My not so super hub started playing up again about 3 weeks ago. Last time when it kept losing connection all the time, I changed the channel to 4 and it was perfect for months, but now changing channels doesn't seem to make any difference. The lights start flashing, the top blue light and one of the green goes off but then they are back up again. It is sometimes fine for a day, but most days this can happen every minute and it's seriously frustrating.
Every time I troubleshoot it, it says that my device is configured properly, but the DNS server is not responding so I am guessing the problem lays within the hub?
I have changed the channel selection to "auto" and it seems a BIT better. I have also moved the hub as far away from the tv as possible but the cable for it is so short, it limits where I can put it to get the best signal.
So overall, I can get a good connection and when it works it is flawless, can't fault it. But when the lights start flashing for no apparent reason and the top blue light goes off, it breaks up and sometimes it comes back on by itself if you give it a minute, but often a device restart or the hub reset are required. What can I do to stop the lights from flashing and going off? Do I need to contact Virgin in order to replace my super hub?
The top Blue Light indicates the Modems Connection tothe Virgin Media DOCSIS network (Blue means DOCSIS3)
If this goes out and is flashing green the modem has lost it's connection to the DOCSIS network. the light below that should be green but while top light flashing green this will not be lit as it indicates that the modem is ready and connected to the internet.
Could you follow the instuctions in the post marked "How to viewyour modems config pages" and post your connection stats and network logs.
I have noticed yesterday that Virgin changed the layout of the settings page therefore I was not able to locate the Connection tab on the left hand side as it is no longer there. All I could find about the Upstream and Downstream is this:
Lock Status Channel ID Frequency Modulation Rx Power SNR Pre RS Errors Post RS Errors
I have exactly the same issues - set up a new super hub yesterday - all fine for approx an hour now blue light extinguishes and get the flashing green top light - logs show 'critical' errors
have tried using hub as a modem and sending signal via zxyel but no luck here either
complete instability and now not working at all - blue light on for approx 2 mins only now
engineer visit tomorrow - will post if solve it but past this will be suspsended my monthly DDs as I am not receiving the broadband that I am paying for - see no other solution - cannot 'tweak' hub 10 times a day for 15 minutes just to have internet access
If it's any help, I have changed the operating channel to 9 and it seems to be working very good now but it could be only temporary. Still worth a try! When I was experiencing the same issues a few months ago Virgin helpline advised me to change the channel and I changed it to 4 which worked great untill a couple of weeks ago. And Auto always connects through channel 6 for some reason which is also no good in my case.
Another thing you can check on your seperhub wireless settings is the security mode. Make sure it matches the security mode on your device/devices because I noticed it is automatically set to WPA Auto which is painfully slow and keeps crashing. Change it to WPA2-PSK (AES).
These might just be temporary solutions that could get your internet working till the engineer comes out to fix the core problem.
