No comments - it can only mean that my instructions for using Huawei 1820 HSPA+ modem with ASUA are either useless or flawless.

I found a flaw (see below), so that means...

The flaw is that in the ENTREE section steps 4) and 5) must obviously be done before step 3).


In addition, the following procedure almost certainly works after HSPA+ modem stops working, ie. LED blinking (see the DESSERT section):

1.) Unplug the power chord, wait 20 sec, plug in the power chord

2.) reset to factory default settings by depressing the RESET BUTTON (router back side) for a few seconds, until roter power LED blinks

3.) Login with DEFAULT u/p (admin/admin)

4.) System config / Setting management/ Upload

5.) Login with user/pass saved in the backup configration, that has just been uploaded

6.) Smoetimes the APN specific configuration data does not get restored from backup configuration, so check it under
USB Network Devices / 3G/CDMA Modem and put in manually if needed as in steps 11.d-g in the MAIN COURSE section

7.) APPLY

8.) FINISH / Save & restart



Feedback is welcome.
