Rocket HUB wont connect to 3G anymore ( med signal)

For the past 1 1/2 years my Netcomm 3G10WVR2 HUB worked just fine with 3G (with the usual outages etc.) with low to med signal strength
Suddenly , about 3 days ago , it stopped connecting in the evenings (no signal,no 3G) and now it won't connect to 3G at all (shows no signal or 3G).
Tech support had me roll it back to 2G and it worked but is quit a bit slower.Shows full signal strength and connects to 2G.
Anyone else ever experience this problem , have any idea why it's started all of a sudden or how to resolve it?

its also possible the 3g band in your rocket hub crapped out and died? it may not be likely, but its definitely possible, the only way to test is to put your sim in another device/phone and see if the 3g signal comes on, if it does, you have a defective radio in yor rocket hub

@BeerHunter125:

 

we use the Ericsson W35 RocketHub.  We moved to a new location several months ago, and I began encountering problems as well.  In the previous location I had used an external antenna.  Without the antenna I would get low signal strengths, and spotty to no Internet.  Voice was always fine.

 

In the new location we had low to moderate signal strength, but Internet would cut out.  Then I put up the external antenna, and now get high to max signal strength and things are as "fine" as they ever get on the Rogers network.

 

I was always under the impression that I needed 3G+ to get Internet connectivity.  Perhaps the Netcomm works differently.  I looked at the management interface for the W35, and I don't think I can "roll back" to G2.  all of the options that would select G2/G3 or whatever are inactivated in the Rogers variant of the W35, even though they show on the user interface.

 

The W35 documentation shows that such things can be set/modified using the CLI, but so far, I don't know of anyone who had access to the CLI.

 

Are you using an external antenna?  If you are not, that could be one way to improve your signal strength and better the situation.

So what does Rogers do for a customer when the hub craps out?   Do they offer up a replacement regardless of the unit's age or a discounted price on a new one when it's out of warranty or do they just do nothing?

@BeerHunter125 & eddy:

 

as far as I know, these devices have a 1 year warranty from Rogers, and after that you are on your own.  I could be wrong on that, but that is the way I remember it.

 

But, it must be that the full moon is waxing.  Last night my cellular signal strength crapped out, and I had no end of trouble getting an Internet connection through my W35.  I suspected the WiFi might be a problem, as I have had some glitches there recently.  Using well-established Rogers troubleshooting techniques, I restarted the 'Hub, but no real improvements resulted.  Well, one can only hope.

 

And pray too, I guess!  Perhaps someone can post some effective prayers to the Goddess of Technology for our use.

 

  So I connected to the 'Hub by ethernet cable.  At that point, cellular signal strength seem to recover, and my Internet connection did as well.  This morning before leaving for work I noticed that cellular signal strength was in the crapper again.  Wonder, what is happening?  Did someone park an 18-wheeler in the wrong place, and it is deflecting all that good Rogers cellular signal away from me?

 

So, what to do?  Well, at the risk of further complicating things, I think I will put in one of my trusty old Linksys WRT54G routers to do the WiFi AP function, and connect it to the 'Hub by cat5 cable.

 

But the key thing is that we have in the past had the cell network cause us grief on so many occasions that I quite frankly don't trust its reliability.  The troubleshooting process is always one of ranking likely risks of failure and prioritizing our troubleshooting activities to be the quickest in leading to a successful resolution.  So, at what point do I begin wasting time on the phone with Rogers support only to be disappointed with their advice once again?  Note that once in a while you do get someone who is truly helpful.  But like with the cell network itself, the odds of that are not encouraging.

 

As usual, I really don't need to spend a number of hours troubleshooting this kind of problem again when I am actually trying to achieve something useful using my Internet access as a tool to get results and rack up some "accomplishments".

 

Fixing the darn thing when it is broken is really not my idea of a good time at this point!

Don't think it's the HUB because it's been on the 3G network (with 3 out 5 bars signal strength) again since yesterday morning.I'm on pins and needles waiting for it to crap put again.

Have a yagi antenna to put up but will probably have to wait until it warms up before I venture up on the roof top (-20C and snow on roof is knee deep) to install it. Luckily there is an existing tripod and 10' pole still up there from my old WiFi days so installation should be a snap.

Aiming and fine tuning it will be another matter...

