[HD2 General] chrisnash:
I posted on here a few days ago and have been trying to monitor the behaviour of this.

From todays observations I am totally convinced that the problem (certainly in my case) is network related.

I only noticed this problem relatively recently - about a month ago - and in that time I have tried a few different roms and setups (including roms I used before this issue started) and none of them have made a difference to this repeated behaviour.

In my situation, it is definitely not due to poor signal because I usually have 4 bars of 3G or H when it happens.

I had a suspicion, as someone else posted a while back that it was time related - usually occurring between 5pm and 7pm as the other poster suggested. Only problem with this is that I am normally in the car going home at that point with my phone in the cradle so it is more noticeable at this point. Also I am using it more - watching mail, google maps, streaming music. I'm not convinced it is time related any more - but I'll come to that in a minute.

So then I decided to look at my usage and see if it was particular apps that had a problem.

The one I have started using a lot recently is nanoGroove. The reason I have started using it so much is that last month I negotiated a mega data deal with my network and now have a truly unlimited data allowance (not a crappy 500mb unlimited!) so I can afford to stream music all the time.

NanoGroove certainly has lots of problems and was always losing connection. So I thought it might be related to this. Problem with this is that the service can often be unreliable as GrooveShark are always fighting against the free mobile apps. So it is unlikely that this would cause the problem but it did help me to identify what I do think is the problem.

I began noticing that nanoGroove would start having problems at a certain point on my journey home and so comes todays experience...

I was on my way to work in the car this morning (rather than on my way home as with all the other times and I noticed ActiveSync was having problems - icon continually spinning and saying 'Synchronising' but not actually getting anywhere. Google maps wouldnt pull down a map and I couldnt load BBC Mobile with Internet Explorer. All this whilst showing 3-4 bars of 3G or H. Eventually after about 30 mins in the car it all started connecting again.

Then this evening I set of at 5pm on my way home, stuck on nanoGroove and began streaming music. Tracks were loading fast and fully buffering in about 10 seconds. I played about 6 or 7 tracks then at a familiar point in my journey it all stopped working. Even though I was showing 4 bars of H it was showing it wasn't connected. I pulled over and started checking other connections. ActiveSync wasn't connecting so I soft reset. Opera 10 wouldn't load BBC Mobile, Internet Explorer would load BBC Mobile, Skype connected and showed online contacts, Opera 10 loaded BBC Mobile without images, nanoGroove wouldn't connect at all, Google maps only seemed to be loading cached maps, launched myPlayer which prompted me to update and then began downloading update very very slowly.

At a certain point on my journey, then downloading app suddenly sped up and finished the second half in about a second.

I checked all my other connections then and they were fine - even nanoGroove!

All this happened with full signal all the time pretty much.

A few things were interesting for me;

1. it was sooo obviously location related - same geographical area this morning and this afternoon

2. Some apps were more severely affected than others (suggesting networks restricting particular types traffic?)

If anyone is interested I was in the Hammersmith area when I started to have all the problems.

Only thing I can do now is try the same location repeatedly at other times (difficult as I would have to change my work patterns) and a different location at the same time (difficult as I would have to change jobs!!!)

Anyway keen to share my thoughts and see if anyone is noticing similar behaviour.

I'm in London on Orange (different roms and radios)
