Anybody knows what's the reason for this? OTB settings in RouterOS, apart from unchecking the "dial on demand" checkbox in the PPP connection.
I was thinking that the odd behaviour maybe can be cured with a firmware upgrade of the MiniPCI-e card.
This card is discontinued for years by Sierra I reckon, but I managed to find a .TAR file somewhere on the net, containing version 22.214.171.124 which appears to be the latest.
Or does anybody know of a newer version?
And what is the "official" and approved place to look for such?
Anyway, the .tar contains the following files:
19.09.2008 18:13 164 FWUpgradeConfigFile.txt 12.12.2007 23:47 234 279 MC8775QCOM_H126.96.36.199.cwe 30.08.2008 05:42 13 393 280 MC8775_H188.8.131.52.cwe
Running 6.2 I see there is a setting /port/firmware which I assume is intended to specify location of firmware image files.
Documentation for ROS is very limited on this point:
Firmware Sub-menu: /port firmware This submenu allows to specify directory where drivers for 3g modems can be uploaded and used.
So what is the correct procedure for installing firmware on 3G MiniPCI-e cards?
And which HSDPA or 4G cards do you recommend these days?
