Is it normal to have -9 power and millions of correctables and uncorrectables after a week of use(used to be several hundred trillion before changing the 22-year-old old coaxial cable)
Just keep an eye out for it, but if the error rates are low now after swapping your old cable, you should be good.
Low power isn't that big an issue - pretty much -15 to +12 works, +/- 10 is better - closer to 0 as possible.
I'd check for unnecessary splitters, reseat all connections, and essentially verify the internal wiring. Error rates that high usually are bad, most of the time you are shooting for an error rate in the order of 1e-07 or lower over several weeks of use. Should definitely be less than 1/1000 within 1 hr of any reset.
There are no noticeable speed degrations or problems though (speed actually max out 425) latency is 7ms
