Randomly Rebooting Superhub - Very Annoying
 

Hi All,

I have had a Superhub with 20 MB BB since earlier this year and until the last fortnight have had no problems whatsoever. However, for the last couple of weeks, the Superhub keeps randomly rebooting itself and going back to default settings. I reckon this must have happened around 10 times within the last fortnight.

I am not actually having any problems with the BB, just find it increasingly annoying that the Superhub keeps restoring factory settings and losing all my settings.

I would appreciate your help in advising whether this is a faulty Superhub, an issue with a recent firmware upgrade (currently V5.5.2R30) or my signal, I attach my connection details below -

Your downstream is too high but the reason the hub reboots is because its a heap of junk.

I had the same issue with all 3 super hubs and my signals are perfect. Changing the wifi speed to 145 helped but in the end I got myself a dlink-615 and its been rock solid ever since.

Re: Randomly Rebooting Superhub - Very Annoying
 

Hi Guys,

Been trying to sort this issue via the VM forum and I currently have a new Superhub on it's way. However I've just posted the message below on the VM forum but wanted to copy it to CF too for any advice anyone may be able to give regarding my question about the downstream channels -

--------------------------------------------------------------------------

Just a quick update, the existing Superhub has rebooted itself again and gone back to default settings.

Looking on the connection page I have 5 downstream channels as follows -

Downstream Channels
Lock Status Modulation Channel ID Max Raw Bit Rate Frequency Power SNR Docsis/EuroDocsis locked
Locked QAM256 80 55616000 Kbits/sec 299000000 Hz 6.9 dBmV 43.2 dB Hybrid
Locked QAM256 79 55616000 Kbits/sec 291000000 Hz 6.9 dBmV 43.2 dB Hybrid
Locked QAM256 81 55616000 Kbits/sec 307000000 Hz 7.1 dBmV 43.3 dB Hybrid
Locked QAM256 82 55616000 Kbits/sec 315000000 Hz 6.8 dBmV 43.3 dB Hybrid
Locked QAM256 83 55616000 Kbits/sec 323000000 Hz 41.6 dBmV 44.0 dB Hybrid

I know that when the tech visited the other week, he said I only needed to worry about the first 3 channels (79 - 81) for my connection but can anyone advise wat channels 82 and 83 are for?

The only reason I ask is that channel 83 always seems to always have a really high downstream power level and the last couple of days my Superhub has remained stable in modem mode but on checking the connection settings yesterday, channel 83 was been at around 7 dBmV. It has now shot up again to 41.6 dBmV and the Superhub has rebooted again.

I am therefore putting 2 and 2 together (and possibly making 5 as I'm no tech but like to think I know a little about these things) but am wondering if it is this channel 83 that is the cause of my problem as I only ever had 3 downstream channels in the past and have never had an issue with the Superhub. The two new channels appear and my Superhub starts rebooting everyday.

Is this channel 83 the channel for the 100MB broadband? Was the tech who visited the other week actually correct?

Grateful for anyone's advice although I will still try the new Superhub once it arrives.

Cheers

I think you must all be imagining these issues. Masque's Superhub is perfect and there half a million others out there all working perfectly too apparently.

Mind you the five I had were all unfit-for-purpose junk....

Re: Randomly Rebooting Superhub - Very Annoying
 

My channels looked like that when they went to 5. Your "rogue" channel 83 might sort itself out after a day or so, mine did.

I agree with jb66 and kwikbreaks in that the superhub as a router is absolute junk and not fit for the purpose.

You might cure your issue by changing the mode to 145mbps, the band to 2.4ghz and then manually frigging about with the channel selection until (if you are very lucky) you find one that is stable. The problem is, it only takes one of your neighbours to change their channel or a new router to start transmitting and you will be dumped back into the same situation and have to start again. So, IMHO, any solution you find is only ever going to be temporary.

The only thing to do is acquire a decent router (check out TP-Link who seem to be at the right price and get good reviews) and switch your superhub to modem mode.

It works and it does its job and the majority are the same, sorry if a few facts get in the way.

Re: Randomly Rebooting Superhub - Very Annoying
 

To be honest, until this past few weeks I've had no issues with the Superhub. It all seems to have coincided with the increase in downstream channels. I have a feeling it is something to do with that channel 83 and the really high downstream power. However the VM tech and forum didn't seem to see this as an issue so may be wrong. Strange coincidence though, 3 channels = no probs, 5 channels = daily rebooting!

Re: Randomly Rebooting Superhub - Very Annoying
 

Mine was junk with 3 channels, junk with 4 channels, junk with 5 channels.

It seems a bit of interference completely overwhelms it.

Re: Randomly Rebooting Superhub - Very Annoying
 

oh come on masque, wake up

if your going to say "sorry if a few facts get in the way" then maybe you want to get those facts and quote them here.

The majority.....
- Dont want a combined device
- Dont like the cheaply made superhub
- Think that its rubbish for many reasons
- Random Re-booting - cant cope in a range of circumstances
- Lack of features (on the so called "premium product")
- Wireless range utter crap
- Would like customisability in a router
- Stability not very good (apart from your one which has been baptised and blessed by the docsis gods


There are also many more issues, but the above cover "the majority"

I know i mentioned the wireless being crap, when of course yours is perfect, but if I recall, your using a second access point for your wireless?


