Re: Intermittent internet outages

I am having a similar problem - intermittent loss of internet connection for one or more devices.  I would like to pin down the timing and circumstances of these glitches, but I cannot find how to start the "event log" of my new Arris SB8200 cable modem which was bought to replace an older modem which had the same problem.

Please advise on how to enable event logging.

With thanks.

Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers along with the error log entries in their entirety.

Re: Intermittent internet outages

The stats are o/k. Error logging should be enabled by default. Perhaps there just aren't currently any errors ? You can test this by power cycling the modem. After doing so, there should be some start-up error entries listed there.

Re: Intermittent internet outages

Here is a partial list of recent events from the log.

The three error types keep repeating at about 1 minute intervals.

Also now, the status is showing many corrected and incorrectable errors across all channels.
