I am currently testing a huawei UMG1831
Okay, I try and see how to configure using dashboard.
I already forced the modem to be on UMTS2100 via MDMA.

But my office the 3G signal is weak so I can't test it out. Need to wait for tonight.

The UMG1831 signal reception is very weak, at my parents place cannot latch onto any 3G signal, and if can it's only 3%

Added on January 17, 2012, 8:43 amOkay, the modem is already on RAS, since yesterday, but even then last night when I was testing the reception was terrible.

And it kept disconnecting and the upload was only 500kb.

Yesterday I didn't force the bands, but today I have. I can't test it for very long because different location

Tonight will test again.

Added on January 22, 2012, 5:48 pmI am experiencing some odd things with the router.
I am not sure if it's the channel width being the issue.

The router is currently set @
Channel 1
mix mode
auto channel width
300mbps transmission

For my own devices, SGS2 and my mom's laptop the wifi does not 'hang'.

But for ipad 1 and ipad 2, even though it shows connected, the wifi is 'stuck' and not seem to be transmitting.

When this happens, other devices that are connected can still work without issues.
Any one experiencing it? and if you did and managed to solve it, any setting change?

purchased my 3420 from cycom for 85

mr3420 + e1762

modem ready to connect for about 4min.getting 45% signal strength only.
at times the e1762 will disconnected after 30 minutes or 1 hour usage. take times to reconnect back, at times need to power off router.

how to settle this issue ya?

ya, does anyone know if the new modem ZTE MF190 (the one umobile use for MB68) works?

chuah, wifi wise I don't have disconnection problem.
Anyway I solved that issue.

Now the issue is that the modem will disconnect itself after some time, maybe its the cell tower. But it happens at 2 different sites.

Hi,
I am having troubles to connect ZTE AX326 modem to TL-MR3220 router. I can't set autorun off. I think it is because in device manager my modem is recognised as Network adapter, not a modem.

I don't know what to do

Hi,

Can I connect my pendrive or external hardisk to the modem's usb port??? To act as a network storage.

hi guy, just recently bought this router, plug in the maxis e173 3.5g modem. i found there is some problems of the wifi connection, around 20 to 30 minutes the wifi connection will die, need to diagnose the wifi of my notebook, then turn back to normal, any1 face that?

i plug in the e173 into my notebook, never have disconnect problems, i think this is not all modem problems, i think is the wifi problems.

Hi, if connect using sony phone
for phone side, need to do any configuration?
or will auto recognize the phone?

great, i got 1 extra SE W705, can test with it 1st...

What is the highest speed that this modem can support? I know certain model of 3G routers have limitation in terms of the fastest download speed, wondering if this router can support HSPA+ speed.

I'm using digi with an unlocked e1762 from maxis. prior this, i'm using an e220 huawei modem. my router can find & dial the huawei. however, the modem has died. so, i'm using the maxis e1762. but my router can only find the modem. detect & tried connecting. but it will eventually showed the modem has been disconnected. i sent to the supplier and they showed that they can use an 1550 from maxis. i'm a bit puzzled. since some of u using an e1762 modem without a problem.
i tried using an original huawei mobile partner in the modem. but the result is still the same.
please help me.

I used Putty to disable MF190 before. The first thing is you need to set correct COM port and then, type the command via keyboard and press "Enter". For my case, I didn't see anything on screen when I typed but if you waited for a while, then you'll see a response from the terminal on whether the command is successful.

Added on February 29, 2012, 10:00 amHas anybody tried Huawei UMG1831 on this router?

Thanks for the info and great to hear that btw, can we get full speed when plug into this modem? Assuming the ISP supports such a high speed...

You're wrong.
I got 21mbps from 1831 when I had it for a week.
But it was unstable cause of bad firmware.
