411UHAR + Sierra MC8801

Hi again,

still have lots of problem with 3g modem and mirkotik router…

now the test is 411uahr+sierra mc8801: when i make a speed test during the upload the the mc8801 stop working and have to poweroff the board.

Similar problem with huawei 820W (works better with 820U, but has other problems)

Now i test 9 different 3g mini-pci cards, NO ONE works good.
All have different problem.

Please give more support about this topic.

Thank you.

are you sure that this is not a complaint to be filed to your 3G provider?

3G modem is recognized, and has connected. Now everything is done in the modem. RouterOS doesn’t affect the speed and latency. Call your phone company

thank you for answer.

I tried with 4 different operators. I have the same problem with all 4 operators.

This problem came only with sierra MC8801. With sierra EU850d works fine, but the speed is very slow.
The problem i have with mc8801 is similar with the problem i have also with huawei 820w. With huawei 820u works better.
With sierra MC8700 works fine for 3-4 days the it freeze for 14/16 hours of watchdog reboot. The, magically, it restart working for other 3-4 days.

Actually i don’t have found one 14.4mb, 21.1mb or 42.2mb model that works fine with your routerboards.
Only sierra eu850d that is a 7.2 mb works fine but slow

Thank you

Leo,
sorry for not interrupting, have you solved your issues with gtm380 option modem mentioned in your last posts?

I’m continuing the train to find the only one working 3g device and of course i mean it has tobe stable. I’m to use gtm380, about one hundred.

So far I’m still not sure if thats the good choice, even though I’ve tested one 4weaks.

Hi,

no. No way to use GTM380. The only one works is the EU850D (in italy with all 4 main operator)

All the other model i tried have all different problem. Impossible to use more then some days without poweron/off the routerboard.

Still searching for a good model…since 1 year of tryes

i have to install N.550 3g hotspot before April 2013 and other N.9000 (!!!) 3g hotspot before Dicembre 2014. Now i have 2 active hotspot (for testing) with EU850D. Very strong, but VERY slow. If i can’t solve the problem before Jenuary 2013 i have to change mikrotik platform with other platform. After 1 year of test i am bored.
