unstable ethernet

yellow light on my superhub for the past 3 weeks my internet has been dropping very often for short times, wifi doesn't seem to have an issue. tried factory reset of router, tried manual reboot of router, checked all wires are connected. i have had a really bad experience the past month with this not being able to do what i want to do.

Re: unstable ethernet

BQM looks ok so far. No evidence of network dropouts - so is it just wifi connections that are dropping out - or do ethernet connected devices drop out at the same time.

Re: unstable ethernet

Try a new Cat6 ethernet cable if you haven't. Are you connecting through a "switch"? Have you tried all ports on the Hub?

Can you do a quick check that all of your coax cable connections are in nice and "finger" tight - at the Hub and wall box and also at any connectors etc. Ensure there are no “unterminated cable loose ends. Disconnect all the connections and reconnect to be sure. Also check that the internal wiring is ok with no kinking or chaffing, check that all looks good with the outside cabling and wall box.

Finally, Post up your Hub/network connection details and someone will check to see if there is a problem there.  In your browser’s URL box type in http://192.168.0.1  (or http://192.168.100.1 - if in modem mode) and hit return. On the first page up [there should be no need to login if you have done so before unless you have the New Hub4 when you do] click on the “router status” icon/text at bottom-middle of first page up and then copy/paste as “Formatted Text” (not images) 3 FULL sets of data onto here – 2 pages from the Downstream, 2 from the Upstream, & the Network Logs page. Don't worry too much about the formatting it can be easily read & DON’T include personal data or MAC addresses - blank them out - if you copy/paste the data, the board software will do this for you (you may need to click the "submit" button again.

Re: unstable ethernet

You have connection issues that only a tech visit can sort. Many of your down power levels are too low -6dBmV is the lowest recommended level. Also the Up power levels are at the top of their recommended range. The RS errors may be an issue too. So call it in as a fault and see what they have to say when they check the connection. If you get sent to a reboot message and then get cut off - call back 5' later on the same phone they system should know you called in, the reboot did nowt and thus are calling back and so put you into the queue.
