Re: Live services taking long time to access

I don't think the situation is as simple as that but I

will readily admit to being wrong in that respect.

On the off chance that Ditte could do with a control

sample (eg from another marginal area) I will PM

those details that were requested in another post.

Re: Live services taking long time to access

Details PM'd to Ditte ...just in case it is useful.

 

Earlier the status showed a single bar and

the text CONNECTED but the HD Traffic

animation just circled. Later HD Traffic worked OK.

My interpretation is that the product was apparently 

sync'd with Vodafone (hence the CONNECTED text)

but that onward connectivity was not available.

Vodafone or TomTom? Hard to tell. It would be to

TomTom's advantage for its programmers to code

an error display that stated just such a difficulty...

One that could be logged and monitored for

effectiveness and appropriate adjustment.

Re: Live services taking long time to access

Interesting.

 

The product is inside the cottage, I'm watching its status area.

There 'were' two bars showing along with CONNECTED and

HD Traffic was operational. The product is untouched but the 

status bars clear down to nothing. Been so for some while.

Power off/on. Now status is back to two bars...

 

Historically mobile phones attempt sync using full power

until connectivity deemed to be reasonably stable at which

point TX power is reduced to save battery and fried brains.

 

The thread notes that more success is had initially rather

than at length... Perhaps TomTom should amend their

'reduce TX power' algorithm in marginal areas?

Re: Live services taking long time to access

OK today I drove from Newport to reading on the way back called in to Bath Bristol and now back in Newport

 

Newport 3 to 4 bars  15 min to connect  only connected when near seven bridge 

Reading 2 bars 36 sec

Bath 4 bars 40 sec

Bristol 3 bars 47sec

Back in Newport lost connection M4 J27  20 minis later it connected bars 3 to 4 

At home Newport 4 bars 9 min 

 

I have never gone below 2 bars all day best signal Newport and that was the worst connection it must be vodafone

Re: Live services taking long time to access

Here's my latest update:

 

I left work in Cardiff at about 5pm yesterday evening, switched on the device it connected within 20 seconds.  Turned off and on again when I got home (North Cardiff) -- connected again in under 20 seconds.  Brilliant!.. back to how it was before July and matching the service the rest of the country and certainly France get!

 

I then updated the TomTom software (took a chance there I know!) and it woudn't connect at all last night (at least not within 15 minutes)!   I didn't get too worked up - the problem has been acknowledged to me by Mark B at TomTom support.. who says he was in South Wales two weeks ago and was frustrated by the same problem.

 

I switched the device on this morning (on my driveway) and as I got to the network screen (in a new location after the update) it ws connected - i.e. within about 5 seconds.  Brilliant!.. better than the rest of the country!  Then as I drove in I noticed that (at 8am) there was practically no-one else on the road - also fantactic!  Am I naive to think that people have finally realised that public transport is the way forward over paying to park up?!! .. nope, sadly it's just the long weekenders!

 

I didn't add to the discussion beacuse I first wanted to see the same on my journey home today..  

 

... I left work at about 5pm -- 21 (twenty one) MINUTES to connect! (including 10 minutes parked up waiting for my Wife) - with a four bar network signal.  

 

What I noticed on the network screen was that the device was dropping the network signal every 60 seconds.. this suggests to me that TomTom devices try and connect to the mobile network data (Vodafone) for 60 seconds, if no success within that time they 'drop out' and start again.  So, whilst the digital network signal may be strong, when the TomTom is taking 20 minutes to connect/login to the data element it's actually attempted a 20 times!  Utterly ludicrous!..

 

..all Mobile networks (and I have friends who overpay on Vodafone!) start transmitting data to mobile phones 5-10 seconds after mobile 'data' is switched on (in Cardiff at least - London can be troublesome, but still it only takes a couple of minutes at rush hour) -- so it seems that the Vodafone network servicing South Wales is treating TomTom devices with absolute contempt.

 

Question is are TomTom's contract lawyers on the case?!  Do they even care?!

Workaround? Does a manual hard reset (30sec PWR

button until the drum roll) improve connectivity after you're

aware that the product is virtually locked into that utterly

pathetic '60sec dropout then retry' zone? The same goes

for the 'FLIGHT' mode eg switch into FLIGHT to switch

off connectivity attempts then switch off FLIGHT mode.

Interesting... I'm not a network guy in particular...but I *did* have to delve pretty deeply into connectivity architecture several years ago, and I recall having to deal with similar issues when remote devices (or applets) were attempting connection to a server, and the default strategy used in such situations. Your comment immediately brought that to mind. It's actually pretty common when remote connections don't hook up properly to retry a few times -- and then slow down how frequently the retry is attempted. This could be for a variety of reasons, such as not flooding a port with unhandled connection requests. Also: telecom ports have finite limitations on the number of unhandled connection requests that can sit there before the port actually starts dumping the new incoming requests. The real problem with this is that, if it's not tuned properly, a brief outage can snowball into a major outage or slowdown simply because all the devices attempting to connect retry so many times that the incoming connection queue simply gets swamped.

 

I really have no clue about the innards of the way these devices connect to the server...but it's conceivable that when the carrier (Vodafone?) creates a brief outage, the PND's aren't necessarily handling the lack of connectivity in an optimized fashion, so it creates a firestorm. All speculation...just that your post brought me back to the situation (when we had a game site with 100,000 people attempting to maintain connections to our servers all at once)...

 

Sorry - didn't mean to divert the thread... carry on! :manhappy:

Re: Live services taking long time to access

...that's certainly food for thought. Personally I had a local problem

with my village telephone so-called satellite exchange. It took me

almost a year to persuade British Telecomm that THEY had

a noisy uplink problem and THE issue was not of my own.

It could be that TomTom (the customer) might have just such

a problem with their own big telco. Ho Hum.

Re: Live services taking long time to access

 

Same problem in the Bridgend to Newport to Barry triangle over the Bank Holiday weekend and this morning .. 5-20 minutes to connect in this region.. a matter of seconds elsewhere.  

 

Whatever the cause we're not being provided with enough information about a resolution.  Where's the TomTom 'list of outstanding issues' page to update us in near-real-time?  Would this even make it onto that list?  Are TomTom actively doing anything? Is this sat in a  pile of 'higher priority' problems?   We just don't know -- a terrible service.

 

Vodafone's 'monthly update' is telling us that they've "upgraded" or "enhanced" 2G and 3G across the Cardiff area to provide "faster" and  "more reliable" connectivity!
