I first got a connection to the internet almost 15 years ago, when Internet Africa piggy backed off the universities network.

I started with was a 14,400 modem. Then I had a leased line connection 28kbps followed by an ISDN connection. Then finally Vodacom 3G.

Without doubt this is the most unreliable connection I have ever had, coupled with the worst backup service.

I really miss the days when you phoned up you ISP and a young techie would answer who new all about IP's, pings, DNS and all the rest of the;

"COMMON INTERNET TERMINOLOGY"

Vodacom seem to have managed to employ the only young people in the whole of South Africa who haven't a clue about modern technology.

IS IT SO DIFFICULT FOR A VODACOM SUPPORT TECHNICIAN TO INQUIRE AS TO THE CURRENT IP YOUR USING, AND TO DO A PING OR TRACEROUTE, TO FIND OUT WHERE THE PROBLEM IS ?

Instead you get the standard;

1. Try reseting your equipment
2. Change your prefered connection type.

From my 15 years internet experience it seems to me the problem is an

"OVER SUBSCRIBED NETWORK".

Last year when the HSDPA network was first started, I had very few problems.

Then month by month, the service has got slower and slower and more unreliable.

The real problems seemed to start when Vodacom introduced new transparent proxy/cache servers, before that I never got timeouts, now for

EVERY DAMN WEB PAGE I WANT TO LOAD, I HAVE TO TRY AT LEAST A COUPLE OF TIMES BEFORE IT IS EVENTUALLY DISPLAYED.

But worst of all I used to have a rating of 1800 on the MSN gaming network, my current rating is 1100, SOLELY because I get disconnected 9 games out of 10. When you get disconnected its counted as a loss and your ratings suffer.

I cannot believe how ABSOLUTELY CRAP this Vodacom connection is.

When I had a 28kbps permanent connection I used to have uptimes of 3 weeks or more.

This last month the current uptime is approx 20 minutes


So what is the problem Vodacom ?

Interesting article from Mail & Guardian

Says Goldstuck: "I use both major 3G services throughout the country, and have rarely found them to even remotely approach advertised speeds, let alone provide consistent speed. The result is a consistently negative online experience, particularly for applications that require a consistent stream of activity, such as video conferencing and viewing video news clips online."

So, demanding web surfers may find that 3G technology is still a crippled service that bears little relation to what is advertised. "None of the 3G services can compare to ADSL for efficiency, while my 512KB-per-second DSL service is significantly faster and more reliable than the 3G services," says Goldstuck.
 
I must admit this new thing where you have to refresh web pages 2 to 3 times before they display is getting very boring. Is it happening everywhere or only in KZN.

Resident conspiracy theorists may perceive that its a way to boost Vodacoms revenue after dropping their data rates!
 
I use both VC and MTN 3G/HSDPA (VC at home and MTN at work) and agree that the speeds have dropped substantially since HSDPA was released (on both networks). On VC I actually now only subscribe to ordinary 3G data bundles as I rarely get anything above 3G speeds nowadays. When HSDPA was released I regularly got over 1MB/s. 3G/HSDPA is overhyped IMO.
 
More people using the same system and vodacom doesn't have to pay to upgrade or increase capacity. It sounds pretty good for the profits, but no good for us.
 
I'm suspicious of the oversubscribed network theory because problems seem to be related to the time of day your online.

The problems don't occur at random, which would indicate a hardware or software problem.

There is current known (but not yet fixed :() problem on the network. The guys are working on getting a fix out.

You're right that it is capacity related, but not at all in the way you'd expect. The problems over the last few weeks started when we ADDED capacity. And now we have throughput issues. Ironic is it not? It seems certain modems don't quite know what to do with the spare capacity and goes into a bit of a wobbly. We obviously cannot fix it on the modem side, so the network must adapt to this and it requires some software changes.

Not your problem at all, just out of interest; With one of the largest (I think we're in the top 3) HSDPA networks in the world, and a user-base rivaling ADSL in this country, we do seem to 'discover' situations the vendors have not seen before.

Good to hear that there is a fixable problem - thxs for the feedback v3g.

No problem, I guess all problems are fixable. It's more a question of how quickly it can be fixed.

The bulk of problems are discovered and fixed before most subscribers even know about it, some involves help from the userbase (like the time you helped with the 'downlink stop' problem) and others seem to take forever. (Won't mention PPDB's :()

v3g FYI dont know if its relevant but the problem seems a whole lot worse on sites that you have to log into (same as that weird problem a while ago).
Thats why its so difficult for us as we capture a lot of info online and you never know if it has updated or not!

Running a stayalive/ping definitely helps but does not solve the problem completely.

Care to elaborate on "a bit of a wobbly", is there a work around ?

I know some of the modem manufacturers have open source drivers, so it must be possible to hack something together that works.

I had the exact same problem with logging onto web sites, you could browse them slowly, but you couldn't log on. I found that IE was the only web browser that would work for logging on. But Opera and FireFox wouldn't work. But then the problem went away after a week.

I've noticed that too, maybe static sites are loaded from the cache/proxy whereas sites you have to log into aren't?
 
I had a problem with https sites with Firefox and think it may be interrelated to VC current network problems as I know I have used this site before with this version of Firefox with no problems.

The logons were intermittantly successful and if on, I generally got stuck somewhere in the operation hierarchy. Seemingly no return from the server yet hhtp pages were coming in fine.

Going into Windoze and iexplorer shocked me with the ease with which I completed. Firefox in Windoze behaved the same as FF in linux - a dog on https.

Solution: enter "about:config" in the FF address bar and on that page double click on "security.enable_ssl2" to change it to true.

Yes folks, FF by default disables ssl2 due to security concerns and that may cause problems.

Now I can internet bank on FF again under current VC network conditions. Or so it seems. Is my testing exhaustive? Of course not... :-)

Is the capacity your upgrading, Antenna capacity, or internet capacity?

I thought that each antenna had a fixed bandwidth that it shared out among its clients, and you therefore have to add base stations to increase capacity ?
