Or you can click on "choose file" when your reply and add them one at a time.
I'd also make sure to include the cable connections page with the logs.
okay I just got off the phone with netgear and the agent said that my downstream channels are good but my upstream channels are using a lot more power than they should. She told me that the power levels should be around 35 dBmV to 40 dBmV. Here are mine for my upstream.
She said it was either my coax line or something my isp can push through to see if it fixes it. So I called my ISP and I have a tech coming out tomorrow to check the coax line.
Power 1 Locked ATDMA 1 5120 17600000 Hz 51.3 dBmV 2 Locked ATDMA 2 2560 25600000 Hz 52.8 dBmV 3 Locked ATDMA 3 5120 30400000 Hz 57.5 dBmV 4 Locked ATDMA 4 5120 36800000 Hz 53.3 dBmV The 57 is high. the rest are technically within spec. Its tough to know without all the data because if you're downstream power levels are low, it means that you're futher from the hub. That causes the upstream to need to be higher to send a signal back to the hub.
the only time i see people with their upstream at 35 is if they're right next to the hub.
do you have a full screen snip of both the upstream/downstream and the correctables/uncorrectables?
As well as your logs?
that's a better way to check. you can add them one at a time to be viewed
