Superhub 2 (v26) only locking to DOCSIS1
 
Hi all,

I've had a Superhub 2 for around more than 2 months now and it had always been running fine and connected to DOCSIS 3 (6 downstreams and 2 upstreams). Last week, the v26 update was rolled out and all Superhub 2 in the Witton area in Aston are connecting to DOCSIS1...

I've had 2 engineers out who fit in a new Superhub 2 and checked the Superhub 2 directly from the cab. It didn't lock to DOCSIS 3 so he sent it to the engineer departments. Today, I got a phonecall it was complete... however, it didn't lock to DOCSIS 3 and only has only 1 upstream. I managed to ring level 2 support who said that with v26.. Superhub 2 doesn't lock to DOCSIS3 and that it's a bug?

Does anyone else have this issue.

Re: Superhub 2 (v26) only locking to DOCSIS1
 
Can't really help you much with the error apart from suggest checking the cables are connected tightly, that usually resolves any issues I have with it not locking to the extra channels. However, I have V26 and mine locks to Docsis 3.0, so sounds like you may have been told a lie! :(

Re: Superhub 2 (v26) only locking to DOCSIS1
 
It's a known issue with V26 that was supposed to be fixed before general release I still get it sometimes when I reboot.

Alikhan821 26-09-2013 20:23
Re: Superhub 2 (v26) only locking to DOCSIS1
 
Everything is secured tightly. The fact is I never had the docsis1 issue before v26...the engineer put a 6db attenuator on but it's not related since the previous super hub 2 had errors with no attenuator. It's after v26

Re: Superhub 2 (v26) only locking to DOCSIS1
 
This is indeed a known bug, identified during the trial of Superhub 2, and still present in V26. A reset of the SH usually will get you more downstream and upstream channels.

Re: Superhub 2 (v26) only locking to DOCSIS1
 
Mental note: Don't reboot ever.

Re: Superhub 2 (v26) only locking to DOCSIS1
 
I've just pinhole reset and after an hour.. I finally get internet access. It's still locked on 1 downstream + 1 upstream.

Nedkelly 27-09-2013 22:57
Re: Superhub 2 (v26) only locking to DOCSIS1
 
299 MHz is docsis 3 freq there must be something wrong with the levels for the modem to do this . The super hubs will drop the 6 or 8 downstream channels and go from 2 or 3 upstream channels to 1 it's a self preservation mode it will still let you get on the net but not the speeds you expect . It will go back if the problem goes ie noise on the node or Ingres on the node . W
If the modem does connect to more than 1 ds and 1 us check the levels :D

The fact is that these issues occured after the Shub 2 got upgraded to v26.

Re: Superhub 2 (v26) only locking to DOCSIS1
 
well this says it all doesn't it. Why oh why would you release a firmware update when trials revealed a bug which essentially incapacitates the modem? Even if they thought they had fixed it they should have tested it thoroughly to make sure. This is shub1 all over again; bang out the firmware updates regardless of bugs.

Who thinks they'll have to wait another 6-8 weeks for the next firmware update?

Re: Superhub 2 (v26) only locking to DOCSIS1
 
I have just had to have my shub 2 replaced yesterday after it showed signs of failing, phoned VM on Thursday and had it swapped Friday. Fast response from VM and back on line without to much trouble. :clap:

Could not switch it to modem mode till late last night however.
