recently internet comes and goes, speedtests 4-5 mbps up to 260mbps randomly.  Then off for several minutes or longer.  Then it returns?

Typically a delay then it shows  ip address not found, then the webpage appears?

speed test might not load for several seconds, side advertisements fill in slowly then speed

is less than 10mbps.

Next time speed approached 300 mbps.  possibly followed by no internet for several minutes or longer.

'Is this a local problem?  I am in Fairview area of Nelson.
