Router Issues

<< < (2/2)

BigJim_McD:
About 16 months ago I bought a new TRENDnet TEW-818DRU  Wireless AC1900 Dual Band Gigabit Router.

The TEW-818DRU reset itself to "Factory Defaults" at least 5 or 6 times during the first 3 days.  I returned it to Amazon and purchased a replacement, a Netgear R7000 Nighthawk AC1900 Dual Band WiFi Gigabit Router. I haven't had any "Reset" issues with the R7000.

Lavarock7:
This was the article I saw that said disable Upnp. There are others but I was in "fix it" mode at the time. I thought I read that external wan traffic could do damage if Upnp was enabled. Anyway, even with wifi off and most everything disconnected, I was seeing IP addresses scan my system. Somebody disabled the router ovrnight. It was obvious because many of the wifi devices stopped also. That happened when they reset the router and the password disappeared on wifi. Soon thereafter I got the "call from 100" call to my phone.

dircom:
I am sure you did not use the default router password, but curious if you considered your old password "secure"

"Someone" is always scanning (whether for good or nefarious purposes, someone is always scanning).  And devices that are "vulnerable" are going to get exploited reasonable quickly (while the numbers are wrong for a whole set of reasons, a few years ago there was an estimate of around 5 minutes before a vulnerable system placed on the unprotected Internet was exploited).

It should be noted that just as OBi's can occasionally lose their configuration due to hardware issues, so can consumer targeted devices such as routers, which often fall back to "default" mode (if a reboot happens, and the configuration appears bad, the system reverts to defaults), and either some internal hardware glitch or perhaps a power glitch at the wrong time can make your life very exciting.  What is often worse is that these "reset to default" operations often destroy any logs that might have helped determine the original fault.
