RouterOS General

Hi everyone;

I have RB411U and Sierra Wireless MC8790 3G card combination and I know MC8790 is in supported hardware list.

I am using OS4.5 and try OS4.6 as well but I can not get internet connection with 3G.

can anyone give me a suggestion to solve problem?

thanks.

My 3G card can connect 3G network properly but there is not any rx/tx data throughput.

I realized; #0 route is only DS, how can I switch to ADS because wiki page shows ADS for relavent route address

at winbox;

Gateway:188.38.52.220 is showing unreachable.

why?

but when I put check to “dial-on-demand”, Gateway is showing reachable in that case 3G card can not connect to 3g network and says " waiting for packets"

Problem solved, I can connect 3G network and I can surf Internet via RB411U+MC8790 combination.

Problem was add-default-route=yes, don’t enable that in UMTS interface and add manualy route with gatewat=ppp interface as UMTS connection.
