Possible fix for "Connected but no throughput" - E1820

[Afromee]

Hey

If you don't want to read my whole story, skip to the end, the solution is there.

So my E1820 have been working on and off for the past 8 months, more on than off, however this weekend I bought myself a new motherboard, and had to format my computer.

My speedstick didn't like this at all. Installed the software from the speedstick, tried it, connects fine yet no throughput whatsoever, 0 kbps download, with some uploading going on.

I installed this last, after all my drivers and software, so I though, why not reformat again, and try it first, maybe something was interfering with my modem drivers/software.

Additionally, I thought, why not try a different hard drive as well. Formatted again, this time installing the cellc software before anything else, it worked on and off, but after a few minutes, no throughput again.

POSSIBLE SOLUTION:

So I reformatted my computer again, installed graphics drivers, motherboard drivers, and then cellc dashboard, no luck. Connects, yet no throughput at all.

So I decided to try something, I unplugged the modem, inserted a usb extension cable (in the same usb port), the extension cable is about 1m long, inserted the modem, and believe it or not, it reinstalled the drivers, and there was a small white notification in the right bottom of my screen saying updates available, so I double click on it, and it opens a cellc updater that updates something (probably drivers) because it was very fast.

And since then no problems with throughput.

My current driver version is 2.0.6.704

And if your wondering, I did read every thread on this problem I could find over the past 3 days, installed, reinstalled, modified, tried everything there was, and this is why I'm posting this, because it worked for me, maybe your lucky and it works for you.

And btw, my modem now hangs 30 cm away from where it was plugged in at the back of my computer.

I don't know where to check the dBm on the new dashboard, but I know from when I was using the old one when the modem was directly inserted into the computer it was -75dBm to -80dBm.

Interesting things, because if you plug to the same port (even using extension cable) it shouldn't reinstal drivers (new hardware found message). My feeling is that it installed USB 1.1 compatibility mode drivers. You can verify it in Device Manager by selecting View -> "Devices by connection" whether drivers are linked to something like: "... USB Universal Host Controller", or "... Enhanced ... USB 2.0 Controller ....". The wording might be different, but a key is "Enhanced" vs "Universal".
Generally it is not a solution, as extension cables make it usually worse. On the other side repositioning modem could help reception, particularly if obstructed by the metal computer box or cabinet when standing on the floor. If it works, is fine. However you should also try self powered USB 2.0 hub.

What are you going to do with old mobo? It looks like is a good stuff!

You might get better results if you plugged the modem into a powered hub. The voltage drop experienced by the modem is the main cause of it dropping the signal. My solution (since I also wanted to share the connection easily) was to plug the modem into a 3G router which also has a decent power supply.

I notice that when I take the 3G modem with me and plug it into the laptop, it sometimes drops the connection a few times during a 30 minute session. Using a powered USB hub stopped that from happening.

I have a USB extension, came with a now defunct K4505z (Vodaphone modem), which I use, it has 2x USB connectors, for connecting to the laptop, it is not too long, and I also don't have the modem sticking out the side of the laptop, an accident, looking for a place to happen, if you ask me. When I really need some more distance, from the laptop, a powered hub also serves me well.
