20M : Internet keeps dropping out

[AlabasterLyn]

For the last few days I've noticed the internet keeps dropping out. It must have happened 3 times today already. When I check the modem the ready light is flashing, so I am guessing it's not a router problem.

I have no idea what the modem readings should be, so I will post them to see if anyone can give me an idea if something is wrong. I do seem to notice a lot of stuff on the logs that makes me think all is not right, but as I said I'm not very technically minded.

teh ready light flashing suggest something is causing it to cut out, bu nothing there suggest a reason why, next tiem teh ready light is flashign log into th mode and get the same information please and copy it to notepad then paste here when oyru back online

[thenry]

There might be work being done in your area. Have you noticed anyone at the cabinets?

Your modem might be shot...

[qasdfdsaq]

Or the service could just be inherantly crap. Or full of cloners.

I didnt read the log.. firmwares been updated. Has it installed correctly? The OP may want to manually power down for a few minutes then power up again.

[Andrewcrawford23]

reading the logs suggest it is upstream issue it not lockign the upstream the firmware update could be a caus eof it but i agree with oyu henry power off for 5 minute and power on hopeuflly it iwll reapply the firmware and fix it

my internet has been on and off since sunday morning
well its always "On" but it seems DNS is the issue as no names resolve but doing anything via a IP works fine.
a reboot of the modem fixes this for 10-15 mins

[Andrewcrawford23]

in that case i suggest using google dns or open dns

[SOSAGES]

yes i have been but nudging VM to fix it..
