Well, looks like my occasional but curiously scheduled REIN problem is back.
I've been busy, so hadn't noticed it's effects at the time, or had chance to put the radio on and try to track it down.
I've had RouterStats Lite running for just over a week on my Huawei HG-533 (by setting it to Huawei Generic Telnet, which partially works - (correctly logs downstream SNM and speed, but plots bogus data for other items).
The SNM bobs along quite nicely between 8 and 9db, usually nearer 9. When the REIN attack comes along, it drops to a curiously unwavering 6db.
Previously, it would usually happen on Sunday evening for an hour or two, and occasionally on Wednesday evening for a similar time. This time around, it's Saturday and Thursday evening.
I can't think of any activity in this house that would have caused this.
Annoying!
