Sudden rise in packet loss to 30%

Morning everyone.

I'd like to report a sudden loss in connection quality that started at 11:45pm (ish) last night.  My connection has been fine for some considerable time and then last night dropped completely for around 15 minutes. Once reconnected it looked like this...

I've checked my PC and rebooted the cable modem with no improvement and there don't appear to be any known service interruptions in my area.

Any suggestions ?

Re: Sudden rise in packet loss to 30%

Keep an eye on your downstream power levels mate.

One is at 9.1 and others are at 2.1 thats too large a difference.

They should be between power should be always between -6 to +10 and as close together as possible.

Also you upstream modulations should read 64QAM not 32QAM.

Have another look to see if they have sorted themselves out.

Re: Sudden rise in packet loss to 30%

Do the downsteam/upstream levels levels still look out of whack to anyone?

 

I appreciate the help!

 

Thanks