I know the above is rather negative and not fitting with christmas spirit, so..
:xmas:

Re: Randomly Rebooting Superhub - Very Annoying
 

To be fair to Masque your definition of majority may not match his - I think your post needs modifying to say ..

The majority who have a clue

Having used the thing it's pretty clear to me that you'd need to be pretty clueless to regard it as a satisfactory device for anything other than the most basic of home routing tasks.

Re: Randomly Rebooting Superhub - Very Annoying
 

craigj2k12 whilst I appreciate your comments above, it appears that you have had a bad experience of the hub and it's everyone's personal experience that matters.

I actually quite like the idea of the Superhub (combined modem / router) as it reduces the number of devices and cables in my set up. I also think it's quite a good looking piece of kit. I'll admit the wireless range isn't the best as it's probably only equal to my old Netgear G white router that VM were providing a few years back. I expected a N standard router to have a stronger signal but I can't really complain as it is adequate for my needs. For my relatively basic needs it has more than enough features on it.

Yes, the rebooting is starting to get on my nerves but this is obviously some issue that has appeared in the last 4 weeks as up until then, it only ever rebooted on a couple of occasions and my service is perfect.

So my overall experience (like Masque's) is relatively good and I will be perfectly happy to continue using the Superhub if I can get normal service to resume as I have had many months of good experience and I am not going to let this one month of issues dampen that as VM have been trying to resolve this for me.

But like I say, your personal experience is obviously of problems with the Superhub and I am sorry to hear that and it is unfortunate but that is YOUR experience. I know many people also have problems on here but this is a forum and you generally only come on these when you have an issue to try and seek assistance to solve it. It's human nature not to come on a forum if you've only got praise for something.

But hey this is just my view and everyone has there own opinions.

Merry Christmas to you and all the other CF members.

Re: Randomly Rebooting Superhub - Very Annoying
 

In fact I too liked the idea of a hub rather than separate devices and actually waited until the Superhub was free on upgrades to 50Mbps. The problem is I also like to have a reasonable control over my home network and expect my phone to work on WiFi pretty much anywhere on my premises (I'm not the Duke of Bedford after all). Despite it's "Super" billing the feature set of the Superhub is very very limited and the wireless range is poor. Once you add in the tendency to reboot if there is any other strong WiFi nearby (better than the hangs before the R30 correction at least) it starts to look very unattractive.

The real problem is the absolute need for a VM provided modem section. If you don't like the BT, O2, Orange, or whoever's supplied hub you can buy and connect your own kit. On cable you can't you're stuck with what VM supply. Putting the thing in modem mode returns the freedom but you're then stuck with an oversized modem with an unconventional and IMO inconvenient connector layout.

Re: Randomly Rebooting Superhub - Very Annoying
 

Hi Superblade

Originally you posted problems when on 3 channels which is contrary to what you say in post #7. But no matter - nobody's really told you what has happened in your circuit nor answered your 5 channels question.

You have been moved to an new high capacity line card, possibly on the same UBR - I can't tell. Your power levels have changed which means they've done some field work as well in your area.

The fifth channel mis-reports the power level due to a SH firmware bug. So nothing to worry about there.

Your downstream will be sent through all 5 channels and is then resequenced in the SH prior to presentation to you. You either misunderstood the engineer or he was joking (I'm being kind to him).

So any problems you're having with the SH may be due to it being used in router mode. The Netgear version of the SH is pretty ppoor when wireless is on.

That's why I use Modem Mode and have my own router. The Netgear SH is a piece of junk as a gateway, no matter what Masque says.

Which brings me to your mild smack on the legs for Craigie. Masque does need taking on sometimes. He uses the SH in modem mode (to the best of my knowledge). Whether or not that is the case, Masque avoids commenting on the obvious stability problem the SH is having when in router mode with wireless on. If you find this "spat" an intrusion to your thread, then apologies - at least from me.

But I hope otherwise that you find the information I've posted helpful.

Re: Randomly Rebooting Superhub - Very Annoying
 

Hi Seph,

Thanks for your response, you rightly say that you are the first person to answer my actual questions. In my original post, I did only have 3 channels, but my downstream power levels had shot up which was the original cause of the original instability I'm guessing. I've since gone to 5 channels and the problem seems to have got worse and the Superhub seems more unstable. A new Superhub is on the way but I'm guessing it probably won't make much difference even if I swap it out.

With regards to the tech who visited he stuck on a 6dB attenuator and said it was only the first 3 channels to worry about. He also mentioned that 100MB was testing in the area and this may be the cause of my fault and that hopefully it would settle down in January. He said he had been told not to swap any equipment until Jan so I don't know whether he'd got the correct info or not? The tech support staff on the VM forum have since said there is no 100MB testing in my area so who knows?

Modem mode was stable for the last couple of days but then rebooted again. I'll stick it back in that and see what happens as I mainly have my laptop wired to it and only use the wireless occasionally for my PS3 / phone.

It wasn't really a smack on the legs for Craigie, just my opinion. Like I say everyone is entitled to air theirs on here and that's what makes it a great forum.

Cheers for the info, makes a little more sense now.

sorry if i was a bit over the top but sometimes masque needs things explaining which he doesnt quite understand :)
