Have any of you ever known the MTU setting in the Network Tab on a Rocket M2 (AP) to change itself? I started getting calls Sunday morning (primarily from Mac users) saying some of their websites wouldn't load. To make too long of a story short, I found that the MTU size was set to 1492 on the AP. (We do use PPPoE, and the MTU on the CPEs is set to 1492.) It should have been 1500. Changing it back to 1500 fixed all the issues.
My question is this: Other than me, no one has the password to get into the AP. I hadn't been into it in many days (or weeks). Yet somehow the MTU size changed and it obviously happened sometime between Saturday (when things for my users were fine) and Sunday morning (when things became hinky). There were some storms in the area, however I don't believe there was a lightning strike (as if that would only change the MTU setting and not affect anything else on the radio, or the other 11 radios on the same tower). There *was* a bad port on the Netonix switch it was plugged into, however as with a lightning strike, I wouldn't think even a shorted port on the switch would change only that one setting - I could see it defaulting the entire radio, but not one setting like that. Anyone ever seen anything like that? Thanks Sam _______________________________________________ Ubnt_users mailing list [email protected] http://lists.wispa.org/mailman/listinfo/ubnt_users
