603000003.45512064 qam9
2394000003.5512064 qam12
3462000003.529512064 qam11
4537000003.379512064 qam10

 

3.5 (Or 35 with the decimal in the correct position!) is considered low from what I've seen in other threads.

Re: Speed keeps dropping

This is info from a year or two ago - may have been tweaked !

Downstream: no lower than -6dBmV and no higher than 10dBmV --- Close to 0 is optimal.
Upstream: no lower than 31dBmV and no higher than 51dBmV --- 44dBmV to 46dBmV is optimal.
