Deleting temporary internet files fixed. Original post follows:
I tried searching Google and these forums, didn't find anything.
I believe the revision of my DIR-615 is C and the firmware is 3.11NA
I just found out (while trying to research my current issue) that there are newer firmwares - I'll have to look into those when I get back into my router...
This morning I went to log onto my router to change some settings and when the password screen came up there was a CAPTCHA thing there that had never been there before.
I tried my password with the CAPTCHA, said wrong user name or password
I tried my password and left CAPTCHA blank, said wrong user name or password
I was in the router maybe a week ago or so looking over settings because I kept losing my internet connection. I was sure it was at the providers end, they said it was my router. Maybe they were right after all.. But anyway, I was able to get into the router fine before.
The only thing I can think of is that recently the power at the house went out. Could this have somehow reset it?
I don't recall ever seeing the CAPTCHA thing before...
