RB1100AH-X2 clock settings

Hi there;

Does an 1100AH-X2 run @ 1333MHz clock? By default = 1066MHz. Using 533MHz DDR btw.

Any thoughts?

Thanks!!!

Re: v6.40.4 [current]

Hi ...

Cosmetics ...

While cloning config from a 3011 to a 1100AX2, drag'n drop multiple .rsc files from 3011, the 1100 or reboot or close WinBox and don't complete the writing process.

Same files from a folder on a pc to 1100 works ok.

Re: Setup DNS caching

Depending on your network size (from 400-500 users onwards), you may need to increase the Max concurrent Queries setting on IP > DNS.
On version 6.40.X still 100 or can be more (1000, 2000, etc) ?

Re: Switching between NTP Client and GPS.

Hi Eben: Actually an old Furuno GN74 module (1993 or so). But any GPS that have RMC sentence enabled and a serial RS232 port is ok. My module does not have an enclosure. It's just the module itself on a 1 x 3 x 5 cm metal shiled and a 10 pin fence connector somewhere (besides the SMA antenna input)....

Re: Huawei E169

Tested on a regular PC (pretty old, 450MHz Pentium) and got the same problem, so I guess it´s not power-related? Changed the initialization-string to ATZ. It seems to work when locked to GPRS (changed settings from Windows). With autoselect or 3G only I only get the "modem hunged up"-error. Any ide...

Default Gateway & Winbox

Hi ... I saw something around the forum some months ago but I did not found the topic. May be a dumb question. I have a simple config to distribute internet access at home using wrap board with a 3G usb modem + ATH 802.11B/G mini-pci running AP. When I installed ROS for the first time (3.16 I guess)...

Re: Huawei E169

Hi ... I've been around with a E156 some time ago, on PC Engines WRAP. At that time ROS 3.16. Today is 3.21. I don't know if E156 is closer to E220 or E169 but E156 have those built-in virtual CDROM (which carries win drivers) and a Mini-SD card adaptor. Anyway, when connected E156 (may be others) c...

Re: USB Resources on WRAP boards X ROS 3.20

try emailing a support output file from your router to support@mikrotik.com so see why it doesn't show any info in the USB menu. Yes, this is the correct option. Since all USB peripherals was runnig ok I left it this way, waiting for 3.21. Then some days ago I set support output file to support and...

Switching between NTP Client and GPS.

Hi: May be usefull for someone. I'm using an OEM GPS module on WRAP RS232 serial port (ROS 4.01beta1). But GPS antenna is not at the right place yet and sometimes GPS data is not "valid". So there is a small routine to check if board clock must be tied to GPS or to a NTP-Server anywhere, according t...

Re: Clients packet loss on WRAP board + CF Card Licence NR

Thanks dot-bot If you want to use your CF on a PC simply use it in a CF<->IDE adapter, not in a USB adapter. I'm 90% sure it should work then. Problem is in USB adapter interpretation of medium and/or access geometry. Yes, makes sense. I thought use CF on a desktop PC to compare modem behaviour usin...

Hi: I'm a RouterOS home user.

Hi. I installed ROS 3.16 on a 128M CF card, which I switch between 2 differnt WRAP boards (2E and 1E) I'm doing tests. I enabled on both boards the USB feature, normally disabled and unpopulated with electronic parts (ESD ckt, connectors, etc). They're USB 1.1. At USB I have a E156 3G Huawei modem. ...

Hi: I tested E156 on two different Pentium machines (a 1.3GHz laptop and a 2.4GHz desktop) using ROS 3.16. The only way to make this 3G modem connect is disabling VT102 at \system\console and if E156 is the ony USB device must use USB1. USB2 may be the telemetry interface or the MMC/CD interfaces. I...

Re: Huawei usb 3g modems (used by vodafone)

I don't understand, you got access to the AT mode? then RouterOS already fully supports this modem. What happens in AT mode, then is completely modem dependent. RouterOS has nothing to do with that. Maybe you have to contact your mobile provider and work with them, to find out why it doesn't connec...
