Same error as everyone else, try again later...

I was able to sysupgrade just last night. I was getting an error, but everything worked after bouncing (power cycle) the modem. I wonder how much memory you got left on that device?

4

The wget 8 errors are occuring up on the ASU server, so memory leaks or file handle leaks or whatever on your local device should play no role here.

5

If you are having server errors I figure, you tried to ping it.
Do not forget, from time to time I have experience the server reporting errors.
I have the same router you have using AT&T fiber and I am not getting the error you are reporting.
Actually, there is a threat about sysupgrade errors, habe your try checking it?
