Copy the Downstream and Upstream table and paste it into a post.  Copy the tables as you would if you were copying text from a document.  The copy and paste process will paste in the text contents of the tables.  Don't worry if it looks a little strange after pasting it into the post.  I'll sort it out if necessary 🙂

Re: Cisco DPC3825 Gateway

Yes but at this point things are ok. When things are ok I can log in to the modem and see these readings but when it starts acting up I try to log in but the login page shows as being unavailable. Is the only way to fix this to bridge the modem and use a separate router? I didn't mention it but when things go bad I can't even log in with a direct

wired connection. Also the Rogers support people couldn't get in until the gateway was rebooted.

Re: Cisco DPC3825 Gateway

@turkk if the modem becomes unserviceable, call tech support and ask the CSR to run a signal check on the modem.  If he or she can't communicate with the modem, then there is a cable and/or connector issue afoot. That requires a tech to determine and repair/replace.  A modem reboot will temporarily resolve cable/connector issues but it won't fix the underlying problem.  Its pretty simple .... no communication with the modem ...... send tech.

Re: Cisco DPC3825 Gateway

At the time that they can't connect I can still use the internet but it will drop out. When the techs come it isn't in this state

Re: Cisco DPC3825 Gateway

Sounds like an intermittent signal issue, which is one of the worst issues to deal with.  If it finally quit, it would be easy to find the problem and replace the offending cable or connector.  Until then all the tech can do is check the signal levels and replace various connectors to resolve any possible issue with the current ones.  Is your external cable an overhead cable from a utility pole, or underground to the house?

This is a condo building and I believe all services come in underground

Re: Cisco DPC3825 Gateway

Right now gateway seems locked up so i can't login to it even hardwired. Internet is still functional but getting iffy

If I call CSR what should I ask?
