When I use the promotional 2gb speed stick, I can ping websites, but they will not load in any browser.

Strangely if I use my MTN Sim in the speed stick it works just fine, loading web pages with no issues. Even more strangely, if I use the Cell C Sim in my smart phone, it also works fine, loading web pages, no problem. But the Speed Stick and Cell-C data Sim together is a no-go.

Anyone else experienced this or can figure out why this is happening or how to fix it?

Are you able to open www.cellc.co.za using the Cell-C SIM card in the Speedstick?

No. I clicked on the "Home" icon in the desktop app which took me to the cell-c web page, but like other web pages it did not display. Requesting url..., waiting for..., and then nothing. Can ping the domain, but not view the website. I'm using the Cell-C Sim - via my smart phone's internet sharing - to write this. So no problem with activation or data allocation. I would suspect a faulty speed stick if it wasn't for the fact that my MTN Sim works fine using it.

This behaviour is the same on 3 different pcs.
 
Make sure that your browser is not trying to connect through a proxy server (if you are not using internet explorer, some browsers use the system default, as set by IE), so the best bet would be to check IE first for proxy settings, and then try to open page

No proxy servers in use.

Sounds like you have a DNS problem.

I can ping any domain name... so DNS does not seem to be the problem. It can find the websites, just not display the web page. It reminds me an MTU type issue, but I can't imagine why that would happen, or how to fix it.
 
GateCrasher try and visit the IP address instead of the Home address like for example pinging www.l.google.com [155.232.240.19] visit site http://155.232.240.19/ tell me if it page loads if so then it is a DNS PROBLEM.

Also do the following in command prompt : ipconfig /all
PPP adapter MDMA:

Connection-specific DNS Suffix . :

Lets see what your DNS Gateway and DNS server is

Putting in IP addresses makes no difference.

The output with the Cell-C Sim in the Smartphone (working) is not compatible as the phone is acting as a router.

You can set your MTU to 1500

Same results regardless of host.
 
Added an MTU entry of 1406 into the registry (tcpip/Parameters/Interfaces) and this worked. So it is definitely some kind of MTU issue. But why? :wtf:
 
I have a very similar problem. With my 21mbs (black) speed stick with the Cell C sim i can connect to the Internet but it keeps disconnecting after every 30sec to 1min the whole time!! Put in my MTN sim card, the speed stick works with no drop in connection and everything works like it should. Put the Cell C sim card in my Sony Aino and install software on my SO's laptop (Vista) and tada, works fine, did not drop once and worked for hours on it. Also used it like this on my tower and no problems.

So the speed stick works, just not with the Cell C sim?? What could cause that?
 
Typhoon, with the cc sim, does the modem only drop the internet connection or does it disconnect from the USB port in windows? I have a suspicion that cellc causes my modem to crash and then reboot. My e1820 works AOK with my mtn sim with even a weaker 3g signal. But im still running tests to confirm this.
 
It will actually tel me its disconnected, then it needs to pick up & authenticate again. Its like u said, it looks like somebody pulled out the dongle and then plugged it back in, in a matter of 2sec. With my MTN sim i run on 2 bar 3G strength the whole time without anything dropping or disconnecting. Im sure something with the Cell C sim & the dongle is not corresponding. Cause the Cell C sim works fine in my phone when used as modem. So it might very well be that the Cell C sim or network is causing the modem to crash or something.

One other suggestion, check that your modem is in RAS (modem) mode and not NDIS (network interface) mode.

I have noticed the same with MTN you can have RSSI -97 and you will still be able to ping websites,visit websites, download etc, but on CELL C over the last weeks if you had such RSSI level you were practically unable to do anything but Reset your connection to woooooosh a couple of times

What I noticed about the BLACK Dongle very sensitive - for example if I touch the modem it will un-plug and plug-on again - this doesn't happen with the white dongle poor design on the black dongle in my honest opinion.