I have a yagi and it is mounted about 8' off the ground.   You probably don't need to be climbing onto the roof.  The hub is not line of sight as I understand it.   If you mount the antenna under the eaves it has to be something like 3' below so as to not interfere with incoming signal.   The signal comes in as a arc leaving the tower arcing downwards onto the antenna thus the distance below the eaves/soffit area.  Pointing the antenna is what is important.   It will take a bit of time to line it up and get that perfect reading so small movements and waiting periods will occur.   My own results with the antenna attached are 4 bars to full bars constantly.  Prior to using antenna 3 bars and occasional jump up to 4 bars.   No difference in speeds with or without antenna.

It should go on the roof as we're surrounded by 30' to 40' Aspen and Spruce. As you said , not expecting an increase in speeds , but a more reliable , solid signal and want to tie it into a cell phone booster for better coverage in the house for the phone.

 

Re: Rocket HUB wont connect to 3G anymore ( med signal)

It's that good old sixties mantra: higher is better!

 

With UHF and microwave signals a direct line is optimal.  Otherwise you get reflections, attenuation of the signal and multipathing, all of which causes issues.

 

Depending on how directional your yagi is, pointing it in the right direction is definitely of value.

 

What frequency range is the yagi designed/optimized for?

i still think its a defective PA in the device, blown hardware. have u tested it out to make sure?


Re: Rocket HUB wont connect to 3G anymore ( med signal)

@paully:

 

I don't think any one of us has totally discounted the possibility of it being blown hardware in the Hub.  It just seems less likely given that the problem comes and goes with time of day, or whatever.  If it is a hardware problem, it would seem to be intermittent and somehow affected by time of day-related issues.

 

Certainly, if another (known good) hub could be substituted for the current one, it would prove the point one way or the other.  And, I am sure that would be done if another hub were available.  But, lacking that we can only proceed using other options in order to eliminate those which can be addressed more easily.

Doubt it's the HUB since it's working just fine for the last couple of days. All is back to normal.3 /5 bars and 3G access.

 

The Wilson Yagi covers the 900 (IIRC) - 2,700 signal spectrum.

 

Re: Rocket HUB wont connect to 3G anymore ( med signal)

@BeerHunter125:

 

Perfect!  That's the antenna I use as well.  It actually is not a yagi, but what is called a "log-periodic" design.  The issue with Yagi antennas is that they are really good for a narrower frequency band.  The log-periodic antenna is known for its effectiveness over a wider frequency band.

 

You may remember the really, really long yagi antennas that used to be popular for specific TV channels and effective over a long distance.

 

Another benefit of the log-periodic design is that they are not quite as directional as typical higher gain yagi antennas.  As a result your accuracy in pointing the antenna at the cell tower will not be so critical.

 

I'm expecting you will get good results with it.

I Plan to Stick Around

try a speedtest.net in the early mornings or ver late ate night I believe all you guys will see an double speed increase..i doubt its hardware my netcomm has been doing the same, also could be rogers reconfigure things as lte on some towers will be the top tier for the bandwidth on there microwave backhauls...i even believe rogers is putting some rocket hubs on a lower tier trying to minimize overloading the network... just look at all the mail in this thread with similiar problems your equipment very unlikley, rogers more than likley trying to deal with an over saturated network.

Re: Rocket HUB wont connect to 3G anymore ( med signal)

@hogwild69:

 

I have many times experienced differences in RocketHub performance relating to time of day.  Most notably, I have experienced not just reduced speeds, but total disconnects at high-traffic times of the day.  I have experienced these in at least three locations across southern Ontario.

 

Network management techniques could be used to modify the priority of certain types of traffic on the network.  But we as customers do not have a "window" into Rogers' network management practices.  How can we tell what is happening?  I suspect that the front-line Rogers CSR's also do not have that kind of knowledge or information.

 

So all we can do is work with the tools and resources available to us.  We at our end are faced with the requirement of optimizing our home infrastructure, and using whatever measurement and management tools are at our disposal to determine both whether Rogers is meeting their contractual obligations Smiley Frustrated to us, and that what we can control is working well.

 

I doubt that Rogers is reducing the priority of RocketHub traffic specifically.  I suspect that any such move would affect all non-LTE data moving into the network at large, and would they want to do that?

 

The major issue I suspect is, as you put it an "...over saturated network...".  This seems to be true all over Canada, but also specifically in locations where there is either a highly variable amount of traffic during the business day (alongside busy major Highways such as the 401), or significant growth in the customer base ( here in Milton, ON, where houses have sprung out of the ground like mushrooms over the last two years).
